Nokia N91: “Hard Drive Unavailable” Possible fix

HI,

I recently had an email from Abhishek, who was receving this error message on his phone.

“Hard Drive Unavailable”

It didnt appear in the phone when He tried to access it  and this all started when he reformatted his phone.

The trick to fixing it as he had discovered was indeed simple.

*#7370#  this is a reset of the phone its self  and did the trick in this case.

Something i thought might help some folks out there.

    i have a problem with my nokia n91. “music player unable to access hard drive. Replace battery cover”. This message appers and I tried the soft reset and the hard reset but still the same problem. Every time I put back the battery cover my phone hangs. Without the cover my phone runs normal but the hard drive won’t work.

    Hi Guys

    Try either updating your software or re-installing the same sw you have (if you already updated) I bet the phone sw is screwey and its database cabt see the HDD

    MAC bukly had the like for the update

    I want to bye Nokia N91,but I heard that the HDD is causing problems…Can somebody who have N91 tell me should I bye N91?

  6. avishek

    Hey Don. I would’nt really suggest you to go with N91. I have been using this phone for the last 6 months alothough the sound quality is superb but have found alot of problems too specially with HDD its very unstable i have heard that sony erricsson is coming up with its version of 4GB music phone check it out!!!!

  7. darko

    my hard disk all the time is Unavailable and “not formatet”. i format and it is ok ,but all the time is is unavailble

  8. ATA

    hey guys, im having this problem with my Nokia N91, any application or theme that’s its extention is .sis doesn’t work with it, and i get this msg “the application …sis is not supported”
    please help me, i’ve bought the phone last night, and it’s brand new.

  9. Voda1

    Hi ATA

    Remember this is a S60 3.0 device. old sis files will not work they must be signed sisx files

    regards

  10. Voda1 you are incorrect, the Nokia N91 supports .sis & .sisx written for the Series 60 3rd Edition Platform.

    .sis application installer files can be digitally signed aswell.

    FIXED IT !!!!! Having read all the comments here …. and have found them Very helpful … I have come 2 the conclusion that the fault is in ” Nokias ” software , ie it is useless … Just like the old Nvidia drivers … Sometimes u have 2 go back 2 the previous ones , As the new ones were duff !! . I found that the only thing that Fixed/Repaired My phone was 2 do a ” Full Format ” !! Sry if that was not what u wanted 2 hear !! I tried a Quick format … And it said ” Corrupt hard drive !!! Did a full one and Hey presto …All is good again . Save ur phone numbers , messages etc first , and wipe it clean Baby !!!!!! And DONT REINSTALL THE DRIVERS >>> THEY R CRAP !!!!!!!!!!!!! . Love n Luck .

  26. Nikola

    I’ve have the similr problem.When i full format HD it works just fine…for a week.Then some songs and file cdouldnt be played,and than more.Eventualy, it crashes and then i must format HD again.After a couple of days same old story (HD corupt again).I don’t think that HD has bad sectors because it work just fine when i format it.I think it’s software (although my fw is 2.10.013 RM-43 N91 (02.01)

  27. jamalo

    this is the worst nokia phone i have ever seen!!!

  28. awwal

    pls can anyone tell me what to do with my n91 hard drive

  29. Nikola

    i think its software problem becouse when i format hard it works for couple days and then bam!I cant find anything about this problem!Sometimes it works for 2-3 days, sometimes for 4-5 days but eventualy hard fails and you must to format. I’ve have this problem from day one since i bought this damn phone.Shame on people from Nokia for not telling this.It’s so anoing!Does anyone try to take phone to service?if they do not know who does?

  30. Nikola

    for mohammed:Does new firmware solved your problem?Becouse my version is 2.10.013 and that is newest firmware.For n91 8gb its 3.00 something..Does someone with n91 8gb have similar problem?This phone is my worst investment ever!

  31. Nikola

    there is new firmware vor n91!. it’s 2.20.01.Maybe this wil resolve hard disk problem.does anyone update to this firmware?

  32. Magosla

    I have a N91 phone. I updated the firm ware to 2.20.008 and i worked fine for about 10 hours when i later tried to access the Hard drive it was unavaillable so i switch off the phone and switched it on & the phone became unstable it stands by and later comes up within a space of 5 secs continously. when i remove the battery cover it becomes stable but still cannot access the hard drive. I have tried reseting the phone but it does not help. Can someone help me on how to resolve the issue. if it is to reinstall the phone software where can i get the software to reinstall

  33. Nikola

    My n91 is working just fine for 12 days now (this is a personal record) and i still not update it to 2.20.008.I think this is becouse i didn’t install any third party applications!.Every time in the past when my hard breaks i formated it and then transfer some music and install some aplications (smart movie, mweather, etc).But this time i didn’t and now i have no problems!
    Magosla, did you install any application?
    Did you tried *#7370#? reset or…?
    Does your phone gets reaaallllyyy slow?if this is the case, , you should wait, activate hard disk tool (this will take over 30 min and then format). This was my problem in the past!

  34. Abrar

    Edgar,
    regarding the problem of replace the cover.
    i read this somewhere. don kno how far its true.
    the cover is magnatised. the phone shud detect the magnet to activate the hard disk. check whith some metal pins if the cover still got the magnet power. if not u will have to use an externel magnet and magnatize the cover. try it.

    N91 Hard Drive problems?

    dont make me laugh. Just a word of wanring regarding the N91 HDD.

    1) DO NOT install apps to the hard rive if at all possible.

    I have had two crashes now. with hard drive unavailable and corrupted. It seems to happen when I add music to the n91. The problem is this (Nokia take note) if u add music to the n91 whilst an application on the hard drive is running, when the music playlist starts to update, it cannot get exclusive access to the hard drive. So the header gets corrupted as the write command is interrupted by the application trying to read at the same time.

    What happens basically is your HDD gets screwed… MAJOR oversight on nokia’s part. You will find that your phone reboots and then become EXTREMELY sluggish. this is due to the application is trying to run from a corrputed drive.
    once you remove the application, the phone speeds up to normal.
    The only way to recover from this is to format the drive..

    anyway have a nice day.. that’s my 2 cents.

  36. Nikola

    I still haven’t install any aplication so far (Just 2 gigs of misic) and my phone is runing great for 3 weeks now.That’s all

  37. saif

    my n91 is great. i have had no problems with it, ive ad it for 6months now and still not even a lil mess up… i use the phone alot, internet, wireless n everythinggggg and not even a harddrive messup… maybe its just the hardware of ur phones that are no good?

  38. Rumi

    I have lost my n91 battery cover.After that I faced same prob hard drive not available.
    I Know that the battery cover has a magnat and it create magnatic field at the battery area( the hard drive is situated under the left side of the battery). the phone should detect the magnet to activate the hard disk. So I attach a small magnat with tape at the battery and restart my phone and hdd is available again and works fine. so if u people faced hdd prob then check the magnet is ok. If not, replace the battery cover with a new cover for solve the problem or try it with a small magnet like me. Best regards.

  39. Rk

    My Nokia n91 has caused problems non-stop since i bought it, today tho, it has decided to stop working completely, i tried installing the stuff from nokia’s site but it just fails and then i t freezes when i try any buttons, won’t even let me read texts or make calls, i used to love nokia phones but now i’ve lost faith. They’re swimming out of their depth.

    HI EVERY BODY…
    I’LL TELL YOU A MASTER SOLUTION THAT
    WILL SOLVE MOST OF YOUR PROBLEMS
    1-CONNECT THE MOBILE WITH THE COMPUTER IN MASS STORAGE OPTION
    2-THE MOBILE WILL APPEAR AS A MOVABLE
    DRIVE IN MY COMPUTER WINDOW
    3-RIGHT CLICK ON IT’S ICON, THEN CHOOSE
    PROPERTIES.
    4-CHOOSE TOOLS TAP
    5-CLICK CHECK NOW.
    THE MOBILE HARD DRIVE WILL BE CHECKED
    AND FIXED FOR ERRORS AND BAD SECTORS.
    6-AFTER CHECKING PROCESS YOU MUST FORMAT(FULL FORMAT) THE HARD DRIVE BY THE PHONE ITSELF(NOT VIA COMPUTER).
    NOTE: ENSURE THAT THE BATTERY IS FULL CHARGED BEFORE CHECKING PROCESS AND BEFORE FORMATING PROCESS.
    I USED THIS METHOD MYSELF AND THE PHONE IS ALLRIGHT NOW……
    GOOD LUCK.

  51. aytunc

    Ahmad, that would be a good suggestion only if you could connect ur phone to the comp in mass storage mode when the hard-drive is not in accessible mode.. thats the problem.. not being able to access the harddrive. I guess the ppl whose problem didnt get solved with the magnetic back cover solution has a hardware problem 😦 restart the phone without the back cover and later on put the cover on adn listen closely to the phone. mine makes some noises from the HDD. so i will take it to the technician 😦 but if there is a software solution that would be a miracle

  52. sumeet

    hi i am using this phone sine a year there was many consequences with my hard disk many time while listrning music it hangs and says hard disk unawialable. but many times i did the sam as mentioned above and it was ok. but now from a week i am facing a problem which i cant solve now when i am loading the songs after dissconnecting from pc cannot operate the phone it gets stuck
    and if u restart it agan without battry cover it works ok
    but the harddisk show not formatted
    pls help i am feup of it and i will not recommend it to any one

  53. Julio

    Hi everyone. Well I think we all agree this Nokia N91 is rubbish. Mine decided one day to say “Hard drive is unavailable”. When I tried to format I can’t because this option is unavailable. I tried *#7370# but it’s still the same. Can anyone give a solution? I suppose I will have to take it to repair or send it to Nokia and tell them what they can do with it…
    If anyone can provide a solution…
    cheers to everyone from Barcelona (this is starting to be an international problem :-)))))))) )

  54. erick

  57. Jagster

    Hi Guys…

    I’m having problems with my N91. I admit it was my fault to try to change the font following a certain instructions just by placing a new directory on the hard drive E:\resource\fonts. I put some fonts inside that directory. and restart the phone. The problem is– I cannot put the original fonts back. Whenever i delete the directory on the hard drive, it says error -46. I even tried resetting my phone and try formatting the hard drive thru the phone. It always says hardware in use. I can’t even shift to mass storage drive. I tried copying the original fonts on the e:\resource\fonts but it says error -46.
    I need help badly. Thanks!

  58. K K

    hi all,
    after readin all this i think i have done a big mistak
    i bought a N 91 yesterday itself
    now i cant retun it.
    Jus prayin to god that it want giv me a prob.

  59. pezmick

    Hi there everyone i have read everybodys comments and the first thing i would like to say is dont panic. Firstly upgrade your firmware to V2.10.013 21.09.06 RM-43 n91 (50.01) backup your HDD using PC Suite 6.84.10.3. Then do a full format of your HDD, restore your backup, restart your phone and bingo, a perfect working HDD/Phone, well mine is anyway. Personally i would email nokia and insist on them sorting out your problems, as SOME of you have paid a lot for the phone and it dont work right. Good Luck one and all

  60. Swed

    Don’t buy Nokia!!!!!!!!!!!!!!!!!!!!!!!!!!! I have a n91 this phone was the biggest shit i have ever

    Hey dudes

    I have a problem with my n-91. Even when there was 3 gig worth of music on my [hone it would constantly come up as there was nothin there. I checked all my other files, and low and behold there where no pictures or movies either. I formatted my phone to hope that would work. But no it didn’t. Whenever i try and use my usb to transfer data to the n-91 it says to insert portable E device……… When it’s clearly attached…………. Can someone please help me with this. I bought this phone for the Mp3 and now it’s stuffing up hardcore.

    Cheers

  62. Moataz

    i had my n91 for a long time, it was working fine according to the rules of healthy using to the hard drive, one day i was bored out so i made a major mistake, i upgraded my firmware through nokia’s site to v2.20.008, now my hard drive always shows not formated, and if i try quick format/full format it crashes and restart plus as a combo for my disaster now i hear the hard drive ticking like hell when the mobile starts, it take ages to start the mobile, and if i want to fasten the operation i had to start it with no battery cover then place it back, i knew there is no roll back for firmwares so i cant restore mine, now i’m stuck, so …. HELP!!!

  63. Wajeeh Azeem

    my phone has the problem of the Hard Disk which is quite common in all the Nokia N91 phones. But besides that it often says that ” switch off device before removing battery.” is there any solution to it.

  64. Stifler

    Hey folks,
    I am facing this problem since I have got N-91, I was just going through the couple of thread above, most of the ppl are suggesting about Full format.
    I agree it works but Hard formating decreases the lives of Hard disks. SO Please Please do use this feature only when you have no option left.

    I would rather suggest precaution for not having this error that its cure.
    1. Please do not load too much of data though the 4GB is available
    2. Please be careful when you take a video shoot. There are more changes of hard drive failure when you are taking images and videos for a long time.
    3. Any time you feel that it hang, please do not play around and if possible immediately restart phone.

    These things avoided the HDD error for my N-91 since 2 months and I am happy now…
    Best of luck if this helps

  65. i have see a lot of you clues but the problem here is that i cannot do the formating because the battery runs down quickly and becomes very hot,is there any other way please,the phone is so hot that it can even burn ur hands

  66. help me out ooh,i just tire for myself ooohhhh,i like the phone very much and i can’t affford to loose it, and also waste the money that i used in purchasing it

  67. DAMN NOKIA, I DON’T KNOW HOW THE COMPANY CAME ABOUT, MAYBE THE COMPANY CALLED NOKIA WAS ESTABLISHED DURING THE TIMES OF THE ANCIENT MEN,I CAN QUITE SEE THAT THEIR ENGINEERS ARE ALL APES,THEY ARE ALL FUCKERS,IF THEY DO NOT KNOW WHAT THEY ARE DOING,THEY SHOULD PLEASE GO AND FIND A BETTER JOB FOR THEMSELVES.JOB LIKE DRIVER A CAB NOT PRODUCING A PHONE COS THEY DO NOT HAVE ANYTHING IN THEIR FUCKING HEAD BECAUSE IT IS ALL FILLED UP WITH HOLE,PLEASE ANYONE WHO KNOW AN ENGINEER WORKING THERE SHOULD PLEASE TELL HIM TO LOOK FOR A BETTER JOB, RIGHT NOW BASED ON THE PROBLEM THAT NOKIA HAS GIVEN ME I AM PRAYING FOR THEIR DOWNFALL,IF YOU ARE USING AN N91 GO AND THROW IT AWAY BECAUSE IT IS USELESS AND MEANINGLESS,I AM GETTING FREAKED UP BECAUSE OF THE PROBLEM THAT MY NOKIA N91 IS HAVING,MAKE UNA DO WEELL OOOOHHH

  76. Verzigathor

    well guys, bad news, i’ve heard somewhere that there is no fix to this problem and it gets worst with time (till now just goold old known news). nokia hasn’t yet found a good indeed solution to this HD problem and they are going to drag us down as this model of N-series gets forgotten by everyone! e really love My n91 but i se my self in a position that forces me to sell it to someone with no knowlege of the situation here! THAKX NOKIA FOR MAKING ME SPEND MY MONEY IN A PEACE OF S*I*! for now only doing windows scandisc on N91 HD has proven to solve the problem for mere (max), 10 days (personal record). farewell my friend and good luck, may nokia emprove there ways of fixing problems like this in this new year LOOOL (doubt it). [[[]]]

  77. oni

    guys, if your n91 came from a bad drop (about a meter or so from the ground ) hard drive errors may be encountered. The trick is to open the phone, fix the contacts between the hard drive and te main phone board which are not soldered, rather leaning wire contacts were used. It worked for my phone. Opening is easy, the hard drive is accessble.

  78. lee

    i try to open my nokia camera and it comes up with a message saying general feature not suported ive tryed to up date the firmware but that didnt fix it ive tryed to reset it but that didnt do it what should i do please help i love the phone its great

  83. nimsah

    I don’t know what else to do with my N91 phone. I always experience HD unavailable and system error as well and then phone hangs. And when I put the back cover the phone over heats and the battery gets easily drained. Without the cover it doesn’t over heat but the HD is inaccessible, my technician had the HD removed to avoid over heating for it might cause more problem if he’ll keep it active. any advice? right now I don’t have access to the hd for it’s disabled, still getting the system error message though…any help is much appreciated.

    I’m fed up of this phone already, having the same problems as many people on this page, ‘Hard Drive Cannot be found’, ‘Please insert hard drive’ and the like, tried a hard reset, and with the thought that I needed to input all my contacts for the second time to my dispair the hard reset hadn’t even solved the problem, Nokia??? you used to be a good phone company, if there is such a problem with this stupid little phone, (well, masssiveee phone) then why keep it on the market?? I am getting more and more dissappointed in you. :/

I’ve formatted my hard drive several times, phone memory is also perfect infact I’ve got NOTHING in my cell. It is slow in messaging either. I am hell worried.. 😦 Help me please.

  108. rupak

    please suggest me a way out…. i own an n91 for more than a year now.. i hav been more than pleased with its performance but recently a problem has appeared! the keypad was loched for sometime as i was on my bike. the cel was in my pocket, probably under pressure. after i took it out, it started malfunctioning. some keys were not working. i thought of it to be a keypad problem. but at night when it was left alone for quite a long time it started to scroll ang call all by itself… after sometime it was alright… but recently the problem has started again….

  109. Lucky sylvester

    Hi. I use n91 wen i tranfer video after dat it keep telling me hard drive unavailale, replace battery cover. Pls someone should help me out. Sylvester

  110. Rolen

    This is the new technique that will help solve the problems when phone totally cannot access, while using 4 gig hardrive. Many says it hangs up, but the truth is it cannot read the hardrive, use this technique!
    1. Switch the phone on withouth the cover.
    2. The phone will turn on nicely. Then immmediately put the cover.
    3. The phone will beep and starting reading the hardrive, before it hangs be fast to click it off.. If it does not turning off, repeat the process because our goal here is to turn-off the phone while it is not hanging.. By these means it restart the hardrive,.
    4. When the phone succesfully turned off.. Turn it on again, this time with the cover.. And you will notice that it will open smoothly!
    I have n91 my self and encountered 3x problem regarding hanging n91, i did this tecnique 3x and presto! it works just fine.. Now i am confident with my phone because n91 is the phone that have superior music player specially with the amplifier and stereo. Dont forget to thanks me.. Have a good day,.

  123. Arunabh

    hey there….the ” hard drive unavailable ” problem can be solved easily by the 2 methods : 1) *#7370# this is a reset of the phone

    2) The method of performing a hard-format, i.e resetting it completely to factory defaults and removing all data, is as follows:

    1.Switch off the phone.
    2.Hold down the following three buttons: Green (call answer) button, * button, and ‘3′ button
    3.While holding these buttons, press the power button and switch on the phone
    4.When the message ‘Formatting’ appears on the screen, release all of the buttons

  132. Chaey30

    I have been a loyal fan of nokia till I got my nokia n91 as a graduation present from my parents (since I pleaded for months) last 2006 when its still new in the market.. How I wish that I have asked sumthing else as a gift! DARN IT! 2 months its running great but then it began to have problems regarding the HDrive! HD not avail, Replace battery cover! When I tried to remove the batt cover it works fine but I cabt get access to the hard drive… I nearly threw it away coz its hopeless! I tried every advise and I went to the tech…but still cant fix it..Right now may u ask where it is? its here sitting in my room hoping to get attention from me coz now Im enjoying a different brand of cellphone… That’s the worst phone that I ever had! Thanks NOKIA for nothing! You should have a SORRY note or even swap old/defective N91 for free cellphone units (pref N series!) or YOU”LL GONNA LOSE UR LOYAL CUSTOMERS!

  133. good guy

    THIS IS THE ANSWER
    First try a hard reset *#7370#
    If it does not solve the problem you have to change the back cover as it has lost its magnetism.Replace with a 100% original back cover.NOT ONE OF THE KNOCK OFFS AVAILABLE IN THE MKT.That should solve your problem.ADIOS

  137. Ndy

    HI
    I GOT THE SOLUTION!!! for “HARD DRIVE UNAVAILABLE” problem
    1.Turn off your phone!
    2.REMOVE THE BATTERY!!! this is very important!
    3.Press Shift + F
    (F is 3 button) – I’m assuming that “shift” button is *
    I’ve allso tried other few combination with green button + 3, menu button + 3
    since I’m not sure which the “shift” button is.
    And Voila! you have a great music phone!
    Cheers!

  138. Ndy

    Of course I forgot to mention:

    4. Put the battery in place and turn on your phone
    (my phone stuck at the Nokia logo, but I remove the battery a few times and when he finally started I formatted the drive)
    5:……format…

    That’s it!
