    Hi candy or whomever might be able to help me.......

    Im getting first a black screen then a bluescreen with the following error

    "Unable to write to disk in drive C: Data or files may be lost. Press any key to continue"...

    this error started a couple of weeks ago & is getting worse everyday. I first thought my harddrive was overfilled... but after checking I know thats not the case. I have read others horrid tales of this error... & my abilities are even more limited than some of those that have tried going to bios etc...
    OS is WinME 40Gb partitioned to 2 drives with C being
    15.9 capacity with 9.65Gb used... and D is 21.3Gb with 13.2 used.
    I did a thorough scan disk... nothing shows. I did a defrag less than 2 weeks ago & it was fine then. I will do a defrag after leaving here... anyone have any simple advice. I do not want to fdisk & reformat til i can try to back some of this up... save it somehow...

    thanks in advance

    Hiya Savvy :D

    You may be experiencing a Cascade Failure of the Hard Drive!

    Go to the Hard Drive Maker's website and grab the diagnostics program and run it!

    If you want one that will work on multiple drives/systems...

    Go to Gateway.com and download GWSCAN.EXE

    This is what they use to diagnose different brands of HDD's in the systems.

    If you have a Western Digital Drive, go to www.westerndigital.com and download "Data Lifeguard" and run it.


    Hope this helps!

    Good Luck!

    ok... I installed & ran the Seagate diagnostic... everything was ok on even the long test... also I installed S.M.A.R.T diagnostic... but only the trial version... Im getting all kinds of readings but don't actually know what the attributes are supposed to be set on exactly...

    anyway... so far I have found nothing... except maybe a need to clean the fan as I think it might be overheating if im reading that thing right... I however,,, don';t have a clue as to what temp is to high... and its telling me in Celcius not Fareheit..

    then I went to PCpitstop & ran the diagnostic test there.

    I have a red flag on disk performance... ( bad thing a red flag )

    after a thorough scan & fix & defrag this is what I got......
    test show >>
    Cached speed 237.64 MB/s (99%) 240.96 MB/s (100%)
    Uncached speed 2.35 MB/s (40%) 2.54 MB/s (43%)
    Drive health OK ....

    It indicates that the uncached speed is way to low.
    ( TechExpress link for current results:
    http://www.pcpitstop.com/techexpress.asp?id=CQ78GWTNJNLSBK6B )

    So now how do i fix that?

    You didn't say what the temp was......

    But if you are getting this error more frequently, I'd start backing up anything important......what brand is the hard drive?

    In your bios settings, do you have the option to enable SMART checking there?

    It honestly looks like either the hard drive or the motherboard...

    can you try a different hard drive?

    If the diagnostics say it's ok, then there may be an issue with the drive controller.

    Change the IDE cable before replacing anything else tho...I've seen bad cables cause some weird issues!!!

    Yes S.M.A.R.T. is enabled in BIOS............and no error from that. I haven't got the blue screen today either... after thorough scan & defrag... the trial version of smart indicates heat at 40*C which converts to 104*F

    IDE cable (controllers?)... I know nothing about that either... do I need to put this in a shop?

    This mornings test at pcpitstop says ...

    Unusually low disk performance

    Drive C has an uncached speed of 3.62 megabytes per second.

    Drive D has an uncached speed of 3.45 megabytes per second.

    For comparison, systems with the same CPU, clock speed, and memory size as this one have an average uncached speed of 5.92 MB/s .
