    My 250 GB SATA Seagate HDD is failing it seems
    Third replacement in Two years .
    However unlike the previous two failures ,this time SMART,Short and Long DST (Seatools bootable CD) didn't detect any fault .
    The problem I face is ,HDD gets uninstalled and reinstalled randomly .
    Today the drive has become inaccessible .
    Ironically I planned my Backup only Today . :(
    I have strong suspicions ,this is a driver issue .
    Any Ideas or suggestions will be helpful .

    Well if you have a caddy and another computer, you could mount it. If it works it rules out platter and controller (although its doubtful its platter anyway) and points to connection or drivers

    Nope I dont have either . My old PATA is more robust than the SATA .Bummer .
    Ironically ALL MY LINI ISO are in SATA .
    The Only ISO on PATA Is Natty which I will be using later .I am not too keen on dling Oneric . Hope I can salvage the data somehow .(Will make dd's )

    Are we talking desktop?

    You could replace the HDD then try mount it as slave.

    If its just data, run a live cd and get the data if you can?

    It could be any of a few issues - bad PSU, bad SATA connections, Onboard controller issues, etc.

    Even without a caddy, if you have a friend who has a computer that has a free SATA controller (Preferably a SATA II, as taht can handle both SATA I and II devices), you could test the drive and see if anything is wrong with it - I'm better no since SMART doesn't detect a failure.

    When you say it becomes disconnected, are you getting error messages at all?

    Also, what OS are you running on the machine? Do you have AHCI enabled?

    Yes we are talking desktop .(Forgot to mention it )
    Bad PSU and Faulty driver are top probables .
    Checked the connections and replaced SATA cables .
    I am running Win 7 x86 ultimate on my PATA .
    AHCI is enabled
    What I meant disconnected is the drive dissappears (As in unistalled or umount in linux )
    After a short while it reappears as new disk drive .

    I am currently using Ubuntu Natty from my pendrive
    I have 3 internal HDDs .1 PATA ,1 SATA 250 GB and 1 SATA 1TB.

    I will check the HDD on another computer .

    Backup completed in Natty .
    No funny stuff while copying .
    No failed mounts .
    No Nothing .
    Strange Stuff .

    All tests under Natty .No errors found .
    All tests under seatools dos .No errors .
    dumped zeroes all over the hard disk No error
    dd if=/dev/zero of=/dev/sdb
    dd if=/dev/urandom of=/dev/sdb
    Read speed /write speed .No errors .

    I think Wiping the HDD ,did the trick or something (One of X methods )
    HDD is working ok now in windows .
    Thanks for you inputs

    I had a feeling AHCI was involved as you were losing and then re-finding teh drive. it was either a driver issue, or it could have been something more sinister - such as malware (as in malware attempting to write to the MBR and being blocked and isolated by an anti-malware client, that then isolated the entire drive long enough for Windows to say "Oh, by the way, that disk you were planning on copying from? I just took it down."

    At any rate, glad it's worked out for ya - for now. PSU tester may not be a bad thing to invest in, though.... just in case.

    For future reference I would pay a company like SugarSync or some other to backup your data.

    I pay SugarSync $50 a year for 40 gigs of data space and unlimited PC links.

    If something happens and my data disappears or computers crash I simply resync the data and it all gets redownloaded, very reliable.

    $40 a year is not bad at all. I might look into that - I just blew 3 HDs away a couple of months ago, but I'm trying to buy a replacement HD that matches the others, then gonna install the exact same firmware and swap out boards ... and see if I can't do a little hardware hijinxing on the dead drives lol.
