Replace electronic of harddisk

  1. Hi!

    My external harddisk (Seagate ST360014A) didn't survive the hot
    climate of the last days. I heard and saw a little explosion, turned
    off the drive immediately. Now it doesn't starting anymore, i.e. the
    disc do not rotate, but the electronic becomes very hot. I found a
    burned smd component (probably "fT 302 LEs", hardly readable anymore)
    and a bit of the plastic of one major ICs looks molten. I doubt that
    the IC is replacable.

    I would like to restore the driver to save the data on it. I looked
    around to get a replacement of exactly the same type, i.e. ST360014A,
    to use the electronics with the old harddisk. But the 60GB version
    seems to be unavailable (the drive is maybe 2y old). The 40GB
    (ST340014A) and the 80GB (ST380014A) versions seem to be available.
    They look exactly the same. So I hope that only the number of discs
    inside is different. What is my chance that those electronics will
    work with my 60GB drive? Are those electronics the same in one model
    line? Or do they use a special programming/firmware with every model?

    Thanks for your help in advance

    P.S.: Using a company which is specialliced in hardware restoration is
    much too expensive for my case. I saw prices like 500¤ per harddisk.

    Chances of a different drive board working are almost non existant; best to put
    it on a shelf until you run across the right board(it'll have to be the EXACT
    same board; mfr's often change/upgrade electronics during a model run, so same
    model # may be different drive)...

    If the materials, data, etc on the drive is invaluable to you, you may need
    to send it to a recovery station and have the data retrieved. Only other
    hope is what has alredy been addressed as to exact drive electronics board,
    inclusive of the eprom adressing.

    Even that may not be good enough since there my be a small flash memory on
    the board that contains a bad sector map.

    Seagate has a webpage listing resellers of out of date hdd's - expect to pay
    a finders fee!
    Of course there is always Ebay for finding out of date hard drives.
    Try to find the exact model, firmware and as close of a date of mfg as the
    data drive.
