Hard disk is not detected, even in BIOS

  1. Hello Guys,
    I was traveling home from school, about a week ago, so I detached my 40G Seagate hard disk from my desktop system,

    The hard disk contained some movies which i wanted my brothers to see.
    On getting home, my brother connected the hard disk to his PC and to my surprise, the hard disk was not detected by the BIOS, thought the harddisk was spinning all jumper settings possible was tried, and the situation was still the same.
    We even removed all other IDE hard drives, and left this hard disk as the only disk connected to the system, event at thsi point, the BIOS did not recognise it, so also did the OS.
    I thought it was a Board compatibility issue, so I decided to keep the disk until I returned to school. Now I'm in school, and I've returned the disk to it's normal position on my PC, even at that, my BIOS is no longer detecting it.
    I though it was a problem with the electronic interface of the Hard disk, so I got a similar harddisk, and switched their electronic boards, yet the situation was still the same. To make matters worse, my electronic board worked with the other hard disk.

    I have gone a step further by opening the disk compartment and switching their read heads, but now I even caused more problem because both hard drives are now in the same state - bad!

    Please is there hope of still recovering my data from the disk?
    I have over 13G of music, over 3.6G of eBooks and over 10G of Softwares!
    Someone please help me.

    "opening the disk compartment and switching their read heads"...

    You have to be kidding, right?? Changing outer control boards is one thing, but you need a clean room to open the disc compartment in. Both drives a paper weights now. When you get a chance, go out and buy an external USB hard drive to travel with in the future

    I do not think the hard disk can be repaired unless probably by the manufacturers.. Hard disks are meant to be specially handled in a special case. I think you have probably not handled it well which can cause a shock on the spin. Please never try to open your harddrive again..... that is intentional damage. it requires special technical treatment.
    The spin disk is too sensitive to be exposed.
    I would have love to help if you havent open it!........... see u later

    How valuable is your data? If it’s worth $3000 call Ontrack I’m always amazed by what kind of damage they can recover data from. If it’s not worth $3000, you have yourself a paper weight.
    On a side note, swapping actuator arms is very involved; you need special tools (not a screw driver) to prevent damage to the heads and platters.

    Do the drives still spin if so try to buy an external casing for the drives and plug them in to see if the USB can detect it if not like the guy said above as paper weight..

    Next time try to get external hard drive or USB flash disc 8GB or above..

    I only open hard drives I know are bad..

    My god... why on earth would you think you could do that and not stuff the drive?

    For example (altho I wouldn't take their word - it is something you have to be aware that could cause problems)

    I would say it is "highly unlikely" your room doesn't have a million times the dust of these rooms. ;)
