    dd_rescue problems


    Hello everyone.

    im trying to recover a bunch of 320gig harddrives using dd_rescue, using Suse linux. most of the drives recovered just fine, but on some of them i always get errors like the following:

    hde: dma_intr: status=0x51
    hde: dma_intr: error=0x1 {AddrMarkNotFound]

    that ^ repeates many many times with slightly different errors, then i get this

    ide: failed opcode was: unknown
    hde: DMA disabled
    PDC202XX Primary Channel reset
    ide2: reset: success

    and then the computer completely locks up and i cant do anything. I realize there are going to be errors, as they are bad hard drives.

    It only seems to lock up after this part of the errors
    ide: failed opcode was: unknown
    hde: DMA disabled
    PDC202XX Primary Channel reset
    ide2: reset: success

    so my question is, can i STOP the kernel from doing the ide2 and or Primary channel resets? i think if i can stop that, i can just let the errors keep goign and dd_rescue can continue. any help will be greatly apreciated, thanks

    I have already tried using hdparm to disable DMA, i get the same results only it freezes faster (i guess because it skips te dma stuff)
