Ghost will indeed ignore the bad blocks and attempt to write to them :(
If it was a SCSI hard drive you had (or maybe some types of IDE drives?) you
would not have this problem...
From what I recall of the FAT filesystem, the bad block information is kept
track of by DOS/Windows, not the hard drive. It`s part of the file system.
When you use Ghost, Ghost will just try to restore the filesystem information
from the partition it has an image in. It will not look at pre-existing bad
block information. Perhaps there is a way to get it to do so but... err, I `ve
never used Ghost so can`t help you there. Sorry.
For some reason after my 2nd attempt at running NDD, ghost managed to restore the image. Nothing on this drive is any importance, so this is just an exercise in education. Running NDD a 3rd time on the restored partition revealed the bad blocks again. So yeah... it seems you're right about the info on where the bad blocks are located is in the OS files somewhere, not on the HDD.
A SCSI drive does bad block revectoring i.e. there are a few hundred or few
thousand blocks `reserved` for use when a block goes bad... details of the bad
block are stored in the drive`s firmware, and it revectors attempts to access
that bad block to one of the reserved blocks. IDE drives, as far as I know,
don`t have such a feature.
It would certainly be a worthwhile option I would think.
Perhaps you might be able to get something working if you can either a) tell
Ghost to use the pre-exisiting bad block information, or b) tell ghost to
ignore bad blocks (if you can) and then deal with the problems once you`ve
restored the image.
I may just create a small hidden partition to isolate the area with the bad blocks that seem to be all in one spot... like creating a partition to deal with the Windows hibernation data.
BTW have ordered a Libretto case from someone in Canada, including screen
cable.... Maybe I will get the thing to work after all! or maybe I will find
out the LCD is bust :( Speaking of which where can you source LCD screen
replacements? :(
Seems like Impact in Miami had the best prices on Libretto LCDs:
http://www.impactcomputers.com/toshiba-libretto--70ct-parts.html
But no one has posted anything about purchases from them to my knowledge. And at $349.95 it'd be cheaper to pick up a whole new 70 on Ebay.
Good luck.
Matt
