    I suspect that there's a strong probability that the media flaws with expand over time, so this may be a fool's errand. (I've been caught in those)

    It does not complete. It gets to about 10% (or around cylinder 40-something) and then just drops back to the prompt with "Format Failed". I may try to hook it back up and try Speedstor, just to see if it makes a difference. But I suspect this thing has been sitting on a shelf for too long probably.
    I was planning to put in an XT-IDE anyway, but just wanted to see if I could resurrect this old drive first...

Depending on the controller, it may add that to a bad track list and should give you more meaningful error messages. That by itself might not make a difference, but if you then use SpeedStor's partition creation tool it should stop you if a bad sector would wind up in a partitions FAT or root directory. If it does that, try creating a smaller primary partition.
    Hmmm.. I think that may do the trick, even without Speedstor. If I tell fdisk to create a primary partition that is < 38 cylinders in size (should be large enough for a DOS boot partition), then created the extended partition in the rest of the disk. Logical drive D, small again (cyl. 38-40-something), and never format it, logical drive E starts after cylinder 40-something.. Maybe that will work... I guess I'll have to try that this week sometime!

    It kinda sounds like Track 0 might be hosed and if that's the case there is little to no chance of getting any partition table to work.

    Track 0 (Cylinder 0, head 0) can't be hosed; otherwise you couldn't write a partition table and DOS wouldn't start a FORMAT operation.

    That being the case, you can start the boot partition pretty much anywhere.

    Personally, I wouldn't bother, however. Chances are that the situation will only get worse.
