Hi. I have a few questions concerning bad block and track/sector re-allocation. I have a few drives that have sector 0 totally wiped out. What i wanted to do was totally re-allocate track 0 else where. I tried silverlining, LoDOWN, MicroNET, SUM, SUM II, Norton,and DPI. But all failed to re-allocate the track. It is a 145Meg Hard disk with a total of a couple of bad sectors. It succesfully R/W to the rest of this disk, but fails to boot and mount. Is there any solution to this problem. How can such a minor fault within say a 32 memory space write off 140mb disk. Is there a program powerful enough to actually analize this disk without crashing. oh well. Thanks in Advance. steveh

A bad track 0 usually means the drive is useless. -- Matthew T. Russotto russotto@eng.umd.edu russotto@wam.umd.edu .sig under construction, like the rest of this campus.

No, Not always. I fixed 6 sony's by re aligning track 0 to track 1. It worked, and still works. The bad track 0 has been forgotten forever... steve h

I have heard of a similar hack for DOS hard drives. It was described in the documentation for a hard drive utility called Spinrite. Basically, you create a DOS partition using, say, 10 cylindrers, which covers the boot tracks, then create another partition using some or all of the rest of the disk, this time a partition of reasonable size, and set this up as the bootable partition. They don't guarantee the process, and I haven't had to try it, but perhaps something similar could be done with a SCSI drive, maybe with Silverlining or some similar package. Anyone out there with a bad hard drive who feels like experimenting and would like to let us know what happened? This might be one of those undocumented features that will only work with certain hard drives.
