The larger manufacturers have bootable floppy images for most of this sort of 
thing; most are included with the UltimateBootCD; no Windows required.  The 
Maxtor, Seagate, and Western Digital utilities can do the low-level sparing 
needed; in my particular case, the Maxtor diag's sparing routine wasn't able 
to spare enough sectors, and thus I have irrepairable surface damage; no more 
spare sectors.  But the drive, once badblocks is run, works fine and passed 
some heavy load testing and data integrity testing (again, when badblocks was 
run during the mke2fs run using -c).  SMART is not a happy camper, though, 
reporting that the drive's death is imminent; as it has been for the last 
year that the drive has been in service.....

Unfortunately, this particular 250G Maxtor was a retail drive with only a 
single year's warranty, and was ten days out of warranty when my power supply 
ate it.  But, really, Maxtor shouldn't have to replace a drive that died due 
to my cheap power supply, anyway.
