- Well this stuff about floppy defects is all very interesting, but how are
- hard drive defects handled?
-
- My hard drive format util, APS power tools 2.6.4, can be coaxed to print
- what it calls the "P" and "G" lists, which are lists of defects. What's the
- difference between the two? Also it has a feature that will scan the hard
- drive and remap bad sectors to good, without you having to reformat. This
- feature has a lot of problems (chief among them that it only works about
- half the time) but what does it actually do? My guess is that there is a
- list of bad blocks stored at the start of the disk and the disk driver
- checks this list for every block it is asked to read/write. Is this
- correct?
-
- And does anyone know of a formatting utility that WILL deal effectively
- with bad blocks that develop on Syquests. I mean one that will not only
- find them all, but will also tell you which files have been affected and
- should be checked.
