One method of skipping bad sectors on an iPod's drive
Authored by: reynhout on Mar 09, '06 11:19:29AM

Just for the record, typing "0s and 1s" (or even numbers at all) can't be important.

The on-disk representation of the file will be functionally similar even if you use MP3 data. In this case, you want to use something that the iPod won't try to do anything special with (so not an MP3), but a 1MB gzip file is just as good as anything else.

Also, does anyone know if Apple makes any attempt to defrag or otherwise manage the filesystem layout on iPods? If so, this hint might break when that management occurs.

In 80s, when disks were less reliable, good ones (SCSI) would store a bad-block map in the first few sectors of a drive. So the disk itself would know which blocks to avoid and the master device wouldn't even have to think about it. I don't know if that's true in newer EIDE drives, and I don't know what how the iPod addresses its drive...but apparently not that way. :-)

Good old fashioned "mess with it til it works" work here.
