Doubtless some will have bad sectors by now. Here's a rescue tool:
http://bim.bsn.com/~jhs/src/bsd/jhs/bin/public/valid/valid.c & valid.1
`Valid' runs on FreeBSD, but only rescues when running on MSDOS !
(because read() on DOS3.2 returns the intact buffer even if the
CRC fails, so I can then average each bit of each byte in each
sector for all reads). `Valid' works at sector level, no knowledge
of file systems, so it can rescue/ manipulate BSD FS sectors on
floppy, tar images, DOS or Minix file systems etc.
