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. Julian J.Stacey Munich Unix (FreeBSD, Linux etc) Independent Consultant Reduce costs to secure jobs: Use free software: http://bim.bsn.com/~jhs/free/ Ihr Rauchen = mein allergischer Kopfschmerz !
