Hello,
this error (see blow) occours, if I "fsck -c" (bad cluster test) a
medium in my parallel IOmega ZIP-Drive 100MB.
A complete dd from /dev/zero to the device works like a charm.
- fsck 1.37 (21-Mar-2005)
- e2fsck 1.37 (21-Mar-2005)
- Linux second 2.6.12.2 #7 Sun Jul 3 01:49:46 CEST 2005 i686 GNU/Linux
