Subject: AFFS oops.
Date: Sun, 20 Jan 2002 14:28:11 +0000 [thread overview]
Message-ID: <20020120142811.A22052@suse.de> (raw)
It's a boring Sunday afternoon, so I decided to do some destruction testing
on unusual filesystems. First on the list is AFFS.
I mounted a 900k AFFS floppy disk image via loopback, and ran fsx on it.
It dies instantly, before fsx gets to do any of its usual fun.
