Thank you but some
of the fs are not Unix filesystems but MS DOS and NTFS
does dump work with non-unix fs'es?
if i want to dump ALL the partitions into 1 file per
disk, without mounting each disk? is this possible?
as it is now, i am NOT mounting the disk, and i have
tried listing the partitions in many ways, /dev/ad3s1,
/dev/ad3s1a, /dev/rad3s1e etc ..
what would be correct syntax? if this is not?
thanx
