The answer is: It it not possible. :-) You cannot mount a slice. Given the BSD terminology: A slice _has_ to contain partitions. You cannot format a slice, you can only format partitions. A formatted partition carries a UFS file system. (However, it's possible to omit the slice, and partition the whole disk instead, this is called "dedicated mode"). A third method is formatting the whole disk ("the 'c' device"), in that case the 'c' is omitted. The _only_ time you can mount a slice is when it is used in its common meaning, being a "DOS primary partition"; in this case, a FAT or NTFS file system will be placed directly into a slice, as those do not support any (BSD-style) partitioning. /dev/ad0 -> the disk /dev/ad0s1 -> 1st slice /dev/ad0s1a -> 1st partition on 1st slice THIS is something you can mount. -or- /dev/ad0a -> 1st partition on disk ("dedicated") THIS can also be mounted. -or- /dev/ad0 -> the whole disk (equals /dev/ad0c) Even THIS can be mounted. In case I'm misunderstanding your question, could you alter the expression? -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
