Noooo, this is a 250 GB drive with tons of data (mostly bigger files) on it.

Slice names are version dependent. In major releases the names have changed a bit. There are a few recovery tools in the ports. You can try those and see if they find any usable data. Since it is only 24MB hopefully any data loss is minimal. -Derek At 05:08 PM 2/22/2007, Marty Landman wrote: Thanks Derek, I tried deleting and recreating the one slice on that drive in sysinstall, also rewriting the boot label.

You can easily try it in sysinstall. -Derek At 04:19 PM 2/22/2007, Marty Landman wrote: I wrote about this problem before, still working on recovery. After a power outage I lost my primary slave hd, a 250MB Maxtor.

Have been looking for pertinant information to learn how to pick apart whatever's keeping my drive for being mountable and fix manually but either don't know what to look for or haven't found the right explanation yet. For instance, is it possible if I somehow 'eliminated' blocks 129 through 144 that the volume would then mount for me? Any help would be appreciated.
