I am having a couple of issues after running a PoolRebuild on an NSS

Firstly some directories have dissapeared completely and I cannot
recreate (or restore) them with the same name.
If I do so, I get the following message "Cannot rename new folder:
Cannot read from the source file or disk" I can
however create a new directory with a different name and restore back to

Secondaly, I am having problems with some compressed files that will not
open. The file is listed, I can rename it even, but I cannot open or copy
the file. I get the message "Cannot read from source file or disk"
again. I can though, restore them OK.

OES Netware 6.5sp4

Would anyone have any ideas?

Many Thanks
