Hard drive on networked computer "disappeared"...any suggestions?

[HXGuy]

My wife and I work from home and have our computers networked so we can access files from each other's machine.

On her computer, she has three hard drives, labeled Hard Drive, Storage Drive One and Storage Drive Two.

Up until about a week ago, I was able to log into her computer from mine and access all drives. For some reason, Storage Drive One has disappeared off the list. The settings were not changes and looking at the Permissions for that drive, they are identical to the permissions for the drives that I can see/access. She still sees the drive just fine and everything is working as normal on her end.

Any ideas? I'm at a total loss here.

What Macs and Mac OS X versions are involved?

Im on a new iMac running Snow Leopard, my wife is on a G5 running Leopard. The thing is, it's been working for the last few months just fine but then one day all of a sudden I can't see that just one drive anymore...all the other drives on her computer I can see.
