Hey LawDoc, I have a 500gig WD for Time Machine backup and a 1TB WD for regular data storage. Immediately after Snow install I didn’t have either one.
The 500 gig is on USB and the 1TB is daisy chained FW800.
I unplugged both and then reconnected and rebooted. No problems since.
I was thinking SL didn’t like the 1TB drive since it’s so big...but no probs since.
thanks!
