Your drive has failed. LaCie can likely replace it under warranty.

Very bizarre. The drive doesn't appear on my desktop, but Disk Utility "sees" it, and seems to do a repair when I run First Aid, returning an "Operation successful" window. (I took a screenshot—is there a way to post it?).

PS: The drive is very, very old (pre-iMac...way out of warranty).
