Becky, I've had similar experience. We send about 100 GB / day to our 3583 (4 drives). As far as I know no drive has ever cleaned itself. The library has been in service since last October. But in general, drive cleanings are rare on our system. We have a mix of 3570, LTO, and DLT media and I see 1-2 drive cleaning events per month on the average. That's across a total of 16 drives.
And we too have had two LTO drives replaced because of tapes stuck in them. And I mean SERIOUSLY stuck! The local CE disassembled the first drive that jammed and still couldn't remove the tape!

I have had the same concern. I also have had two drives replaced because tapes were stuck. It is an interesting theory...instead of fixing the drive when a tape is stuck they just replace it. Definitely different from the 3590s.

Got to admit I've been wondering about this myself. I've a 3584 library with 10 LTO drives that has been in service since September of last year. I've got three cleaning tapes in the library, I move 130 GB of data per day -- and I haven't seen a cleaning tape used yet. I know the drives and tapes are supposed to be self-cleaning, but this is almost to good to be true. OTOH, I haven't run into any errors that indicate dirty drives. . .
