DDS4 Tape Drive Functions (Modes)

This is not exactly a linux question but it is a Compaq DDS4 Tape Drive made by Sony attached to a linux server.

Here's the deal, yesterday I replaced this tape drive with the exact same model, but the new drive was having trouble ejecting the tape. Because I was out of ideas on how to get the tape out of the drive, I held in the eject button on the drive for about 5 seconds, then the tape ejected. After the tape ejected one of the lights kept blinking. I thought it was asking for a cleaning tape so I tried to insert one. It wouldn't go in. I held the eject button in for 5 seconds again and it stopped blinking waiting for a tape.

This appears to be some type of feature that I'm not familiar with. Does anyone with a Sony or Compaq DDS4 tape drive have an idea as to what this mode is for. I've read on other brand drives that this is possibly a cleaning mode where you have use a swab to clean the heads and rollers, but I didn't see any movement on the inside of the drive. Any help would be appreciated.

Post dds drives

please dont put any swabs into the mechanism.
dds drives are like many drives today based on videotape technology, and this means they have a helical scan head.
even video recorder heads which are bigger, are very fragile and easily damed. computer tape drives are very much more precise and suseptaple to damage.
only use a cleaning tape.
my dds drive also exhibits similar behaviour, but i canot give you reasons
just keep those swabs out of the drive
regards peter

Well as an added ???, I can't get the drive to repeat this behavior. It appears to work only when a tape is actually stuck in the drive.

Better late than never. Found an "unload" spindle underneath the tape drive that you can spin with a small phillips screwdriver. Worked for me trying to remove a snapped tape.
