I'm having trouble with my Ultrium LTO4 drive. Basically this - I can no longer insert a tape. I push the cartridge in until it usually 'takes' and pulls the cartridge down and in, but it just stops, doesn't seem to activate any mechanism. The green light that means AOK stays lit throughout - I'm not seeing any of the error codes listed in the manual.
It's just a single drive, not an autoloader. I'm not really well versed in tape drives - I'm using it to back up video files, not daily backups or something like that and I'm not a sysadmin, though I've had no trouble setting it up and using it for about the last year. I've attached serial number information if that's useful.
At a basic level I'm wondering if it smells like a hardware or software problem - is there an issue with my (Dell 5/e) adapter card or is there a mechanical problem with the tape drive? Is it likely worth fixing a drive like this?
