Re: DLT8000 Flashing LEDs
If the drive had a tape half spooled down the tape, and would not retention and rewind the tape after being power-cycled, it most likely indicates that it is having hard servo problems (or it's possible that the tape had packing problems, and the drive could not maintain correct tension).
Can you run HP L&TT and generate a support ticket? I'd like to see what it is returning for SCSI Test Unit Ready status, and also what the drive event/error logs contain. You can just post the support ticket here (.ltt file).

If you can tell me how I would gladly do it.

Re: DLT8000 Flashing LEDs
1) install LTT from www.hp.com/support/tapetools
2) Run the program, and select the drive from the "by product" tab
3) Click on the support tool
4) Click on save support ticket to file
5) Post the resultant .ltt file

Re: DLT8000 Flashing LEDs
---
Vendor ID : COMPAQ, Product ID : DLT8000
Firmware Revision : V080
Controller Serial # : PKB14P0188
Drive Personality : CPQ2 (0x0C02) [Compaq branded]
SCSI Test Unit Ready returns a check condition
- SCSI Info : 0x02 0x0403 (Logical Device: device does not report ready)
---
This says "Unit not ready, manual intervention required. No tape present or mechanical failure has occurred."
And in the drive error log we see:
---
Event # 12 - Packet # 12 - BugCheck Error: A209 [V80-0 12-SEP-2001]
PC= 000741E2 SR= 3000 Cntxt= SCSI 000:18:48.990 POH/PC= 10060/8
Event # 13 - Packet # 13 - BugCheck Error: A209 [V80-0 12-SEP-2001]
PC= 000741E2 SR= 3000 Cntxt= SCSI 000:18:48.980 POH/PC= 10075/10
---
These happened 44 and 69 hours back. An A209 bugcheck is a servo timeout on an operation. It is usually either a dropped leader or a whir (where the gears don't mesh with the tape hub).
Here's a doc on checking for a dropped leader:
http://h20015.www2.hp.com/hub_search/document.jhtml?lc=en&docName=lpg50027
You can look into the mouth of the drive and should see the drive leader portion attached to a little arm. If you don't, the leader is most likely wound up in the drive.
If your drive is out of warranty, here's how to reattach it:

If it doesn't have a dropped leader, it most likely has other mechanical/electical problems.

Re: DLT8000 Flashing LEDs
Looks like it does. I reset the leader, it was not on very well from my last reset. The drive looked good, then I put in my cleaning cartdrige (so I would not risk any backup data) and the same error resulted. I took the drive out and looks like it is partially on the take up spool. Here is the error file from this.

Re: DLT8000 Flashing LEDs
I've not seen that particular sub error code before, so I can't offer any advice.
If you are getting repeat dropped leaders or tape unspooling (e.g. all the tape ends up in the drive), one common cause is a clogged BOT/EOT sensor. This is an optical sensor in the middle of the tape path that watches for the BOT/EOT holes in the tape. The receiver part of the sensor looks through a little hole in the plastic leader guide that can get clogged up with debris (e.g. shed oxide from the tape) over time.
If your drive is out of warranty, and you're having that problem, you can try cleaning it out with some compressed air (before reattaching the leader).

Re: DLT8000 Flashing LEDs
After removing the tape, removed the power and checking the drive I noticed that when you manually turn the reel there is too much resistance. Only replacing the drive resolved the problem. In my opinion this error can occur when: the drive firmware is below V86 and the backup software is set that it has to do a eject after backup.
There is an issue that if you do an eject after backup, you have to remove the tape as soon as possible. If you don't do this, like most customers, there is a possibility to damage the drive. V86 prevents this, after an eject you have a short periode of time to remove the tape. If not the drive will remount the tape.

Re: DLT8000 Flashing LEDs
I wouldn't mind looking at the drive error logs. Can you generate an HP LTT support ticket and post it here?
