C1537/a C1554/a unable to write DDS3
So they loose the middleware printers to Brother, Notebooks and Streamer to Sony and so on.
Be aware HP and excuse my poor English.

Re: C1537/a C1554/a unable to write DDS3
I have seen a lot of drives in my live, also drives with five and more years and really finished once. Of course if you do so something, you will do it only on Ready Trade or OEM once.
So it would be very funny, if there will be the news some day, that someone found the l&tt script to reset this counter. I???m waiting for this.

There is no "firmware counter" or any other similar contrived system in a HP DAT drive to wear your drive out, thus forcing you to buy new ones.
Not knowing how you use your drives, I can't really comment on whether they are genuinely at fault. You also do not describe the symtpoms of the 'failure'.

It sounds like you have already tried the recalibration scripts
http://www.hp.com/cposupport/information_storage/support_doc/lpg50236.html
Usually, you first avenue of getting help should be to contact one of our hp call centres. These people should help you, whether or not your drive is warranty (although your drive will need to be in warranty to make an exchange):

Perhaps the examinations of the next weeks will show that. In the moment we believe that there are modifications of algorithms that controls the tape-positioning.

The drives were used 5 days a week by a amount ~ 5GB since the middle of 2000.
They were cleaned every 2-4 weeks using a DDS-CleaningCartridge.

Re: C1537/a C1554/a unable to write DDS3
This is one of the reasons, why you should get support contracts for your hardware.
You pay less on a suport contract than for new hardware.
By the way.
We have used DDS drives for backups for several years. The drives usually failed after
18-20 months. this is not unusual according to the high usage of these drives.

surestore_dat_24_tape_drive.pdf they say 300.000 or 200.000 hours at 12% duty cycle.
If I believe that, my drives should work for the next five years.

yes well.
Good luck with finding the non-existant "firmware counter" - while you are about it maybe you could locate the Holy Grail and the Ark of the Covenant !

Re: C1537/a C1554/a unable to write DDS3
There could be any number of reasons why the drives have failed, again, it is best to call HP support and have them analyse the error codes and determine your best course of action.
Some things to consider are:
- you have been cleaning the drives, have you been replacing the cleaning tapes? After 50 uses the cleaning tapes expire.
- are you over using the media you use to back up your data, has this worn out?
- are you keeping your media (when not in the drive) in a suitable environment.
- is the drive in a suitable environment (i.e. an office environment, away from excessive contamination etc.).
- what is the duty cycle of the drive, if the transfer rate is low for your 5GB of data the drive could be doing excessive hours and repositioning.
All of these things can be considered, and, as you can imagine, a number of these areas could potentially cause 2 drives to fail together (i.e. if your cleaning tapes expired).
Call HP support and have them advise you.
