SolutionL&TT 3.5 should still be available for use with that library.

Re: HP Ultrium 1-SCSI Drive and 1/9 C7145 Autoloader firmware
Is that an LTO1 LVD drive? (Ultrium 230 LVD)
I think I can find the FW files for you:
This should be the file for the autoloader:
ftp://ftp.hp.com/pub/information_storage/software/ltt/firmware/LTT_C7145_2710.frm
And most likely, this the one for the drive:
ftp://ftp.hp.com/pub/information_storage/software/ltt/firmware/LTT_Ultrium_1-SCSI_E3BR_OEM2.frm

Re: HP Ultrium 1-SCSI Drive and 1/9 C7145 Autoloader firmware
I am using Linux versions but dont have any restriction on outbound packets to the LAN from the server on my firewall.
I will try the 3.x L&TT. Is it likley to tell me anything different in diagnosing my faults?
At present both units are failing the Drive Assessment test.
- Amount of data required~R test option : Default
- Iteration number: 1 of 1
- Overall Margin: Warning (1.4 GB written)
- Wrap 4 Margin: Warning
but dont know how to interpret what this means.
I did see another failed test saying
"margin (<-100%)"
but that is equally cryptic.
I am a little suspicious. Although one of the units is giving me media related problems (hence the reason for running L&TT) the other is a standby device which sees very little service - so I wouldnt expect it to be showing the same error.
Can anyone offer any help?
Dave

Re: HP Ultrium 1-SCSI Drive and 1/9 C7145 Autoloader firmware
The tape has built in margin and the drive does a read after write so it can measure the signal it wrote. If the signal isn't as high as it wants then it writes the block again. When all of the extra tape (margin) was used up in the re-write process then L&TT reports the < 100% margin meaning that all of the margin has been used up and the useful capacity of the tape will go down.
Frequently the drives will still perform well long after the tape is worn enough or the head is worn enough that all the margin gets used up as the minimum allowed write quality is quite high.

Re: HP Ultrium 1-SCSI Drive and 1/9 C7145 Autoloader firmware
It was <-100% not <100% that was reported which was slightly misleading. Maybe that was purely presentational license by the software author!
Where I am struggling is that both drives report failed (with "The drive is no longer recommended for use") on the Drive Assessment test and on other tests appear to report similar results between drives albeit I seem to get differing results each time I try.
However in practice one of them is reasonably OK the other one is unreliable for backup. The main failure are rewrite and fast forward filemark errors reported by my linux based backup system.
Beyond the acknowledged uncertainty due to the failures which prevent the other test results from being validated the drives seem to indicate plenty of head life etc and typically my media has only used up a moderate % of its various parameter cycles
How do I tell what is really wrong?
I need to determine whether my backup solution is worth repairing (again) or whether to call it quits and reinvest in something like a removable disk solution.
As I mentioned before I am a one man organization I cant afford to waste my limited resources!
Thanks
Dave

I can only find HPUX or Windows versions still available on HP's web site.
