Jack,
Took your advice and ran Fatar Analyze against both 9840A and 9840D HSM
backups which are 100% full. Results follow:
9840A
CHARACTERISTICS OF THE TAPE TO BE ANALYZED
UNIT DEVICE SERIAL MFR CARTRIDGE EMULATING
0536 9840 H00116 STK 20 GB 3490
FINAL TOTALS
FILES READ BLOCKS READ BYTES READ FEET READ TEMP ERRS PERM ERRS
1 4193917 68713136128 **** 0 0
IDRC(COMPACTED) 102065 17909469184 726
9840D
CHARACTERISTICS OF THE TAPE TO BE ANALYZED
UNIT DEVICE SERIAL MFR CARTRIDGE EMULATING
2503 9840D E20677 STK 75 GB 3490
FINAL TOTALS
FILES READ BLOCKS READ BYTES READ FEET READ TEMP ERRS PERM ERRS
1 4193917 68713136128 **** 0 0
IDRC (COMPACTED) 20734 17939517440 189
It would appear both tapes have the same amount of data.
Any ideas?
Thank You,

Subject: Re: HSM utilization of 3490 emulated 9840D tape?
David,
I do believe that you hit it on the head with the 'Unittype(3490)
is specified, which according to the manual nullifies use of the
Capacitymode parameter..' observation. I know that could not get 9840A to
qualify for Capacitymode but I'm not surprise that STK hasn't bellied up
to responding. Since you've mentioned HSM BACKUP tapes, there should be no
doubt about 'take away' being involved. Have you looked at what FATS says
about the tape usage?
Since we are getting away from the STK 'emulation' , we haven't seen any
discrepences.
