Re: Wanted: Fujitsu 2443/2444 info

Tim,
I've doug out my Fujitsu documentation and found out how to do it. Use 
test 97 in parameter P1 is the transfer speed encoded. Use test 94 to 
save settings in NVRAM, if you wish. A step to step procedure follows:

- turn the drive offline and unload the tape (necessary step!)
- press TEST and START simultaniesly. TEST and HOST LEDs should turn on
- press UNLOAD until the 7 segment display reads 97
- press TEST and DENSITY SELECT simultaniesly, the display should read P0
- press RESET, the display shows your current transfer rate setting. the 
  codes are:     00     1 MB/s
                 01   888 kB/s
                 02   800 kB/s
                 03   727 kB/s
                 04   666 kB/s
                 05   615 kB/s
                 06   571 kB/s
                 07   533 kB/s
                 08   500 kB/s
                 09   470 kB/s
                 0A   400 kB/s
                 0B   320 kB/s
                 0C   250 kB/s
                 0D   200 kB/s
                 0E   160 kB/s
                 0F    60 kB/s
- press START or UNLOAD until you get your desired transfer speed
- press TEST the display should change P1
- press RESET
- repeat these two steps, toggeling through P2 to P7, until the display
  read 00
- press UNLOAD until the display reads 94, selecting test 94
- press TEST and DENSITY SELECT simultaniesly, to execute test 94        
- press TEST, to leave test-mode

After that you should have your tape drive permanently at a new transfer 
speed.

reards,
Dietmar
