An internal firmware update exists for certain HP DAT. I have no idea
about what it does, nore where to get it from. It's actually a DAT which
you insert in your DAT DRIVE and it automatically updates if needed. I
haven't trid it, only heard about.
There is also an utility called DATTEST.EXE or DATAUDIT.EXE (MSDOS)
which can tell you things about yout dat drive. (
HERE IS THE README.TXT :
DATTEST AUDIT 3.0 User Guide 18/9/96
Dattest express is a diagnostic utility for HP DDS products. It
supports the following drives:
HP35470, HP35480, C1534, C1536, C1533, C1553, C1537, C1557
Note that the inquiry string is not used to determine the type of drive, so
that OEM drives with different inquiry strings can be tested.
It runs on DOS 5 or later and requires an ASPI compliant HBA and manager to
be
installed.
Details of the test are given below:
For each HP DDS drive found:
1) Do inquiry, display codename, inquiry string, FW rev and Servo rev
2) Read serial EPROM, if supported, write the raw data to the file serial.res
3) Read EEPROM error log, deode and display any errors
4) Check calibration constants, fail if any constants are not calibrated
5) Ask the user to load a tape. If the device is an autoloader ask the user
firstly to load a full magazine then tape 4 into the drive. Monitor the
tape
loading process, fail if the drive reports an error or the timeout is
exceeded.
6) Read tape log and display a summary.
7) Space to EOD, write a filemark, write 2MB of data, disable compression if
supported, write some more data, the amount being dependant on what sort
of
tape is in the drive: DDS1: 38MB, DDS2: 110MB, DDS3: 220MB. Fail if the
drive
reports an error. Read C1 error counters, display the average of both
channels and an appropriate message.
8) Space back one filemark, read the data and perform data compare. Read C1
error
counters, display the average of both channels and an appropriate message.
9) Ask the user to press the eject button, monitor the tape being unloaded,
fail
if the drive reports an error or if the tape takes too long to unload.
Dattest Express will display a menu when invoked; the menu items are:
1)Quit Test
2)Log test results to file - (dattest.res)
3)Extended testing
4)Standard Test
Option 1 takes the user back to the DOS prompt, option 2 causes the results
of
the test to be appended to the file dattest.res. Option 3 does an extended
test,
using 5 times the amount of data as the standard test. Option 4 is the
default.
