C1537A (12/24 DAT) and DDS3...

Hi,

I am running Seagate backup exec 8 on NT4. I have a Compaq labled HP C1537A drive.
Backupexec can write to and read from DDS2 without a problem. When I insert DDS3, I get an unrecognizable media error and am prompted to erase the tape. If I try erase, backupexec ejects the tape and alerts me to insert another tape.

I have replaced the DAT drive.
NT sees the device as a C1537A. Backup Exec detects the device as a 12/24 drive. What could the problem be? The drive has 8 dipswitches (all are in the ON position).

Anybody who can offer assistance... please help!

Thanks

Quote from HP

"Many Drives Use an Identification String of 'C1537A' - Refer to the Actual Model Number to Obtain Parts"

So you probably do not have a C1537A, just something that identified itself as a C1537A.

I commend the following URL to you

The drive is definately a C1537A, 12/24GB drive. Of this I have been assured by Compaq.

I have left the dispwitches alone as this is how the drives were shipped by Compaq to me. Dipswitch 3 (Media Recognition System) is in the ON position which I believe disables the Media Recognition System. Should I switch dipswitch 3 off?

If you're absolutely sure that the drive is a real 24/12 drive, there are a number of things you could check. First of all check Seagate's site for any similar user problems or software upgrades. The error you get is what the application thinks it is wrong which might not be the real problem. What I mean is that the SCSI interface returns an error code and the application interprets it. Check also the tape drivers (http://www.hp.com/cposupport/information_storage/software/dds_nt40.exe.html)
and most surely your SCSI card drivers. We had some problems in the past with such a device and the problems were solved by upgrading the drivers from Adaptec. From what you say it shouldn't be a hardware problem. Good luck.
