Make sure you do a complete power off of everything first before you do anything to your SCSI devices. Terminate both ends of the SCSI bus. The controller card is one end and you have it auto-terminated. You must terminate the other end of your SCSI cable either on the last device or beyond the last device at the end of the SCSI cable opposite the SCSI controller. Put your power terminator back on the end of the SCSI cable, leave your devices unterminated. Are these internal or external SCSI devices; controller, tape drives, etc? Are all devices on the same SCSI bus? Stan Donald Polak wrote:

Did you enable writing on the SCSI devices /dev/sgx and /dev/sgy (sg1 and sg2 I suppose with your configuration) ? Catimimi.

Just a thought have you tried different tapes and brands of tapes. In the past I have had problems with tapes that give you similiar results to the problem you posted where they refuse to record. This is especially true if they have been used in another tape drive for some reason. It appears to be more to do with the tape than the drive, as I quite often use tape to transfer data between work and home. -- Regards, Graham Smith ---------------------------------------------------------
They are all new or used in that drive before, but under a different format. I'll try the one tape that worked before to see what it says. Don Graham Smith wrote:

(ok, two) 1) The original problem you reported is not unusual for a device that has written off the end of the tape. 2) I use bru for tape backup ( www.tollisgroup.com ) and they have it noted on their website that kernel 2.4.19 misses the EOT indicator on some scsi devices and its not the hardware fault.

I will look into it further. It could be that the system is missing the EOT. The Python 24GB goes back and forth, back and forth, but data is never sent to it. The SCSI card doesn't even light up. I will look at BRU, and keep the drive aside, maybe 8.2 will be compatible with it. Thanx again! Don John Andersen wrote:

You _may_ have a separate terminator for the device end of your SCSI cable. If you _do not_ have a separate terminator then you _must_ have your tape device terminated at the end of your SCSI cable. Your SCSI controller will also terminate it's end of the SCSI cable. If you _do_ have a separate terminator make sure that is at the end of your SCSI cable past the last device and leave your tape drive unterminated. I misunderstood what you meant by "Power Term" and "Termination" in your first post. You may need to enable "Power Term" on your SCSI tape drive but leave "Termination" disabled. Starting in the Ultra Wide SCSI days, termination became even more critical due to shortened cable lengths and noise on the SCSI cables. Providing power to the termination lines helped make the SCSI signals more reliable from end-to-end. Termination is absolutely required at both ends of a SCSI bus. Stan Donald Polak wrote:
