From where i can get the drivers of HP DAT72 tape drive?

Kindly update the firmware of tapedrive and library

Because the DAT72 can copy 72GB with 2:1 compressed, and it's native capability is 36GB in the most. So you can try to copy less than 30GB data to it or try to enable the drive's compress mode.

Hi,

Perform the cleaning action using a new cleaning tape. It is not recommended to clean the tape over and over again, if the cleaning light is still ON. Contact the vendor and get it sorted out.

Please coem back and rate the solution if this turns to be helpful for you.
Thnx

Clean the drive 5 times in a row with a non expired cleaning cartridge

Try to plug the tape drive in an exclusive SCSI controller

Make sure there are no pending jobs on the drive, if the drive is expecting a tape and gets a cleaning tape it will spit it out. Also, has the cleaning tape been used a lot? They have a limited life cycle and if they have exceeded their max uses they may not work.

try a different Cleaner tape, they dont last forever..

here select your OS and then the latest firmware

Tape drives do need cleaning frequently and the 'auto clean' facility may not be enough. The problem is the continuous shedding of oxide needs cleaning right off and the auto system may not be enough. What you need is a back-up Drive. and the out of service drive needs physically stripping down to clean all off using a soft brush and where appropriate coproponal alcohol
