Not sure if this belongs into the Data Protector forum. What software are you using to write to the device? Sounds like the hardware compression is not turned on or you just used the wrong device file for backup. Check out HP LTT http://h18000.www1.hp.com/products/storageworks/ltt/qa.html and perform a drive assesment test to see if the drive is ok.

hi its me paint, thanks for replying. i am using the bru to read and write to the tape. you asked me to download HP tape tool and check my drive, I downloaded and installed the hp_ltt414_mac.dmp but i dont know where it is getting installed, so i cant open the file.

My mac os is 10.7.1 (does this os support the software?)

is there any way (command) to identify the tape drive model and firmware etc. for updating.
