HP StorageWorks Ultrium 448 not filling tape

Hello-

I'm having an issue with my HP StorageWorks Ultrium 448 drive not filling the entire tape. I'm only getting around 130GB worth of data on my tapes before I'm asked for a new tape. I'm using Symantec's BackupExec 12 to handle my backups. I don't know if this is a hardware or software issue. This is extremely annoying and expensive to have to change the tapes constantly or add new ones.

Any ideas?

Thank you!

Re: HP StorageWorks Ultrium 448 not filling tape

Maybe you are doing both hardware and software compression, use only hardware compression.

I've checked the compression settings and they are only set to 'hardware'. When I look at the tape info it shows only about 130GB of data is on the tape but the used capacity is 195GB of 195GB. I'm pulling my hair out!

Run LTT compresion test. Send the results if you have good compresion then problem is withing backup exec maybe changing the block size.

When I run L&TT it shows my drive under the "Other Devices" with a red 'X'. The comments reads as "L&TT could not identify the correct NT miniport driver to use to access this device".

Any ideas?

Thank you!!!

Need to stop all backup software services and removable storage before using LTT
