HP Ultrium Lto4 tape drive

[0sbourn]

Just got this Lto4 tape drive and its connected to an adaptec ultrawide 320 scsi card. With a new IBM Lto4 tape installed the drive is continually shoe shing. I have tested the drive using the HPE Library and Tape Tools and it appears to be ok. This drive is immacualte and has done little or no work. I have used every block size but no difference. The Lto3  I previously had  whizzed along and this is why I need to find a solution. I will outline my use for the drive and this practice has served me well. I image my system drive with acronis then  using Uranium Backup I backup the image to tape. I also image a lot of other stuff using the method. Has anybody any ideas. . Right now the 320 gig bacvku p is stuck at 1759 MB and going slow shoe shinng something terrible. Is it the fact that the image file is compressed the issue, it never affected the Lto3.

Hi Guys I solved that issue with the LTO4 tape drive. I removed the drive and put the LTO3 back in that was whizzing along but it too was now going slow. I figured the scsi card was common to both so I removed the scsi card from its slot and put it into a different slot. Fired the pc back up and ran a test backup and the LTO3 drive was back to its original speed. Then I tried the LTO4 and its currently backing up at 5.3 GB/min purring like cat. So happy days and cheers to all who replied to my question. I keep the block size to 64 K as it appears that this is the drives recommended size. I dont know enough beyond that as all I use the drive for is to keep a copy of iso images of my drives in case something happens and it did one time so I just dumped the iso onto a drive and let acronis recoved the system.
