Ultrium 960 ext. Drive SOOOOOO slow.

[Yiannis Valkaniotis]

Hi! I Use the Ultrium 690 external drive. I connect it through the Adaptec 19160.
It is correctly recognised by windows but when i set it to backup about 300GB with no compression it asks for almost 4 days!!!
I believe that there is something wrong with the speed!!! I believe it is not the drives problem but something to the connection or the setup.

Am i missing any important setup issues?
Can someone please help???

Use the free HP LTT (Library and Tape Tools)
It contains beside many fetures and tool a performance analysis function which will show your bottleneck(s) (Network, Tape, Disk, OS Filesystem ...)

See
http://h18006.www1.hp.com/products/storageworks/ltt/index.html?jumpid=reg_R1002_USEN

Download the tool from:

Hi,

problems like this are often due to a bad or missing terminator. The SCSI bus will shift down to the slowest speed ever possible or it will just fail to work.

Please check the cable connection and termination first, then try to run LTT as mentioned.

well, all i had to do was to buy and install a 320 SCSI controller and use the cable that came with the drive. Now i have 80 & sometimes 93 MB/sec speed.

Thank you all!!!
