It's not an ideal solution, and your problem may not be hardware failure, but it would be a good idea to rule that out before pursuing any other diagnostic methodologies. That's my thoughts. It about has to be hardware at this point. The other drive on the same cable is doing fine. It's not like I picked the wrong driver in the kernel, the other drive would be slow to if that was the case. The drive is pretty old to. Of course, it's not as old as the others but it is a different brand too. Thinking about getting a new 1Tb drive. ;-) Dale :-) :-)

Maybe ZCAV will help? http://www.coker.com.au/bonnie++/zcav/ >From the bonnie++ home page: "The ZCAV program which I initially released as a separate package tests the performance of different zones of a hard drive. It does not write any data (so you can use it on full file systems). It can show why comparing the speed of Windows at the start of a hard drive to Linux at the end of the hard drive (typical dual-boot scenario) isn't a valid comparison." hth, James

I got some strange results when I tested them Try bonnie and bonnie++ both in portage. hth, James I don't think bonnie will help on this. I have not used it but I don't think testing it is going to fix the issue. I already know it is slow, I just don't know why it is slow. The other two drives on here are fast including the other drive on the exact same cable. Makes me wonder what is going on. If you know of a way bonnie will help, let me know. I don't have it installed and don't really know much about it except that it does tests. Dale :-) :-)
