Hi, I have a Seagate ST336607LW scsi disc in my system, its only 34GB big and was intended to be used as the system drive.
I'm experiencing performance loss in a very wierd situation; Copying large files, say a cd image or a movie, and where the scsi disc is both the source and destination I get speeds of about 3-5Mb/s whereas I use any other drive in my system as either the source or destination I get between 30-70Mb/s depending on which drive I use.
I'm using an adaptec 19160 card with this drive, and I've checked and rechecked bios on card and the jumpers on the drive and the termination also so the drive should operate in its fastest mode. And it does except for the situation above. Very annoying. Using it as a system drive is not an option now. Could this still be a termination quality problem or some bus mastering issue?
Please help!
Another thing, which might be a clue, with the file manager I use (Dopus) I am able to pause a copy operation of a large file and after doing so and then resuming the copy I get a brief burst of speed up to where it is supposed to be, but then suddenly it drops again down to 5Mb/s. Seems to me like its a buffer overflow problem. Oh btw, I talked to seagate support, had the drive replaced but the problem persists even with the new drive.
(Also updated my ASPI drives to the latest I found)
