SCSI Hard Drive Problem

SCSI Hard Drive Problem. Is it dead?

I just bought a 2nd hand SCSI setup, consisting of an Adaptec 19160 PCI controller (Ultra SCSI 3, so should be 160MB/s), a Quantum Atlas 10K 18.2GB Drive and a round 68pin SCSI cable with terminator.
I have set it all up, however there seems to be a problem with the drive. When I test it using HDTach or HDTune, it gets VERY poor results. At the same time, it makes very loud noises (kinda like a mobile phone if it were vibrating ontop of your pc case ) during some of the tests. I can access it fine, and Windows Scan Disk says it has no bad sectors.
I know the PCI Bus could be a limiting factor, but could it limit it that much, or is it a dodgy drive, or is there some setting/setup issue somewhere that I'm missing? The only other thing I have on the PCI Bus is my sound card.

Here is the screen shot from HDTach:

Thanks in advance.

Not sure what is going on there mate, have you done a health scan on the drive to check for bad sectors?

No bad sectors, and HDTune Health Check says OK at the bottom, but has no details in the window, such as Seek error rate e.t.c. which are present for all my other drives.

I retested the drive and got an average read of 33MB/s. I still think thats a bit slow though, but could it be the max I'm going to get out of it?
