Hi,

i recently got a very cheap PC from ebay. Its old, but i just want to use it for "experiments" anyway.

It came without a HDD, but i have a few spare ones. After i put one in (Old Maxtor 160GB SATA 1.5GB) and installed Windows 7 on it, i noticed that the noise (i think its the seek noise) coming from the drive was a lot louder than usual.

I ran HDDscan to see what was going on. Thats when i ran into the first problem: I cant get a SMART report from the drive (SMART is enabled in Bios and the drive is definately capable) and the "Icon" is showing a PCI extension card, not a hard drive. It also doesnt give information about stuff like the serial number like it normally does. Anyway, i started a "verify" test. It started out good, constant 60MB/s until it got to around 4%. Then the HDD started getting loud and the values dropped to 2MB/s and below. After that it started constantly changing from good (60MB/s, no noise) to bad. It seems to get (a lot) worse the longer the test runs. In the beginning its only short drops, in the end its constantly bad. I have tried this with different drives, different cables, different SATA ports and even another Power Supply. Its always the same.

But the funny thing is: ALL of these drives are 100% OK and make no problems at all when i run the Test on my main PC.
The Tests are fine aswell when i use a standalone windows XP booted from a CD and run HDDscan in that (on the new PC). The drive Icon actually shows a HDD there and i can click the SMART button (its greyed out when i boot Win7 from the HDD), althoug it just gives me an error when i do so.

What could be the cause of this problem? Am i missing something? The Bios settings seem right (there are no options like AHCI, the board is too old).

Here are the system specs:
Athlon 64 X2
2GB DDR2 800
MSI K9N6GM
