problems with old SATA drives
A client wanted a larger HDD. The MB had both IDE and SATA and looking at the prices of each, the SATA was 1/2 the price
I purchased a 320gb and cloned his old one over (I found the jumper on the drive) but it seemed suddenly very slow
I did some benchmarks on the old 5400 rpm IDE drive and the new 7200rpm SATA and the SATA was crap
I came to the conclusion that the MoBo was very early generation SATA and just didn’t like the new one, even with the jumper changed
I had to bite the bullet and purchase a 320gb IDE (cost? Ouch) LOL
The performance now was good
It was only last week (6 months later) that I found a home for the 320gb Sata and it was fine
Interestingly the drive had a 3 yr guarantee while current stock is only 2 years and cost double what I paid (due to the Thailand floods) so the client was still on the right side of the deal
I actually had exactly the same problem and it drove me insane trying to work out the problem
