I have given up of Western Digital HDD’s I’ve bought a WD3000JB PATA drive and it produced a high-frequency whistle noise while reading/writing, but not in idle mode. That tone was horrible, I couldn’t stand it even inside a closed enclosure with fan noise behind. I had to return it to store and ask for a refund. They said the noise was normal for these Caviar SE drives
The drive with FDB motor creates much noise than my old 120GB WD drive
Now I want to choose between Maxtor and Hitachi. I have an old 20GB Maxtor HDD and it never failed, although it has that “scratching” like noise, but that noise I can stand. I don’t know about Hitachi but from the mp3’s I’ve heard with the acoustic noise, it seems to have also some whistle noise too.
I don’t plan to buy Seagate HDD’s, but Samsung is a big possibility too (SP2514N model).
