I also had problems with a few (about six or seven IIRC) IBM DeathStar drives, but none failed completely, I was always able to rescue the data from them. When they stopped working, I always got them working again with the DFT software, copied the data off them and then only used them in computers where it would not matter if they failed (like networked Windows PC wich kept all the user data on a fileserver). All except one are still working fine today.
After that I avoided IBM and Hitachi drives for a while, but started using newer Hitachi drives again when I started to use watercooling for HDDs. I have never had any problems with Hitachi drives.
