@ mirh: What happened was that my hard drives were gradually working slower and slower, eventually reaching PIO speed [floppy drive speed]. By this time it was clear something weird was going on and I had begun trying to trouble shoot the system. First I just reset the drives to DMA in Device Manager but after a few days or a week they would gradually ratchet down mode by mode to PIO. It would take a minute to copy a small text file between drives. I ran diagnostics on the drives, ram, cpu, and decided it must be a problem with the motherboard controller and began to source a new board.
About then I started to search for information on symptoms/diagnosis of hard drive issues and stumbled across a thread about Starforce DRM. I instantly realized I had a few of the games under discussion installed so tried the recommended protocol of uninstalling the games and uninstalling SF - which is not unistalled by removing the games... PIO issue solved... Knowing that it wasn't a hardware issue was a relief but since I didn't yet know how many games I still had installed has SF, over the coming month(s) I had to routinely perform the protocol until I eventually got rid of the last SF game. Checking Device Manager for the tell tale signature of SF became a regular part of my maintenance routine.
Around this time one of the PC game mags - possibly PC Gamer - ran an article on SF and described in detail how to completely remove SF. In my case the optical drives functioned okay, or at least better than the hard drives.
The whole episode was very distasteful - lot's of online acrimony and bad blood and counter accusations from Starforce [and other pro DRM factions]about running pirated software etc. Starforce dev's started off by denying the problem existed, then after they had to admit it they slammed gamers by charging that only those running pirated copies of SF games had problems, so basically told everyone to F*@$ off. Infuriating after having been on the verge of rebuilding my system before I knew the real source of the problem.
Eventually I found a complete list of SF infected games and safely removed all that I had. I keep all my Starforce "protected" games stored in a lead clad stainless steel "time capsule" for future generations to experiment with...
