When I used my Momentus XT on my desktop I had no issues whatsoever. I had problems when I installed it together with other drives in another computer I have for storage, the Momentus would not speed down and the voltages for this desktop's PSU became very scary. Since then I replaced the momentus with a regular drive, and when I got access to the SD25 I reinstalled it in the storage array and my issues were solved. Since I already had another drive I placed it back at my personal desktop as the OS drive, and everything is rock solid, even tho, in this computer, it never presented any issues.
My guess is that most of the problems happened in notebooks, these are more prone to power shortage, so the momentus not speeding down caused a lot of headaches to users. Most other people I've noticed that do complain about it are people with Macs, they are in the ugly side of situation. Honestly, I didn't see anyone complaining about the drive when using it in a desktop, and the reviewers out there in the web are always enthusiastic about the drive, so I guess the answer for the OP's question is: Yes, a lot of people did not encounter any problems with the drive, and for that very reason they don't need to complain here at the forums.
