The HDAPM trick seems to have worked, these are my new SMART utility results:
The load cycle hasn't changed since I used HDAPM, so I'm happy about that. The temperature seems to be constantly at 33 - 35 now (i'm just using firefox and mail), is this still ok?
Is there any reason why this happens to only some scorpio blue disks? should i try to get a replacement? and if so, how would i argue my case?
thanks for all the help guys, i'd be pretty lost without you
"The HDAPM trick seems to have worked" is a little vague, did the HDAPM utility solve the sluggish problems?
Temps in the 30-40 degree range are low, "not to worry"
Why does this issue hit some disks? That's a complex issue, with many factors, some think it is the drive cables, some the firmware, some think it is a compatibility issue with the drive firmware, etc, etc ....
no matter what it is it has hit many people in many forms. If you get your machine working right with that disk and HDAPM stick with it, you may have other issues with a different disk. If you are adventurous you can try it...
Returning that disk is a waste of time, INMO, just get a cheap external USB case and use it for backup if you decide to try another brand HD.
tomshardware HP has a list of HD performance, with the Hitachi #1, Seagate Mementos #2 and the WD Scorpio somewhat down the list.
Glad to hear you got the HD working but try to report on how it helped so others can benefit from your experience.
