Western Digital "Green" hard drives - issue

[Rico]

Just wondering if anyone here has used these "Green Drives" from WD?  I bought one a few months back and it's been giving me some I/O errors in Vista.  When I run checks on the drive, all is good.  Now these drives are "green" because they power down after a time when not accessed.  But for some reason mine seems to have trouble 'waking back up.'  I don't use this drive a lot, it's more for backup and extra storage, but it is annoying.  I can get it to access again but it takes a PC reboot.  I may write Western Digital and try and get a replacement.  Thoughts?

I read some not so great comments about them on...I want to say Newegg.com.  Me personally, I'll never touch them...you're not being that green by using these, but hey, I won't say its the worst thing in the world.  More power conservation the better.
