<< There are numerous issues right now with the higher capacity WD drives. >>
What issues? I'll tell you the issues i had.
Purchased a 80GB WD 7200 HD in September of last year. In November it went belly up. Clicking sounds, inability to access the HD, and it started disconnecting itself from Win2k. They NEVER asked me to run any HD test, i told them the symptoms and they just gave me an RMA. I lost a good bit of data because it's hard to backup 40-50GB of info, but i had most of the stuff i needed backed up.
So i get my HD back in Dec. and everything is great! It is now March 5th (two days ago), drive starts clicking and i know immediately what is happening. I start backing up whatever i can and the drive starts disconnecting itself, clicking, inability to read the HD (errors out). I got some of it, but i think i lost more this time than last...lol. So i call WD and i tell them the symptoms again and they immediately give me an RMA. The guy NEVER asked me (again) to run any HD utilities or checkers. I asked the guy if these drives have known problems because of the two i had died with the same symptoms and only after a few months each! They denyed it and said it was really odd that i had two of them go bad. But they never asked any questions or anything.
I had only one previous HD problem and that was with a Quantum Atlas II Ultra 160, but that turned out to be a drive problem with my Adaptec 29160 card and the HD. But the 4 times i called Quantum they kept asking me to run HD utilities and such. It's kinda funny that everytime i called them, they asked me to, and the 2 times i called WD - they never asked and acted like it was a known problem.
I thought maybe it was a heat issue, till i realize i have an 80mm Sunon fan blowing right on it and the drive never got hot. I've got one of those chieftec Antec type cases, that has a fan in the HD cage. Plus the other fan in the front and the two in the back..the case stays VERY cool, so it's obviously a HD problem, or i just got two bum drives???
Time will tell though! I have two new 80GB 7200 WD HD's on their way to my house as a nice replacement for my problems (bitching works!). I will see if either one of these HD's have problems in the next few months and let you guys know. A 100% fail rate sucks!!!
