Was running fine. Up for about five days from last restart (sleep instead of shutdown). Purchased 2/1/09. Powered it down to do my weekly cleanings. Tried to power back up and was met with a hung system. Now the drive is not detected by the OS, TechTool 5, Drive Genius, hardware test, disk utility, nothing. Sys info shows an empty SATA bus. Latest firmware. I knew something was up FF hung my machine on shutdown yesterday. Should've picked up on it. Needless to say, i'm pissed. Why? Cause i'll have to crack open my early 2008 MBP to get this sucker out. Thankfully most of the time i'm on these boards its to offer advice, and I practice what I preach, though my backup scheme wasn't nearly as robust as I had hoped for OS failures. It took me about four hours to restore my May 20th backup. I believe this was an isolated issue. Smart status reported fine as I ran tests on the morning of May 28th. Nothing out of the ordinary except the hung system later that day. Still there are some other instances of this occuring to other users, which has me concerned: http://www.daniweb.com/forums/thread192335.html http://www.hardforum.com/showthread.php?p=1034160601 http://forums.anandtech.com/messageview.aspx?catid=83&threadid=2292224 First hard drive in 18 years to fail before i've had a chance to deem it EOL.
