I have 3 physical drives in my desktop, 1 for the operating system, and 2 for data. However, upon returning from standby, the 2 data drives no longer appear under Windows Explorer. They're not visible under Disk Management either.

Drives are SATA running in AHCI mode. OS is Windows 7 x64 Ultimate.

Anyone have any idea as to why I'm losing two of my drives afer a return from extended standby? (~8 hours)

Wow! That's .... bizarre. Are you up-to-date on your BIOS? – tcv Jan 29 '10 at 16:48
do your drives show up if you run "scan for hardware changes" from device manager? – quack quixote Jan 29 '10 at 17:12
Yes, November 2009 BIOS version. – Ryan Kearney Feb 3 '10 at 1:54
No, they do not. Only after a restart do they show up. – Ryan Kearney Feb 3 '10 at 12:06

Reformatted, problem solved.
