hi all, Every time I wake up my system Win7 with 3 HDD: 1. Seagate 1T; 2. Seagate 1T; 3. WD 1.5T green. The WD is gone and Disk Manager doesn't see it anymore. I have to reboot Win7 to get WD 1.5T hdd back every time. This is very annoying. This is HTPC that has to be in stand by S3+S4 (hybrid) for 70% time and I don't want to leave the system on all the time. In bios I have AHCI for SATA drives and Seagate drives works just fine. What's wrong with WD drive? Thanks for the help.
