I had a problem a while back basically I started to lose drives hard drives windows explorer. Often it would give me the message that basically said format before use. Or it would just be unavailable. In command line it said drive not available (simular to when you try and access a removable drive and no drive is present).
I reboot the system (power off/on) and the drives come back online.
My computer consisted of WD 1TB black, WD1.5TB Green and another 500 gig drive
In a process of elimination I replaced the drives, cables, power supply motherboard.
New PC, new drives : 2 x 1 TB WD Blue + the old 1.5 TB WD Green
I finaly got the system semi stable and it started to happen again. This time a new 1TB Blue D drive falls ofline.
It is like the drive goes to a hibernate mode. I have set up power mode to never shut the hard drives down.
I am begining to think I have missed a software thing in windows as almost all the hardware is new.
Can anyone help me.
