I have 4 hard drives. One is a SSD. Two are Western Digital 1 TB (both WD1002FAEX) internals. And the last, and newest (within the last year) is a Western Digital 4 TB internal (WD4003FZEX).
While I was running Windows 7, I never changed the power settings for them. They’d all go to sleep and wake back up normally.
I’ve been running Windows 10 for a few months now and the 4 TB drive shows up and works fine when i boot up. Since its mainly storing my Steam and iTunes / Media folders, its not always active. When it goes to sleep though, it never wakes up. It’ll even unmount. Windows 10 becomes convinced it doesn’t exist. The other two 1 TB drives continue to sleep and wake normally. I have to reboot to get the 4 TB going again.
When it’s powered it works fine. Reads/Writes, data integrity tests check out. Its not throwing out any SMART errors and the WD Diagnotics utility couldn’t find any problems.
Any ideas what’s going on? Does it sound like a bad drive? Something with Windows 10? Thanks in advance!
