Hey All,
I'm having the same issue as others that i have 8 total drives - 3 Are new drives with write caching enabled, 5 are previously used in a windows adaptec controller environment that wont enable write caching. I've tried numerous hdparm ways and the script that was provided above, but i'm still unable to get it to set to be enabled at all.
Just keeps showing
setting drive write-caching to 1 (on)
write-caching = 0 (off)
Then i hdparm -W on the drive and shows
write-caching = 0 (off)
I've also contacted WD Support as these are WD Red/White drives and they're unable to assist as they only support Windows/MacOS, so not entirely sure as to what to do/try now. Any assistance would be greatly appreciated on this.
