Computer slows to a crawl after sleep mode

My computer slows to a very slow crawl after I wake my computer up from Sleep mode.  I have a WD My Book 2 TB.  Do I need to turn OFF the WDdrive before putting my computer in sleep mode?

you shouldn’t have to turn the hard drive off. However, if that fix your issue in the mean time you can try that.

Will be better if you contact wd to see if is a known issue.

Mine does the same thing. Installed WD MBL a few d ays ago. May be the software??
