I have a bunch of power supplies, but can’t work out which one belongs to my WDBAAU0030HBK-01 hard drive. I’ve checked out this page Power Adapters for Western Digital Products but can’t find my hard drive listed. Is it the same as the WDBAAU0020HBK? What’s the difference? I just want to know what …

Can't find my power supply specifications

WDBAAU0030HBK-01 = 3TB (Terabytes)
WDBAAU0020HBK = 2TB (Terabytes)

Your WD Power Supply will be a “KTEC” brand … see here <-click

buy a $2 pack of letter/number stick labels to avoid confusion
eg. mine
