We need to erase data on the drive _before_ return/replacement.
The web interface does not have this option.
The drive is “World edition with blue rings”. Firmware version 02.00.15.
No information found in the docum or KB.
We know that the WD service will safely erase returned drives, but this is not acceptable for us.
By the way, the failure is data corruption on the disk.
I copy a medium size file (~ 20 MB) to the drive, and everything looks fine and good.
Then I compare the copy with the original, and there are some single bit errors!
No indication of any error appears in the web interface. It’s Linux… you get what you payed for…
