Parted Magic Secure Erase Verification Level
I've been experimenting with the latest Parted Magic Secure Erase to wipe HDDs and SSDs. After the Secure Erase completes, I noticed in the logs that the verification level is 10%. Excerpt from the log:
WDC_WD5000AZLX-00JKKA0 (/dev/sda) SERIAL NUMBER: WD-WCC6Z0JJVNY0 SIZE:465.8G RESULTS:Successfully Erased
Secure Erase Method: Normal Secure Erase
Verification Level 10%
Does this mean that Secure Erase is only sampling 10% of the drive to verify that the drive has been erased? One of our customers asked us if it's possible for Secure Erase to perform a 100% verification. Probably overkill, but given the sensitive nature of our customer's environment, I can understand their question.
