Hi, everyone.

 

Do you have bad drive when you have a pre-clear pre-read fail? Not sure what it means. Any knowledge is good knowledge.  thanks in advance!

Please share your diagnostics file.

syslog.txt

 

Hope that is the correct log.

Apparently your USB connection dropped (cable, controller, hard drive or driver) and the preclear failed.

Since these are no media errors, I would recommend you to change the USB port you're using and verify all power and data connections of the hard disk prior to a new test.

thank you so much! Once other drives are done I will re test this one.
