WDC WD3200BEKT-75PVMT0 smart fail extended test pass?

S I get a popup saying hd will fail as a result of SMART test error as follows

test Option: QUICK TEST
Model Number: WDC WD3200BEKT-75PVMT0
Unit Serial Number: [Deleted]
Firmware Number: 01.01A01
Capacity: 320.07 GB
SMART Status: FAIL
Test Result: FAIL
Test Error Code: 06-Quick Test on drive 1 did not complete! Status code = 04 (Unknown failed test element), Failure Checkpoint = 96 (Unknown Test) SMART self-test did not complete on drive 1!
Test Time: 23:19:42, April 15, 2016

Extended test finds no errors.

Is drive reliable or not ?

Hi, can you please share the complete SMART information? If you are using the drive in a laptop I would get a USB to SATA connection and try in a different computer and see if the same happens. If you are using the drive on a desktop computer, I would connect the drive in a different SATA port and/or with a different SATA cable.

hello,
