Read Verify Sector Ext error!

[Robert P]

I just formatted a 1 TB WD Green SATA drive and ran, or tried to run WD LifeGuard diagnostics tests on it.

It passes the SMART test but the quick test and extended test both fail quickly with this message: Read Verify Sector Ext error!

After this happened the first time I tried a chkdsk, but am still getting this message.

What does this mean?

Thanks.

It means the drive has bad/failing sectors and needs to be replaced.
