When I run the WD utilities program on my Passport Ultra, it will scan and test the drive and then tells me that the drive has "passed." Then within 1 minute it then tells me that it has detected an error.
I had to send out an older WD disk last year and it cost me $$ to get the data off and the drive was shot anyway. Besides the Ultra, I also have a 2.0 TB and a 3.0 TB "My Books."
You think I'd learn?
