okay, so, here’s the deal…
somebody unplugged these drives from my Mac withOUT ejecting them first.
- a 2 TB My Passport Pro (connected via Thunderbolt)
- a 2 TB My Book Studio (connected via Firewire 800 to Thunderbolt adapter)
- a 2 TB My Book Studio (connected to the first My Book Studio via Firewire 800)
so i restarted then re-plugged them back in. they DID/DO mount. but i went ahead & opened the Mac Disk Utility app to run First Aid as per many years of habit.
i could do this for the My Book Studio’s, and they passed.
i could NOT do this for the My Passport Pro; wouldn’t give me an option to do so. i read some time ago that this was a known issue with the My Passport Pro’s & El Capitan; the solution was to use their (Western Digital’s) WD Drive Utilities app for such things instead.
so, i ran the tests on the My Passport Pro, & since it was there, also the 2 My Book Studio’s.
sometimes the “Quick Test” would pass on a couple of them, but every time, the “Complete Test” fails on all of them.
now, that raises a couple questions…
- why (as the title of this thread says) would one utility pass & the other fail?
- where is the “repair” function in the WD Drive Utilities app?
i don’t have any access to Windows or Linux, i only have Mac’s. in my searching i found an app that says it’ll give you the complete lowdown on a drive, so i ran the trial/demo for them. attached is a screenshot of part of it.
so i feel pretty confident that these drives are failing. so i guess what i really need to know is…
can i repair these with software or are they really dying?
