That error may be a sign your drive is failing (or not). You might want to run that disk repair again in a week or so just to keep an eye on things. If you get that same error again, it may be time to start thinking about a new drive. Hopefully you have some sort of backup.
Im getting the same signs. I havent re-run the disk repair since the last time.
Should I run it again?
I have a Cloud WD external drive but I never really figured out how to use it. Every time I try to transfer large amounts of data it disconnects in the middle and I have to do it all over again. Ive been thinking of getting the USB external, at least then I would know that it would transfer without breaking in them middle.
