My MacBook is no longer recognizing my external hard drive in my finder windows or on my desktop. I looked for it in Disk Utilities, and it is there. I tried to mount it, but the mount button is not highlighted. What should I do?

There seems to be an error. When trying to verify, the following message pops up:

First Aid Failed
Disk Utility stopped verifying “Maggie Farmer” because the following error was encountered:
Filesystem verify or repair failed.

And when trying to repair, the following message pops up:

First Aid failed
Disk Utility stopped repairing “Maggie Farmer” because the following error was encountered:
Filesystem verify or repair failed

Can you get your data off of the drive then try a reformat?

I don't know how. My external hard drive is formated for Macs, so PCs don't recognize it. And I don't have another Mac to try to open it.

At this point, unless you want to try some data recovery apps/services, I think you are going to lose that data and a reformat is your only option left.

Yep, if you need the data, I'd grab a copy of DiskWarrior and see if you can fix/retrieve it with that, and if not, just reformat and see if it successfully erases. In fact, if you go that route, I'd zero the drive and let it mark off any bad sectors that may exist.

I've been also having a similar problem with my imation apollo HDD. It was listed in the disk utility and i could feel the HDD spinning as well. Unfortunately I couldn't find a good solution and I bought a new external HDD. The new one is working well...
