    My USB drive shows up in Disk Utility but isn't mounting

    [EDIT: I'm no longer having this problem. I erased the USB drive in Disk Utility, which caused it to mount. However, now it's not showing up on the Windows laptop I'm using, which seems like a problem outside the scope of this forum. I may just transfer my files another way. Thanks to those who...

    Erase Free Space frozen

    So I'm using the Disk Utility to erase free space on my Macbook (running Mavericks). I had 77GB available on my 750GB drive before I started this. It got about 80% through (using the 3-pass version) and then seemingly froze on "creating secondary temp file"--and my available space had plummeted...

    Disk Utility Alternative for OS X

    Hi everyone Does anyone know of a good 3rd party disk utility for OS X ? The original disk utility doesn't always fix my hdd issues, but when I plug it into a Windows PC it fixes it. The new El Captain Disk Utility is pathetic! Any suggestions will be appreciated.
