wd external hard drive mac cannont format not enough space

Oh, how I wish WD would look into clarifying what it puts on its website.įirst of all, there are two way to format to Mac: use Disk Utility or WD’s Utility Drive download. I’ve finally found the way to format a Windoze-platform My Book to the Mac platform. The backup disk is not in Mac OS Extended (Journaled_ format, which is required.”Įxactly what is a Mac user to do to properly format a Windows-formatted external hard drive? > Operation failed…Īs soon as that error message appeared, I got a similar error message from Time Machine saying “Time Machine couldn’t complete the backup to ‘My Book’. The details read: Unmounting disk > Couldn’t unmount disk. Here’s what it said: Erasing “My Book” and Creating “My Book Backups” Erase process has failed.

(Unfortunately, WD apparently doesn’t permit us to attach a screenshot to these posts sorry for my description of what was revealed). Here’s what I did: Using Disk Utility, I changed the name from “My Book” to “My Boob Backups” I immediately got an error message. Wish the web page suggested which option to select it simply states “Select” without suggesting what each selection enables. I chose “Max Extended Journaled” for the Erase process, however, maybe I should have picked a different format option. It doesn’t tell us which option in the drop-down format field to choose. The instructions on the WD “Format for Mac” page, when followed, didn’t work.
