I have been having trouble deleting the trash on my external My Book and it was recommend that I repair and reset the permissions. Both Verify Disk Permissions and Repair Disk Permissions are shaded and therefore can not do those.
I ran the disk utility and Verified Disk and it is telling me “The volume My Book was found corrupt and needs to be repaired”
Error: This disk needs to be repaired. Click Repair Disk.
I clicked Repair Disk and got the following error:
Error: couldn’t unmount disk
Anyone know what this means and how I proceed?
Thanks in advance.
