i installed an OWC_SSD HD about a month ago and i want to now erase the original HD that came with the computer for extra storage.
when i go to utilities and hit erase, it tell me "erase process has failed. press done to continue.
what am i doing wrong? thanks
Can you repair (first aid) the HD via Disk Utility?
IS the HD in an external device and connected via USB?
You can assess files on the disk?
the hd is the original that came with the mac pro. it's mounted internally. i get this error when doing first aid. i can access all the files when i click on the disk.
That looks like you did not complete your conversion to your new drive, and still have open Files or Applications on the old drive that are precluding its unmounting.
Are you sure you are not still booting from this old drive?
It's a much, much faster computer when booting and opening programs so i'm sure that it's setup to boot from OWC.
see below.
i disabled spotlight but still having same issues
One of the suggestions on one of the other threads referenced suggested you:
boot to Recovery, and use its Disk Utility to do the erase.
after my last post i enabled spotlight after that failed to fix the issue. the next day i attempted to erase the HD and for whatever reason, it didn't give me an error and completed the format. So in the end i don't know what the fix actually was. It works now, so that all that matters in the end. thanks
can't erase my original HD on mac pro
