Partitioning using Disk Utility Gone Wrong

betsyk42,

in the Finder, press Command-Shift-U to bring up your Utilities folder, and run Terminal there. In the Terminal window, give it the following commands, one per line, ending each line by pressing the Return key:

diskutil list

diskutil cs list

mount

df -m /

Please include in your reply the full output from these commands.

betsyk42,

the output shows that you still have only a single OS X partition, with no Windows partition, but that the OS X partition is 91% full. Log in as your administrative user and run the following command in Terminal to see where this space is being used:

sudo du -ms /Applications /Library /System /Users/* /opt /private /tmp /usr /var

(Note that the forum software might display this single-line command as multiple lines.)

This command will ask you for a password; give it your administrative user’s password. The password will not display as you type it in; this is a security measure.

Please include in your reply the full output from this command.

To resize (or delete) an existing partition without losing data, you will need to use, for example, iPartition:

betsyk42,

other than the line break which the forum software added, did you enter the sudo command exactly as it was given in my last reply?

If you did, then something in your administrative user’s Terminal environment is interfering with the execution of the du command. What output do the following Terminal commands produce when you’re logged in as your administrative user?

echo "${PATH}"

which du

EDIT: betsyk42, your last post didn’t appear in the discussion when I’d entered this reply, so please ignore this reply, as it’s not relevant.

betsyk42,

the totals shown by the du command amount to around 121 GB, so that confirms the mystery of where that other space could be.

Do you use Time Machine to make regular backups? If so, then one possibility is that the other space might be taken up by Time Machine local snapshots. If you do use Time Machine, when was its last successful backup?

One thing that you could try, whether or not you use Time Machine, is to boot into Safe mode, which will make your MacBook Pro do a disk check as part of the boot process, and then run the df -m / command in Terminal there to see if the reported total changes at all.

betsyk42,

I wish you luck. 😉 I highly recommend that you use the Boot Camp Assistant to create the Windows partition rather than trying to do it manually in Disk Utility; the disk check in the Safe boot might have fixed the problem that was preventing the Boot Camp Assistant from working before.
