Why do I have 200 GB of "backup" on my main hard drive? Any how can I find and erase them?

CFever,

This is an easy fix. Go to System Preferences/Time Machine and I'll bet that TM is toggled on; toggle it off.

The next time you look, the TM segment of your drive will be erased - though most may need to reboot to make the changes click.

Accurate? Post here with your reaction to this hint, so others can profit from the information!

When you open FINDER, is there a folder titled 'backups? If not, have to tried 'search' or 'spotlight' to locate 'backups? By any chance is your disc partitioned?

You state that you have deleted all music, photos and videos from this drive. The graphic that you included in your query shows that these are still on the disc.

The simplest way of achieving your desired result is to open Disk Utility and erase all user data. However that does not tell us what 'backups' is. Pure speculation on my part, but if the disc is partitioned, maybe that is how it is represented on the graphic.

Click on the HDD on your desk top using Command 'I' and see if available space correlates with the the above graphic. If not this suggest a software issue.

If it does, you have to locate 'backups'. As alluded to previously, try SEARCH and SPOTLIGHT. 200GB is hard to hide. Another technique is to open finder and press COMMAND 'J'. Click on 'size' and 'calculate all sizes'. If one of those files is over 200 GB, you have located your culprit.

Better yet wait for someone who knows exactly what the problem is and will give a simple answer. I admit I'm grasping at straws here, but maybe I've at least given a bit of a starting point. Good luck.

Ciao.
