I installed a new hard drive and am now trying to restore my old settings and documents from Time Machine, is there any way I selected the wrong disk and am deleting my time machine back ups?
How are you doing this -- starting from your Recovery HD and using Restore From Time Machine Backups, or did you erase your HD, reinstall OSX, and are using Setup/Migration Assistant?
Are you saying your backups aren't recognized?
If so, and your backups don't appear, you might have been bitten by a bug we've just found. See #D10 in Time Machine - Troubleshooting for a way to tell.
Let us know the results. If you do have the bug, we'll work out a recovery plan.
If you don't have the bug, we need to know just what you've been trying, and what's going wrong -- what do you see, or not see?
