Time Machine can't find old backups

[ShaunC]

Evening all,

A couple of days ago I upgraded my Macbooks harddrive, however today when I've attached my external harddrive to backup my data it wont allow me saying there isn't enough free space on the harddrive.

When I look in the harddrive the file Backups.backupdb is clearly viable.

And when I enter Time machine it has only one backup stored from Friday when I fitted the new harddrive.

So my questions are

Is there anyway of pointing out the old backups to Time Machine?

Or, worst case, is it perfectly fine to delete the file Backups.backupdb and just start a fresh?

You can erase the hard drive with Disk Utility and start a fresh. Disk Utility-->Select your backup drive (NOT your Macintosh HD)-->Erase tab-->Erase (bottom right hand corner)

So what if you dont want to delete it, and the back ups are still there how do you access them? ... i have the same issue but i dont want to delete them, i still want to access them.
