Q: Time machine drive replaced
I run OSX 10.8.5 on my main Mac Book Pro, backed up by a 1Tb Time Machine hard drive, which should be enough as most of my working files are on other drives, with only about 100Gb need ing to be backed up on t/m. I also use another MBP running OSX 10.9.5 for odd tasks which is not backed up at all - beyond system files there's nothing much on it.
When I started getting problems with the t/m drive, so as not to tie up my 'working' computer used my secondary machine in root mode to format another drive and copy the backup to a new drive.
Now, on connecting the new drive to my main computer, and altering the t/m pane in System Preferences the new drive wants to copy all my files on my main machine to t/m but, to the best of my understanding, it should only be copying altered files. The result is that the drive has run out of space.
How do I get it to recognise the new drive as a continuation of the old one?

If the original backup disk was erased (as you posted), I think you are better off starting over. Messing with the Time Machine file structure normally results in an unusable backup.
