Hi there.

My mid 2010 27in Imac had been working fine with time machine until I had to move the machine to work elsewhere for a day.  When I got back and plugged everything in, I ran risk repair / permisssion repair using cmd R from startup then restarted.

All good except time machine sees the disc ok but wont recognise the old backup files as its own and wants to do a new 1.5Tb backup.


I cant see whats changed but Its like Time machine has disowned its old backup files.


Any suggestions very welcome indeed.


Thanks in advance



iMac, Mac OS X (10.7.5)
