I upgraded the HD on a client's macbook yesterday and i am having the common time machine issue of it trying to backup the entire drive from scratch again but with one added wrinkle- all the old backups have vanished.
as soon as the upgrade was completed and i plugged the time machine drive in it started backing up. eventually it errorred that there was not enough harddrive space to complete the backup, which i found odd as the time machine drive is 500GB and internal drive is using less than 300 GB at the moment. it said something like 275GB were needed and only 245 were available. when i view the contents of the drive in finder the only files present are the most recent backup attempt, incomplete and finder reports the drives as being less than half full (250GB plus free). it seems to me like the old backups have somehow quasi vanished but the disk space they occupied isnt freed up. is that whats going on? any ideas how i get the old backups back? i'm thinking reformatting the time machine drive will allow me to start using it again without running out of space but theres some stuff in the old backups i'd like to recover.
