I've recently found that 2minutes soft padding has been automatically added

Also getting a lot of failed daily calls (network connection, but I can still ping Tivo immediatelly after failed call)
I've got less than 5% used on one of Daves EXCELLENT

I've another 2 vanilla Tivos in the attic which I could swap the HDD into if the memory is starting to go faulty - would I have to set thumbs etc onto the new boxes, or is this info held on the HDD?
TIA, Penny
