I'm having the same problem. I swapped my Macbook's internal HDD with a bigger one and i did a full system restore from my Time Machine disk. The process was ok and the new system is working right as it was before.
But now, when i plug the Time Machine disk it stays for long minutes in "preparing" and then when it starts backupping it does so at a speed of about 2kb per minute.
I run a disk check and the external HDD is ok, i'm sure the USB cables are working properly, but Time Machine became unusable.
And i noticed (after the restore) the appearence of a private>tempVM>something... folder in my Time Machine HDD.
Any suggestion? I'd rather not wipe out the TM disk, i've got months of backup in it...
