I have problem that prevents me from making Time Machine backup at all. First, some information about my environment:

- MacBook MB404 (late 2008)

- Mac OS X 10.7 Lion

- External USB hard disk drive (Samsung)

I'm using this configuration for years, before Lion everything was working pretty well. Unfortunately, on Lion from time to time I have to erase my external disc drive which contains Time Machine backups and start taking a new backup. Otherwise backups are extremely slow and taking couple hours just to save about 100MB on external drive. That's not a big problem for me, so every two or three months I'm erasing my external drive using Disk Utility, configuring TM from scratch and taking first backup again.

Yesterday was the day TM starts working very slow, so I decided to repeat mentioned process. Everything went good to the moment Time Machine started making a new, first backup on a erased drive. It is still so slow, it wont be done in a week or more. I know, that this is the fist and clean backup, and TM have to copy over 60GB of data from MacBook's hard disk drive to external disk drive, connected by USB, so it have to be time-consuming, but it wasn't take more than 6-8 hours before for the same amount of data! I have already fixed permissions on the disk using Recovery HD partition, but I didn't help, TM is still so slow it almost impossible to make a backup. I have checked MacBook's disk and external Samsung disk - both seams to be in good shape, there are no errors in S.M.A.R.T, Disk Utility says that everything is OK. What else can I do to fix this issue?

MacBook, Mac OS X (10.7.5)
