Hi all,

I have a DirecTV SDDVR80 running v6.2 that I upgraded by adding a 160GB drive. I want to hack it as well but I wanted to keep my shows and have a backup. I bought the exact same 160GB HDD and have been attempting to image it today. I downloaded and burned the PTVupgrade LBA48 Boot CD v4.04 and used the following command to copy the drive:

mfsbackup -Tao - /dev/hda | mfsrestore -i - /dev/hdb

It displayed these:

Source drive 78 hours
Upgraded to 174 hours

It began copying the 138000 MBs (approx). When it got to 85.19% complete and froze. I rebooted and tried again. Again it froze at 85.19%.

I figured there might be a defect or something on the source drive. I reinstalled the source to see if it booted ok and it did. I checked some programs and they seemed to be ok.

I then installed the target (new) drive. It booted up and it seems to be working ok. I thought if the complete system was there and only some of the programming was lost I could live with it. I checked several programs and had to delete some of them because they were lost.

I have restarted the copy process again it this time instead of 138??? it reports copying 137709. This time it froze up at 85.09% (117175 of 137709).

One thought I am having is maybe I never copied the 80 gig correctly. But the tivo says it has up to 136 hours which is not 140 but darn close. If I did only use 137GB when I created the first 160 drive wouldn't it have fewer hours then 136? Would tivo report this incorrectly?

My questions are:

- Has anyone had a problem like this before and is there anything I can do to help the copy process get passed 85.19%?

- What could have caused the problem? Could it be a problem with the target drive?

- Assuming the system portions of the HDD are intact on the new drive will tivo rebuild the other portions?

- Is it a bad idea to go forward with this partial copy?


Please give me your thoughts and ideas.

Thanks!

UPDATE: I orignally created the first 160 gig drive from an 80 gig using the 'Weaknees Custom Boot CD (with large drive support)'. I used it just now to copy from the original 160 to the new 160 and it worked perfectly. Very strange...
