I managed to do a full backup. First, on a Windows PC, I checked the Reader disk for bad sectors and it found some
. It said it repaired it so I tried (back on Linux) to dd again. No luck, same results. I then formatted the Reader partition in linux to Fat32 (not a quick format), followed by "format internal memory" on the Reader. Tried dd command and it worked.
Then I backed up each individual partition individually as well.
I then checked each partition with
sudo fsck /dev/sdbX
where X is 1 through 10 (except 3, which is an extended partition). No errors reported but I got two warning messages for the Diag and fonts partitions:
Warning: file extends past end of file system
. I did some googling and it seems this might be normal for cramfs file systems. Can anyone confirm?
I then ran
sudo badblocks -v /dev/sdb4 > bad-blocks4
for each partition and none were found.
Now that I can look at all the system contents, can someone indicate if there's anything to check for possible issues?
Also, I do not have a full backup of my unit before the problem started. I know that backups shouldn't be shared but I was thinking if it was possible to get backups of all partitions except the ones containing the unique information (serial number, etc).
P.S. I removed all the ebooks from my system except two to eliminate the possibility of a corrupt epub.
