sdb is formatted as ext4. Not sure why fdisk shows dos. When I plug the
drive into my ubuntu laptop it shows as ext4. Also,
root at orca:/home/mark# df -T /dev/sdb1
Filesystem Type 1K-blocks Used Available Use% Mounted on
/dev/sdb1 ext4 2884121824 1265247048 1472346776 47% /media/backup

I am using fuse to read the NTFS drive, and it works very well. I trade
movies etc with others who all have Windoz machines, so moving all the
files to ext4 would be a pain.
root at orca:/home/mark# df -T /dev/sdc1
Filesystem Type 1K-blocks Used Available Use% Mounted on
/dev/sdc1 fuseblk 1953480704 825650176 1127830528 43% /media/plex
Also, the NTFS drive is not causing the issue. It is the ext4 drive. If I
take out the ext4 drive the system boots without any issues. If I add the
ext4 drive and take out the NTFS drive, the system hangs.
