Matt, I think there has been a miscommunication. fdisk shows /dev/sdb1 as type Linux (0x83) - the Disklabel type is dos. (my error to say it was formatted as dos). This drive is causing the issues with booting. df shows it is ext4. root@orca:/home/mark# fdisk -l /dev/sdb Disk /dev/sdb: 2.7 TiB, 3000558944256 bytes, 732558336 sectors Units: sectors of 1 * 4096 = 4096 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: dos Disk identifier: 0x00028375 Device Boot Start End Sectors Size Id Type /dev/sdb1 256 732558335 732558080 2.7T 83 Linux The other USB drive, /dev/sdc1 is formatted as NTFS and I use fuse to access it. This drive is not causing the issues. I want that drive to be Windows compatible as I mentioned before. root@orca:/home/mark# fdisk -l /dev/sdc Disk /dev/sdc: 1.8 TiB, 2000365289472 bytes, 3906963456 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x48f9a2e9 Device Boot Start End Sectors Size Id Type /dev/sdc1 2048 3906963455 3906961408 1.8T 7 HPFS/NTFS/exFAT I don't think I have to change anything in the partition table for /dev/sdb1. Or, am I missing something?
