I'm not sure if I am liking what I see on fdisk... it doesn't show sdb1. I hope it shows up when I run dd_rescue to other drive... =P

# fdisk /dev/sdb

Welcome to fdisk (util-linux 2.25.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

/dev/sdb: device contains a valid 'xfs' signature, it's strongly recommended to wipe the device by command wipefs(8) if this setup is unexpected to avoid possible collisions.

Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0xe684adb6.

Command (m for help): p
Disk /dev/sdb: 1.8 TiB, 2000398934016 bytes, 3907029168 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: 0xe684adb6



Command (m for help):



Do not use fdisk for osd drives. they are using the GPT partition structure. and depend on the GPT uuid to be correct. So use either parted or gdisk/cgdisk/sgdisk if you want to look at it.

writing a mbr partition table to the osd will break it naturally.

kind regards
