Seagate Central 4TB Teardown and data recovery

How I recovered from a cooked Seagate Central chassis. (YES this does void any warranty.) See Brandon Policani's video on how to open the chassis. https://www.youtube.com/watch?v=zwZwbrVGrTA Inside was a 4TB Segate Desktop 5900 RPM Drive. Seagate uses a customized version of Linux LVM to slice the drive into 8 partitions. I tried several different methods using Ubuntu and Knoppix to mount and copy out the data with zero success. SMART+ indicates the drive/chasis ran for about 3500 hours before cooking. Drive Model ST4000DM000-1f2168 Power Cycle Count 29. The drive has since been reformatted and now living in a real NAS chassis. Once you commit to the process, validate the old drive using some type of esata to USB adapter and a linux boot disk. You should see several small partitions all using LVM for the data partitions. Do Not alter the file system or attempt to write to the disk. All you want to do is see if a Linux boot disk sees valid partitions on the drive. IF you see valid partitions, it was only $10 more to buy another seagate central as opposed to a standalone drive. You can do the tear down of the new seagate central and re-insert the old drive into the new controller assembly. Be careful to use extra cooling when working with the seagate central. The screen mesh is deceptive, it's actually part of the the heat sink from the drive and controller assembly. Since you now have 2 drives, You can consider a real NAS chassis and have a mirrored volume once you are finished.
