RAX80 does not recognize USB drive
I recently purchased an RAX80 and am trying to use it for Time Machine. I attached a GUID-partition-map, Mac OS extended-formatted portable USB drive, and while the device is clearly plugged in (pow...

Drive compatibility for ReadySHARE seems to be more like witchcraft than engineering. Earlier reports put 4 TB upper limit for compatibility. There was one report of 6 TB but I haven't seen it replicated.
I have a 4 TB WD Elements drive connected. It has its own power supply, so isn't a drain on the USB ports, which seems to be one issue.
The first thing to check is any strange partitioning on the USB drive. This is an absolute no no for ReadySHARE.
The bottom line is that ReadySHARE isn't something to rely on. A proper NAS is much better.
Well, apparently the RAX80 is not compatible with the Seagate 1TEAPF-500 (part number on drive) / STEA4000409 (as identified on purchase order). Even after leaving it plugged in overnight, the RAX80 never indicated that it has a USB storage device attached.
I tried plugging in a different Segate portable USB drive, this one a 2TB STGX2000400, and the system recognizes the drive right away. Bummer that a different USB drive from the same, well-known manufacture isn't compatible, but c'est la vie, I guess.
I'm now running into TIme Machine issues, but that's a different kettle of fish and I've got a fair bit of troubleshooting left to do.

So after some intermittent (and unsuccessful) attempts to get the 2TB drive to actually work with Time Machine, the router ended up hanging and I had to restart it. In the process, or perhaps because of the restart, the filesystem on the drive got damaged to the point of fsck (via Disk Utility) failing on the Mac:
Performing fsck_hfs -fy -x /dev/rdisk2s2
Checking Journaled HFS Plus volume.
Invalid node structure
The volume could not be verified completely.
File system check exit code is 8.
Restoring the original state found as unmounted.
File system verify or repair failed. : (-69845)....so I'm giving up. If there's any significant risk of the filesystem getting corrupted, there's not much point in trusting it as a backup device. I'm going to reformat the drive and go back to direct attachment to the computer.
