External USB problems

Seem to be having trouble here. I have a 10TB WDPurple in 2nd usb slot. Seems to work intermittently. I actually moved it to an external usb and did network share. I originally had as NFTS and had permissions nightmare. Offloaded programs, reformatted as exfat and reloaded files. Day off and trying to troubleshoot.

Edit: formatted at same time. But, my 64gb exfat usb drive works fine. Only thing I can think of different is a 4k alignment on my 10tb drive.

Getting the following errors:
[rootedur-server /IS [ 816.7097011 sd 1:0:0:0: [sdb] Detected SBC vers:


816.7132281 sd 1:0:0:0: [sdbJ Reattaching UPDs

[ 824.8457531 exFAT-fs (sdb1): failed to load alloc-bitmap

824.8474211 exFAT-fs (sdb1): failed to recognize exfat type

Any ideas?

What is this USB drive plugged into? The 2nd USB slot of what platform?

If this is a Shield there is an update to fix problem with external storage ..... but you do not mention where you are running channels dvr.

What’s New in 9.1.1?

  • Resolves issue where TV remote would not control SHIELD 30 seconds after waking SHIELD
  • Resolves issues with CEC volume control not functioning properly on AV receivers or soundbars
  • Fixes bug with files not detected properly on connected removable storage
  • Resolves issue with SHIELD TV app not launching on select Samsung Galaxy phones
