Hard drive error hopper with sling

[AndyNicholas]

Kind of a long story but I think it is important to cover all the details. My system consist of 2 hopper with slings and 2 joeys. Both hopper with slings have ota modules plugged into usb ports. Out of no where, 1 hopper kept saying hard drive failure unplug and replug. I tried this multiple times but was unable to get the error to go away or recover the reordings. Called dish. They had me restore to factory defaults. Still same error appears. They send me new receiver. Hooked it up, seems to be working ok. Go to other room turn on 2nd (old) hopper with sling. Hard drive failure, I am severely ticked off at this point. Unplug, reset, still failing. I decide at this point to unplug the ota module and restart. All recordings came back, no more errors. Anyone have a similar experience? I wish I had figured this out before replacing the old receiver, disappointed that dish didn't ask me to try this 1st instead of just telling me to factory reset.
