This error 0x01 means an Abnormal reboot: power loss,  system crash, or other undefined abnormality. Removing the case fan or CPU fan from the board voids warranty as it will damage the internal components when they require to cool down. You can check the drive but more than likely the CPU has suffered damage due to improper cooling.   

Following up on this as issue was figured out this morning via a call to tech support with George.

I took the cover off and discovered the CPU fan was not turning when powered up. If I gave it a push, it would attempt to start, but no go. I have to assume that was the noise we had been hearing as the HDD seems to be humming along just fine.

I had a CPU fan here that was not an exact fit, but will do the job until the one I ordered from you gets here... hopefully a couple of days. 

I am not sure if there was permanent damage to the CPU. I am sure it did it no good! Been running just fine for about 4 hours since I put it back into service.

FYI Jose, the unit is 3 years old so warranty is past anyway. I should have followed up on the case fan issue when it was new. I was supposed to take a picture of it and send it to you folks, but I never got that done. My bad! It has been running just fine since it was new up until the CPU fan failed.

Quick question... forgive me if it should be in a new thread, but when I put the unit back in service I was careful to plug all of the camera cables back into the same port they came out of.  I put labels on them all. When it re-started they were not in the correct places, meaning labels were wrong as were masking settings, etc. 

Is there a way to make this NOT happen next time I have to pull it?
