well, we are talking with a computer guy who says he knows of this type of problem happening. I did go on quickbooks website and they do say that it doesnt work on linux, or is not tested and supported, and snap serer 4200 using the quardianOS I found out is linux based.
I too assumed the HD might be going, as QB is the only actual program that is a server type, thus in constant contact with the server and being written too constantly. all other files are written only when saving, so a few seconds each time at most. I figured if the HD are failing, a program like QB would shows signs of it more so than small data files.
