Post in A sporadic but re-occurring problem with our Thermo QExactive plus unit

I encountered a similar problem where an automated file backup process would
cause acquisition to stop. I changed it from an automated script to manual
backup and no longer had the problem as long as I didn't do any big file
transfers during data acquisition.  If your problems are not solved by other
suggestions, then it could be some process interfering with disk access
competing with data acquisition software.  Virus scans etc?  In my case I am
running older XCalibur, v2.7 on windows 7.  Win 10 has an annoying propensity
to force software updates.  Maybe something running afoul there.

Best regards,
Brian

Are you writing to a network drive during acquisition?  if so, do the
data transfers after acquisition (you can trigger this with a post run
script)

if there is REALLY external network activity causing the issue,
perhaps try inserting a cheap home network router between your mass
spec and the wall plug.

I am really liking the other suggestions in this thread...

    * usb cables
    * acquisition PC is going bad  (perhaps try a memory check)
    * windows updates...
