How To Complete Reset / Re-Install Qnap
First Way (My Advice);
1 – Power Off Nas and Plug out all HDDs,
2 – Start Qnap witout HDD’s
3 – A few minutes later, Qnapfinder should find your NAS. Start the setup.
4 – When Qnap ask you to Plug HDD, use only 1 HDD and complete setup.
5 – After 15 minutes, Qnap should format & Installation should complete. Now login device and go to RAID Managments screen. Plug all HDD’s, and start “Format” Process for all HDDs.
6 – If all HDD scan result is Good, Start building RAID at the same menu. This should take around 12 Hours to complete synronization.
Login Qnap and go to Administration Page -> Reset to Factory Defaults. This will Reset, Format and Install RAID system.
