System Restore
Solid State Disk Software Failure
The file system and the Linux operating system of a Scan2Net scanner are
very robust and forgiving. The file system has the ability to repair itself,
even if the system loses power during a disk write operation, a condition
which will almost certainly corrupt any Windows, Android or MAC OS
based computer.
Nevertheless, under certain circumstances it could happen that the
Scan2Net Linux software on the SSD becomes corrupt. Unexpected power
failures, hard power off cycles via the main power switch without a
previously controlled shut down and other unexpected terminations of the
operating system may cause this kind type of failure. Also, any
uncontrolled interrupt of a firmware update procedure or other functions
which involve writing to the main storage (SSD) are a potential risk to the
integrity of the firmware on the SSD. The Scan2Net operating system of
every WideTEK® or Bookeye® scanner is Linux based and although it
happens very rarely, the Linux operating system can be corrupted like any
other operating system; whether it is a Windows, Android, Mac or any
other OS.
If the Linux operating system or other parts of the SSD are corrupted, there
is still no need to replace the SSD, at least not before the restore
procedure is executed once. This procedure is similar to the procedures
necessary to restore a Windows, Android or Apple OS to a previous state.
Restore Points
There are up to two backup copies of the Scan2Net Linux operating system
stored on the internal SSD. The first one is generated during
manufacturing. This is the restore point “Factory Settings”. The second one
can be generated by the user at any time. This is the restore point “User
Settings”.
