Data Loss due to Mechanical Influences, Software-Influences or Faulty Operation
The use of a RAID-system – even of a RAID 1 – does not make a thought-through
data backup unneccassary.
Important data should always be saved onto a seperate
drive and be stored away.
Then even an “stampede” can go through your working
space and you can enjoy the sight. Software-viruses are interesting by themselves
– unless it just encrypted your RAID 1 and your backup was also connected to your
computer and is now also encrypted. A nice-smelling cup of coffee can destroy a
system – with two systems this is much less likely. With these images we want to
illustrate the term “Data Loss due to Mechanical Influences, Software-Influences or
Faulty Operation“ and make clear the meaning of a good backup.
Reading of Hard Drive Information
To be able to judge the quality of hard drives, usually so-called SMART-techniques
are used.
With RAID-systems the reading of SMART-information of the individual
hard drives is not readily possible.
For the QB-35U31R the SMART-information of
the first hard drive of both sets can be read.
Secure Removing of the Hard Drive
The QB-35U31R is a USB hard drive enclosure and fromt the vantage point of
many operating systems a removable disk. Please execute “Safe Hardware Removal”
or “unmount” before turning off the enclosure or pulling of the data cable. Nor
-
mally this “unmounting” is done automatically by shutting down your PC, Notebook,
NAS, Router, Mediaplayer or Mac-Device.
In a Standby-Mode, Energy-Saving-Mode,
“Quickstart-Standby” etc. a removable disk might not be “safely removed”
and
disconnecting the data cable leads to data loss – even if you think your system is
“off”. We recommend to uncouple USB drives from the active file system with the
neccessary care. This means before you shut down your PC – if you want to discon
-
nect the cable.
