Troubleshooting (Advanced)
Disabling auto-defragment
Windows automatically processes "defragment" to speed up in accessing files, etc.
However, this process is not always necessary because you can access files at high speed even if they are decentrally-saved
in the flash memory. Also, we recommend disabling auto-defragment because reducing the number of writing times is effec-
tive to use the flash memory for a long period of time.
NOTE
If auto-defragment is disabled, this function will not work when an external hard disc is connected, too. Change the
setting when necessary to prevent the computer performance from being affected.
