Problems linking files after reinstalling OS

[Gilles Caulier]

Hi Juan,

The reformatted disk has an updated UUID. This last one is used in the
database to identify the disk. As the disk UUID is not the same, the
item path from the database is broken.

To fix this problem open the DK Setup dialog and go to the Collections
page where you will find a list of the media registered in the
database. Select one corresponding to your disk and press on the
Update Path button on the right side.
Validate the dialogs and this must update the UUID from the disk on
the database.

Best regards
