FRITZ!Box reports "Could not complete the indexing of the storage medium"

The FRITZ!Box cannot generate the file index for one or more storage devices. When you try to update the file index with the FRITZ!Box user interface, the error message "Could not complete the indexing of the storage medium" is displayed.

Cause

  • The file index is corrupt, the storage in question is write-protected, or there is not enough space available on the storage.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Removing write protection

  1. Make sure that the USB storage device is not write-protected. Some USB memory sticks have a write-protection switch to enable write protection, for example.

2 Freeing up storage space

  1. Make sure that at least 10% of the storage capacity on the affected storage is available.

3 Enabling automatic file index refresh

Enable the FRITZ!Box's automatic file index refresh option so that the FRITZ!Box can automatically index new files when they are copied to a storage device connected to the FRITZ!Box:

  1. Click "Home Network" in the FRITZ!Box user interface.
  2. Click "USB / Storage" in the "Home Network" menu.
  3. Enable the option "Refresh index automatically".
  4. Click "Apply" to save the settings.

4 Deleting the file index

  1. Use SMB or FTP to access the storage device in question and switch to the directory \FRITZ\mediabox (for example call up \\fritz.box\FRITZ\mediabox in the Windows Explorer or smb://fritz.box/FRITZ/mediabox in the macOS Finder) on the storage device.
  2. Delete the database files for the file index. The file extension of the file index is ".db3", and the file name may vary, for example fritznasdb_part.db3 or fritznasdb_ptmp.db3.

5 Generating a new file index

  1. Open the FRITZ!NAS user interface (http://fritz.nas) to start generating the file index.
