Synology error

"Error code 38: drives cannot be found"

Quick fix

The error can lie in the drive slot on the Synology product or the drive itself.

Hint:

First, shut down your Synology product
In case you dispose of empty drives, place them in your Synology product and try installing DSM again.
In case of 2 or more bays in your Synology product, switch the order of the drives and try to install DSM again.
Use a manufacturer's diagnostic tool to run a disc scan in order to find out if the drives are healthy. Format the drives again and insert them again in your Synology product.

Synology error

"Error code 384: My Cloud, My Cloud Home, or My Passport Wireless products are not detected under Windows 10 Network"

Quick fix

This problem occurs because the "network browse" has been disabled on Windows 10 v1709 and higher. Another problem can be that SMB 1.0/CIFS File Sharing Support has been deactivated on Windows 10, Windows 10 Fall Creators Update version 1709 and higher.

The SMB 1.0 protocol is important for the Computer Browse service to populate the Windows Explorer Network node ("Network Neighborhood"). This legacy protocol does not route, has limited security and is long deprecated. As this service does not work without SMB 1.0, it is removed when SMB 1.0 is disabled.

Hint

Open the search bar on Windows 10, type "Windows features" in the search bar and by double-click turn Windows features off and on
Look for SMB 1.0/CIFS file sharing support
Check if the box and all others will auto populate and click OK
Restart your computer
