ThumbsPlus Volume Matching

 

Because ThumbsPlus must perform well in many different computing environments (standalone, with removable media, CD-ROMs, on networks, etc.), the volume matching rules are fairly complex. This enables ThumbsPlus to match quickly and easily a physical drive with a database record most of the time. There are sometimes complications and problems; this discussion and a peek at the volume information (File | Volumes | Properties) should help you understand what is happening behind the scenes.

ThumbsPlus matches physical volumes with the information in the database as follows:

The volume types are checked to see if they are compatible. The following chart shows which volume types are compatible with which others:

Fixed drives: If the serial numbers match, then the volumes match.

All types: If the labels do not match and are not blank, the volumes do not match.

All types: If the labels do match and either volume is a CD-ROM, the volumes match.

Network drives: If either the physical or database volume (or both) is a network volume, then the setting 'Match Network Drives Using Share Names' is used to determine whether the volumes match:

Match using share names OFF: If the labels matched, the volumes match.

Match using share names ON: If the network (connection) names match, the volumes match.

Other drive types: ThumbsPlus compares the connection name or synthesized CD-ROM label; if they match, then the volumes match.

Suggestions for improving this are always welcome; however, it is quite difficult to take into account all of the circumstances that occur in the real world!
