If I add a new disk with the FAT32 file system and the volume label "123456789", My Computer displays the disk name as "12345678". The 9th character is not shown in My Computer.
Thank you for reporting this. You are right, that's a bug. We'll address it within a few days and also take this opportunity to review the entire formatting code to prevent similar issues. I'll post an update here once it's resolved.
The issue has now been resolved, and a new build is available for download.
If you are installing it over an existing copy of the RAM Disk app, please note that you will need to reboot twice for the updated driver to be fully replaced and loaded.
