Writing to PrivateDisk-Volume fails although there seems to be enough free space available.
Copying a file or trying to create a new file in the root leads to messages similar to the following:
Error copying File or Folder:
Cannot copy xxx: The directory or file cannot be created
Unable to create file:
Unable to create the file <filename>
The directory or file cannot be created.

This behaviour can occur on FAT formatted volumes due to limitations of the filesystem itself.
The root directory of FAT12 and FAT16 volumes are preassigned to store 256 directory entries, which places an upper limit on the number of files and directories that can be stored in the ROOT DIRECTORY.
FAT formatted PrivateDisk volumes with a size less than 2 GB are automatically formatted with FAT16 (< 17 MB use FAT12). The directory entry limitation is only related to the root directory
What To Do
Do the following workarounds:
- Save the data in folders (not in the root directory)
- Format the PD-Volume with FAT32
