Bug in SCSIFS

If I put a USB pen drive in the slot it appears as a fat32fs device. It has a 31Mbyte FAT partition on it.

If I open a directory viewer using Filer_OpenDir SCSI::0.$ then I can see the files and write to and read from the drive but filetype information is not always remembered, see below:

I thought that was because Filer_OpenDir SCSI::0.$ bypasses Fat32FS and uses DOSFS instead. Is that really a bug?

I think so. I have a headless Pi that writes a log to a SCSI pen drive, using SCSI::0.$.Filename – writing to the root directory is OK but strange things happen when writing to a sub directory via SCSI.
