Weird Issue Fat Partition

I just built a PI4 and partitioned the SSD drive with a fat partition to allow the PI4 to boot off the SSD. When the machine first boots, it shows HardDisc4 in the Icon Bar but when you click on the drive, it quickly changes to Boot and then the contents of the Boot partition is displayed. Any way to fix that?

It’s a side-effect of the FAT partition being detected by FAT32FS, use right-click to open the drive instead of left-click, it will then open the FileCore drive.

If you mistakenly left-click, you can dismount the drive and then right-click. If there are files already open on the drive though, you’ll need to restart as the system usually crashes hard.

I had exactly the same problem, but Andrew Rawnsley pointed me to a newer versions of FAT32FS (mine was from 2020). Now the problem is solved.

I’m sure I’m running the latest FAT32FS and still have to right-click.

I’ve not looked at the FAT32FS source recently, to see if there’s some sort of check for an overlayed FAT as used on Pi’s/Pinebook etc. That might explain why some can left-click and others have to always right-click.

I think there’s a line in the !Config file in the ‘PreDesk’ folder that comes with the download that allows swapping of the mouse key actions.

I found the !Config file and uncommented the line, didn’t do anything for me. I just put an Obey file on my desktop to open SCSI::4 filer window that I can double click when I need. Thanks for the help everyone!

The example line given in the !Config file (Which is just an obey file which gets executed after RmLoading the module) will swop the buttons for drive :1.
So if you want to swop all the drives then your config file would look something like this:

| Configuration Options for Fat32Fs
| For instance to swop the Select & Adjust Buttons
FatSwopMouseButtons :0 On
FatSwopMouseButtons :1 On
FatSwopMouseButtons :2 On
FatSwopMouseButtons :3 On
FatSwopMouseButtons :4 On
FatSwopMouseButtons :5 On
FatSwopMouseButtons :6 On
FatSwopMouseButtons :7 On

Jeff,

That makes more sense to me. I will give that a try.

That did the trick. Thank you.
