My Hack Doesn't Read USB Thumbs MS-DOS format :(

[Meng83]

Hi!!
My build, that was working fine till a couple of days ago, seems not to be able to read usd thumbs formatted in ms-dos mode.
The only thumb working (and the only one displayed in finder) is formatted as "mac os journaled".
All thumbs are visible in disk utility, but partition name is grey and activation fails also after using s.o.s.
the are all working only if i format them as "macOS Journaled"...

i tried to activate them all but disk utility suggests me to try with sos again, but the result is always the same: disk "xxxxx" cannot be started (literal translation tom italian, i hope it's comprehensible!)
I have a macbook pro with lion and all thumbs are workin' fine
my build:
i7 3930k
gb x79s up5
32 gb ram
nvidia geforce gtx 770
ssd disk 256 GB

(all usb working perfectly with other devices, mouse, keyb, printer)

I had this too. Any FAT32 drive is not recognised. Not only USB thumbs, also HD's.

I gave up and reinstalled a backup that i had before i updated to 10.8.5. That upgrade was not the cause for it i believe, i was messing around with a USB storage devices kext to make a MacBookAir superdrive work.

I updated to 10.8.5 again with and FAT32's are seen now.

I managed to solve this. I guess i was off by one day when i was creating my USB thumb drive to install 10.8.5. The following day a new Unibeast was released and by remaking my thumb drive with the new version of unibeast the Exfat drives were now mountable. Grab a new copy of unibeast start over and reinstall. Worked for me.
