I can't find an answear to this problem anywhere!
I'm new in the forum and just bought my first external hd too. It's a Hitachi Lifestudio desk 2 TB, which I've formated to FAT32 with "FAT32 Format" program.
The problem is:
the ps3 recognise it and I can open photos, videos, etc. multiMAN does too, but it doesn't display the games!
In multiMAN it appears as dev_usb081. I've tried to edit the option.ini like this:
# Secondary search folders:
hdd_home2=/dev_hdd0/GAMEZ
hdd_home3=/dev_hdd0/game/OMAN46756/GAMEZ
hdd_home4=/dev_hdd0/game/LAUN12345/GAMEZ
hdd_home5=/dev_hdd0/BDRIPS
hdd_home3=/dev_usb081/GAMES
hdd_home4=/dev_usb081/GAMEZ
hdd_home5=/dev_usb071/GAMES
usb_home2=/GAMEZ
usb_home3=/BDRIPS
usb_home4=/_SKIP_
#usb_home5=/_skip_

but it still doesn't work!
PLEASE SOMEONE HELP ME. I fell like I have thrown money away buying this HD and that's awful ¬¬

Thank you and sorry for any grammar mistakes. English is not my native language :P
