Thanks for the heads up infinete. I'd get them elsewhere myself, but perhaps look replacing the storage device (I assume they're on SD?) If internal, perhaps the machine is playing up? Hopefully not that!

for those under linux I've found a way to do hide /unhide the drive:

this is for experienced users, as the dd command can be very dangerous, if you don't know what the 'dd' command does.. then you are better booting windows and using jayjay123's program. Always read twice before pushing enter key. and each person is responsible for not messing their MBR.

first make very very sure you know which drive is the one you want to hide, for this example I'll use /dev/sdx
also, make sure you use /dev/sdx (with NO number) instead of /dev/sdx1 /dev/sdx2 etc...

typing the command dmesg after plugging the drive should point you to the correct letter.
(/dev/sda is most likely your boot disk, so NEVER use that one)

we first need to make a backup of the MBR:

as root run:
dd if=/dev/sdx of=/root/mbr.bin bs=512 count=1

next we edit mbr.bin with an hex editor, something like okteta
change the last byte from AA to AB
and then save it as mbrhidden.bin

then we have to write it back to the drive
again, be absolutely sure you are using the correct drive or you will end up with an unbootable system.

dd if=/root/mbrhidden.bin of=/dev/sdx bs=512 count=1

and that makes it hidden

if you want to unhide it again simply write the original mbr.bin:

dd if=/root/mbr.bin of=/dev/sde bs=512 count=1

and unplug/plug the drive

As a computer technician, I can attest to this. DO NOT UNDER ANY CIRCUMSTANCES USE THIS METHOD, IF YOU DON'T KNOW WHAT YOU'RE DOING! Messing with the master boot record (MBR) is extremely risky, always check and double check that you understand all the instructions and every step of the way, otherwise you could wind up with a bricked drive thats unrecoverable (bye bye games!).

I'm feeling pretty inept here, I have downloaded the R8 Ustealth to conceal my drive and it won't run. I'm assuming there is a GUI here but nothing happens.

for those apps (like nintendont) that use the signature check built into libFAT I've recompiled it with UStealth support for anyone interested
http://www.mediafire.com/download/9d1ffxo16kc1gmq/libfatmod.zip
this would probably fix several apps by just replacing the existing one in your devkitpro and recompiling




if you're curious, the change was at line 183 in partition.c (code included)

    can't walk in a straight line very well with the analog stick of the n64 controller in zelda. the analog stick on the ps5 controller is extremely comfortable by comparison though.

    that 5-7 is a doozy. that's when my doctor thought I had Parkinson's. the day he thought that, I dropped the controller multiple times while playing through it.

    the upward/downward movements of the sling shot or bow and arrow use those inverted controls like flight games.

    think I broke my first 360, a xenon, or at least damaged it while under the influence of ambien (took like 3 or 4 of them), so the top of my entertainment center is majorly scratched. that's when I was trying to play ace combat 6. I don't have much memory of it other than the system falling over multiple times causing the scratches. not a very proud moment. no longer have that system.
