#+title:wiiunhide

this is yet another application allows you to get rid of the annoying =Format Disk= nag when using a FAT32 USB harddrive on the wiiu. this is achieved by modifying a byte in the drive's MBR so that it appears to be hidden. because modifying a drive's MBR is a potentially risky operation, THIS APPLICATION IS USED AT YOUR OWN RISK. make sure you have a full backup of your drive before use.

this application was tested on Debian unstable and no others. in theory it should work on any unix-like where rust is supported. i doubt it will work on windows.

• INSTALLATION ** FROM CARGO with a proper Rust installation, the application can easily be installed with cargo:

#+begin_src shell cargo install wiiunhide #+end_src ** FROM BINARY a binary has been provided for Linux x86_64 in the Releases tab. place this in your =$PATH= and you're good to go.

• USAGE execute the application with the block device of your harddrive (=/dev/sde=, NOT =/dev/sde1=) to toggle the status:

#+begin_src shell $ wiiunhide /dev/sde #+end_src

be sure you have proper read/write access to this device before running. this can be achieved with =sudo= or setting up a udev rule for the device.

** CHECK running the application with the =-c= or =--check= flag will simply print the current status of the device without making any modifications:

#+begin_src shell $ wiiunhide --check /dev/sde wiiunhide 0.1 /dev/sde is currently VISIBLE #+end_src

** BACKUP AND RESTORE a backup of the drive's MBR (the first 512 bytes) is automatically created before any modifications are made. by default, it is saved as =mbr.bin= but can be customized with the =--backup-file [filename]= option.

the =--restore [filename]= command attempts to restore the drive's MBR from a =wiiunhide= backup file. this is a risky operation and should only be used as a last resort. again, USE AT YOUR OWN RISK.
