Yeah, I'll buy one if/when you make them available. Your price is very fair. I'll try to keep an eye out, but I'd appreciate a PM.
2TB would probably work with 48bit HDloader. Any larger woud probably not. That won't stop me from trying Toxic-OS or any of the other major mods to make a 3 or 4 TB drive work. The larger drives report to use 64+ bit LBA addressing which requires the host to actually realize that kind of addressing exists - drivers and/or firmware mods depending on the hardware. 2.1 TB is the limit with anything using any smaller addressing space.
toxicoOS only does 48bit LBA iirc. it's also horrendously outdated as far as HDloaders go and i only use it as a loader menu for .ELFs and other stuff. also, it requires a DMS4 pro or DMS4SE pro chip to use (i've heard some clone chips can run it though)
