the largest lockable HDD is the
Maxtor K01J300pWhen installing that HDD, you will need a bios that supports LBA48 with a G drive. If you download one of the newer xecuter bioses, you will see that it comes with two files, one with .06, and one with .67. The .06 referes to only having partition 6, which is the F drive. .67 refers to having the F drive and the G drive. Technically, you could have 300 gb HDD w/ the .06 bios, but then your data would eventually corrupt (FATX doesn't like partitions over 250 gb). You would need to reflash your chip w/ a bios that supports lba48. If you want to use a different bios (like the evox m7 bios) that isn't already patched for LBA48, you can edit the bios with xbtool. Reflash your chip, then format the G drive using an evox boot disc, and then edit your programs to recognize the g drive. After that, lock your HDD, and you'll be ready to go.
