need help hotswapping. need to repair original dashes

hey, i need help hotswapping. my hdd_driver is courrupt i think because it just keeps flashing "invalid filesize" i tried Fatxexplorer, didnt work. it just shuts down. i can NOT figure out how to use xboxhdm.

i have yet to try xlinux. if someone could point me to where to find it, and guide me how to use it.

i would prefer a windows program,

i have NO access to another modded xbox so yeah, that sucks.

i either need help gettng my original msdashes on my xbox, or to get the 007 gamesave on there so i can try my softmod again.
