I recently bought a WD My Book Essential 2 TB External Hard Drive with the goal in mind to use it to store game saves and installed games on it. However I found out that it is in NTFS format, and I know that the Xbox 360 uses FAT32 format. Regardless I plugged in my External HD and went to "system settings > Memory" to see the storage devices and saw that my external HD was recognized by the Xbox 360 giving me the normal "Configure Now" and "Customize" format settings. Now I want to use the custom format option so that not all of my External HD is formatted. When seleting that a popup tells me that the External HD isn't formatted or that its in a format that isn't recognized (because it is, its in NTFS format) and that it will erase all data on it.
Now here lies my question(s). (a) if I do format the External HD using the Xbox 360 custom option, will it only erase the 16GB that I want to use as storage (seeing as thats the max on any usb storage device no matter its actual size) or will it erase the entire 2 TB External Hard Drive? (b) Now if it only erases the set 16 GB and turns it to FAT32 format will the remaining memory remain in NTFS and functional on a PC or if it erases my entire External HD will it convert it all to FAT32 format and will it also be functional on a pc if done this way?
Sorry if these questions sound confusing, please ask me to clarify them further or ask for any additional info needed. Thanks in advance for the help.
