Help with Upgraded HDD on Original Xbox

[ZuNinja]

Hello, I was just wondering if anyone knew about this or can give me some tips.
I recently softmodded my cousin's Xbox using SID 3.1 or 5 (I don't remember which)
After the softmod (I installed UnleashX and then afterward I switched to XBMC),
I upgraded the stock HDD to a 500gb Western Digital IDE drive
using the XboxHDM tool. The Xbox itself is stock, nothing else has ben changed exept the HDD.
The problem I'm having is that, even though I upgraded to a 500gb drive, I only have approx. 124gb free
on the F drive, and the usual 400mb (approx.) on C drive and 4.37 (approx.) on E drive. Is there a way for
me to access the rest of the memory of the drive I installed?

Thanks in advance if you help. I can provide more details if needed.

Can't say I have any personal experience with this, however a bit of searching gave me this;

Note: XBMC only supports F: and G: partitions for harddrives and 512GB per partition!
If you want to install a harddrive larger than 137GB then you need a LBA48 compatible Xbox 'hacked' BIOS.
If a partition is larger than 256GB, the harddrive needs to be formatted with 32k clusters, use XBpartitioner.
XBpartitioner is used to partition extra partitions such as F: and G: (not the default C:, E:, X:, Y: and Z
Largest partition supported by a LBA48 BIOS and 32k clusters is 512GB, so 512GB+ need G: partition.
If you want to continue to play on Microsoft Xbox Live online-gaming service then you must lock the harddrive.

What I've gleaned from this is that you'll need to format the drive in a particular way using a particular tool, described above. Hopefully this helps set you in the right direction.

Ah thank you! That tool was perfect! I divided the leftover space between two partitions!
It works perfecly! Although I wasn't able to figure out how to switch the cluster size, but
I didn't need to switch the bios! Thank you so very much! If I can help you in any way, please let me know!
