HDD Help

PS2 with Modbo5.0 modchip and 10tb 3.5" WD Black HDD installed. Doesn't matter what variant of OPL or uLaunchELF the HDD isn't appearing in the listing. When booting from Mass (usb stick) and updating OPL settings the HDD has been populated with the normal folders or DVD, APPS, CD .... & etc. The HDD was empty prior to this.

The HDD does operate, if you install USB-Matrix.zip from Gusse Retro-Hack and follow the guide the HDD is recognised but the capacity is roughly 1 or 2 tb.

Does anyone know how or what software will format this HDD to use the full 10tb ?

Thank you
