Here’s a quick & dirty sample to dump some info regarding your UMD Firmware.

http://silverspring.lan.st/umd_ver_check.rar

It’s a 3.xx app (source included), works on both slim & fat.

Will dump a file called umd.bin into root of MS.

In it will say something like:

SCEI UMD ROM DRIVE 1.090 Oct18 ,2004

Your UMD FW version will be at least 1.090 or above unless you have an early batch 1.00 JP model AND you have never used an official SCE updater (note: downgrading your normal psp fw version wont downgrade the umd fw version – so downgrading back to 1.00 wont work).

For another reference, here is one from pretty recent JP slim (came with 3.72):

SCEI UMD ROM DRIVE 1.240 Nov10 ,2006

Also there are a few numbers before this string appears but I couldnt figure out what they represented.

EDIT:

Ok, so the data is just in the standard ATAPI INQUIRY data format.

So:
- the drive reports to the host as a “CDROM Device” (0×5 in the Device Type field).
- that the medium is removable (RMB bit set to 1).
- is not standard in either ANSI/ECMA/ISO (all set to 0)
- Response Data Format (2)
- ATAPI Transport Version (3)
- Vendor ID is “SCEI”
- Product ID is “UMD ROM DRIVE”
- a blank Product Revision Level
- Vendor Specific info “1.240 Nov10 ,2006″
