Okay MSFN is back online, so I downloaded the two ZIP files that are labelled as v1.1 (4102225F & 4102226F)
http://www.msfn.org/board/topic/78592-enable4 … -137gb-barrier/

I SHA1 checked both and neither of them matched the one I was using from the bhdd31 pack. Checking the dates it actually matches the "4102225F" one but as I said, with a different checksum. There's also "4102226F" but it has this note attached:
"only for replacing an existing v4.10.2226 file"

but anyway if you could let me know which one you're using, it seems like I was maybe using a bad ESDI_506.PDR file.
4102225F - July 20th 2006, 1:38pm - 232cf58f76d44851e1888138e30ab5e501353723

This thread sums up all the differences (its 3 pages)

Pretty confusing but to sum it up - 4.10.2225 and 4.10.2226 are the official versioning numbers by Microsoft of updates released for esdi_506.pdr for Win98se.
Version 4.10.2230 is a made up number by a user on the MSFN forum called Maximus-Decim. It is just LLXX unofficial 48bit modified version of 4.10.2225 with a hex edit to change the version number to 4.10.2230. If you hex compare them they only have the version numbers changed in two places. You may want to check this in detail to verify on the link I posted above.
Also of note is a user called ' Fredledingue' on that link above mentions that they could only get the 48bit modded version of 4.10.2222 to work, so you may want to try that one as well.

I personally was using 4.10.2230 - SHA1 - a10c619e214f87da082cd0b0905e6613c689974f and it worked fine.
I later applied some Winme updates to my 98se install, and can't remember exactly why now but I have been using 4.90.3000 - SHA1 98abad358e29839bb042988bbc03adefc336c999 since then. It also works fine on my 1TB drive, no corruption. You could try that version to.
You can get the Winme 4.90.3000 version from here:

the file is called ME48BLBA.EXE, open it with 7zip.

Just One last thing, when you copied the files in the earlier post booting directly to real mode dos 7.1, did you also check the hash of the original 20 files again, not just the copied ones? Sometime the corruption can affect parts below <137GB when you write above it.
