FWIW, I have a M2513 external drive, off a cheap NCR controller. I was never able to mount a disk fdisk'ed with Windows' tools. If you dd|od one of your existing disks, you'll notice that the partitions actually begin at a different place from where Linux expects them. Certainly one (or more) of the fdisks and block drivers hardcodes sizeof(sector)==512 and then magically falls back on its feet when it did format the disk. Sounds like fixing this would require some kludges in the partition-table reading code (berk !)
Out of time and lack of a free cartdridge, I haven't yet tried to fdisk a MO with linux and then make a FAT system on it, to see whether Windows was able to read them. However, I was successfully able to fdisk and mke2fs a disk, using Linux. And it now works great : I compile my kernel, glibc and compiler trees from that disk. (of course, none of this can work on 2.0, which didn't understand 2048-byte sectors, from the little I've understood of that code.)
Good luck
