dd.exe above 2 GiB

[Pat LaVarre]

Does the web offer a dd.exe for Windows that functions at and above 2
GiB/file?

P.S. I ask because ...

Google near comp.sys.ibm.pc.hardware.storage found for me the Cygwin
dd.exe for Windows, also the UnxUtils dd.exe for Windows ...

I want a dd.exe rather than just a copy so I can open-seek-write-close
to create a GiB/file in seconds rather than the minutes of
open-write-close.

I got thru installation of both of these dd.exe, in the process
acquiring bzip2 nroff tar col etc. ... but I think I'm seeing these
`dd` choke at just under 2 GiB/file in FAT 32 on Windows. If someone
here knows those dd have been seen to work up there, then we can blame
my installation, else I'm guessing the tools themselves.

When I write my own .java for Sun's Windows Java, I find can get up as
far as 4 GiB in FAT 32, and perhaps more in NTFS. In FAT 32, I can
appear to create files at about 2 GiB/ minutes: about 4X what copying
is. Via dd or .java or .c in Linux I can get up as far as 4 GiB in
vfat and farther in ext3. Indeed, in ext3, I can appear to create
files of multiple GiB in seconds. By one "GiB" I mean 1 * (1 << 30)
bytes = 1,073,741,824 bytes > 1e+9 bytes.
