Writing of images to 32 GB USB stick fails under Windows

[mbarringer]

Interesting. Which version of Windows was this tested on?

[ajaeger]

Apparently with any version that was tried, so seems to be a 32 GB limit somewhere...

[mbarringer]

Yes, I had forgotten that the 16GB limit is hardcoded. When I wrote it originally, 16GB was a pretty clear sign that the device was a hard drive rather than a USB stick and I couldn't find another way to distinguish them. I'll remove the limit.

I actually wouldn't completely remove it, but maybe show a hint for bigger disks. It's very helpful that ImageWriter is protecting the user to not overwrite harddisks. It would be a pity to complete remove this protection.

you can hex edit the exe file to remove or change this limit.
search for the 16bit unicode string around offset 0x5ed9:
"SELECT * FROM Win32_DiskDrive WHERE InterfaceType = "USB" AND Size <= 17179869184"

Then alter the value "17179869184" (ie 16GB) to be a larger value.
Out of simplicity I just changed it to be 97179869184 which easily allowed me to use my 32gb sd card.
