Just to let you (and IMDISK users) know that, at least in Italian Win2K, this won't work:
imdisk -a -f test.img -s 33828352 -m J: -p "/FS:FAT /q /y"
The /Y parameter is not accepted.
The workaround of feeding a confirmation with ECHO to it works though:
ECHO S|imdisk -a -f test.img -s 33828352 -m J: -p "/FS:FAT /q"
PSC suggested a nice way to check for which letter is used in each language, here you can find the threas and the small "final" batch snippet by me:
