After making a file available via the "Drive" menu the target cannot access it

I have a V2 with a CSI card and the system is fully up-to-date but when I make an iso file available to the “target” via “Drive” menu and then reconnect the USB emulation cable from the target (or reboot the target (which is Win10 BTW)) the target cannot access the file and says that it doesn’t recognize the format or says it is corrupt.

What am I missing here - everything else is working OK

TIA Dave

Hi @softfoot , and welcome to the forum.

What kind of file is that? Did you check if it is really a corrupt file?
