Hi,

I'm developing an USB application for interfacing USB device. When I call the DeviceIOControl() with IOCTL call "IOCTL_DISK_GET_PARTITION_INFO", I get the error as "The network request is not supported"(i get the error code as 50 using GetLastError())

Can any one help me out from this?

Regards
Mohan

Solution 1

IOCTL_DISK_GET_PARTITION_INFO is superseded by IOCTL_DISK_GET_PARTITION_INFO_EX. More information here[^]

Solution 2

In the remarks section of IOCTL_DISK_GET_PARTITION_INFO[^] there's a table which shows for which disk types it's supported and a note on 64 bit systems; did you verify your disk is a valid target?
