Hello all,

I just read the "testing USB-ZIP images" post, and would like to ask a
question that has some relation to it.

Some time ago on Win XP I wrote some code to make an USB stick bootable
(either as FDD or HDD), which worked (using the DeviceIOControl function and stuff like IOCTL_DISK_CREATE_DISK).

The idea was that I could (re)create USB sticks to look like any old OS
(from DOS upto W98).

The thing is I always needed to eject the stick and re-inserted it before
being able to place files onto it (starting with MSDOS.SYS and the like), as I've never found how to tell the OS to re-initialize what it knew about the stick ...

tl;dr:
Does anyone perhaps know how programmatically to tell the OS to
re-initialize an USB stick (so it becomes aware of newly created, removed or resized volumes etc.) ?

Regards,
Rudy Wieser

For Windows (cmdline) there's
RemoveDrive
Homepage: http://www.uwe-sieber.de/drivetools_e.html
he also has a restart

Another option:
C++ code source for USB device ejecting can be had from http://www.withopf.com/tools/deveject/

but I don't think there's restart code in there.

John,

Thanks. I've downloaded the C++ code and will take a peek to see how they
are dooing it.

but I don't think there's restart code in there.

Maybe I've not used the right term for it.. How else can I partition a
drive (USB or not), format it and use it directly afterwards without needing
to restart the OS ? As some point the OS needs to be made ware of the
changes ...

Sorry I don't know.
I recall DOS's Fdisk required a reboot; I don't know about modern OS's (especially EUFI).

I recall that usb device driver installs required a manual "unplug &
replug" in 2004.
