Problem when create rawdisk

[Emiliano Vazquez]

Hi folks.

I need boot from a USB device. i know i need to create a raw disk and
then use this vmdk as an internal disc.

The problem is i create the vmdk file but this file is empty (or is
incomplete).

#############################################################
$ time vboxmanage internalcommands createrawvmdk -filename test.vmdk
-rawdisk /dev/sdc
RAW host disk access VMDK file test.vmdk created successfully.

real 0m0.040s
user 0m0.021s
sys 0m0.024s
$
##############################################################

The file test.vmdk is created but it use a few milliseconds to do that!


Any help will be appreciated.

Emiliano.

So what is the problem here? Are you not able to boot from your usb
drive in the guest? The vmdk files created for a raw drive are in
fact very small, and take next to no time to create. If this is what
you are concerned about, then don't worry. All you described above
seems like it is what it should be.
