1. In order copy a flash drive to an image on the local drive do the following:
- Make a mount point for the usb stick in the /dev directory of cygwin at a bash terminal. Use “mkdir /dev/usbdrive” for example
- Go to computer, right click::”manage”, then disk manager and locate the physical drive number of the usb drive. In this case the drive was found at physical drive 3.
- Mount the usb drive with a command like this “mount //./physicaldrive3 /dev/usbdrive”
- Use dd to copy the image eg.: “dd if=/dev/usbdrive of=/tmp/usbdrive.img bs=1M”
- Find the partition name with “cat /proc/partitions”
major minor #blocks name
8 0 29309015 sda8 1 102400 sda1
8 2 29205592 sda2
8 16 976762584 sdb
8 17 976759808 sdb1
8 32 732574583 sdc
8 33 732572032 sdc1
8 48 3906560 sdd
8 49 3906528 sdd1
- In this case I was looking for a 4 GB partition for my 4 GB USB drive, so /dev/sdd is the interesting device. Don’t use sdd1 as that is the partition, and what you want to write to is /dev/sdd the DEVICE
- So the right command to copy the image to the flash drive is “dd if=/tmp/usbdrive.img of=/dev/sdd bs=1M”
