Burn the Sheriff CSM ISO Image to a USB Drive

This procedure is a prerequisite to updating Sheriff CSM offline or restoring the software on a hardware appliance to its factory settings. For details, see Update Sheriff CSM Offline or Restore Software on Sheriff CSM Hardware.

Important: This process deletes all files stored on the USB device.

You must have already downloaded the ISO image from Sheriff. For instructions, see Download a Sheriff CSM ISO Image.

The procedure is different based on the operating system you use. Follow the steps accordingly.

To burn the ISO image from a Linux machine

To burn the image from a Mac OS X machine

Insert the USB drive into the USB port on your computer.
To list the devices connected to your computer, open a terminal and run the following command
```
diskutil list
```
To identify the USB device, look for DOS_FAT_32 as the disk type.
The location of the USB device in the following illustration is /dev/disk1.
Before burning the image, unmount your USB device
```
diskutil unmountDisk <USB_device_location>
```
Following the example above, the command would look like this
```
diskutil unmountDisk /dev/disk1
```
Copy the image
```
sudo dd if=<Sheriff_image.iso> of=<USB_device> bs=1m
```
Where
- <Sheriff_image.iso> is the full path of the ISO image file.
- <Sheriff_device> is the USB device location.
  For example, if you save the image file in /home/user/temp/image.iso and the USB device location is /dev/disk1, the command would be:
```
sudo dd if=/home/user/temp/image.iso of=/dev/disk1 bs=1m
```
Eject the USB device
```
diskutil eject <USB_device>
```

To burn the image from a Windows machine

Insert the USB drive.
If you haven't already, download Win32 Disk Imager from SourceForge and install it on your computer.

Win32 Disk Imager is a tool for writing images to USB drives
Launch Win32DiskImager and select the image file.

Win32 Disk Imager populates the Device field with the USB drive automatically.
To verify that the ISO image is the correct one, select MD5 Hash.
Win32 Disk Imager checks the image file and displays its MD5 checksum. Confirm that it matches the one received from Support.
Click Write.
Confirm while prompted.
Exit Win32 Disk Imager after the progress completes.
Eject the USB drive.
