When attempting to use a USB flash drive or SD card as a bootable backup or copy destination, Casper reports "This disk contains an incompatible disk layout"
and refuses to let you proceed.
The USB flash drive or SD card is reporting that it is a removable media type device (e.g., floppy drive) rather than a fixed media type device (e.g., hard drive). While it is common for fixed media type devices to define more than one partition, removable media type devices are expected to define only one partition. Consequently, Casper will not let you select as a destination any drive that identifies as a removable media device when the selected source drive contains more than one partition.
You must use a USB flash drive that identifies as a fixed media type device such as a Windows-2-Go compatible USB flash drive when the copy source defines more than one partition. Most USB flash drives are designed to identify as removable media type devices, but Microsoft encouraged manufacturers of USB flash drives to produce a special breed of flash drive that would identify as a fixed media type device to facilitate support for the Microsoft Windows' Windows-2-Go feature. These USB flash drives are adorned with the Windows-2-Go compatible logo.
In some cases Casper is unable to determine the removable media status of a device, and in these instances, Casper will assume the device is a removable media device. If you are using Casper 10, you can override this behavior by checking the Assume fixed media if unknown option.
Follow this procedure:
- Start Casper 10
- On the Tools menu , click Options
- On the General tab, in Settings under the Drive Detection section, check Assume fixed media if unknown
- Click OK to apply and save the settings.
