Physical drive and partition options

	Disk access method
	Controls how devices are accessed. Preferred access method is using physical devices. You should change this setting only if you cannot get your device listed in ZAR. This may apply to some models of USB "key-disks" and flash memory cards (especially when a flash memory card is accessed via the digital camera rather than a card reader device). When "logical drive" method is used, you will not be prompted to select a volume (partition) since each device represents a separate volume. Additionally, loading a disk image file is impossible if access via logical drives is selected.

	Check for MBR/LDM information on removable drives
	If enabled, ZAR attempts to read and analyze partition table layout on removable drives. Some removable devices (like ZIP disks) do not store this information, so analysis attempt gives bogus if any results. In such a case proceed by using "Manual" partition selection option, and specify that there was only one volume on the disk.

	Read and parse LDM (Dynamic Disk) information
	LDM (Logical Disk Manager) is a Windows 2000/XP and higher component which implements Dynamic Disks features, including striped, spanned, and fault-tolerant volumes. Its database is read and analyzed to extract dynamic volumes layout. The dynamic disks are not allowed on removable devices and on the laptop computers, hence you may disable this option if this is your case. Additionally, it should be disabled if there are no dynamic disks and physical problems prevent reading of the database.

I am not tech savy at all... which is how I somehow reformatted the disc in my digital camera on the last day of vacation, and lost all my photos and videos. I came across this download and gave it a try. [...] I did have to refer back to the demo for guidance on selecting the right "physical device". The selections it gave me were unrecognizable to me. The demo helped me understand what I was looking for. All pictures are recovered, and I am grateful! The movies were recovered as pictures (large jpeg files). I can't figure out how to convert them back to movies. Regardless, I am thrilled to have my pictures back.
