The most common reason why only one Compact Flash Card is usable when multiple Compact Flash Cards are connected is due to a device signature collision.
If you are dealing with bootable devices and seeing this problem, we are confident a collision is the issue. If you are not dealing with a bootable device, then our information below will, probably, not help.
What is a Compact Flash Card signature collision?
A signature collision can happen on any bootable device, so Compact Flash Card cards, SD cards, microSD cards and USB flash drives. A disk signature is a unique identifier number (UID). It is a unique identifier stored as part of the MBR (Master Boot Record) for an operating system loaded on the device. The operating system will use the UID to identify and distinguish between storage devices. It is commonly made up of eight alphanumeric characters. A disk collision occurs when your operating system (Windows) detects that there are two disks with identical signatures.
For Windows 7, 8, 8.1 and 10, these versions of Windows will disable the second drive and will not allow that second volume to mount until the disk collision has been rectified. If you are reading this article, chances are, this is exactly what is happening to you.
The first thing to do is navigate to the Disk Management tool with in Windows. To do this, use the search tool and type in Disk Management. This will take you to the utility that Windows offers. Here you can see your multiple devices connected. If you click or hover over the device not working you will see one of two messages:

The USB-C200PC is believed to be a 3.1 based technology and will write at the devices maximum transfer rate. USB 3.1 has a theoretical maximum speed of 10 gigabits per second (Gbps). Keep in mind that is “theoretical” so your real world experience will never get that close.

Almost fifteen years ago Lexar announced it’s first 1GB SD card. Today Lexar announces their first 1TB SD card. My, how times have changed. A one GB card ten years ago cost about $125 and difficult to find at that capacity. The 1TB card announced today is $499.
If the price difference isn’t a big enough shock to you, consider the storage capacity increased this much, yet the form factor of the SD card has not changed.
This new Lexar card is a Class 10 device with transfer speeds over 95MB per second. Ideal for newer cameras capturing video in 4K.

With that in mind, we’ve all seen wall outlet USB charges, but the Snap Power, in my opinion, will rule them all.
The design is clever. Installation is ultra-easy. Accessibility supersedes all others.
Take a second and just look at it:
In my mind there are three things which make this a brilliant wall charger. If you don’t mind me walking you through the obvious, here we go.
Or skip the highlights and jump right over to their website:

Installation is very easy. Simply unscrew your current face-plate and replace it with the Snap Power face-plate. You can see from the picture below the screws used on the outlet behind the face-plate is what provides the juice for the Snap Power USB port. They have a patent on this, so it’s definitely a fresh idea.
I think the final point on why this USB charger is the end-all, be-all is the slim design. Take a look at
