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:
Today Apple announced the new iPadOS will support USB thumb drives. The iPad has long been toughted a workers tablet from Apple, but the relaity is their iPad didn’t provide much functionality. In addition, the devices have limited storage.
With today’s announcement the above argument could get a little muted.
Update: We learned the iPad will allow other storage devices such as external hard drives and SD or microSD cards (with USB adapters). The USB port will also allow for HID devices, such as a USB mouse and keyboard. We are not sure if the iPad will support Bluetooth mouse and keyboard, but we’ve got to assume, right!
There is no word about the connection. The connection could be one of three; an adapter, USB-C socket size or the classic USB type A socket size.

Nexcopy put out a press release today announcing a USB Type C duplication Copier which is available for immediate purchase. The USB-C200PC is a twenty target USB-C socket duplicator which is PC based and loaded with software features.
Via EIN Presswire service, Nexcopy Inc the news release talks about the increased demand is due from Apple housing a USB-C socket for their computers and Iot, or Internet of Things, type products are using the USB-C socket more frequently. Because of this shift, the duplication equipment market has adjusted.
Because the Nexcopy duplicator is PC based does not mean you will lose functionality and speed. 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.
The USB-C200PC ships with the Drive Manager software and includes some fairly trick software features:
- Six copy modes
- Binary copy mode supports all formats; HFS, Ext2,3,4, Proprietary
- Unique data streaming to each USB-C socket
- Binary verification
- Erase and D.o.D. Erase for disk sanitization
- Data collection to extract files off USB-C devices
- Intuitive and informative Drive Manager software
- Upgradeable to PRO Series for USB-C write protection
- Upgradeable to PRO Series for USB-C partitioning
One interesting copy mode is the unique data streaming function. The data streaming function gives a user the ability to put unique data to each USB-C flash drive. This is of particular interest for software publishers and on-demand USB production sent from on-line, front end order fulfillment solutions.
Nexcopy is also well known for the PRO series duplicators that perform advanced functions to flash drives, such as USB write protection (USB read-only), partitions at the controller level, and serial number control for UFD identification. From the press release, these advanced functions will also be available on the USB-C200PC duplicator.
The USB-C duplicator has a list price of $1,299 and is available through on-line retails like Amazon, WalMart.com and NewEgg. If you are outside the United States, the product is available through a worldwide network of authorized resellers.
Micron, with the corporate office based in Boise Idaho,
introduces the c200 microSD card with a data storage range from 128GB to
1TB. No that wasn’t a typo, One Terabyte
of storage. The card was designed to
address the demand around 4K video recording and playback.
The card has read speeds near 100MB/s and write speeds of
near 95MB/s. The c200 card collection
can reach these speeds because of Dynamic SLC cache; which is intelligent maintenance
during idle time for sustained peak performance. The Micron microSD card uses the UHS-1 Speed
Class 3 for capture and Video Speed Class 30 for support. Meaning to get these transfer rates, the host
device must also be UHS-1 compliant.
In case you are wondering, the card uses Micron 98-layer
3D QLC NAND memory, which is cost effective for both consumers and commercial customers.
If you have an Android device, you can be even happier
with the card meeting the Application Performance Class 2 specification which
is built-in memory expansion for compatible Android devices.
The Application Performance Class 2 (A2) is defined by the
Secure Digital (SD) Physical 6.0 specification. A2 makes SD memory cards higher
performance devices than A1 devices by using functions of the Command Queuing
and Cache framework. The Application Performance Class can be applied to UHS
SDHC/SDXC Memory Card product family.
Here are 10 of the 60 incredible USB flash drive designs. This article was pulled from GetUSB.info which has all 60 custom USB flash drive designs. Apparently all these designs have been made for other clients. We didn’t know how detailed these could get, but you can clearly see there really is no limitation to what can be done…

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.
You know a product is a great idea when a couple of pictures describe the entire product.
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:
The design is brilliant. The User keeps both outlets available for normal use while a sleek looking USB port is added underneath. At the time of this article there is one USB socket, but visiting their website you can see two sockets, one on either side. They are constantly improving.
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
