USB Flash Drive Doesn’t Get Assigned a Drive Letter: Solution

You’ve connected a USB flash drive, heard the familiar Windows sound of connection, yet no drive letter shows up. You then go into Disk Management for Windows and you can see the device and memory, but no drive letter.

What should you do?

USB key in computer

Most times this process is automatic and Windows will asign a drive letter to any storage device connected to your PC, whether it be a USB stick or a USB hard drive, or any other mass storage device.

However; in the event a drive letter isn’t assigned there is a very quick way to get your computer back to working the way it should.

  1. Open Command Prompt as Administrator (search for CMD and right click to open as Admin)
  2. Type ‘diskpart’ and hit Enter.
  3. Once in the DISKPART type automount enable and click Enter.

If the above doesn’t do the trick, another issue may be at hand. Maybe some conflicting registry entries from past USB devices connected to the PC and for this reason the automount was disable, or no longer working properly.

Nexcopy has a registry cleaning tool specifically design for USB devices connected to your computer. This utility is an exe file that does not require installation and does not have spyware, malware or anything else. It’s from a company you may

Erase USB or Clean USB or Format USB?

We’ve seen these terms floating around in forums and How To’s for years when someone is explaining what to do with USB flash drives. I think most people glaze over the definitions of Clean, Erase and Format simply because they believe the terms are interchangeable, or they aren’t planning on doing the task mentioned in the post.

I hope the following information will clear up some terms and definitions so we can all better understand what people are talking about when passing along information about flash drives and the Clean, Erase and Format function.

All of these functions can be performed in your Windows 10 computer, or higher. I will start with the least complicated definition and task, and move along from there.

Format

This function is what 98% of Windows computer operators will use. This is the graphical interface inside Windows when you right click a drive letter and ask the operating system to format the drive. What is this function really doing?

Format is the least complicated of the tasks, and this function is removing the File Allocation Table of the USB and creating a new one. Said a simpler way… this function takes away the list of files sitting on the drive so it then appears blank with no data.

It’s important to note, the files are still on the drive, just not listed in an easy, organized manor which you can see through windows explorer (clicking on the drive letter to see the list of files).

Using the most basic file recovery software tools, like the one we wrote about several months back, you can recover all the files sitting on the drive.

Maybe a picture will help. Looking at the image below you can see the “data” is light grey. Meaning the data is still there, just not easily accessible. This data is what recovery software will look for, find, and list back on your drive. Also notice the boot code of the USB (if you want to load an operating system on your USB stick) isn’t touched either.

format usb flash drive

You might have questions if a USB flash drive should be formatted as FAT, FAT32, exFAT or NTFS and we did a great post about that a bit earlier as well.

Clean

The Clean function is a bit more in-depth than the format function. This function applies directly to the Master Boot Record (MBR) or boot code mentioned just above.

The Clean function will clear out boot code and will remove any partition on the flash drive. The partition of a flash drive is the information which tells a host computer how big the drive is, and if the partition should be bootable in the event you are trying to start the computer from a flash drive.

The Clean function is not accessible through the GUI of Windows, for example you cannot right click on a drive letter and find the Clean function. The Clean function is only accessible through the Windows utility called DiskPart.

Flash Drive Prices Are Going Up – Cause: Japan & S. Korea Trade War

Japan has been a long time supplier for three key elements used in the manufacturing of NAND memory and semiconductors. Because of recent trade war issues between Japan and South Korea, these elements are getting very hard to obtain.

Japan produces about 90% of the world’s supply of flurinated polyimide and resists, and about 70% of the world’s supply for hydrogen fluoride. This puts everyone at risk if Japan will not supply those demanding it.

Those chemicals are used by Korean manufacturers to produce semiconductors, and are crucial for making components — including memory chips, microprocessors and integrated circuits.

We have seen the direct impact already. For the first time in over eight months, the price of NAND memory for flash drives have gone up. For each GB capacity the percentage increase is different, but most notably are the 32GB and 64GB wafers. They have jumped nearly 25% from the previous week ( this article was posted on July 25th).

Japan has sited inadequate management of those chemicals by purchasing countries. Said another way, these chemicals can also be used to manufacturer military weapons and Japan is claiming those supplies have been diverted to do just that. Japan’s response; restrictions on the chemicals.

Who will lose from this trade war? None other than any person who uses technology. Cell phones, processors, flash memory, circuit boards, the list goes on.

To learn more about the polyimide chemicals a quick read on this wiki page is fairly interesting. Continue Reading

QuadCore Raspberry Pi 4

Update:

From this article, the Raspberry Pi 4’s USB-C power port was designed outside of official USB-IF specifications, making it incompatible with many USB-C chargers and/or power supplies. You can read more about from the link above and the information gathered to come to such a conclusion was done by a well known Google engineer, Benson Leung.

The raspberry Pi is a collection of small computer boards put together in a simplistic way to create the foundation of a computer system. The Raspberry Pi (also known as RPi) was released back in Feb of 2012 in the United Kingdom. The original intent of the RPi was to develop a low cost and simplistic computer which students could learn and develop.

The original model became far more popular than anticipated, and started selling outside its target market for uses such as robotics. It does not include peripherals (such as keyboards and mice) or even come inside a case. Literally a bare-bones product.

To give you an idea of the popularity, the RPi products have sold over 19 million units between its release in 2012 to the end of fiscal year 2018. This makes the RPi one of the best-selling computers in the world, although a computer with limited resources. Until now.

This week the Raspberry Pi Foundation has released the Pi 4. This is one hell of a great product. Check out these specifications:

  • A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3× performance)
  • 1GB, 2GB, or 4GB of LPDDR4 SDRAM
  • Full-throughput Gigabit Ethernet
  • Dual-band 802.11ac wireless networking
  • Bluetooth 5.0
  • Two USB 3.0 and two USB 2.0 ports
  • Dual monitor support, at resolutions up to 4K
  • VideoCore VI graphics, supporting OpenGL ES 3.x
  • 4Kp60 hardware decode of HEVC video
  • Complete compatibility with earlier Raspberry Pi products

In addition to the hardware improvements, the Raspberry Pi Foundation says

How To: Delete and Keep “System Volume Information” Folder Off Flash Drives

If you have found this post, chances are you are trying to delete and keep the “System Volume Information” folder off your flash drive.

UPDATE: Thank you to a reader sending in additional information, we now have a solution that is universal to all PCs. You will never get the “There’s a problem with this drive. Scan the drive now to fix it” message. To get this universal fix, scroll to the bottom of this message and look for “Updated Solution.”

I will venture to say, there are probably five reasons why you are trying to remove this directory (probably more):

  • You have a SmartTV or stereo in your car and the device is showing this folder, and often times, is the default start location to resume play, so you want to remove it.
  • A binary verification utility is failing and it shows this folder as the source of inconsistency.
  • The “Disk needs to be scanned and repaired message” keeps popping up when you remove a drive without using the Eject function from Windows.  You are now going crazy and want to stop that message forever.
  • A virus software utility is indicating this folder has a potential problem  (smart hackers could stick their code in here)
  • You are performing some kind of USB duplication process and this folder continues to be a problem, therefore you want to remove it.

Go ahead and skim down this article if you want to get right to the instructions.  For now, I’m going to take some time to explain what this folder is.  Knowledge is power, and maybe the reason for why it’s there, will deter you from wanting to delete it.

For any disk or storage device connected to Windows will have the “System Volume Information” folder.  This is a hidden system file, so if you don’t see it, that is the reason why.  You can see this file when you turn on “See Hidden Files” in your view properties settings.

The System Volume Information folder contains two files.  The two files are meant for setting restore points and indexing for what is on the drive.  Windows is trying to help you if and when you need to search the device for data.

The two files are the IndexerVolumeGuid and WPSettings.dat file.  The indexer file assigns a unique identifier (GUID, Global Unique ID) to the drive.  The indexing service examines the files so when you connect the drive to the computer in the future, Windows checks the identifier and knows which search database to associate with the drive.

WPSettings.dat file is used for Windows Phone’s Storage settings.  If you are dealing with a hard drive, this could be a good thing, if dealing with a flash drive, you don’t need it.  I haven’t met a person yet who backed up their phone data to a USB stick.

If you are still on the fence about whether you should remove this folder or not, think about this:  If you are dealing with a hard drive with an operating system, don’t delete it.  If you are dealing with mass storage drives, like a USB flash drive, you can remove it with little fear something bad will happen.

So how do you remove this folder?

How do you keep from this folder coming back?

The solution is a two-step process.  The first step will be disabling the indexing and thus, ask Windows not to put the folder on the drive.
