Cannot Format a USB GPT Protective Partition

Sometimes you will connect a USB to the PC and get an error message saying the drive has a GPT Protective Partition and you cannot format the drive. Here is the fix to resolve the issue:

First, what is a GPT USB stick? The GUID Partition Table (GPT) is the successor to the Master Boot Record. The MBR was created by IBM back in the early 90s. The problem with MBR is the limitation to partition table sizes which is 2 Terabytes.

Since there are no 2T USB flash drives (at the time of this post), there is no need to use GPT as your partition table.

Removing the GPT Protected Partition can be accomplished through the Windows Diskpart program.

  • Determine the Disk Number for the USB GPT-protected drive. To do this, perform the following:
  1. Right-click on (My) Computer.
  2. Choose Manage.
  3. Select Disk Management (listed under Storage).
  4. Look for the drive that is identified as GPT and note the Disk number (such as Disk 1).
Format USB GPT Protected Partition
  • Now, open a Command Window. From the command prompt, type diskpart and press Enter.
  • The diskpart prompt will open.
  • From the diskpart prompt, type list disk and press Enter. A list of disks will appear in a text format. You will return to the diskpart prompt.
  • From the diskpart prompt, type select disk disknumber (in this example from the screen shot above, you would type select disk 1)and press Enter. A message appears saying that the disk is selected. You will return to the diskpart prompt.
  • From the diskpart prompt, type clean and press Enter. At this point the drive’s partition and signature a removed. You will return to the diskpart prompt.
  • From the diskpart prompt, type exit and press Enter. Type exit once more to close the Command Window.

How To: Make a USB Read Only

There are two ways to make a USB stick read only. One way is a universal solution and is 100% permanent, the other way is PC specific and a good deterrent. When we say 100% permanent, this means the USB stick is read only (write protected) on all computers, whether it be a Mac, PC, Linux, etc type computer, the USB is read only and the status cannot be changed. The other method flags a USB device to be read only in relationship to the PC it is connected to so that whenever that USB stick is connected to that computer, it makes the USB read only and blocks all write commands to the device.

Most times an IT manager or content owner wants the USB stick to be read only so the files cannot be deleted or formatted off the drive. Another reason for making a USB read only is for the original files to remain the same and blocks the ability for files to be changed or manipulated. Finally, it’s smart to have USBs read only so that virus’ don’t jump onto the drive and possibly spread to other computers.

Let us start with the less permanent way because it’s easier to do and doesn’t require any specific hardware. You will need a Windows7 machine or higher. The Windows7 machine will have DiskPart utility which allows us to perform all sorts of cool things to flash drives, like setting write protection.

  • Connect the USB to your Windows computer.
  • To begin, go to your Windows Start and in the Search Field type “cmd”

This will run your Command prompt.

  • Next, you will want to get to the C root of the Command prompt and if you are signed in as a user you can simply type cd\ this will get you back to the root of the C drive.
  • Type DISKPART
  • Type LIST DISK

Now you will need to find the USB stick connected to your PC. Most likely it’s DISK 1

Our Answer to a Smartphone / Tablet Dock Charging Station

With the iPhone in its 8th iteration of the product and most likely you have some older models laying around. Those older models can be put to use, but chances are, you don’t keep them charged up. So after a couple of days without connection, they are dead. I currently use an older iPhone to stream my music at work. I don’t stream from my phone, because I always seem to get disconnect to the Bluetooth speakers after I take a call. USB charge dock station This is why I like the 10 port charging station from USBFever. It’s got a logical design for holding ten devices. With the USB ports on the bottom, it keeps the plugs from hanging off the wall. Just above the USB ports are hollow channels you can bundle up the USB cable and stash it away. On top are vertical channels to hold your iPhone, iPad, Smartphone or tablet. The vertical channels are tall enough the devices will sit sturdy and proper. Finally, the design includes a good balance of power output for the devices. There are a total of 10 USB ports. Eight of which push out a 2.5amp power supply and the remaining two are 1amp. This means the charging dock station will power the tablets as well as the larger iPhone and Samsung product while you can leave the smaller phones to the 1amp channels. The default color is Continue Reading

How Flash Memory Works

This is a great video that explains how flash memory works. Granted, the video is very technical but does work through the concept of reading and writing data to flash. So if you have the 17 minutes to use, I suggest giving this a watch. The video does cover SLC, MLC and TLC memory and how each of these technologies read and write with the different layers of a floating gate device like NAND. Source: YouTube. Continue Reading
