Have you ever encounter a situation where you need to format your USB drive? Ever confused about what on earth does “format” means? And what are the differences between different file systems? If you indeed have these questions on your mind, then read this post, maybe you will find out the answers to them.

 

What is Formatting?

Well, first of all, let’s make out what this “format” thing is. Well, to format a drive, no matter it is hard disk, floppy disk, flash drive, means to prepare it for initial use by deleting all of the files, and data on the drive and setting up a file system.

The most popular file system is to support Windows is NTFS, but FAT32 is also often used. The differences between them will in included in later part.

 

You Might Need Format Your USB Drive If:

1. Your USB has been virus attacked and you need to clear the viruses and regain access to the drive.

2. You have upgraded to storage device with bigger capacity and faster I/O speed, the drive will be passed on to family members and you don’t want them to see what was in it.

3. The write operation was interrupted before completion, and the next time you plug the drive, it says it need to be formatted before use.

4. You have a new PC or something that needs to format the USB drive to recognize it.

 

What are the Differences between NTFS and FAT32?

NTFS is the current file system used by Windows. Compared to FAT32, it has the following advantages:

1. It could read/write files larger than 4 GB and up to maximum partition size.

2. It could create partition larger than 32 GB.

3. Being able to compress files and save disk space, also, less fragmentation.

4. It allows more clusters on larger drives, which means less wasted space.

5. It offers permission that allows us to determine which user can access to your files and folders.

Well, even though NTFS has so many advantages over FAT32, there is something that the latter one is good at:

1. FAT32 is compatible with virtually all operating system.

2. It takes up less space on USB drive.

3. It has faster writing speed and less memory usage.

That’s about it, choose the file system you like when formatting your USB drive.

When you were trying to open a folder or to cut/delete something in your USB drive or memory card on computer, have you ever encountered the pop-out window that says,”This disk is write-protected. Remove the write protection or get a new disk.”? Well, write protection is a common error occurs mostly due to immediate unplugging of the drive or memory card when the transfer is done or half-done. Though in some of the case it was caused by left the write protection switch on. Then how to fix this? How to remove the write protection? Here I provide some methods that might be helpful, read on.

Method 1. Remove Write Protection by Checking your Lock Switch.

Some USB drives or memory cards have the write protection switch now, which protects the drive from being formatted or written. In some cases, the reason why we encounter the write protection error is that we left the switch on the lock  position. So when the error pops up, just unplug the USB drive or memory card and check if it is locked. (There are other USB drive brands that are well-received, like HP USB drive. )

sd card write protectionIf it is indeed locked, switch it to the unlock position, then the write protection should be removed.  however, if your USB drive or memory card doesn’t have the lock switch or the error remains with the switch is off, it could have been the problem with the file system. Try the following method to remove the protection.

Method 2. Remove Write Protection by Modifying Registry Key

Hey, don’t be intimidated by the phrase “registry key”, it’s not as difficult as it sounds. Just follow the steps below, you will find removing write protection is pretty easy.

1. Press Windows+R to open run.exe, then type “regedit” to open Registry Editor.

2. Navigate to the following path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

3. Double click the WriteProtect, change the value from 1 to 0, and save the change.

change writeprotect

4. Close registry editor and reboot your PC, then your write-protected USB drive or memory card should be ready.

What If There is NO StorageDevicePolicies?

Some of you may find that there is no StorageDevicePolicies under the Control, then what to do? Then answer is simple, if there is no such a value, create one then.

1. Under the Control folder,  right click the white space, hit New->Key, and name the folder “StorageDevicePolicies”.

01

2. Double click to enter the new folder, then right click on the white space, hit New-> DWORD, name it “WriteProtect”.

3. Set the value data to 0, save the change and reboot your computer.

By this step, the write protection should be removed, if not. Let’s activate the great tool Command Prompt to kill it.

Method 3. Remove Write Protection By Using Command Prompt

The command we are using in this method is diskpart, some of you may think that command prompt is way to difficult, no worries, here is a clear and detailed guide for you.

1. Once again, press Windows+R to open run.exe, then type “cmd” this time.

2. When the command prompt pops out, type “diskpart” and enter.

3. Then type “list disk” and enter.

4. When the list of your disks shows up, figure out which one is your USB drive or memory card by its capacity, and type “select disk x(x being the number of your drive)”.

5. Then type attribute disk clear readonly. When it’s done, then the write protection should be removed.

By now you should be able to cut and delete files on your USB drive. If still it’s not working, then there is no much thing we can do, it’s time to get a new USB drive or memory card.

Also, if your USB drive became writable and you accidentally deleted some files or formatted it, please use Card Data Recovery to recover the lost files.

Removing USB stick safely is always a highly recommended action before unplugging a USB device. However, do you really need to safely remove USB stick? Is there is also a good chance that you can unplugged a USB device without using this option and nothing goes wrong.

In fact, Windows itself tells that you don’t have to use the Safely Remove Hardware option if you use certain settings – the default settings. Windows also provide alternative option: Quick removal which you can disables write catching on the device and in Windows, but you can disconnect the device safely without using the Safely Remove Hardware notification icon.

quick-removal

You can access this setting from the device manager – open the Start menu, type Device Manager, and press Enter to launch it. Expand the Disk drives section in the Device Manager, right-click your device, and select Properties. Finally, select the Policies tab in the Properties window. Here you can find the option – Quick Removal. It means that you can unplug your USB device without safely removing it.

However, there is one thing you need to keep in mind that is no matter which option you select, you should never unplug your USB device while data is being written to it such as when you are moving files to it or you’re saving a file to it, because unplugging a USB disk is in-use will cause data corruption or data lost.

Sometimes the USB device doesn’t appear to be in-use but it is still in-use as a program in the background may be writing to the drive. In this occasion if you quick remove your USB disk will cause data corruption.

So if your USB stick doesn’t appear to be in-use, you can probably unplug it without any data corruption occurring – however, to be safe, it’s still a good idea to use the Safely Remove Hardware option.

P.S.: Unfortunately lost data from USB disk? You can turn to Card Data Recovery for help.

USB users know that we need to use the safely remove hardware icon before unplugging a USB device. It is always a good practice to safely remove your USB flash drive before unplugging it from your computer.

Why We Need to Remove a USB drive from the Computer Safely?

It is highly recommended to safely remove USB drive. If you simply pull an external drive out of a running computer, you’re asking for trouble. You might lose files, crash applications, or even ruin everything on the computer.

Note: If you lost data on your USB drive due to simple pull it out of your computer, turn to Card Data Recovery to recover your lost data.

How to Remove a USB drive from the Computer Safely?

1. Close all files you accessed from the USB drive. Don’t forget to save your files before closing the files.

2. Right-click the “USB” icon marked with a checkmark. From the pop-up menu, click “Safely Remove Hardware.”

3. Select the USB flash drive you want to unplug then click the “Stop” button. Click your USB drive, and then click “OK.” The “Safe to Remove Hardware” window tells you that it’s safe to remove the hardware.

But sometimes, Windows will tell you that “This device is currently in use”.

At this time, you need to check the properties on the drive to see if the drive is being indexed. Open Windows Explorer and right click on the external hard drive. On the first Property Windows, make sure the “Allow files on this drive to have contents indexed in addition to file properties.” is not checked. If it is, remove the check mark and once you click on “Apply”, ensure it removes indexing from all folders, sub-folders, etc. This is usually the reason you cannot remove an external hard drive using the safe remove.

Or you can simply shut down your computer–not hibernate it or put it in sleep mode–but shut it down completely. Then you can safely remove your USB flash drive.

Now I believe you have a clear idea about how to remove your USB flash drive safely. So stop simply pulling USB drive out of a running computer.
