Flash drives and other forms of memory cards are irreplaceable tools for transferring and storing data. However, a common question we hear customers ask is, “Can my flash drive be used on any computer?” The answer is mostly yes, but with some important considerations.
Primarily, there are two factors that will qualify your flash drive to work on any computer. Your flash drive can work on any computer if it is formatted correctly and if the connector on the flash drive matches the computer’s port. In 2024, the most universal flash drive is a USB-A flash drive that is formatted to exFAT. What is exFAT? And why would USB-A make it more compatible? So, can your flash drive be used in any computer?
How to fix Flash Drive Compatibility issues with your Computer
File System Compatibility for Flash Drives
Chances are your flash drive is just formatted incorrectly for the system you are using. As a rule of thumb, exFAT is the most compatible formatting option. Using exFAT allows your flash drive to work with Windows, Mac, and Linux.
When you first get your flash drive, or when your flash drive is experiencing issues with compatibility connecting to your computer, start by formatting the drive. Remember, any time you format a memory card it wipes the storage and any data saved. Backup your important data before formatting. Flash Drives that are 32GB and under will often come with FAT32 formatting, whereas 64GB and larger flash drives will be formatted with exFAT.
Different File Format Options on Computers
Windows 10 and 11 as well as MacOS provide a number of formatting options. Below is a list of all the major file format options you will see with the two major operating systems. Take a look and see the specifics regarding each formatting option. Although FAT32 and exFAT are the most common, you may see the other versions in your experience as well.
FAT32
- It’s age has made it the default standard for off the shelf flash drives
- Maximum of 4GB for individual file size
- Maximum of 8TB partition sizes
- Compatible with practically any device with a USB port
NTFS
- Windows Only (Mac can read but not write)
- Default Windows file system
- Packed with features not included in FAT32 or exFAT
- Supports file permissions and security
- Offers a change journal
- Many other features
MacOS Extended Journaled
- The former Mac standard for HDDs
- Offers encrypted and case sensitive versions
exFAT
- No file size limitations like FAT32
- Mac and Windows both have Read/Write permissions
- Can work with Linux after installing the correct software
- Might not work on an older operating system
- The current (2024) MacOS standard for SSDs (MacOS 10.13 and later)
- Offers encrypted and case-sensitive versions
- Space sharing
- Snapshots
- Fast directory sizing
- Many other features
Physical Compatibility, Flash Drive to Computer
The second major compatibility determination for whether your flash drive will work on a particular computer is USB port compatibility. Most flash drives use USB-A connectors, which has become standard on most desktops and laptops. However, newer devices, especially laptops and tablets, may only have USB-C ports. If your flash drive is USB-A and the computer has only USB-C ports, you’ll need a USB-C adapter to connect the flash drive.
Moreover, flash drives come in USB 2.0 and USB 3.0 variants. While a USB 3.0, 3.1, and 3.2 flash drive can be used in a USB 2.0 port, it will operate at slower speeds. As a rule of thumb, the slowest connecting component determines the transfer speed. To take full advantage of the faster transfer speeds, ensure both the flash drive and the computer’s port are USB 3.0, 3.1, or 3.2 compatible.
Security and Software Restrictions
Finally, some computers, particularly those in corporate environments, may have security settings that restrict the use of external drives like flash drives or memory cards. The reason for this is some operating systems offer an auto-run feature. Malicious software writers can take advantage of this and breach the security of a business’ computer network. This security setting means that even if your flash drive is physically compatible and formatted correctly, you may need special permissions. Usually, this is something you have been made aware of in training, but it might be worth talking to your administrator.
