| APFS | Full (Read & Write) | No (Requires third-party software) | Solid-State Drives (SSDs) | Mac-only workflows, Time Machine backups, and maximum file transfer speeds. |
| exFAT | Full (Read & Write) | Full (Read & Write) | SSDs & Flash Drives | Users who constantly swap their Samsung T7 between Mac and PC. |
| Mac OS Extended(HFS+) | Full (Read & Write) | No (Read-only with legacy tools) | Mechanical Hard Drives (HDDs) | Older Macs running macOS 10.12 (Sierra) or earlier. |
| FAT32 | Full (Read & Write) | Full (Read & Write) | Small USB Drives (under 32 GB) | Legacy devices only. Limited by a strict 4 GB maximum single-file size limit. |
Different Ways You Can Format Samsung T7 for Mac
Here are two methods to format a Samsung T7 external drive on a Mac. In the example, we will format the Samsung T7 to APFS for optimal performance with a Mac.
Before you start formatting your Samsung T7 on Mac, plug in your drive to your USB port and ensure that the drive is visible on your device. If it's not visible, consider looking into solutions for external SSD not showing up on Mac.
Way 1. Format Samsung T7 for Mac Using Disk Utility
Disk Utility is a built-in macOS application that helps manage drives and partitions on your Mac. It's a simple and effective way to help you format your Samsung T7 SSD for Mac. Here are the steps you should follow:
- Launch Disk Utility
Connect your Samsung T7 to your Mac. Open Finder, navigate to Applications > Utilities, and double-click Disk Utility.
- Reveal All Physical Devices
By default, macOS hides raw drive hardware. Click the View dropdown icon in the top-left corner of the window and select Show All Devices. - Select the Root Drive Entry
Look at the left-hand sidebar. Select the first-level parent entry for your drive (e.g., *Samsung SSD T7 Media) rather than the indented volume partition name below it.
- Initialize the Erase Screen
With the root hardware drive highlighted, click the Erase button located in the top action toolbar. A setup window will overlay on your screen.
- Configure Scheme to Unhide APFS
Type a name for your SSD. Next, look at the Scheme dropdown field and select GUID Partition Map first. Choosing this partition scheme instantly unlocks APFS in the format field. - Select APFS and Format
Click the Format dropdown selection field and choose APFS (or exFAT if you require cross-platform support). Click Erase to run the formatting process.
Your Samsung T7 external drive is now formatted to APFS for use with your Mac. You can begin transferring files and using the drive as needed.
Way 2. Format Samsung T7 for Mac Using The Terminal
Formatting your Samsung T7 SSD for Mac using Terminal is an alternative method for those who prefer using command-line interfaces. Terminal is a built-in macOS application that allows you to execute commands directly to your system. Here's how to format Samsung T7 to APFS using Terminal:
- In Finder, click on Applications, then Utilities, and double-click Terminal.
- In the Terminal window, type the following command to list all connected drives and their identifiers:
diskutil list
- Locate your Samsung T7 external drive in the list and note its identifier (e.g., disk2).
- To format the drive, type the following command, replacing "X" with the identifier noted in the previous step:
sudo diskutil eraseDisk APFS "SamsungT7" GPT /dev/diskX.
(This command will format the Samsung T7 drive as APFS with the name SamsungT7 and using the GUID Partition Table (GPT) scheme.
If you prefer to use Mac OS Extended (Journaled) instead of APFS, replace APFS with JHFS+ in the command.) - Press Enter to execute the command. You will be prompted to enter your administrator password.
- Enter your password and press Enter again. The Terminal will format your Samsung T7 drive according to your chosen settings.
- Once the formatting is complete, a success message will appear in Terminal.
Your Samsung T7 external drive is now formatted for use with your Mac. You can begin transferring files and using the drive as needed.
How To Recover Data From Samsung T7 if You Lose Files After the Formatting
If you've accidentally formatted your Samsung T7 without backing up your files or the drive was read-only, and you couldn't extract the files, don't worry. A professional data recovery tool can get your data back even after formatting, and Wondershare Recoverit is a highly recommended option for hard drive data recovery.
🔍 Recovery Potential for Common Samsung T7 SSD Storage Issues
External SSD storage layouts behave differently than mechanical drives. When a drive format occurs, the file pointers are broken, but the raw data code blocks remain intact until overwritten. Wondershare Recoverit targets these blocks directly:
| External SSD Issue | Primary Risk Feature | Recoverit Deep Scan Strategy | Success Rate |
| Accidental Quick Format | File allocation maps erased | Rebuilds volume structures via raw file signatures. | Highly Successful |
| Drive Disconnection Mid-Format | Partition map becomes corrupt or unreadable | Scans raw storage sectors directly, ignoring system errors. | Highly Successful |
| Read-Only / Permissions Locked | Drive locked by alternative operating systems | Extracts inaccessible files directly to your native Mac storage drive. | Highly Successful |
Here's how you can do this using Wondershare Recoverit:
- Download Wondershare Recoverit for Mac from the official website and install and launch the program.
- Click on Hard Drives and Locations and select your Samsung T7.
- Wondershare Recoverit will automatically scan the drive for lost files.
- Select the files you want to recover and preview them. Click on Recover when you're ready.
