Your Mac probably doesn't recognize the Thkailar drive's file system

Thkailar thumb drives come formatted in NTFS (Windows format) or exFAT by default, depending on the model. macOS can read exFAT without any extra software, but it cannot write to NTFS drives, and older Macs sometimes struggle to recognize NTFS at all. If your Mac doesn't show the drive on the desktop or in Finder, the file system mismatch is usually the culprit.

The second common reason is a USB connection issue — either the port on your Mac isn't working, the cable is damaged, or the drive itself has a loose connection. A third possibility is that your Mac is running an older version of macOS that doesn't support the drive's format or USB standard.

Before you troubleshoot, check whether the drive shows up anywhere at all. Plug it in, wait five seconds, then open Finder and look in the sidebar under "Locations". If you see the drive listed there, the connection is working — the problem is file system access. If you don't see it anywhere, the drive isn't being recognized at all.

Key Takeaways

  • Thkailar drives formatted in NTFS will not appear on your Mac desktop or in Finder, but exFAT drives usually will.
  • You can reformat the drive to exFAT or Mac OS Extended (Journaled) to make it work with your Mac, but this erases everything on it.
  • If the drive doesn't show up in Finder at all, try a different USB port on your Mac and a different cable before assuming the drive is broken.
  • Older Macs running macOS 10.12 or earlier may need third-party software to read NTFS drives, though this is rare.

Check which USB port and cable are actually working

Before you reformat anything, rule out a simple hardware problem. Unplug the Thkailar drive and try a different USB port on your Mac. If your Mac has multiple ports, test at least two — USB-A ports on older Macs, or USB-C ports on newer ones. Some ports stop working after years of use, and you might have a dead one without realizing it.

Then try a different cable if you have one. The cable that came with the Thkailar drive could be damaged internally even if it looks fine. If you have another USB drive at home, plug that into the same port where you tried the Thkailar drive. If the other drive works, your Mac's port is fine and the problem is either the Thkailar drive itself or its cable. If the other drive also doesn't work, that port is the problem — try a different one.

Reformat the drive to exFAT if you want to keep using it with both Mac and Windows

If the drive shows up in Finder but you can't open files on it, or if it shows up but appears empty, reformatting will usually fix it. Warning: reformatting erases everything on the drive. Back up any files you need before you start.

Plug in the Thkailar drive and open Disk Utility (search for it in Spotlight by pressing Command + Space, typing "Disk Utility", and pressing Enter). In the left sidebar, you should see your drive listed by name. Click it once to select it, then click the "Erase" button at the top.

A dialog box will appear asking for a name and format. Name it whatever you want. For the format, choose exFAT if you plan to use the drive on both Mac and Windows computers. Choose Mac OS Extended (Journaled) if you only need it to work with Macs. Click "Erase" and wait for the process to finish — it usually takes less than a minute.

Once it's done, the drive will mount on your desktop and in Finder. You can now copy files to it from your Mac.

Reformat to Mac OS Extended if you only use Apple devices

If you never plan to use the Thkailar drive with Windows or Android devices, formatting it as Mac OS Extended (Journaled) gives you better performance and reliability on your Mac. The steps are identical to the exFAT process above — open Disk Utility, select the drive, click Erase, and choose Mac OS Extended (Journaled) from the format dropdown.

This format is optimized for macOS and handles large files more efficiently than exFAT. The tradeoff is that Windows computers won't be able to read it without third-party software, and most Android phones won't recognize it at all.

Try a different Mac or computer to test the drive itself

If the drive doesn't show up in Finder on your Mac even after trying multiple ports and cables, the drive itself might be broken. Before you assume that, test it on another computer if you have access to one — a friend's Mac, a Windows PC, or even a Linux computer. If the drive works on another machine, the problem is specific to your Mac or its USB ports.

If the drive doesn't work on any computer, it's likely a hardware failure inside the drive. Thkailar drives come with a limited warranty; check the documentation that came with it or look for a serial number on the drive itself to see if you can contact the manufacturer about a replacement.

Update your Mac if it's running very old software

Macs running macOS 10.12 (Sierra) or earlier sometimes have trouble recognizing USB drives formatted in certain ways. If your Mac is that old, check for software updates by clicking the Apple menu in the top-left corner, selecting "System Preferences" (or "System Settings" on newer Macs), and looking for an "Update" or "Software Update" option.

If your Mac is too old to run a newer version of macOS, you can still use the Thkailar drive by reformatting it to exFAT, which older Macs handle more reliably than NTFS.

Frequently Asked Questions

Can I use the Thkailar drive on both Mac and Windows without reformatting?

If it's already formatted in exFAT, yes — both systems can read and write to exFAT drives. If it's formatted in NTFS, your Mac can't write to it, and you'll need to reformat it to exFAT to make it work for both systems.

What's the difference between exFAT and Mac OS Extended?

exFAT works on Mac, Windows, and most Android devices, but it's slower with very large files. Mac OS Extended is faster on Macs but only works with Apple devices. Choose exFAT if you share the drive between systems, or Mac OS Extended if you only use it with Macs.

Will reformatting the drive damage it?

No. Reformatting just erases the files and changes how the drive organizes data. It doesn't harm the drive itself. The only risk is losing files if you don't back them up first.

What if Disk Utility doesn't show my Thkailar drive at all?

If the drive doesn't appear in Disk Utility, it's not being recognized by your Mac at the hardware level. Try a different USB port and cable first. If it still doesn't show up, the drive or its connection to your Mac is likely broken.
