![]() Whatever happens, there are always ways to deal with it. But what if it’s not there? There can be many reasons for a Mac not reading a hard drive — poor connection, faulty cable or, in the worst-case scenario, corrupt hard drive data. I will have to test se.When you plug in a hard drive into your Mac, you expect it to pop up in Locations in Finder — next to your remote disk and the computer itself. This thing is amazing on my mac. Check for office updates macThen go to Sidebar and check Hard disks and External disks there as well. Make sure you tick the boxes next to External disks and Hard disks. Follow Preferences → General → Show these items on the desktop. To fix that, go to Finder and click on the Finder button in the menu bar at the top of the screen. However, you could still check your preferences — just in case.Your settings might not be set to display external hard drives on your desktop. Don’t forget to have your Mac connected to the charger. Check that your USB cable is delivering enough power to the hard drive and, if need be, swap to a more powerful connector or to a different USB port on your Mac.You could also use an external power source or even a self-powered USB hub — adding its power to the power of your Mac might resolve the issue. Normally, a device requires up to 500 mA, which can be provided by a standard USB 1.0 or 2.0.However, if your hard drive needs a stronger power output, it may work slower than expected or not connect at all. However, it’s almost always effective and isn’t actually that bad if you carefully follow the steps: Use TerminalFor average users, the Terminal app is a last-resort solution because they tend to find it complicated. Try using another Mac or Windows device — if it only works on a PC, it’s likely that your hardware is not formatted to be launched on a MacOS device. Then you can eject it by typing in diskutil eject disk_, with your drive’s assigned digit in place of the underscore If your system recognises the drive, this action should reveal the information about your drive. Type in another command — diskutil info disk_, with the digit of the external disk that you’re interested in in place of the underscore A list of your disks will appear — search for a line with /dev/disk_ (external, physical) — the underscore signifies a digit assigned to your disk’s identifier Type in diskutil list - a command that extracts information from the system to analyse any volumes and drives attached to your Mac Choose A Samsung Ssd For My Pro Password When PromptedTo make changes to the list of apps that have the permission, click on the lock symbol in the bottom left corner of the window and enter your password when prompted Scroll down the menu on the left until you see Full Disk Access Quit Terminal and go to the Apple Menu → System Preferences → Security and Privacy → Privacy It locks down certain areas of the system and only relieves the lockdown during updates.To fix this error, you need to grant Terminal full disk access: This is not a software bug — it occurs due to additional System Integrity Protection security measures that Apple introduced in the newer versions of the operating system. It should now be able to mount normallyIf you’re running MacOS Mojave or Catalina, you might come across the “Operation not permitted” error when entering a Terminal command. The sidebar on the left will display any external drives — you should be able to view your hard drive there Go to Applications → Utilities → Disk Utility → View → Show All Devices It can help to access and repair some disk issues by checking partition Macs and performing additional checks across the system. Once you’ve added Terminal, click on the padlock again to disable access to editing.Disk Utility often becomes the ultimate fix for a lot of Mac problems, including those related to external drives. Look for Terminal in Applications → Utilities FAT32 and exFAT are recognised by both Mac and Windows devices. If you can’t see a volume list, your Mac can’t access the drive at all and you won’t be able to mount itMacs use HFS+ or APFS format, whereas Windows computers employ NTFS. If the drive has been mounted, there will be an option to unmount the device. Bear in mind — all of your hard drive’s contents will be erased during the processIf you can’t sacrifice the data on the disk, you can reformat it using a Windows device: In the menu bar at the top of the window, click on Erase and choose the format compatible with your Mac device Click on it to open the drive’s information You should be able to see the external hard drive under the External heading in the sidebar on the left. Go to Applications → Utilities → Disk Utility Plug in the connector of your device slowly into the port of your Mac — this ensures proper initiation Click Start to initiate formatting. Name your hard drive in the Volume label window Choose a format that’s compatible with both Mac and Windows devices — exFAT is the most modern and preferred one Right-click on the drive’s icon and choose Format from the drop-down menu Copy all of the drive’s contents into a separate folder on the PC If you right-click on the device’s icon, the First Aid bar will show up in a drop-down menu. It will then attempt to repair them. It checks the disk for any errors that could potentially cause the external hard drive not mounting on your Mac. Make sure to transfer the data back to the disk from the folder you’d createdRegardless, you can always run the First Aid program. If, by chance, they contain important information, make sure they’re not corrupted.If the First Aid process fails, you have two options: run the program again and repair the disk, or to back up all the data you possibly can, change the format of the disk and reinstall your current operating system. The list of affected files will be displayed in the DamagedFiles folder in your drive — you should delete them. If the program discovers an “Overlapped extent allocation” error, it’s likely that some of your files are corrupted. As a result of the screening, you will be advised on any errors that your Mac finds on the disk. Resetting it is easy and generally harmless, although it might mean that you’ll have to reset any basic custom settings you have on your laptop. It ensures such small details as keeping your time zone consistent or keeping the volume muted when restarting your Mac.NVRAM bugs are the source of many glitches, including a USB flash drive not showing up. Mac’s firmware can primarily access this information, such as before it starts booting when you restart it. Reset NVRAMNonvolatile random-access memory (NVRAM) stores local settings such as volume, screen resolution, and hard drive information. The power contacts in your USB connector are designed to make contact with the USB port first. This is due to a design flaw in the power-up sequence of some of the USB drives. Try Plugging It In SlowlyA strange feature regarding all USB cables — sometimes it may connect and function better if you plug it in more slowly. This causes your Mac to restart again — when you hear the startup sound for the second time, you can let go of the keysOn newer Macs, there’s no need to even restart the computer — just press down the combination for 20-30 seconds and your NVRAM will be reset. ![]()
