1. Sd Mmc Slot Not Working Remotely
2. Sd Mmc Card

I just bought a brand new Nikon D3400 and a brand new SanDisk SDXC SD card. When I insert the SD card into the slot it tells me that it cannot read the card and that it might be damaged, but if I insert it into my computer it reads it just fine. I have tried formatting it on my computer and it still doesn't read the card. How to get your SD card reader to work after Windows 10 upgradeI just wanted to share this very simple way of getting your SD card reader to work after a win. Everything works fine so far except the computer Memory Card Slot (SD/SDHC/SDXC/MMC) does not recognize any of my personal SD/SDHC Cards. All the SD/SDHC cards are valid and working due to the fact that my two older computers recognize the same identical SD/SDHC cards with no problem that I am using on the Lenovo 110-151BR (Model 80TT) Computer.

If your SD card doesn’t appear in Windows File Explorer when you plug it into your PC’s card reader, don’t despair. This is a common Windows problem, and despite being very frustrating, it’s usually very easy to fix.

Below is a list of the fixes that have worked for other Windows users. Start at the top of the list and work your way down until you find the fix that works for you.

Method 1: Update your drivers
Method 2: Clean your SD card & reader
Method 3: Check if your card reader is disabled
Method 4: Test your SD card in another PC
Method 5: Disable then enable card reader (from other users)

Method 1: Update your drivers

The most common cause of an unrecognized SD card is a faulty, incorrect or outdated card reader driver. So the first thing you should do it check that your drivers are in good health. You can do this either manually or automatically:

Manual driver update – You can update your drivers manually by going to the manufacturer’s website and searching for the most recent correct driver. Note that for some drivers, you may need to try both the manufacturer of your PC and also the manufacturer of the card reader itself. If you don’t have the time, patience or computer skills to update your drivers manually, you can, instead, do it automatically with Driver Easy.

Automatic driver update – Driver Easy will automatically recognize your system and find the correct driver for your card reader. You don’t need to know exactly what system your computer is running or who your card reader’s manufacturer. Nor do you need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing. You can simply update your card reader driver (all your drivers, actually!) automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks, and you get full support and a 30-day money back guarantee:

1)Downloadand install Driver Easy.

2) Run Driver Easy and clickScan Nowbutton. Driver Easy will then scan your computer and detect any problem drivers.

3) Click theUpdate button next to all flagged devices to automatically download and install the correct version of their drivers (you can do this with the FREE version). Pay close attention to whether your card reader appears in the list.

Or clickUpdate All to automatically download and install the correct version ofallthe drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

If your card still isn’t working after updating your drivers, move onto Method 2.

Method 2: Clean your SD card & reader

Another very common cause of an unrecognized SD card is a very simple one: a dirty SD card or a dusty card reader. Either will cause a poor contact between card and reader.

So the second thing you should do is give your card a clean, and remove any dust from the reader, then try the card again.

• To clean your card, dip a cotton cloth in a little alcohol or water, and lightly wipe the dirty area, paying particular attention to the metal contacts.
• To clean your reader, use a compressed air device to blow the dust out of the reader. Alternatively, you can buy contact cleaner on Amazon, which you can use to clean the reader.

If the card still doesn’t work, move onto Method 3.

Method 3: Check if your card reader is disabled

If you’ve tried methods 1 and 2, and your PC still isn’t recognizing your SD card, it’s possible your card reader is turned off in your BIOS.

To check, restart your PC, and at the splash screen (the first screen you see after restarting), look for an instruction that tells you to press a certain key on your keyboard to enter your “BIOS” or “Settings” (e.g. F2 or Delete). Every motherboard manufacturer has their own unique BIOS with its own keyboard shortcut, so we can’t say exactly which key to press to get in.

Likewise all manufacturers organize their BIOS settings their own way; there’s no standard way of doing it. So we can’t tell you exactly what setting to change, and how to find that setting. But once you’re in the BIOS, it shouldn’t be too hard to find the ‘on/off’ switch for your card reader. Just look for a section related to devices or storage, and within that section look for something like “SD Reader” or “Card Reader”. Enable that setting if it’s not already enabled, then save and exit the BIOS. (Be sure to save as you exit. Some manufacturers make it very easy to leave the BIOS without saving your changes, and if you do, you won’t have changed anything.)

Once your computer has restarted and you’ve logged into Windows, test your card again. If it’s still not recognized, move onto Method 4.

Method 4: Test your SD card in another PC

If your SD card is faulty, your PC won’t recognize it. To check, you’ll need to locate another PC with a card reader, and test your SD card in that computer, to see if it works.

If your SD card doesn’t work in the other PC either, it’s probably faulty, and you’ll need to replace it.

If it does work in the other computer, then it’s not a faulty card, but it may be that your card reader is faulty.

Method 5: Disable then enable card reader (from other users)

Thanks Alan Darlington for sharing this method, which has worked for many users. So if your SD card is still not showing up on your PC, try this method.

Quote Alan Darlington’s words:

“Easy solution for me: ASUS X551C, Win10, 16G SD:
Go to device manager as above — when I do it there is no SD Host Adapters but there is Memory Technology Devices under which there is RealteK PCIE Card reader. Select this then click Driver then on the Disable, acknowledge the popup, then back at the driver screen click on the Enable and its popup — the SD card now appears as it did previously & is accessable.
Don’t know why this works but it did for me.”

If you’re not sure how to do that, refer steps below:

1) On your keyboard, press the Win+R (Windows logo key and R key) at the same time to invoke the run box.

2) Type devmgmt.msc in the run box and click OK.

3) Expand category “Memory Technology Devices“. Double-click the card reader (In Alan’s case, it’s RealteK PCIE CardaReader. In your case, it may be different.) to open

4) Go to Driver tab. Click Disable Device.

5) When prompted to disable the device, click Yes.

6) Double-click the card reader to open the Properties windows. Click Enable Device to re-enable the device.

Option 1: Check your Finder desktop and sidebar preferences

On Mac, you can choose to show connected items on the desktop, including hard disks, external disks, connected servers. Therefore, if you don't set the preference to show your SD card on the desktop, it won't appear on Mac. Easy to understand, huh? Let's see how to show SD card on the desktop?

• 1. Go to Finder > Preferences > General, make sure the 'External disks' option is ticked. This will make the SD card show up on the Desktop.
• 2. Select the Sidebar tab on the top, make sure the External disks option under Locations is also ticked.

Option 2: Restart your Mac

Whether the issue is related to networking, graphics, slow performance, faulty programs or macOS issue, a simple reboot can fix a computer issue 80-90% of the time. It also works when external drives are not recognized by macOS.

When your SD card is not reading on Mac, you can try to remove the SD card and then switch off the Mac. Leave it for a few minutes, turn it back on, and try again.

Option 3: Check if SD card reader is not working

To access an SD card, you usually need a card reader. When your SD card won't work on Mac, the first thing to check is whether the card reader is working or not. It doesn't matter that you access the SD card by the built-in slot on your Mac or a third-party one. Simply follow these steps to check if the SD card reader is recognized or not.

• 1. Simply click Apple Menu > About This Mac > System Report.
• 2. Find Card Reader under the Hardware list.
• 3. If the card reader works, you can see its Vendor ID, Serial Number, and some other product information. When your SD card is inserted, it should also be listed at the right with specifications.

If unfortunately, the card reader is not recognized, it might be an SD card hardware issue. For a broken slot built-in your MacBook, you need to send it to a local Apple store for repair service. Instead, for a malfunctioned external SD card reader, you can simply replace it with a new one.

Option 4: Check for the connection issue

If the card reader is working fine, then you should check the connections. First of all, make sure you insert your SD card properly. (The metal contacts must face down and point toward your Mac). Secondly, you can test your SD card on a different card reader. If you can access the SD card then, it should be the card reader that has a problem.

Option 5: Check if SD card is locked

Another case for SD card not working on Mac is that the SD card is write protected. When you try to write content to the locked SD card, you cannot modify the files on the locked SD card. To work on the SD card again, you need to safely eject the SD card and adjust the lock slider tab on the card to unlock the card. Then you can access the SD card after you reinsert it to the slot.

Option 6: Insert your SD card in different devices

Another very effective strategy that you can implement is to insert the SD card in different devices, such as phones, digital cameras, or other computers. For instance, you can remove the SD card from your Mac and insert it into your Android phone. If your SD card is still not detected or working on a phone, the card might be damaged or you need to try the following solutions.

Option 7: Reset NVRAM/PRAM

NVRAM/PRAM is a chip in Intel-based Macs used to remember the setting for your computer, including sound volume, display resolution, startup disk selection, time zone, peripheral devices and more. It's worth resetting whenever you find your computer's hardware acting in unexpected ways.

To reset NVRAM, you should shut down your Mac, then turn it on and immediately press and hold Option + Command + P + R. Keep holding down those keys for about 20 seconds. Then release the keys and allow your Mac to continue starting normally.

Option 8: Mount SD card in Disk Utility

After resetting NVRAM/PRAM, your SD card is still not recognized on Mac. You should go to Disk Utility again and see whether the SD card is listed. If you can see your SD card in Disk Utility, but the SD card is greyed out, that means the SD card is not mounting. Simply select the Mount option to see if the SD card will be mounted in Finder and desktop.

Option 9: Update the drivers on Mac

If the issue still exists, you can check whether the drivers on your Mac is renewed. If your Mac drivers are outdated, your SD card or other external hard drives will not be recognized by your Mac. Here are steps to update drives on Mac:

1. If you have upgraded to macOS Mojave, you should choose System Preferences from the Apple menu, then click Software Update to check for updates. If any updates are available, click Update Now to install them.

2. If you are using earlier macOS versions, just launch the Mac App Store, click the Update tab on the top and then choose the 'Update All'.

Option 12: Send SD card to an expert for reparation
