cannot format micro sd, believe me, i tried everything

This is eerie, I have the exact same card in the exact same phone with the exact same problem. I cannot delete any information from the card without it restoring itself, I also cannot add files bigger than a picture to it without it becoming corrupted. I would also appreciate some assistance. I have mailed Sandisk about it and hopefully I will get a response but who knows.

Any update from sandisk regarding this issue. I also encountered the same issue. This is my 2nd 64gb sandisk class 10 which faced the same issue. The 1st one was replaced as it is under warranty. Now the 2nd has no warranty anymore. Please share any info from sandisk. Thanks.

These cards have a limited lifetime warranty on them. Why does your 2nd one (replacement) not? Is that the limitaton, only one warranty replacement per customer?

Here in Phil when they say 1 year warranty, they will replace it for as many as you want as long as its inside the warranty period. In my case , the 2nd card is outside the warranty period of 1 year. How is your card?

It happened to my 64gb ultra sdxc sdcard some time ago and I’ve tried a lof of methods too to format it but nothing was succesful… So the only way out is sending it to a service? Where should I send it if it was bought in Poland?


hi, could you guide me how I can get my sd card replaced? i bought mine at gamextreme, i still had the receipt - i just can’t remember their return policy. were you required to surrender the non-working card? TIA.

Hi All

I’m facing the same issue as I’m not able to format my Sandisk SD 64GB Card. I tried all the ways to format it  but no way and no solution so far. I thought it’s only me but after i have done some google searches i found many people d=facing the same issue. what a lose of data and money!!!.


Exactly same with me.  I am using also Note 2 with 64G sd card and facing the same problem.  I have tried whatever program such as SD Formatter 4.0, Disk Manager, EASEUS Partition Master, DiskGenius, Hard Disk Low Level Format Tool and etc but failed to fix it.  Please give us response!!!

Ditto on the symptoms in my Samsung Galaxy Note II.  My 64GB SDXC sarted doing the same things after nine months of perfect service: videos won’t delete, pictures from my camera corrupt and it won’t format.

The OS on my phone hasn’t updated in quite some time and nothing else weird occured.  I submitted a request for a warranty replacement since I’ve only owned it for almost ten months.  I don’t really expect a resolution but wanted to post my experience here too.

I cant believe there are a lot who is experiencing the same thing. Just notice this happening to me a few days ago now its stuck to the contents it currently has. I hope there is a fix for this

I’m having the same issue with the 64GB SDXC and my Note 2. My Note 2 was recently updated to Android 4.3. Up until then things were working fine. But recently images that I have been taking have been corrupted and can’t be viewed or played (in the case of videos). 

I can not reformat the card either. I’ve tried in Windows 7 and receive a Format Complete message. And the card says 59.47GB available, but then all of my pictures come back, and I’m left with 20 GB. These files were supposed to have been deleted in the formatting process. But apparently not.

If there is write protection on the card then that makes sense.

This is frustrated. Any solutions yet?



I have ever encountered the similar memory card problem before. In order to save both of this card and inner stored data, I have also tried a lot.

Firstly back up all stored inaccessible data with the help of some card data recovery tool like 4Card Recovery

And then try to format this card with a professional card formatter, though this formatter finally cannot format my card successfully.

So, I have no choice, but to replace this card latter.

But, fortunately, I have rescued my data with that data recovery tool.

Note: Just learn a lesson to back up all important data at least on two memory cards or drives in the future.   

After I purchased this card, not quite a year ago, I read forums similar to this about the 64gb micro SD card and Note 2s. Well it fianlly happened to me. I didn’t realize I had a problem until I tried listening to music on my phone and it not recognizing any music from my card. What is really surprising is that this thread is on SanDisks site and they have not chimed in on this problem. I am on Amazon a lot and Kingston chimes in whenever they see a rating of 3 stars or lower. I guess I’ll try reaching out to SanDisk.

I’m facing the same problem. If this isn’t resolved, I’ll have to post a negative review of the card on Amazon.

FYI, my card is the:

SanDisk Ultra 64GB MicroSDXC Class 10/UHS-1


I’ve tried all the recommended format methods, can’t format/delete/write to this card from either Windows or Android. I even tried formatting via a camera, and it didn’t work.

You can resolve it by simply calling Sandisk for a warranty replacement.

Thanks, I’ve submitted a message to support via the site, but I’ll also call. Also, when I checked today, there already were plenty of negative reviews on Amazon from other customers with this problem.

Add another one to the list. Mine was in a Samsung Tablet Note 10.1

Bloody annoying after 18 months being perfect.

I will wait to see what happens to you guys

I called customer support as Tapeworm suggested, and they looked up my online support ticket submission and issued an RMA with UPS label. I just need to drop off my cut card (yes CUT - my agent said that I can cut the micro SD card in half in order to ensure that my data is inaccessible by anyone on the receiving end) at UPS and then they will send me a replacement.

FYI, you should ensure that the customer service rep records into his report that you will be cutting/drilling a hole/etc in your returning card. I wanted to make sure they are fine receiving a physically broken card as evidence of ownership. This was key, since the card retains your data, since it cannot be formatted or deleted. (I even tried a 30 second microwave while in a cup of water, but that didn’t destroy the card - so I ended up cutting lengthwise in half with pliers)

Thanks, Tapeworm for the suggestion to call support.

I have no solution to bring, but just wanted to add a “me too” to show the problem is still occuring :frowning:

My card is a microsdxc sandisk ultra 64GB that I have been using with my gopro hero3 without any issue for nearly a year (purchased April 2013). It only just started to give me problem: the gopro now gives me a “SD ERR” error, but using it on my phone or PC, I have the same symptoms you describe: I can read whatever is on it now, and it *looks* like I can delete files or format, however as soon as I plug the card out and in again, it’s back to the old state. I’ve tried formating from my phone, and from by ubuntu PC (fdisk+mkfs.exfat), nothing works :frowning:

I have sadly misplaced the purchase receipt, but I still have the packaging that states the lifetime warranty. I hope that’ll be enough to get me a (working!) replacement.
