Re: FORMAT 64GB MICRO SDXC PROBLEM

I have 8 of these cards (64Gb and 32Gb) which cost us over £300, and after a few months of service, none of them work. We are asked to reformat, but only 30.6Mb is shown as memory, and then neither Windows nor Mac can format any of them. They are within warranty, and I hope that SanDisk will honour the warranty. So far, they have sent me a reply asking for a lot of information about each card, much of which is hardly visible. Let's see what happens, but they do seem to have a quality problem with their cards.

Re: FORMAT 64GB MICRO SDXC PROBLEM

Just to be clear, this thread is concerned with the 64GB SDXC cards. Only the 64GB size is the newer SDXC format. the 32GB ones are still SDHC.

Re: FORMAT 64GB MICRO SDXC PROBLEM

I had similar problems with my Sandisk 64GB micro sdxc when I attempted to mount the card in my Samsung I9300 International version. After formatting the card with my Windows 7 operating system my phone displayed the following message: 

 

"SD card is damaged. Try reformatting it."

 

The solution to my problem was to format my SD card in FAT32 instead of exFAT. 

 

I did this using the following method devised by http://forum.xda-developers.com user lynkdead

 

CONSEQUENCES OF METHOD: 1.) this process will erase all data on the card.

                                                             2.) you will no longer be able to transfer files larger than 4gb to the card 

 


1. Place the card in your PC's card reader and determine the drive designation (i.e., G:\, H:\, etc.)

2. Download the fat32format utility in GUI version from here: http://www.ridgecrop.demon.co.uk/guiformat.exe. Click on the picture to retrieve the file.

3. Launch the guiformat.exe.

4. Choose the drive that corresponds to your SD card.

5. Choose the size of the SD Card you are formatting.

5. Check the Quick Format box.

6. Press Start.

Enjoy your usable SD card

The quick format did not work, just FYI ( : http://www.ridgecrop.demon.co.uk/guiformat.exe )

 

64GB Sandisk SDXC

 

Mine was running perfectly for about 3 months, no issues then all of a sudden last week it stopped saving files (any files) in my Samsung Note 3...I've tried formatting in the phone, now with SanDisk Adapter on my PC...this sucks!  Luckily I was able to copy all my files over to my PC prior....so once (hopefully) I do get the SD fixed I can reload the files

Re: FORMAT 64GB MICRO SDXC PROBLEM

I am also a victim..... I never believed SanDisk can fail so when my first 64gb micro sd card failed on my galaxy note 2 last year I blamed it on samsung but a 2nd one just failed 2 days ago.......

 

Apparently,  when they fail u neither can copy to it or delete files already in it nor format it.... I hv tried formatting it with all possible procedures n it cannot be formatted. ...This is a huge let down on SanDisk. ..... I hv three 16gb SanDisk I bought like 3 to 4 years back n also a 32gb version n they have never failed me but in less than a year, two 64gb ultra SanDisk hv failed me......I am so much heartbroken and like u rightly said please no one should buy an ultra 64gb SanDisk cos it fails more when u get to the 40gb limit.....I am presently using a third 64gb ultra SanDisk micro sd card on my galaxy note 10.1 n hv already accepted my faith that it may fail someday. .... its time to move on to a new brand...... am done with SanDisk for now......This is very very bad from u SanDisk. ....

 

THE SANDISK MOBILE ULTRA 64GB MICRO SD CARD HAS FAILED ME TWICE & I CURRENTLY BLINDLY PURCHASED A THIRD ONE BEFORE THE SECOND ONE FAILED. .... I ALREADY KNOW MY FAITH WITHOUT IT....PLEASE & PLEASE DONT BUY IT

Same issue - I purchased the 64GB Micro-sd card in Feb-2014, then found that I could not save any more files in July-2014.

I have tried everythng, including low level format, the card is still write protected. It becomes useless.

I will surely not buy SanDisk memory card again.

Re: FORMAT 64GB MICRO SDXC PROBLEM

I would like to add my voice to the list of defective Sandisk 64gb micro sdxc card. Hardly use it and now I can't reformat or delete the contents. I have tried every tools and tricks on both Windows and Linux and Android OS. The card is defective and it is a worry!

 

 

Can Sandisk replace my faulty card?
