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!
Yes they can replace it… I just received shipment of two 64gb micro sd cards that also failed in same manner like yours… contact their support and if u still have your failed micro sd card. …u will be answered
I personally do not have a SanDisk Micro SD, but I do have a 4GB Sansa Clip+. I also have a 64GB Micro SDXC which I was able to reformat to FAT32 and use on my Clip+. I learned the hard way that Windows is unable to properly detect a 64GB SDXC card. I had to use an SDXC card reader for it to be read. Normally SD cards have an SD adaptor that you could use to insert on your laptop or any other card reader, trust me, I tried but only worked with an SDXC card reader I had to buy separately. I tried a lot of software to format the card to FAT32 but the only one that worked was RMPrepUSB. I do hope this helps a lot of you out there. Let me know how it goes.
thats fair enough. i am having the same problem as everyone.
however, what happenes to the personal date and photos store in the car that no longer allowes formatting?
are we to simply trust SanDisk with our private content? mu card is within warranty and i want a new one but do not wish to hand over my personal conten stored on the card.
so what is the way forward seeing that i can not remove such content and do not trust SanDisk ( i.e. see what happend to sony - same could happen to SanDisk)
That is really not helping - this is a forum, please post the answer here to the question so we can all see it rather than everyone pointlessly asking the same question to Sandisk support.
I also have a failed 128GB micro SDXC card (just suddenly stopped being able to write to it, has around 75GB on it right now and worked fine up to that point) which has personal data on it I want to wipe before returning it for a warranty replacement. My card seems to be stuck in the write protect mode described in this thread, is there an way to override it temporarily to wipe the card? I have the data I want from it so I don’t need the card to protect its data.
My own 64GB micro SDXC card has failed in exactly the same way as everyone elses.
As I am unable to wipe my personal data from the card due o this widespread fault I am also not prepared to send the card with the data intact to Sandisk for replacement.
I will be emailing/chatting to Sandisk about this later today and I will report what they say later. I will suggest that I would be prepared to return the card if I can cut it into two pieces to ensure the data is destroyed. I think this would be a sensible solution.
OK, I have now spoken to Customer Services and I explained the problem to them. This is the conversation:
Clauber B.: Hello, thank you for contacting SanDisk. My name is Clauber B… Please give me a moment while I look into your question.
Liva B.: Hello, thank you for contacting SanDisk. My name is Liva B… Please give me a moment while I look into your question.
Clauber B. has left the chat.
Liva B.: Please be advised that SanDisk RMA policy is to replace products under warranty, once the defective product is received in one piece. We do not review data.
Dave Sibley: Thank you. I appreciate that but I do feel uncomforatable sending you this card with personal, confidential information on it. As a possible solution, would it be ok for me to cut the card into 2 pieces which will destroy the information the card contains?
Liva B.: Alright, we will make an exception for you to return the product broken in pieces.
To provide you with a sense of security, you may break the SanDisk defective device and ship it back to us.
Also, please print out and include this update so that our Receiving Department does not reject your RMA.
Dave Sibley: Thats very kind. thank you for your understanding.
Liva B.: You are very welcome.
Is there anything else I may assist you with, Dave?
Dave Sibley: No thank you. You have been very helpful.
Liva B.:
Thank you for contacting SanDisk, and have a great day, Dave.
i think i got same issue with my Sandisk Ultra 64gb,
SDFormetter says its “Write Protected” but its not the Switch on the Adapter.
if i check the via CMD, Diskpart in Windows the Volume or Disk Details it tell me no Write protec or ReadOnly and succesful clean.
nevenmind what i do, delete or copy new data on it, after plug out and back in the Data state is resettet. Same in my Phone, can use it till i unplug the card or reboot phone, microSD card will reset to the current state.
In Linux using gparted i got an “unable to write format changes into kernal” error, that looks like the Card locked itself like said here:
