Hi,

    I bought a Sandisk 32gb Micro SDHC card with class 4…It is not detected by my android phone.So I tried with windows phone.Result is same.Then I try to connect it through a USB card adopter to my PC. It asks for Formatting the removable disk.When I try to format it in basic FAT,NTFS or exFAT it shows only 30.6 mb capacity and a prompt message “Windows was unable to complete format”. 

Please Help!

Thanks!

You might try formatting using the SD Association’s Formatter tool–it can handle many issues.

One thing I hope this is not:  there have been many reports of fake 32GB cards.  Hopefully, that is not your situation.

Something is amiss with that card.  Try formatting with the SD Formatter listed above, and check that it is a genuine 32GB microSDHC card using H2testw linked here.

The applicationH2testw will check the card’s actual details, verifying it isn’t a counterfeit card.  Sadly, the higher capacity (HC) 16 and 32GB cards are prime targets for counterfeiters on the internet.  What a scammer does is take a smaller-capacity card and rewrite the identity on the card, making you “think” it has more capacity than it actually does.

Download and install the utility, and check the card out.

Between using the SD Formatter utility, and the validity test, you should be up and running.  If the card is genuine, SanDisk stands behind them!  You can contact Support at 1-866-SanDisk for assistance.

i think there is something wrong with the 32 gigs  i   purchased  32 gigs from radiosahck  i . oppened the pakake and  kept only the card with the little plastic box so when i tried it on my samsung  note 2 it said that it was bank or unknown files so i tried to return it and radio sahck couldnt take it cause  i didnt have the  whole  pakage that it it came with 

i had to repurchased another one same kind  and exchanged it  so  i put the damaged one inside the pakage and took it back to the store its been only a  month am using the new one and   today its useless  cause its giving me the same message , am so pissed  cause i lost all my christmas pictures

You might try reformatting the card using the SD Association’s Formatter tool (available online)–that sometimes has been known to help.

I have the same problem with a san disk 32 gb… It was working great but then all of a sudden my Samsung Galaxy Note 2 told me there was a problem and it needed to be formatted. 

I pressed cancel because I was hoping to save the contents of the disk.

Now my Note 2 does not even recognize the card at all.

I saw this post:  http://www.droidforums.net/forum/samsung-galaxy-note-2/237385-erased-sd-card.html

Which says there is a problem with San Disk 32Gb disks not working after use.

… and just to update, the card does not work in a usb reader either… My Mac does not detect it at all.

This is a fail SanDisk!!  I bought this on Amazon so getting a replacement card is probably not worth the hassle.  :(

Ther has been a lot of buzz about these cards in the Samsung phones. No one that I’ve seen has determined definitively whether it’s the card failing or the phones killing the card. I’m sure SanDisk is feverishly researching this; I can only hope Samsung is doing the same so the issue can be resolved somehow.

Not sure what you mean by this–getting defective items replaced by Amazon.com is the easiest thing in the Internet commerce world, with Amazon sending you a pre-paid mailing label, if you want, for dropping off the package for UPS delivery, and providing free postage in sending you a new, non-defective replacement.  Now, matters are a bit different if dealing with an Amazon Marketplace seller–but even there, Amazon will back you up with its Marketplace Guarantee . . . .

The majority (if not all) of these issues seem to be ocurring with the Samsung (particularly the Galaxy and Note) phones. It’s imaginable the problem lies with the phones themselves, rather than with the Sandisk cards.

Has anybody explored that possibillity by questioning Samsung’s Customer Service/Tech support?

Hey im having the same problem as everyone else. Have a 32GB SDHC card and its dead like the othere posts. Cant be read or formated in Visa or Win7. At the time i started getting a message saying the card had moved in the phone. It did move as the phone was not dropped or no shap moves at them times. The phone is a Samsung S3 4G.

Hi I’m also having the same issue on my Note 2. I bought the 32GB from a reputable local store just a few months ago. After I’ve copy my file to the memory card, it work perfectly for almost a month. Then, I started receiveing different kinds of messages like : a blank SD card was inserted. The card contains some invalid format. jIt is asking me to format the card. When I tried to format the card using the phone, pc, and mac, it is not allowing me to do so. Now, the card reader can’t even recognized the card.

Hi guys  I have the same problems, had an s3 with a 16gb microsd card then moved this card to my new note2 a week later got a message on the phone telling me unable to read sd card . Put the card in my pc and only show 30mb available, Did some research and found out that my sd card file system has some how been changed by the phone from fat32 to raw. My pc and phone cannot read raw sd cards so now trying to find a way to format the card back to fat32. Tried on windows but won’t work, tried in dos but does support raw . So any help guys?

I’m having the same issue.  I have a Sprint Galaxy S3.  On 3/4 my phone went through some updates and I am on Android version 4.1.2.  That evening, my phone shut down because the battery went too low (first time…phone doesn’t get a lot of use).  After charging on 3/5, about mid-day, I got a notification that the card was unmounted.  I’ve tried remounting the card on the phone & also tried reading the card on a pc and mac…nothing.  The card is no longer recognized.

I’m not sure if the update or the battery loss contributed, but my card is now MIA.  I bought it on Amazon and will see if I can get a refund/replacement.

I am having the same issue. Does anyone know what is going on with these micro SD cards. I am hoping to get my money back or a new one. I was able to open the card from my computer and found a folder called “LOST.dir” .  I copied files and recovered most of my pics. I am changing the file extension name for every picture  that was saved in that card.

Dear, i had the same problem with 64 GB and solved it with Installing this update to add support for the exFAT file system format and it worked fine with me without even formatting the card

please try it
