32gb Micro SDHC card is not detected by phone and unable to format in PC

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 application H2testw 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.  Smiley Sad

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 . . . .
