Micro SDHC

If your computer isn't reading the card, it's probably because formatting it messed it up and/or it was defective from the factory. If no device is acknowledging that the card is plugged in, there is nothing that you can do with it. Throw it out and start over. When you put a card in your phone if you are not show a message that asks you to format the card, there is no real reason to do it. I've have many cards and I only format them when there is a problem. Formatting, just because of what it is, has the ability to reduce the life of the card.

What is this HC that you are referring to? Is it the type of card - Micro SDHC? If so, an SD card will not fit in your phone. The only card that will fit is the Micro SDHC.

If HC means something else, please let me know and I will try and help.

Thanks once again.  I haven't went out to buy my new card yet, decided to get sick instead.   Hopefully tomorrow I can though.  Thanks for all the info.  Yes, I did mean Micro SDHC.  I did not know that high capacity was in every card over four gigs though.  That is nice to know!  The guy where I bought the phone was blaming it on the card being high capacity.  Since some of you use it on your hero, I now can ease my mind and just go get me a new one!

Thanks!

Holly, did you get it fixed?  I bought a super cheap 8 online and was kinda worried, but i put it in my phone, formatted it, and then dumped all my shite on there and it was fine...

Connect your phone to your computer and in Notifications (the menu that you slide down from the top of the screen with your finger) on the phone, select USB Connect, then select Mount. Now you can see the contents of the phone drive on your computer. Insert the new micro sd card into the sd card adapter that came with it. You can now insert this adapter into your computer or if you don't have an SD card reader in your computer, you can insert the adapter into a usb card reader. Once the phone is connected with the 2gb card accessible and the new 8 gb card is connected and accessible, simply copy and paste from the 2gb to the 16gb.

After copy/paste is complete, go back into Notifications on the phone and Unmount the SD card in the phone. Then I would suggest you turn the phone off and swap the cards. As far as formatting, I think it is a matter of personal preference and not one that I use. However, I suggest that you copy/paste instead of cut/paste just in case something goes wrong. You might also be wise to put the files from the 2gb on your desktop as an additional method of backup until this process is complete.

Questions? Ask:)  Good luck.
