Can anyone tell me how to reformat a micro-SD card?

[Newchapter]

Can anyone tell me how to reformat a micro-SD card? I need a larger micro-sd (4GB to 32GB) and now my phone can't access my info. (I did unmount the old card, saved it, and copied to 32 GB and remounted.) Could using an encrypted format have anything to do with it? I really need help fast because all my life's stuff is on my phone!!

Either the phone itself can reformat the SD card or you can format it with your computer and a card reader. You should verify the maximum size readable by your phone and the file formats it supports for the SD card before formatting.

The easiest way is to use an SD card reader. Many computers lap tops and desktops have a reader built in. Or you may have to purchase one.

Take the old one out with all your life's stuff and place into your computer. It will register as a new drive letter.

Click the drive letter and go and select all your folders, files etc. And do a copy then make a new folder on your desktop (make it first is even better) then right click on the desktop folder and select paste.

Then go to the new folder and verify the contents are all there.

If they are you are now fine.

If you are placing the old contents on a new larger SD card I would place the blank SD card into your device and do a format of it.

Once formatted remove it and put that into your computer. Then go to the data in the folder and select all.

Then right click on the new drive letter where the formatted SD card is at, select paste.

I would keep all the documents in the computers desktop folder for future use.

The older 8GB can be formatted or just leave the documents on it as a spare.

Do not select CUT under any circumstances. Only copy and paste.

Or all will be lost.

It really is easy after you do it a few times.

Good Luck
