Turnoff antivirus bet that's the problem and also what OS you using,64bit,your hard drive is SSD?
Many thing can be happening, Hdd smart errors giver it a try with speedfan it'll tell you the hdd smart state so you can discard problems and achive best performance.

check if usb debugging is on and disable it

Will a microSD card with an SD card adapter work in the SD card port on the Dock?

I realize that this SHOULD work, but I know there are issues with some memory cards, so I thought I would check. Has anybody used a 32GB microSD card (in an SD card adapter) in the dock?

I've just checked that for you with the MicroSD card that I'm normally using in the tablet itself - works flawlessly in the SD slot.

Yes. Even the incompatible microSD cards work with adapter in dock.

I can confirm this is the case with mine as well.

My guess is that the SD card slot is actually a USB card reader which its own controller. Just a guess, but would explain why it can read these cards when the integrated microSD cant.

And a good one, as the SD card reader in the dock is governed by a USB host.
It is still not recommended to go with NTFS in any of these, however.

64GB Micro SD Card format

Okay random question but I'm getting a 64GB micro SD card and all I need to do is format it and I'll be good right? Like i don't have to worry about any issues? I want a 64GB but I heard about issues people had so it may sway me to a 32GB. Thanks for any response

You don't have to flash it to FAT32 in order to use it, but if you flash a custom kernel or JB, the phone may have trouble recognizing the card. Formatting it as Fat32 removes the issue.

Plus CWM Recovery won't recognize it unless it's Fat32 also. Not sure about TWRP though...

It's always best to reformat sd in fat32. It reduces unneeded headaches.:thumbup:

I left all three of my 64gig cards formatted the way they come.
They work just fine that way and that allows me to store files over 4 gigs which is the limit for FAT32.

That's fine assuming you want to stay on a stock rom. If you plan on flashing AOSP/CM, then you're going to end up with a corrupted card if you leave a 64GB card as exFAT

You would have to re format it as exfat. But then you run into compatibility problems mentioned above.

Ah damn that sucks. I'm actually in AOKP right now. So I can basically throw the idea of having HD movies on my 64GB right out the window right? I assume an HD movie is more than the 4GB file limit

ALL of my BlueRay rips are over 4 gigs.
I could rip them to a smaller size if my only use for them was to play in the phone, but I use them for other uses & I can't see the point in having 64 gigs of space but blocking the ability to store large files.

Damn its a tough choice. Get a 64GB card but format it to work with both AOSP and TW but losing the ability to have HD movies over 4GB. And I know I'll burn thru a 32GB card real quick

How do the 64 GB cards usually come formatted already?

[Q] SD card is damaged.

I am getting a message that says "SD card is damaged. Try reformatting it." Is this referring to my external SD card?

Yes just format it but you will lose everything on it.Everything
Sent from my SGH-I997 using xda premium

The way to find out is to either remove the external card or download an app to check the sd cards.
If you are going to format, try to copy the cards over to your computer first.

When I mounted to my Mac, only 1 card mounted ( the internal) instead of 2. I copied everything off and formatted it just for my own peace of mind. I then copied only what I absolutely needed back. After a reboot, i had the same error. I then shut down and removed the external card, and no more error messages. No great loss, nothing on there that I don't have a backup of already. I guess I need a new external SD. This one was only a class 4 anyway. Do I need to move up in class?

Upgrading classes isn't required. You can go out and buy another Class 4 or even a Class 2 if you so choose. The only difference is the write speed (4MB/s vs 2MB/s respectively). If you use an APPs2SD type app than a Class 6 card will be a good recommendation for you to get as it offers 6MB/s write speed which in turn cuts down on loading and saving times of any apps you use off the card.
But in terms of upgrading classes because it's required, it's not. Buy whatever class card you need or want to buy.

Gs3 wont recognize 32gb sdcard?

Hey guys, I just recently saw when I turned my phone on, it says sd unexpectedly removed, when in fact it is in there. If I take it out and re insert it, it doesn't say anything? I would try to use this on my laptop but I know the reader on my laptop is busted (plus I'm at work). Any help would be greatly appreciated!

Not sure, I had a 32gb card myself and it started acting weird on me. Doing th e are thing, acting like it wasn't there, needed formating or some such. I switched to my old 16gb card from my droid X and it worked perfectly. I think not was just a bad card. It's possible as the prices came down and these cards got cheaper the quality control has dropped. . I might add that that was my second 32gb card The first one wouldn't even work in my laptop when i tried to format it and got so hot that it burned my fingers when took it out!
Short Story is you may have a duff card. Try an old sd card just to make sure it's not your phone.

I know it's not my phone, tried my friends card and it worked. If I insert my card in his phone it says blank sd card and when I try to format it, it says in know media state....

Sounds like a duff card. What brand of card is it?
I'd say as a last ditch attempt when you can try using a laptop and make sure it's not formated to exFAT. When mine went bad my laptop wouldn't even let me format it

I had a generic 32GB card workinf for me perfectly from day one, but recently I bought a SanDisk 64GB and I can't get my phone to recognize it (my computer does), I'm thinking it has to be in the right format, which formats will the phone recognize and which won't it?

Try it in cwm. There is a page that does give info on partition and speed somewhere on the net.
Afterward, fix permissions.

Fat32 if you intend to be a rooted user

Fat32 is the stock format OOB and will work well with all devices.
Ext4 is androids partition for apps.

How do you format on the phone?

Settings >> Storage >> Format

tried that to, still won't work.
when i try mount it says damaged sd card reformat.
i've tried formatting it on the computer in exFAT and NTFS, the only 2 options windows offers
