any ideas why it wont work and makes my fone freeze. looks like i will have to save the 32gb for a dual core nvidia tegra 2 phone.

does it freeze when you launch android or just freezes in winmo 6.5?
if it only freezes when you are launching android, backup the card then format it in winmo (you'll find under settings) and restore all files to it and give it a try

That link takes you to a 16gb class6 SDHC card made by Lexar.
It also happens to be the highest capacity card they sell on that site. Trust me.. I looked.

Download h2testw, run a full test of you micro sdhc card and make sure it's functioning properly.

dont you read anything. i said now i bought this one with the eprovided link from ebuyer

it freezez in winmo.

Just in case someone is still having issues, this is what I experienced.
I bought a Sandisk 32gb micro card, formatted (quick) with windows, put it in the HD2, and had nothing but problems (many hours of trying different things) trying to watch AVI's, or even install larger CAB's.
I read here about the SD assoc. having a free format program (SDFormatterv3.0.zip), I downloaded it, installed it on my WIN7 machine, did a quick format, not much change, did a full format (took over 3 hours!) card now works perfectly. Amazing.
I sure this is not the case with all Micro cards, but it sure helped me. Oh, I did the formatting while the card was in the phone, the card was set as "Disk Drive". (settings, other, USB)

I can vouch for the official format program fixing problem cards.

Well an update. The program does a very good job on formatting the micro card, but it does not detect a fake card! H2testw.exe does, excellent little program. Turns out my 32gb card was 2Gb! Windows and the SD format program both reported it Ok, but If I wrote over 2Gb, files disappeared or didn't work. (doah) just couldn't believe I got ripped. Anyway, buyer beware, and check those cards before you loose important data.

32 gig card
As far as I know the hd2 does not support any higher then a 16 gig micro sd.

It supports sdhc so up to 32GB.

Shows what you know. Almost all the HTC phones produced in the last two years have the abilty to use 32gig cards.

That's what I said... Unless you're replying to another post, in which case - quote, if it's not directly above yours.

Well I finally locked onto a 32gb card. Got it from Buy<DOT>com, quite a few for under $50 now. Ebay... <sigh> 99% of them are fake, defective or scams.
My Tmobile HD2 runs great with a class 4 32gb card.
All I can say is avoid Ebay for your cards.
For those running on Tmobile firmware (I do still) there is a new ROM release that radically improves battery life, I am getting 100% more op time. I am not a heavy user. (5 days now, vs 2 before)

Swapping out the MicroSD card of HTC Surround

Ok... I'm not so sure If i was supposed to make a new thread or reply to an old one... but If you replaced your MicroSD card, then what kind did you replace the 16gb card with? I put in an older 8GB C4 card and my phone is not working as well as before. It is not responding during sync and it opens applications a bit slower. Every time, after about 5 minutes into the sync operation, it stops responding and I have to reconnect it to my computer, and I fear that it is overcharging the battery.
So just curious, what brand, model (if you have it), size, and class, are you using currently?

SD Cards
Hi Kuree,
The first time I replaced my SD i used a Lexar 16GB Micro SDHC (it has a 4 in a cirlce on it as well). This one worked perfectly, syncing and there were no slow downs what so ever.
The card i have in my surround now is Also a 16GB MicroSDHC (with a 2 circled on it) this card also works perfectly. i'm not sure on the brand name as this one doesn't say it but I'm pretty sure it was a Lexar Mobile version.
I've only used 16GB cards so i can't exactly tell you if the 8GB card is the root of your issues.
Hopefully this helps you out!
If you have any more questions let me know and I'll see if i can answer them.
Take care,
Coockoo

problems....
I guys, sorry to resurrect an old thread. I'm having issues with upgrading to 32g... after hard resetting the phone and setting up time, the phone just gets stucked in "installing apps". It just seats there.
Any suggestions or things I should try??...
Any help will be highly appreciated...
thanks

Hi,
Is "ADATA" micro SDHC 4
They told me (were I bought this) that this card should work.
Now I can't even read or format the SD card....
Thanks!!

I didn't even know the surround had a memory card slot, where is it?

Any chance to revive the "adata" card?. I would really hate to trash 26 bucks...
To LKMR, search youtube, there is a nice tutorial on how to expand the memory of the phone.

I used a Sandisk Class 4 32GB. No problems at all... WELL worth the price and effort. They are also VERY cheap if you keep an eye on Deal a Day. I've bought 4 from there so far, the last was like $20.

Samsung 64gb xcsd class 10 card problems

Is anyone else using this card, or had these problems? Card mounted fine when I first took it out of the package. File Transfer from my backup on my Ubuntu 13.10 powered Dell d630 Lat. to the card in a USB 2.0 reader was real slow. Had problems with files disappearing, folders showing up empty, and apk files becoming corrupt and unusable. Card comes in extFat32 format.pulled the card, wiped it and formatted it to fat32 using gParted.transfer the second go round was a lot faster for the most part, but files disappearing and folders coming up empty still happening.i even re downloaded several files just incase they were corrupted during the transfer. Is it a bad card, or are there problems with how s4/MJA handles 64gb cards?

I have the same card and I have no issues. Just take card back and swap it. Less headache and down time

I recently bought a sandisk class 10 64gb XDHC card and have had 0 problems. I agree with the poster above. Be sure (Since it's off of ebay) you really are getting what you pay for. My card was $50 from amazon. Don't know if you got it super cheap or something from ebay but that could be your problem. I would exchange it and if that still doesn't work then you are most likely getting mislabeled fake cards. Memory I always try to get from the manufacturer or reputable company because there are TONS of fakes out there.
Again I'm on 4.3 MJA stock with root and philz recovery and have no problems with mine albeit a different brand.
Best of luck though!

For what it's worth I had the sandisk 64gb ultra (from amazon) and had issues constantly with it becoming unmounted, despite anything I tried.. Some have no issues with the sandisk. Prior to that I had a sandisk 32gb ultra and never had an issue at all, which is what I expected from the 64gb sandisk.
It didn't take me long to switch to the same samsung 64gb (from amazon) you've got, no issues at all, and it's been several months now....
I think the others said it right, get that thing replaced for another...

Micro Sd card issue.

Got my v20 yesterday but its mot reading my 128 gb micro sd card . guess I'm going to have to format but transfer all my files to computer first . can't loose I have a lot . The card is SDXC .
$oul€$$ D€m0n!

Thanks for sharing.

You forgot to disclose the manufacturer and model of the card. Havent had a problem with any micro's in my v20.

It's a Samsung SDXC
$oul€$$ D€m0n!

Im having issues with sd card with camera saving to sd card. Also when i crop a photo it won't save. Using my 256 card from my Note 7 that cane with phone. Never had a issue on the Note, with the V20 km.about to just use it for the DAC only n go back to Note 5. Permissions in Google have been charged to give permission but still cant saved edited photos

I recently had a Samsung sdxc evo class 10 fail (suddenly couldn't write anything despite having 80gb of free space left).
Did manage to copy the data off of the card but I ended up having to get a new card, this time I went with SanDisk class 10. So far so good.
Wonder if there is a defective batch going around (I purchased mine about a year ago)

I have the same card from Samsung,( it was free with the Note 7). Unfortunately, I'm still having problems playing videos. I've tried VLC and MX, but both only play some of the files from SD. Any suggestions would be greatly appreciated.

Definitely have to format. If you'll notice the card is assigned I don't know what to call it and filesystem may have been handled differently. I had to do same. Took time but works proper.

Same thing happened to me, 128gb card bought about a year ago. I had to buy a new one.
This new one has been "corrupted" twice now to where I had to format it.

Thanks for sharing. But none of those is related to my issue. My card isnt corrupted. My v20 just wint read it but when I put it back in the v10 all is fine also my computer reads it. But the v20 dosent even see external storage that is my issue

I believe you are right I just popped in a 8gb san disk I had brand new never used and phone doesn't ever register it. But as far as I know regardless of Sd card inserted ir not the phone should show external memory in the menu

Probably needs format on phone.

That is correct. The phone should detect it regardless of the need to format or not.

I solved this by moving the SIM from the main slot to the side slot (dual SIM model). Weird thing was that anything < 64 gig would read fine, larger SD cards wouldn't. Only thing i can think of is a design flaw whereby the SD card is getting pushed up and not making contact properly due to the SIM underneath it. Try taking the SIM out and seeing if it will read/format/re-read it then?

I have an ATT LG V20 that experienced the same symptom so I tried similar procedure by remove SIM card and insert the micro SD then boot up to see if it would first see the SD card and it did, after that I shutdown and reinsert the SIM card and everything is still working.

S7 & S7E killing my SD Cards....GRR! Any ideas?

I don't know if it's something I'm doing, but this has happened twice now (both with an S7 and now my new S7E).
I bought my S7 with a SanDisk Extreme 64GB Micro SD. After a few months, I kept finding that on taking a photo, it was diverting to internal storage over the SD card. Rebooting sorted it for a while, but it reached a point where it locked itself and could only be read, but not written to. I sent it back to Sandisk and they issued a replacement.
Since then I've now got an S7E (I was part of the N7 scandal). I'm using the replacement Sandisk card I received and today EXACTLY the same thing has happened. The card has become completely locked. I can see the data that was on it from the S7E before it locked up, but I can't write to it. In fact, I can't even format it. If I put it in my PC I can read everything on it but otherwise it's bu**ered.
Where am I going wrong with my S7's and SD cards. Any ideas?
Cheers.

I had the same thing happen. My Sandisk 128gb got corrupted, sent it back for replacement to Sandisk. Then the replacement got effed. Then I bought a Samsung Evo 128gb and it got locked somehow. There are files on it that I can see with a PC, but when in a phone shows as corrupted. Cannot format, cannot do anything with it. I got another 128gb Samsung from Amazon and so far is working. I am worried it will do it again.

Can i ask which version of s7/edge you guys have ? I got the exynos model (n7 scandal as well) I popped in a 128 gb evo card, I'm worried it might do that to me :/

And me. What I've decided to do is just put music on it (i.e. read only)! That's what it's mostly for for me anyway.

Mine is also Exynos!

Well for me, it started when I had the AT&T 935A S7E with the SanDisk, but I now have the Exynos S7E and it is the one that the Samsung micro SD went bad on. So both models caused issues. I do flash custom roms and things and know the risks, but have never had this happen on any of my S2, S3, S4, S5, or S6 phones.

I got the same issue but I think its the card with the HC card I didnt have problems but with the XC card it got corrupted...

Try a different SDCard manufacturer to SanDisk?
Possible the replacement was from a faulty batch of cards the original was also from
Think I'm using Kingston

Did you read my post? It happened to me with a Samsung too.

Same issue here with Silicon power 64gb.

Might be the whole XC thing.... I have an old 32GB Samsung EVO knocking around. I'm gonna see if I can kill it haha! Otherwise I'm going to have to send the dead one back AGAIN.

I had te same issue on 3 SanDisk cards all SDXC, I concluded to stick with SDXC, got for the extreme versions.
I tried everything to recover or format.

For those with locked files on the SD, what did you when sending it back?

Probably connext ur micro sd card to the pc and done diagnostics and correct disk sectors.

Doesn't work. Already tried that.

There is a command you can use on dos that fixes read write or bad partition errors on sd cards . Check this link

Yes that's what's I've run already on my cards. I have tried everything I can find. I do work in the IT field though I'm not a programmer. The closest I've come to getting somewhere is using an application called testdisk. http://www.cgsecurity.org/wiki/TestDisk It will help you recover any files lost but that isn't my problem. The one thing I will say is I'm pretty sure all mine have been formatted as eXfat vs fat. I had one go bad when I was messing around with adoptable storage.

I also used to work in the IT field! I spent about 8 hours last time trying to repair the card the first time around - in the end I just sent it back to Sandisk. You need to request an RAM on their web site.
And yea, no CHKDSK /f, or DISKPART CLEAN will touch it. It's so odd how the phone can render a card useless - yet still be completely readable.

I have an sandisk extreme pro 64Gb sdxc since april. Only use it for photos and downloads, sometimes to listen to music. It still works flaweless *knocks on wood*
Have you guys formated the card in the phone? This cause some really bad performance for me, i formatted it with my pc and SDCardformatter and the performance is better now. But sadly not as good as out of the box. Maybe samsung screw something up while formatting with the phone?

When this happens, the card is locked. If I format the card in the phone it claims to have worked - yet nothing has actually been formatted. If I use SDCardformmatter (or Windows, or any of the 3rd party tools) they all fail. "This disk cannot be formatted"!

Yes I have put them in the phone, and my card says corrupted when in the phone, yet works fine (other than being write protected) in my PC. I did request an RMA on my first 128gb SanDisk, then it happened to the replacement, then it happened to the Samsung 128gb, and I am on my 4th 128GB which is a Samsung EVO Select. I thought it might have had something to do with not doing the full wipe of data in TWRP recovery before switching roms. It does say doing full wipe removes encryption as well as wiping data.
