MicroSD HC Card corrupted in Polaris

Hello!
(Please excuse me my bad english).
I have a Polaris (english version) and recently my Sandisk MicroSD HC card (6GB) become corrupted. Specially I lost all the subfolders inside /Program Files main folder (instead the subfolders I had only a couple of large files --more than 1GB-- and various other files with strange characters as name).
Anyone had this problem...? It seems that may be a problem like the Artemis had... I'm thinking to patch my Polaris with the Artemis patch but I don't know if it will work...

i have a Sandisk MicroSD HC card 8GB and no problem encountered actually.
Ziggy

I have a Sandisk MicroSD *Gb too and no problems.

I never Format a storagecard but one question: Do you Format it on pc with FAT32 and 32kb Clustersize? Try it.. maybe it helps..

Logo microSD HC Cruise
Hi guys, I would like to know the slot microSD if is compatible microSD HC and declared by HTC, so it should be a logo "microSD HC" at least on manual user or on the packaging of pda.
Excuse my bad English

It is compatible with MicroSD HC, although, the slot doesn't have a specific logo.
I use it with an 8Gb MicroSD HC card and it works fine.

8Gb MicroSD HC Format?
Those that are using the Sandisk 8Gb MicroSD HC, did you format it first? If so, how?

Format? I never have formatted a card. Just plugged it in all the time. So I did with my 8GB Card and the Polaris.

I didn't need to format the Sandisk.
However, if there is a need to format you need to format using FAT32 and not FAT16 or NTFS.

the Polaris is definately sdhc compatible...
while i was waiting for mine to get to me, i called HTC and asked this question.
i was bored and started accessory shopping before my unit got to me.
anyway, 8gb SanDisk works perfectly for me out of the box, no issues at all.

Thanks for the replies. The post above just got me thinking.

Formatting Micro SDHC
You should NEVER format these cards with standard utilities my experience is that it corrupts them and they are only recognised as 2GB cards there after...Google for SDFormatter v2 this does it correctly...

I formatted on PC (Vist 32 bit with default settings) my SanDisk micro SDHC 8GB card and works for me without any problems.

Hi,
encountered a similar problem when I soft resetted the device when an application was locked up while accessing the SD card. Fortunately I did not lose any data but had several additional folders and files with cryptic names. My solution was to backup all usable data, format the SD card as FAT32 on a desktop computer and restore the backup. Worked fine.

You can use standard utilities, but you need to know which format.
Example: for SD HC you NEED to format with FAT32.

as the guy above said.... you must know what you are working with and how to use it..
if you are using the sdhc then format it as FAT32 and it will be fine...
i also corrupted my memory card (SanDisk 8gb) by leaving it in the card and taking out the batter and sim and then replacing the battery,,,
all i did was use my usb adapter for the 8gb sdhc and format it on my pc for FAT 32 and it worked a charm...

Corrupt memory Card
Think I spoke to soon in an earlier post today my entire card vanished knew there was 3GB in use and 5GB free but nothing to show for it, all very reminiscent of the 2GB bug in the early days of the Orbit 1...

yep, I can confirm that. I've reached the >3Gb usage of my 8GB SanDIsk MicroSD card. And lost two times everything beyond 2GB of data (mostly the new ones). Looks like a bug.....had a backup. I think I will remove some data and see whats happen....
Dejan

This is such a worrying thread. Deja Vu re:the Artemis.
I'm up to 4 gig of my 8 gig card with no problems so far. Is anyone using the SD sentry program from the Artemis threads to monitor for problems?

How can I prove this? Was the data corrupted or deleted? I mean, were the files still there but broken or did they vanish?
I use 6GB so far, but can't find any mistakes.

How to move programs to SD card not internal Memory?

Dumped my buggy not impressive Galaxy s 4g today> (love Costcos 3 months policy) and picked up G2x. So far extremally impressed!
One question is the Costco phone guy handed my the 16gig micro SD card from the Galaxy as he said he had extras from dead phones. I said THANK YOU! and installed. However when using AppstoSd program it only see's internal mem, and Internal SD 5gs. It does not see or give option to move to my 16g Sd card?
My HD2 and Samsung worked great with AppstoSD. Am I missing something? I mean I guess the 1.2gig and 5gigs of internal is enough. But I like to also use the SD card for programs to not overload internal memory.
I have not rooted yet, will do that so I can get my Titanium backup working to see it I can do it with that.
Thanks!

Been all over that thread. This issue and the "phantom AT&T bands are two big issues on this device. However, there may be some hope at the CM end - not this item in the latest CM7 changelog"

First thank you for responding. I am not a newbie but have been rooting and testing my Hd2's for past year. My first non HTC phone in awhile was the vibrant s4g, it had its own problems with very low internal memory.
So I was excited this phone had 8 gigs plus now my 16 gig card. I have not been on these forums so I did not know it was a known issue Sorry.
So to clarify, there is no workaroud? But can I not just use root explorer and move files to the SD card? I understand apps to sd wont do it automaticly. But I plan to put my music and movies at least on SD... What would even be the use of the manufacturer putting SD slot on phone if you could not use it?

Ira that is what I do. SD card = sdcard/external_SD
Or something to that effect. I plan to keep my apps2sd on internal and SD for straight storage and backups.
From the sound of it, the clockwork mod can access the microsd so at least backups will be off the device.

What I have been doing is the basic copy and paste. I copy the app or video ect. from the sd card and paste it on the ext/sd card. If there is a faster oor easier way please let me know. I am rooted and this is the first phone I ever had with this kind of a set up with the sd card. I prefer the other way much better ala Nexus One.

That is correct. In a file manager etc. you can locate your SD Card by going to the ExternalSD folder (path: SD Card/ExternalSD). The "SD Card" is actually the internal memory, and the "External SD" is the actual SD Card. When you plug your phone into a PC two different drives come up, one for the internal and one for the SD Card. From what I know you can't put apps on your actual SD Card. However music, pics, etc. all work just fine. I have all my music on my SD Card and everything else on the internal.
P.S. When opening the internal memory in a PC it will still have an ExternalSD folder, but it will be empty. I would advise not deleting it.

There's something like 1.5GB just for apps. What the heck are you doing to "overload" it??

GPS maps will easily overload the internal SD card. If they let the map location be set, that would fix it, but most do not (yet).

General questions about MicroSD, error check and so on

Hey dear XDA peeps!
Ive got a couple of questions about microsd here
Ive got one 8GB Transcend card which I bought in the beginning and it seems to be working good. I then bought another 32GB Kingston card. It has worked pretty good but now it seems it is kinda fubared.. Ive unmounted it from the phone and connected it straight to the computer and Im having some problems copying stuff from the card. Which it was from the phone too..
How do I check the sd card for errors and fixes them? I dont have to keep the data on it.
What makes the sd card break? I understand how regular old harddisks die but what about sd cards? =)
And what brand for SD card shall I buy for the phone that have the best reliability?

Im trying to format the sd card but it just hangs and refuses to format it so I guess the card really is fubared :/
So what card brand do you recommend for best quality?

I've tried them all. SanDisk has the best microSD cards for the money. They are also faster than spec'ed. If you can't get SanDisk, get Kingston.
Transcend is the slower than SanDisk or Kingston. I've heard good things about Patriot but never tried them. Stay away from off-brands or you risk serous problems.
For any mobile phone get a Class 4 SanDisk. Format it using SDFormatter.

Right click the SD in windows explorer, hit properties, tools, check disk. what makes SD card go out is every flash storage has a set amount of writes, after those they start to go out. Whatever you do though, do NOT defrag a flash based storage, you'll kill it. I use a Kingston 4GB in mine and I've had my SD for years (before this phone it was used to boot operating system installs on my laptop and used for my DS flashcart

Do NOT defrag Flash-based storage, you will kill it. Flash memory doesn't need defragging because it does not have mechanical heads like a magnetic hard drive.

SanDisk Ultra 64 GB microSDXC Class 10 UHS-1 Memory Card Issue

I bought this MicroSDXC card http://www.amazon.com/gp/product/B007WTAJTO/ref=oh_details_o01_s00_i00 from Amazon and every so often my microSD card will vanish. It will not show anything on the card when using Root Explorer and my music will not play and data on the card will not work. A few reboots fixes the issue but it's troublesome to reboot all the time. Sometimes it even says the card is damaged and needs to be formatted to work so I just reboot again and then it works. Anyone else having issues with this card? What can I do to remedy this problem besides rebooting all the time?

I have also experienced similar issues with the same card I got off Amazon a few weeks ago. I am tempted to reformat it from exFAT to FAT32 only issuue I would have is any video files larger than 4GB won't translate since FAT has a filesize limit If you don't have this issue I would try reformatting to FAT32 (backup your card data first) I suspect you will have no problems

It does the same thing as FAT32 so I just switched it back to exFAT.

I've also noticed my clockwork mod recovery can't detect external sdcard.

CWM cannot read sdcards formated in exFAT, only FAT32.
If you need to format a 64 GB card in FAT32, a lot of people suggest using:
https://www.sdcard.org/downloads/formatter_3/

Maybe Samsung lied to us and the Phone can't handle 64Gb cards. Still having this issue and nothing fixes it.

I bought a 64 gb card a few weeks back when they were on sale and right out of the box I used GUIformat on my PC to format to fat32 and have never had a problem.

Maybe I'll give fat32 another chance.

Failed again today. This POS phone claims to support 64GB cards and it barely does. I'm getting pretty pissed off now.

It may also be that the microSD isn't that good either, and needs to be replaced. Other devices have had trouble with the 64 GB sandisk cards as well (i.e. Nook HD+ w/CM 10). But then again, the phone might just be temperamental as well.

I bought a card like this and I still can't get it to work, my computer recognizes it no problems but the phone won't, I've tried a few different formats. any suggestions?

[Q] SanDisk 64GB microSDXC

I thought the Galaxy S3 supported the 64GB sdxc card. I have been having the usual issues with it (losing communication with it in the phone but it is operational in a PC) so I wrote Samsung support and got this reply;
Thank you for your inquiry. We understand that you are having issues using the 64GB SDXC card on the Samsung Galaxy S III phone You have tried inserting the SD card on the computer without any issues, Also you mentioned that you h ave already tried formatting the Card using the phone. We do apologize for the inconvenience that these issues might have caused you.
Pleae be advise that your device lets you use a microSD™ (SD) or microSDHC card to expand available memory space. The 64GB SDXC is not comptible to be use with the Galaxy S III.
I thought they stated at one time it did support the 64GB memory.

I believe the 64GB capacity is supported but it may be that the SDXC type card is not accepted. Have you tried a standard or SDHC card instead?

I did a quick Google on it and found some SDHC cards. I did see a ton of SDXC cards but I think there are others available as well. I would post a link but XDA won't allow me to since I'm relatively new.

SDHC only supports up to 32GB I am going to answer Samaung support and ask them how they support 64GB when SDHC only supports 32GB.
The Secure Digital eXtended Capacity (SDXC) format supports cards up to 2 TB (2048 GB), compared to a limit of 32 GB for SDHC cards in the SD 2.0 specification

I assure you my 64 gig sandisk sdxc card works just fine in the S3.
I kinda missed all the issues with read problems, because when I got it was before I had an S3.
When I got it, I opened the package, put the card right into my T-Mobile MyTouch 4G Slide phone, formatted the card in settings, and have been able to use it in that and the S3 fine since.
Maybe try formatting the card in another/older phone and see what happens? I was running gingerbread on it at the time.

i really depends on which file system is compatible with yer kernel. SDXC by default uses exFAT which won't read with a stock kernel. reformatting the card in your phone will format using the FAT32 File system. FAT32 is a lot more compatible but it has it's limitations like cant copy files bigger than 4 gigs.

FAT32 works and it doesn't. When I play videos it will randomly cause the phone to hang, then reboot. Not at any consistant time into the video either. But the data stays intact.

I actually came to this forum to ask about close to the same question. I'm using the first card that pops up when searching "64 gb micro sd" on amazon, and frequently (while watching videos) the phone will crash, followed by 2 vibrations, and then it boots up again.
Do you also have problems with music saved on the card? On occasion, my phone will skip tracks and will only play a few of the songs. This only happens over bluetooth (so far), and manually clicking one of the songs on my phone causes the rest to work again.
I've also been having issues with the card in general. Sometimes mine will say it's corrupt at the top, but a simple reboot or dismount fixes it.
Please let me know if you find out anything.

The only official thing that I have from Samsung is that they support 64GB micro SD cards but they do not support the microSDXC, only the SDHC. 64GB is only available in SDXC. So I think the safest way is to go 32GB SDHC. Although from reading some prople have the 64GB SDXC working but many have problems with them, including myself. Another confusion point, San Disk says it will work. I have some older flavor of 16GB card in mine now and it has been very stable.
Whiskey Tanko Foxtrot

Thinking;
Is it possible to format the 64GB SDXC with multiple partitions? Create (2) 32GB partitions formatted FAT32 each.

I used a 64 gb micro sd sdxc out of the box on CleanRom. I formatted it on accident when trying to wipe everything preparing for a different rom. Now the sd card only reads 27.4 gb. I have seen countless threads on here and google but i am not seeing a solution. Any ideas?

does the de-odexed and odexed type of rom have anything to do with if the phone recognizes exfat or fat32 sd cards?

Uhh, not necessarily. It's primarily a kernel related issue. If you're using a TW rom that comes with the official OTA kernel then you'll have "no" problems with exFat. Synergy is one TW rom that I'm aware of which comes with exFat support courtesy of a custom kernel by a dev named Ziggy. Most custom kernels don't have exFat support. You'll have better results if your TW rom includes the stock OTA kernel, the same can't be said if it comes with a custom kernel. But exFat support is not based on whether the rom is deodexed or odexed.

That makes things a lot clearer. Thanks for the response.

I use a sandisk 64 sdxc every day with no issues. I used a windows program called EaseUS partition master to format it and its all good. Pictures, music, movies, flawless. On touchwiz and aokp ROMs. Primarily stick with leankernel.
