Micro SD Volitility

Hey guys,
I have a 2gb SanDisk Transflash Micro SD and have been having some serious stablity issues with it. Ever since I first got it, it would lose a file or two randomly. Not a big deal, except that it was a picture of my kids once - that sucked.
But anyway, this morning the entire card contents (all 1.58gb) I had spent days compiling was inaccessable! The card still shows that it is full, but none of the files or folders is visible in either file explorer or in my card reader on my laptop. FYI: I had eight programs and 7 games installed on it as well as some music and movies. I don't want to reformat the card and lose all that, but I am afraid that this is my only option. I also don't want to keep using a card that is a timebomb!!!
Has anyone else with an Artemis (or any other unit) had this issue before and been able to rectify it? Any advice would be much appreciated! I'd love to hear that this is just a defective card and not a problem with the Artemis frying cards!!!

Same issue here
I have the same with my xda orbit, I have a 2GB microsd and once in a while suddenly I cannot access the data anymore, the folders and files are looking corrupt.
What helps for me is, to take out the memorycard, insert it again and make sure it is tight in the lock. Then, when you switch it on again, the files should all be accessible again.
I was thinking it might be a problem that the card is not tight enough in the lock so it would lose the contact, so what I did is that I used a small pice of plastic a little thicker than the lock of the sim-card to give higher pressure on the memorycard under the battery. Until now it works fine for me, but I do not know if it is a solution yet, I will have to wait some more days to see if it really works like that.

These problems do sound like a hardware issue. I doubt its the PDA or Windows and too many people have problem with too many different sized cards to be the card. It does sound like the card is suffering from an intermittant contact, I would try as above and make sure its a tight fit.

I,ve same issue. New HTCP3300, new SanDisk 2Gb micro. Installed set of application and then in one day found on the card folders with garbage names (even could not delete them). Reformat the card and install everything again. In couple days same probllem - programms installed on card don't work, and I can see strange folders on the card. Suddenly I found one not changed name on card with stored attachments of e-mails (more than 500) - long opening - then opened and after return to root I fount everything in place. Everything OK.
Does somebody has any idea what's happend?
How to fix it?

I've had the same problem in my Trinity with a Kingston memory card. Finally gave up and tried a different brand of memory card and everything seems to be ok now. Definitely sounds like these two issues are related. On the Trinity forum the general consensus is that is may be a firmware problem causing compatibility issues with some memory cards.

I had the same problem a few mins ago, Luckily after a reset of the phone all of my files were readable again so I would imagine rather than the card being corrupt, maybe some allocation table gets messed up.
fingers crossed that it doesn't happen again!

I had the same problem
Transend micro SD 1gb

Hi,
Does this affect the MDA Compact 3, or just the P3300?
Regards

Just happened for the 2nd time with my 2GB sandisk card. A soft reset brought all of the files back so I suppose it's annoying rather than a big problem for me. Nice if O2 / HTC got it fixed though!

and my sandisk microSD 2gb card after formatting in P3300 has turned to 1gb

i had the same probleme

Hi spangelsaregreat
Same problem with the T-Mobile MDA Compact III. Comes standard with a 1GB micro-SD card from T-Mobile (Sandisk).
The complete Benelux Plus map directory was corrupt. Other files/directories on SD looked ok.
Couldn't delete the corrupt files, had to format the SD card in the MDA Vario-III.
Greetings, Ben...

I've had my MicroSD only a few days so far but I have not encountered this problem yet.
I took the pre-emtive action of cutting a small square of the MicroSD packaging (that awful lethal theft-proof stuff) and placing it on top of the MicroSD-caddy before I clipped the sim-caddy into place.
My previous attempts to put it directly on top of the MicroSD, underneath the metal clasp that holds it down, met with failure as - contrary to what I've read elsewhere - the clasp is actually a caddy into which you slip the MicroSD before closing- just like the sim... forcing it down on top of the MicroSD probably wouldn't do it much good.
Anyway, so far so good- I can only recommend you grab some nasty plastic shell packaging and butcher it, worth a try... surely?

Corrupt Sandisk MicroSD
Hi all
I have been at the receiving end of this too. I have had this memory card for almost a year in my qtek 8500. I had everything from business data, cv, client logs, tom tom, and more importantly loads of photos and vids of my baby boy.
The card did go weird and prevented my o2 orbit from booting up properly, it just locked up. Took me a short while to figure out that it was the card and after i removed it it booted fine. I put the card back in and presto all working again.
Just 10 minutes ago I checked out my tomtom and ¨no maps¨!!! After examining the card on my mac, pc and card reader it's screwed. All data gone. just a few 0 bite files and daft characters. Nothing left at all. I am very gutted about this. All business data backed up etc so no worries there but the photos guys!!! I will never get those baby pics back! :-( very upset about it and it's definitely the pissing orbit as no other problems in any other handset for almost a year!!!! :-(
Any solutions to this as I cannot possibly trust this machine to store my important data anymore. I would like the ability to be able to sync my public folders in outlook then i could at least drop data into there while out on the go for backup. I'm not a keen believer in having to plug my pda in my laptop all the time to back it up as I have over the air email etc and i want to avoid all that pap!
STILL TRYING TO GET TO TERMS WITH THIS LOSS :-(

I am starting to think it may be microSD. I recently got an 'M3 Simply' game programmer for the Nintendo DS Lite, it uses microSD. I was using a 2gb because I feared feeding it to my HTC and a 1gb should be enough, then it suddenly became unreadable and unmountable. It would not format either.
CE

Has anyone tried a data recovery program like R-Studio. It can recover files off formatted hard drives and I have used it successfully on my SD card when my Uni messed it up, similar sounding problems.Might work.........

I did and it didnt work. my corrupt microsd was unmountable.

MicroSD
Hum, having the same here...
No solution yet?

I've just got the same problem with my O2 Orbit and a SanDisk 2GB MicroSD Transflash.
I've possessed the device for 1 month and it had been fine until a week ago. At first the problem was strange characters appeared in folder and file names. I reset the device and saw everythings back as normal.
But this afternoon Program Files and My Documents folders disappeared on the storage card. Soft resetting this time does not help. System still shows unchanged volume of used memory so these are definitely still there.
The former issue is also being discussed in this forum: http://forum.xda-developers.com/showthread.php?t=285511, but I suppose they are the same. Apparently this is a systematic fault so O2 and HTC must have been notified. Hopefully a solution should soon be found.

SD card showing incorrect remainind space....

Gents, After just recently suffering the dreaded SD card corruption "fault" (now finally fixed - I hope - with the new .cab from HTC)and having to reformat and reinstall all my programs data etc to my Orbit, I have a new issue with my microSD card.......
When the 2GB Sandisk microSDcard is queried for properties with Pocket Mechanic and Resco Explorer 2007 it notes that it is 78% full, with with 1.49GB on the card. HOWEVER, there is only 0.508GB (for sure) on the card, and this is noted when viewed using properties from Pocket Explorer!
The card is formated as FAT16 with 512 bytes/sector.....
Any advise as to reconcille whats going on? Will I have to reformat to "release" the space? ....I have not tried to copy and fill the remaining space on the card to see if the difference is real or just made-up by Pocket Mechanic/Resco Explorer...I'm worried about corrupting the card and losing all my data (again, ) All advice gratefully received!!

....doesn't anyone have an idea?

My card (2 gb sandisk) is reading the same 1500 in use 500 free.....
Its as if the Orbit is reading it the wrong way round.....
Saying that its been stable enough, Ive added more progs and mp3s also installed things.
Touch wood it seems ok.......
I would also appreciate someone letting us know what the problem could be though.......

You could backup the card and then try reformatting it with various different cluster sizes until you hit the optimum remaining space. I can't even remember what cluster size I used when I did mine , but it did take me a couple of goes.
Anyone know what the optimum is?

Well...I did exactly that uniqueboy! Solved the issue with a card format!
i) Took card out of device and plugged into USB reader
ii) Copied files (everything!) to a safe area
iii) Formated as FAT32 using default/optimum using standard HD formatter
iv) Coppied accross files exactly as were previously there
V Presto, all worked OK
.....and the remain 1GB plus was freed up! Suspect the issue was with the funny format (Fat16) and cluster size I used to try and mitigate against SD card crash.
All is well that ends well!!

how to use 4 gb memory card in dopod 818pro

Hi,
I am using dopod 818pro. But whenever i use a 4gb(mainly kingstone SD memory card) memory card, it shows, "no memory card installed". But i can use 2gb memory card (any brand).
My config is as follows-
windows mobile 6.1 professional
processor- OMAP850-195MHz
memory- 50.02 mb
ROM version- 7.0.0.7 WWE
ROM DATE- 7/5/8
RADIO VERSION- 02.19.21
RAM size-64mb
So please help me to use 4 GB memory card.

SDHC
The HTC prophet doesn't support SDHC cards (over 2 Gig)!

i'm using non sdhc 4gb card from transcend. make sure your card is not sdhc...

oh yes, but you still need a driver
hey man, if you have a normal SD card with 4GB, it still will not just work ,you needed a driver of some sort, sorry, I had it, but changed my computer some months ago. Maybe someone else has it?

do you?? i just put the card in & my prophet recongnised it.

SD
I used to have MMC and I thought the disable power management would resolve my problem of getting my files disappearing from the card if the path 2 or more folders deep, but when I changed the card to a normal SD (2GB), I had the same problems happening sometimes (but not as frequently as before), but I'm getting another (harder) problem now. I'm saying harder because this seems to be very hard to track because it happens when it wants!!
sometimes the card works for several days without any issue, but sometimes I get a blank card. even though when I look at the status I see the used space and the free space, but when I open it with resco or file explorer it's just blank.
and I even got a worse problem (fortunately it happened only one time yet). since I set the ie and opera cash to the card, these programs created their temp folder on the card again, but everything else was totally erased! I used a recovery software to get my data back!!
as I said, it happened once, but the usual problem is I just see nothing on the card until I shut down, and boot my prophet again. and sometimes it doesn't work until I do this several times.
I think I've looked everywhere to find a solution for my problem, but I didn't find any real solution for it. I've tried several roms, several cards, always getting the same problem. I don't think it's a hardware issue because of its nature. I mean how could it be a hardware issue if the data disappears without even touching my phone? if there is a hardware issue I don't think the card would be recognized at all! or (at least) it won't be recognized after I move it (causing the weak or loose contacts - if any - to disconnect) however, I don't think it's true, because the contacts are clean and tight, and like all HTC devices, the SD slot is high quality.
if anyone can offer a real solution to my problem, then I'll say he/she is the one who enabled me get the full of my HTC Prophet!
So thank you in advance. whoever you are!

FroYo + ADB App2SD: Goodbye, Kingston microSDHC?

Good eveneing dear community
I realize that FroYo was a major leap forward for quite a few of us, especially those limited in phone storage (I'm talking about Nexus One and Desire owners in particular). However, I think there is something seriously wrong with those App2SD capabilities.
I recently got the impression that moving applications to SD storage is killing SD cards too fast. Just after the first official FroYo OTA, I discovered and used the posibility to force move applications to SD storage using ADB shell. The result was that virtually any application could be moved out of the phone's internal storage. So far, so good.
But considering that we get updates from the market every few hours, SD cards are under much more pressure now than they were designed to, aren't they? I'm saying this, because in the exact same configuration I mentioned above, my cards keep dying. Before the OTA, I bought an expensive class 10 Kingston microSDHC card and the performance was indeed remarkable. However, after the OTA and my ADB stunt, my card would get mounted as read-only every few days now. In addition to that, I can't run any applications on the card anymore and the entire system becomes unstable. Unmounting the card using the Android system settings is not possible and neither is formatting. Instead, my phone would sometimes reboot. At first I thought this was a problem with my Kingston SD.
When I ran some tests and did the same things with the official 4 GB card that shipped with my phone as well as with another 8 GB card that came with an older Nokia phone of mine I realized that it wasn't a problem specific to my Kingston card. All of them showed the exact same behavior. This is not just annoying, it also causes data loss, which in my case is unnacceptable!
Has anybody experienced the same? Is this a problem of Android 2.2 or is it just the way microSDHC works? What, besides mounting said damaged cards in a Laptop in attempt fix, can we do about it?
Thank you for any suggestions.
My next phone must have at least 8 GB of internal storage...

Define "dying".
If by dying you mean Android reports there's something wrong with your card, then more likely the problem is software-related rather than the SD being overused.
I got the "your card is fubar" message from my phone but it was as a result of me damaging the file system with a sketchy file manager app. I put it in my computer, did a scandisk. This found the problem, fixed it, I put it back in my phone, voila, perfect again.
Or your problem might be related to the method you're forcibly moving the apps to your SD card. Since you're doing it with ADB rather than through the operating system itself, it's possible apps are corrupting your card's file system as a result of not realizing where they're located. Just a guess.
In any case, SD cards don't (and won't) die from the sort of use you're describing. What might be harmful is storing frequently-used cache on your SD card, but that's not something that you're doing.
Keep in mind that SD cards are intended to be used in cameras, camcorders, etc, and these things write a lot more frequently and aggressively to the card than a little app storage here and there.
I'm not exactly an expert but I'm definitely what I'd call an enthusiast, and let me tell you with certainty: you really have nothing to worry about. Your problem is most likely a software (or related file system issue) or else caused by a one-in-a-thousand random hardware defect. Android, or more specifically, app to SD, isn't a problem.
Maybe you've heard of solid state drives for computers, these are becoming more common. I use one in fact. They operate using technology similar to SD card storage and if ANYTHING was going to stress these things, it would be running a whole computer off them, temp files and all.
Finally, if you're still a little afraid, let me remind you that in fact your phone itself uses the same kind of flash storage as an SD card. Every phone, MP3 player, and similar device does. So in a sense, if wearing out your storage is a concern for you, isn't it better to wear out a replaceable SD card than your phone's irreplaceable internal storage?
----
So now assuming you trust me that there's nothing to worry about, I would suggest you stop forcibly moving apps to your SD card as a possible long-term solution. If you stop getting card problems, you know what the problem was. Since this means you'll run low on storage, I'd then suggest you install a custom OS that allows you to force-move apps from within Android itself, such as Cyanogenmod.

I've been using this mod since it came out and have had no problems. As mentioned above it must be software related to your phone.
Sent from my HTC Desire

Thank you so much for calming me down. I just got the impression that my cards are toast. However, as long as there is a possibility to fix this using my laptop, I'm on the good side.
I disabled that ADB stunt, let's look what the next few days bring.

Just an idea: if your phone (or the sd slot, for that matter) would be somehow messed up, wouldn't that show the same symptoms? It would even explain why _every_ card acts that way. Maybe it's a bad contact in the slot, who knows...

How to configure sd card as internal - new phone

Dont recall how i did it on mine but my wife got an g4 as well and i got her an sd card, just cant remember how to configure it as internal memory. I added the card and sent her an image and it said it can't locate the image so obviously i didnt configure it correctly. Any help appreciated

I read configuring an SD card for internal storage use is very risky business if you care about the data on that card. Once configured, you cannot read the data in any manner on any other device. And you cannot retrieve data off the card if the phone goes bad. And write and read speeds are slower too.
So because the G4 is known for bootloop issues, this makes it that much more risky. If anything, would suggest backing up data often.

I dont have any issues with mine. Been using it for 6 months now. I can take the card out, use a card ready and see the contents of the card no issue. Just dont remember how and if i configured the card when i slid it in.
But i tried sending her a picture through whatsapp and it says cant find it on the sd card. As soon as we took it out it saves to internal phone memory and all ia good.
I do want to configure it for her. I do notice my card is 70% filling up and it does have a short delay with the message "saving" when i take a picture that wasnt there when it was empty but no complaints . I will just get a new card and hold the old one as archive. Better option then losing all of my media when my pos htc m7 fell in the sink. Ill take slow speed over no recovery any day. And i dont care for cloud.
