How safe is data on MicroSD/SDHC?

Every once in a while I'm having the same sort of problem whith my storage card, whether it's MiniSD, MicroSD or SDHC. To be more precise some/all files disappear leaving nothing but some bloody FILE*.CHK files, which seem to be completely useless. I did some google-search and there seems to be no practical way of retrieving the lost data.
I'm curious: why is it happening in the first place and has anyone been successful in combatting this issue? (don't tell me about backups )

I have yet to have a problem with the mem card in my Kaiser. it is a 6Gb Sandisk. Do you have an off-brand?
My old HTC Sable had issues like you describe...

arent .chk files left over by scandisk on a windows box?
this could be due to not ejecting the hardware before removing it from the pc!
under what circumstances are you experiencing this

Yes when combatting this issue I find that handguns are useless and shotguns are all the rage. When trying to do the official combat I like to taunt the problem a bit with the pistol (which just makes it mad) and then go all out with the shot gun. It's always good to have someone else at your side with a missle launcher or something, ya know, for the hardcore combat.

.CHK files are recovered file fragments from Scandisk. I would try a low level format of your SD card and then reformat as FAT32 (for the love of ____, do not use NTFS). NTFS is not designed for removable media and will give you nothing but headaches.

How do you low level an SD card. You only really hear about that with SCSI drives now days, Or do you mean a full format?

im not sure that the post that says dont format ur sd card as ntfs is accurate, while it may be true that a windows mobile device will probably not recognise this disc at all, i use an sd card formatted as ntfs in a laptop with no problems!
try hdtune @ www.hdtune.com/ this might be useful!

You can use an SD card reader with a PC and use a program such as Boot/Nuke to do a DoD-certified erase of the contents.

You can format removable media with NTFS, but you need to be extremely careful since NTFS is constantly caching data from the drive. Unless you disable write-back caching or eject the card each time prior to removing it (which cannot be done on a phone), you run a high risk of corrupting the data on it.

The problem with NTFS on removable media seems to be a windows issue. Not sure if that is windows mobile as well but it also seems to be fixed in a service pack. If I were having problems I wouldn't be using something with user rights and permissions on a device that does nothing with that.

It's Sandisk SDHC 4GB

This is why I released my new software SD Sync Any Kaiser users tried it already? Currently only One way Sync (PPC -> Desktop) happens..

Forgot to mention when trying to fix this I used the windows disc-check utility, but initially problem started after I installed one of the games (Tomb Rider I think) and the battery power was down to 2-3% when I turned my Kaiser off. I couldn't access the programm files folder from ppc, and it was empty when I opened it on pc...except there was tombrider.exe left...

Hmmm, interestingly it doesn't display the file system in the properties menu like it would for the hard drives... but I'm pretty sure I didn't format the card...unless was formatted NTFS when first inserted in a device...

If you didn't format it, then it would be FAT32 formatted by default.

You installed the games in the MicroSD, right?
I experienced it twice, sorted out that it happens when I'm using an application that installed in the MicroSD and then turned the device off. The strange thing that it is only occurred when using a large sized and resource extensive application (especially games), it doesn't happen when using light application such as YahooGo!, MapKing, etc. I end up to install all apps in main memory, and lived peacefully (finger crossed)
I hoped someone could explain why this happen, even better cured it

Actually you still can save your files, it still there just with mixed up name and extention
1. Sort the file by it's file size, you could get an idea what file it was by it's size
2. Change the file extention according to what you think it supposed to be judging by its size, ie:
small file to *.txt and open it with notepad, read what's in it and change it to what it's supposed to be .pwi, .xls, etc
2 - 6 MB files to *.mp3
etc
I know it's painful especially with my 2GB data, also you cannot saved your application this way, but I saved my most recent and important data this way, for the rest I just have to satisfy with my 1 month old backup
If anyone could suggest better way, pleaseee let me know

Just happen again
[email protected]!!! me and my big mouth... it just happen again this morning, same thing, install app in storage card, device turned off and wham!
But this time I did some googling and found this utility really helpfull

Well, anyone could explain what caused it and how to prevent it?
Any information will be appreciated

Yes mate! Sounds very much like what happened here - after intstalling Tomb Rider (4-6MB) in the MicroSD I launched it and then soft reset - my program files vanished...And I dont think I could do anything about that, the .CHK files I got after running the checkdisc utility were all the same size - 32kb, something to do with the cluster size I think...
I guess the question of the cause and the way to prevent it remains open...

No one can help?
Anyone also experienced this problem? Please tell us your experience, who know we could sort out something

Try to transfer data thoruhg a card reader. Especially if it is a large amount like 3-5g of music. Moving data through the phone is fine in short bursts but I always founf it to be cleaner and faster through a card reader.

Man it sucked big time for so long but I was able to find a corrupted file on there and had to use File Assassin from Malwarebytes.org to delete it. Even then, it didn't want to go. I reformated it full fat and used the "slow" process that filled in 1's and 0's. It happened when I went to CM6.1 the first time.
Think I may have borked it myself during an bad install and then it would never work correctly. I use MiniTool Partition Wizard (I don't like GParted b/c you lose all your data. With MTPW, your FAT data is still there when you want to resize yout ext/swap) to set my partitions and once that was done, I would try to reinstall that same file. Wasn't until I figured out that it was causing so many problems, but it was the only ROM that would boot up. If I used it and then wanted to go to Wanhu or HM's ROMs (this was a few months ago), when I would restore those, it would break the partition and would never boot up. Wouldn't loop in the traditional sense where the animation would run then disappear and the run again, it would just continually run.
Not saying it is CM6 or anything like that, I just think I got a bad download or operator error and a corrupt file hit my card. I just reformatted to full Fat and no partitions and it works fine (for now). It was only the partitions that would not work. I would run MZor sd-ext test and it was horrible with all the errors it showed. I had been deciding to format full fat anyways and stay away from partitioning (I don't and never have used swap), and I have to say I think it is really better that way. I only have about 50+/-apps so my Dalvik isn't even close to filling up and half of them I don't even use.

OK thanks buddy! Looks like thats what I might have to do. So what would be the best method to move Apps over then with just fat32? If you have any advice for me I sure would appreciate it

On my wife's XT, i am just using the native Froyo app2sd (settings>manage apps>select app>move to sd [there is also an app in the market called Move2sd enabler that will move "non-movable" apps to the SD card]). Don't move any widgets to SD card though. On my Vibrant, I have't moved a single one over to the SD yet and have 1.5g left on internal.
FYI if you get an error when downloading an app from the market and it says,
"App not installed
Unknown Error-18"
Don't freak out, it is a known Froyo bug. All you have to do is plug your phone into your computer and look in the .Androidsecure folder (make sure you have show hidden folders checked on your PC) and delete this file.
smdl2tmp1.asec
You can do it through terminal on your phone too but sometimes it repopulates if you do it this way
su
rm mnt/secure/asec/smdl2tmp1.asec
Sorry for the thread hijack but it is kind of a fix for some SD problems.

the original microSD that came with the phone is kinda shady
mine had some problems, had to format it twice to get it working right
a friend of mine even worse, after a few use it died completely

[Q] Move apps to internal (USB) storage instead of removable SD card?

Hi all!
Is there any way to have apps being moved to the internal (USB) storage instead of the external removable SD card. IMHO, the latter is - as the name suggests - removable, thus you'd lose your apps, while the USB storage is always with the phone (at least until you break it)...
Besides the moral question, I'm facing two problems with the external SD card holding apps:
1. apparently, these get somehow corrupted. I move a bunch of (innocent, no widgets, no system stuff, ...) to the SD card. Works fine... until I reboot, then hell breaks lose: Everything crashes, to the point that the phone warm resets. And that over and over again without escape (did I say I love backups ).
2. I changed my card now and copied over the .android-secure folder contents from my old to the new card. Yet, Android doesn't recognize them and insists in that they are unavailable.

I've had similar issues with #1, however I suspect that my SD card is misreporting 32GB when it is really only 16GB (it was a cheap one from ebay - won't do that again!!)
Not sure with #2 as never tried it - maybe you need to reapply superuser permissions to them?

Agreed, never buy memory there. Often (especially if they are suspiciously cheap), it's stuff that didn't pass quality tests, sold by some that work at the factory, or as you said, fake sizes.
However, my card worked perfectly well for a year in other phones, thus I think it's OK. Must be something with the phone, hope it ain't a hardware problem, though.
No clue what is wrong with copying over. There are no permissions on fat, thus cant be that. However, it might have been something with the copy process, I had a bit of trouble there. I hope it works next time due…
However, I would really prefer to have all in internal storage, but apparently that cant be done, sigh.

[Q] 64GB HD Card on Lollipop ROM - What format should I use?

I have been trying to find the best method for getting a 64gb SD card to work with my phone, and it has not been all that successful. I have formatted in NTFS, exFat and FAT32, all with varying degrees of success. Either copying files over leads to data corruption, or I cannot write from and to the SD card when it is being accessed by my device. Any help would be greatly appreciated.
I am currently running CMPrime ROM v1.1Beta with the included kernel. I have also tried using it with Unnamed Kernel.

I just received my Samsung 64gb EVO MicroSDXC UHS-I card this morning. I popped it into my phone and it asked me to format before I could use it. So I clicked yes and then after that it just worked.
I am not sure what would be different for a custom rom as IU use the offical Lollipop 5.0.2. It shouldn't be much different though.

FAT32 is your best bet. I have a 64GB Lexar card formatted in FAT32 working fine with Titan Prime.
It's possible that something is wrong with the card. Does the card work fine in other devices? What brand is it?
Could also be a hardware issue with your phone, have you tried other cards?

Use fat32 no other file system

I bought a no-name SD card from a Chinese manufacturer, because I figured "why not." I know quality of SD cards vary across manufacturers, but since it's an established technology and relatively easy to make, I thought it'd be worth a chance. Some quick Google-Fu showed that it is not a completely isolated issue related to SD failure.
I have a 32gb card that I'm using without any issues. I'm asking specifically about 64gb, because 32gb seems to be the max size for external storage.

I usually give ROM info, because it is common courtesy for dev communities. I have read that formatting through the device only accomplishes a rather crude job, and that file structures can be unsound. I know FAT32 is the standard, but it is an old format that has size limitations.

I believe you should be able to use NTFS or exFAT with the kernal you're running, though I don't know if there might be any bugs or compatibility issues with some cards. If even FAT32 isn't working correctly, my suspicion if that you have a bad MicroSD card. As a rule of thumb I always buy brand name from reputable sources when it comes to microsd cards. I know those cheap ones look tempting, but the quality issues with them are legit, so it's a real crapshoot.
And yes, you'll run into the same old limitations with FAT32 in terms of file size, etc., but I use it anyway since it has the widest support across devices and I sometimes swap my cards.

I am inclined to call this a bad SD card, but I want to rule out all other possible reasons. Null Hypothesis and all that.
In terms of performance of FAT32, it is registered by the ROM, and it is visible in recovery. But my music files are not readable in Google Music or any other music app. I've tried moving them to /sdcard1/media/music and it is still balls. This kind of behavior leads me to think that it is an actual formatting issue.

Max file size for fat32 is 4GB-1byte. Should be not a problem unless you plan on putting e.g. large hd-movies on the card. Speed isn't affected by the partition type (actually it is, but it's negligible in this case). No-name sdcards are often manufactured with low quality check standards. They sell cards that would normaly get tossed into trash. I use a 64gb card with no problem whatsoever. On windows use http://www.easeus.com/partition-manager/ because windows will only allow up to 32gb. On linux use gparted.

I occasionally save audio recording/mixing sessions as OMF files, which can end up being really large, particularly if I export at 64-bit sampling and 96khz frequency. So the 4gb limit can be a bit annoying to deal with, in that regard.
I wasn't aware about the cheaper SDcards potentially being of b or failed stock. I'll probably buy a new card under a trusted brand, and report back.

Acquired a Sandisk MicroSDXC Ultra UHS-1 64gb card. Tried using it in my android phone. I am able to load files onto the SD card as before, but I still experienced the same issues with Media Scanner failing to account for my music files on External SD. Worse yet, my Titanium Backup files became corrupted when trying to access them via the device. I did a Nandroid Backup and tried a clean install to rule out any potential conflicts with my ROM, only to find that the issues remained, and the Nandroid disappeared from the TWRP backup folder.
At this point, I'm starting to think that it's an issue with the phone itself. WHY CAN I NOT HAVE 64GB OF SPACE, MOTO G!!!?

I bought a sandisk 64gb card off amazon on black Friday, immediately put it in my phone and let the device format it.
Later, I put the SD card in my computer so I could create a 2nd partition for ext4 storage.
The phone had formatted the card Fat32...has been working just fine since then.

When I try to mount the SD card in the phone, it does not register. It only works after I format to FAT32 using TWRP. So I will probably try that.
So 32gb in FAT32, then 32GB in Ext4, and leave back-ups/other files there?

64 card files wont all play
Hi I have a new moto g, I also put in a 64 sd card, while the music files seemed to play fine, video and other files the phone reads some of them not others, I put the same file internally and on the sd card and it reads the internal version of the file. I gather from this forum (though I may be wrong) I need format the sd card, I have no idea how to do that, any help would be appreciated.

My understanding is that, if you have a FAT32 SD Card, then larger files (4gb+) cannot be read. ExFAT and NFTS should solve this problem, but I am still dealing with issues of reliability with my card accessing my music files post-formatting.

Finally discovered the problem. I downloaded SD Insight from the Play Store, and I found that the SD cards I got off ebay were invalid (including the Sandisk SD Card). I picked up a PNY High Performance 64GB Micro Secure Digital Extended Capacity (microSDXC) Flash Media Card from a local computer store, and after formatting to FAT32, everything works.
Moral of the story: buy your **** from a store.

I'm currently using CM 14.1 20161225 with a 32 GB SD NTFS formatted and experiencing some weird problems with Camera/Gallery, Music, etc. when on the SD.
So before I go back to FAT32 on a 64 GB SD I now have I would like to ask if anyone can comfirm exFAT would be working fine on titan CM14.1 or LineageOS?

That's strange, i have no problems with mtp in win7, looks like win10 doesn't worth updating. Btw, i tried exFAT before and it strangely limited file size to 4 GB like in FAT32.

SD card read failure

Every so often I get an error saying the sd card is corrupt or not working or something, and photos or music on the card will not open. After a hard reset, it works fine. Is this common? The card is basically brand new but I suppose it could be that.

So I am having a lot of things acting weird. Apps not working, sd card failure... I need to do a hard reset about once a day now. It is becoming a little frustrating. Any suggestions?

So I opened up the sd and sim tray, took out the cards and put them back in. Seemed to fix the problem for a number of days. This morning I had the failure again and I opened the tray and I noticed that the SD was a little off... does anyone else have this problem? Of the card moving around? Any idea how to fix it?
I may just have a bad sd card, now that I think about it.

Thank you because now i know i am not the only one with this problem!

Hey actually I got a new sd card and it has ZERO problems now. Taking the card in and out was only a temperary fix. i think the real problem was a bad chip. I had the PNY 128gb one ($30) and now I am using the SanDisk 128gb one ($40). I would only buy SanDisk from now on.

Unlucky many people have the same problem and no, your sd card is good... there is something wrong with the hardware or software of the huwawei..

I'm having the same problem with my Huawei P9 lite, both the phone and the SD card Kingston32GB are new, i even bought another SD card because i thought the first one was bad, but the problem persist. I haven't found a solution yet.

I have the same problem. I do not think it is specific to the card. I think the card is dislodged and moves around in the card tray and thus gives the issues.
I wanted to but a new card as well, but think this will not solve the issues. I will try sticking the card in the slot somehow to see if that solves things....

I've had my P9 Lite for a month now, and I've only started getting the SD Card corrupt error since last night. Unmounting, and mounting it again fixed it briefly, but then I got the error again while trying to take a photo about an hour ago. I've just formatted the SD card to see if it will fix the problem. I'm hoping for the best.
Have any of you fixed the issue successfully?

I get this when I copy a large files to the microSD card, movies for example (1080P FLAC 4GB each or something). It still works fine though.

Just an update: My SD card gave in completely last night! :crying: It worked fine after formatting, without any errors, until it just stopped working, so I lost a few days of pictures. Anyway, the SD card isn't even being read in my laptop, so it's definitely a goner. I'm currently using a different memory card, to make sure that the same doesn't happen to that one, to make sure it's not my device corrupting the cards.

Sounds a lot like my issues.
After having the phone P9 lite for about half a year, i'm on my second sd card.
2 weeks ago, i had the message it was bad once or twice, but now my phone is acting weird. A few apps (Twitter, netflix, pokemon go) will just start and close instantly sometimes. Apps will just crash. And everytime i reboot my phone, all that has happened after the 6th of July is nowhere to be found on my SD card.
It took me a few days to realize I might have some problems.
But reading this thread i might invest in a new sd card before doing a factory reset.

Problem is from bad quality sd card not from the phone,exactly like u are connect usb flash to your computer,if sometimes u have problem with the usb flash ,u should blame the usb flash not your computer.your phone is just a reader,try to buy good quality sd card

Did the same thing happen to your first SD card? I actually only started getting the issue when I updated to Nougat. I noticed that when I reboot my phone, just before it switches off, I see the notification that the SD card was removed abruptly, so I think it could have something to do with the software that doesn't safely eject the SD card before the device restarts or shuts down. I might be wrong though, but it's just a theory. I don't restart my device too often, but when I sometimes insert my SD card into my card reader, I get a prompt to say my SD has errors, and needs to be scanned.

I had a Kingston one, something i consider good quality.
But you make a valid point and i'm currently looking around for a new one.
It seems that for now my problems are solved by an old one i had lying around.
Saw SanDisk being promoted.

No, it behaved quite differently. That escalated from one of two error messages in a week to multiple errors daily.
And it was really corrupted, couldn't format it on the pc or anything.
But how is your current card behaving? All is well?

I had a 32GB (Class 4) Kingston SD card as well, which is one of the brands Huawei recommends to do software updates with. I had that card for 4 years, if I remember correctly, and I've used it with 3 devices, including my P9 Lite, which was the only device it gave problems in (only after updating to Nougat).
At the moment it's still behaving. I got a 32GB Class 10 Sandisk a week or two after my previous post, and so far it's fine. Like I said earlier, when I put my SD card into my card reader, I get an error message to scan my SD card, which means my device doesn't eject my card correctly, before rebooting. I still believe it is either an issue with Nougat, or EMUI 5.0. Again, this is my theory, according to my personal experience.

For me the problem also seems to be solved in the mean time with a new sd card.
Don't know if i like your theory though, since it would mean it is just a matter of time.
On the other hand, google does not show that many complaints......
Time will tell I guess.

I don't like my theory either, lol, but today when I was taking photos, I tried viewing the photos within the camera app, but it took a while to load them, and my gallery app stopped responding. I'm hoping it doesn't have anything to do with the SD card though, but I can't help being sceptical.

I changed from Samsung to Sandisk, yesterday after os update same thing. Took out the card, apps default to internal storage and works. Reseller is no help say it's virus. I am sorry I gave up my Samsung edge. May be should have bought iPhone if only working wit internal storage.

I have an expensive SanDisk card and it's worked fine for over a year, just started happening to me too now though...
