[Q] Micro SD not detected

This morning, my phone was normal. Using apps, making calls, no problems.
Then I noticed my ring tones and my notification tones wouldn't play. Since they are stored on the Micro SD card, I thought a reboot might solve the problem. After rebooting, I get the message "SD Card Damaged". So I took it out from my phone, plugged it into the computer through a USB MicroSD reader. It detects it, and from there I can see all the files stored on there.
I decided to run a Windows (7) error check test, as that usually fixes any sort of SD problem I've had. The check ran through successfully, saying it found some problems and fixed them. After that, I put it back in the phone, boot it up, but it still wouldn't access the card. Most of my apps are stored on there, so I wanted it fixed. I took out the card and ran it through windows error check once more, only this time, I checked the box "Scan for and attempt recovery of bad sectors" and hit start. Two hours later, I notice the progress bar hasn't budged from what I can only assume was 60-65%. I decided to hit "cancel" and look up some alternative methods.
Except as soon as I hit "Cancel", something went terribly wrong. The computer no longer acknowledged I had a MicroSD card inserted. I removed the USB adapter, removed the mSD, reinserted the mSD into the USB adapter, replugged the adapter in and -- same result. I restarted the computer, and while that cycle started, I placed the card back into the phone to see if it would detect it. No luck. By this time, the computer had restarted, and I tried to reinsert the card. It detects the USB Adapter, but it's as though there was no card inserted.
At this time, I scoured the web and countless forums (including these @ xda) with no avail. I tried nearly 10 different applications built solely for data extraction, but they all had the same problem: they couldn't detect the MicroSD card. My fellow I.T. coworker suggested using an Ubuntu Live CD and try their diagnostic tools; it couldn't detect it either.
Here are the specs of my setup:
Phone: HTC Desire CDMA (USCC)
Rom: Phoenix 1.4 BravoC
Card: Samsung 8GB Class 2 MicroSD (stock from US Celluar)​At this point, all I'm really concerned about it just retrieving my lost data. I have important sentimental photos, and more importantly, I have important flash backups from my stock rom that I would need if I want to return my phone for warranty. Physically, the card is undamaged. No dust, no cracks, no wear & tear. Hours of googling "SD card not detected; data recovery" leads me to several unanswered problems and fake websites baiting computer illiterate people into downloading malicious software.
I've heard of solutions that involve sending a card in to have repaired, but in turn, shelling out a couple hundred. Now I'm not stupid when it comes to computers, but I'm not necessarily a genius either. I've tried several ways to circumvent this lockout issue, and I can't find any way to undo a process from the Windows error checker. Hell, I can't find any cases or threads pertaining to people having bigger problems because of the error checker.
So I call out to anyone who can help. I can buy a new card, no problem. I just need my data back. It's crucial for my phone and important for me and my memories.
Any suggestions?

Hi
My phone:
Disire HD (GSM)
Android 2.3.3
CyanogenMod 7.0.0 RC2
I had the same problem as you a few weeks ago(my phone wasn't rooted) ....
Tried different methodes to get my data back, they all didn't work.
The problem is not the phone or any app on it neither your roms are the problem,
searched the internet... and came to the solution that I was not alone with this problem. they assume this is an hardware fould in the SD card ( btw its weird that its an Samsung SD, didn't you thought the same I still dont understand...)
Anyway, my solution was going back to the shop where I got the phone (Belcompany NL) and ask there solution for the problem i lost all my pics and other importand crap haha..
They didn't had a solution or something, just giving me a new one.. so I got a new SD Card (for free )
But lost all my data

You know if a partition messes up, which it has done because you didn't let it finish, there is like 0% chance that you can recover any data on your SD card. You should of backed your card up before you attempted to even start doing a disk check. As for getting your SD back up and running, you can try gparted live cd and see if it will detect it in that. If so just repartition it, but next time, let it do a thorough disk check and finish. Checks can take hours and hours because it is doing something. Just backup your SD card frequently.

I've decided to purchase a new card rather than hassle with unrooting my phone for the sake of going back to the USCellular repair (on just a whim that they may replace the card).
I've heard that I need to be careful when choosing a brand of MicroSD cards. Transcend is a no go. But what about this: An 8GB A-DATA Class 6 MicroSD card?
From what I've gathered, A-DATA is a reputable brand, and it shouldn't really cause problems in my HTC Desire, right?

SD Card issue

Hi, I seem to be having an odd problem with my Desire, I'm running a Stock Desire on T-Mobile UK, using the SD card that came with the phone, I had no problems until yesterday when the phone reported that no SD card was in it, it is acting as if no card is in it at all when using the Samsung card that came with it. First thing I tried was to put the Micro SD card in my Laptop, it worked, could read the files, so I was worried that the card reader on the phone had gone, they I found an old Nokia 512 MB card and tried that in the desire, it worked fine, no problems, so I'm not quiet sure what to do from here.
I was thinking backup the micro SD that came with the phone, format it in windows, and then see if it works, one question, what would be the best way to back it up?, are there hidden files that require extra software rather than just dragging and dropping in windows?
If not then I will buy a new SD and hope that works.
Thanks for any help
PS. I don't know if this is in the wrong section, so sorry if it is.

Since it can't read the card anymore, you can't backup apps. Format it with Android, or use SDFormatter.

[Q] SD Card Issues?

Hello everyone,
I just recently purchased a Samsung Galaxy Tab Pro 8.4. So far I really like it but I am having a problem. I have a 32 gig sd card plugged in and yesterday I tried putting some files on. Nothing fancy just music, a video, a couple kindle books, and some word documents. I had plugged the sd card into my computer dropped them on and put it back into my device. Well the device wouldn't find or acknowledge any of the files at all. It acted like they just didn't exist. So I plugged the sd card back into my computer and they were there. After a bit of rebooting my device I finally got it to acknowledge the stuff I put on. That lasted until I let the device go to sleep. This morning when I opened up my device everything was gone again. So I plugged it back into my computer and it was all actually deleted.
After that I tried putt stuff on it with the device tethered to my computer and the same thing happened. It wouldn't acknowledge anything kept on my sd card. Including kindle books.
I did some reading and just kept coming up with the kitkat and app compatibility issue that doesn't allow apps to save to sd but this doesn't seem like that. All of those posts seemed to be dated a few months ago so has that been fixed at all or is it still a problem and the only "fix" is rooting it? Is it related to the problem I seem to be having? If not what on earth is worng with it and how do I fix it?
I won't lie I am kind of a newb when it comes to anything beyond basic electronic issues so I really am at a loss for what is wrong with it.
Thank you in advance for any help.

P.s. Should I consider returning this tablet? The stuff I read about the kitkat seems like a huge problem when it has such a small amount of on board space. I have just basic stuff on it and still only have 6 gig on board left over. That means basically all storage will be on an sd card. I bought it to use for college so want to be able to take notes and reliably save stuff. Am I better off with a different tablet? If so what Android tablets would be best?

Any rooted tab is better.. Rooting it will allow you to fix your SD permission woes. More than likely the app you are using can't get access to the SD card thus why it shows up blank. Root the tab, and run the kitkat SD card fix app and never look back. This tab is great!

So basically it will always have the sd card issues thanks to kitkat? I tried opening the music and the video with the devices main video and music apps. But they also weren't showing at all when I went to look for them in the actual "My Files" section. Then when they totally deleted I got even more confused. It was 5 gigs of stuff just randomly deleted off the flash drive.
Is rooting hard? As mentioned I am a newb. I have never done anything like that and I have never used or worked with a rooted device. Won't it void the warranty and make it so I cant return it? It was fairly expensive so I am worried about ruining it haha.
I actually love the tablet so far so really disappointed with the issue. I have until the 14th of August to return it so I need to decide quickly.

Some people on this forum have reported that towelroot works on Tab Pro 8.4. It should be as easy as installing an apk and tapping a button. I already have CM11 installed so I didn't try it though..

Hi
I'm not new in flashing ROMs but I think somewhere I go wrong...
I had the Australian stock ROM and I thought to try a little bit de-bloated ROM to check if its better...
As I'm ALWAYS doing I did make a recovery full backup of my tablet and copied the TWRP Backup in my Ext. SDCard with the intention to move it in my PC for security. Reading how to flash the new ROMs, couple of times have been mentioned that I have to wipe EVERYTHING before I flash them... Against my better judgment I wiped my SDCard too and of course I wiped the new ROM too...
Oh well I thought I will restore my Backup and try again
1) TWRP did NOT read the backup from Ext. SDCard.
2) I d/l an Aussie ROM from SAMIFILES to start again and copy the TWRP Backup in SDCard in case something wrong etc...
Then All Hell Break loose
After Flashing the Full factory ROM I had in my tablet few only apps without ANY Google apps and I couldn't access my Ext SDCard...
When I took out the card to copy it in my PC and from there to tablet the card was corrupted loosing my original Backup...
After that I don't know how many times I've tried factory or XDA ROMs with all the time not able to access my Ext. SDCard (New one, works fine elsewhere) despite I tried ALL the SDFix apps in Playstore... I tried to change the properties of the card manually too but the same...
PLEASE can help me to Fix my Ext SDCard as the tablet is almost useless without it?...

have you tried copying the files to your main memory, then transfer those files from main memory to your memory card using the built in File Manager ?

There is a lot of misinformation and misunderstanding about the SD card permission changes brought by KitKat, and I do not believe the OP's issues are caused by those changes. We are unfortunately to the point where if someone has any trouble at all with an SD, they blame the KitKat permission changes; which is simply false in many cases. The KitKat SD changes have to do solely with write permission access and do not affect the ability to read the SD. The following article explains it well:
http://www.androidcentral.com/kitkat-sdcard-changes
And the KitKat changes certainly would not cause the card to be read after a reboot, then randomly not readable later, as the OP described. All this is pointing toward an issue other than how KitKat handles SDs.
I would suggest re-formatting the SD to FAT32 (on that subject, what is it presently formatted to?) and seeing if that helps. I saw a very similar thread on the HTC One (M8) forum where the person was having trouble with the phone reading content on the SD (worked fine on other devices), was blaming the KitKat rule changes, and simply formatting the card fixed it right up. Also, try a different SD card, if you have access to one.
If that doesn't work, its possible where is some software or (hopefully not) hardware issue such as a broken SD tray. But let's try to format the card and see if that does the trick.

Sorry if I didn't make myself clear... I CAN see the Ext.SD but I can NOT write... The card (2nd) it's empty and I can write in it files in my PC's Card reader which I can see in my tablet... I CAN NOT write a file or make a folder or anything when the card it is inside the tablet...
That's why I said the tablet it is almost useless as I can use only the native 16GB minus...
EDIT:
Problem SOLVED for whoever need to know how go here: http://winaero.com/blog/unlock-external-sd-card-writing-for-all-apps-in-android-4-4-kitkat/

Thank you guys for the help so far. Sorry I am a bit slow but my laptop died on me and I have been dealing with that.
I am glad to hear its more than likely just an sd card problem not the kitkat problem. I really don't want to root it. I actually adore this device and don't want to had to return it.
I have played with it more and I am getting stuff like pictures and videos taken on the device to save to sd so it is reading the sd card. It just wont read what is placed on it externally. Is is maybe that I have to tether and cant pull the sd card out?
I did reformat the sd card with the device. So it is formatted to the device. But it still wont acknowledge stuff I drop on it only stuff that is saved on it from the device itself. But I do know its working because its showing pictures I have taken with the device on the sd card in the built in file manager. So whatever it is it's not the card reader slot.
I am going to try xdm9mm's suggestion and see if that will work. If not what else should I try?
Before I can test another sd card I need to buy one (I looked and only had the one extra lying around). So what card do you guys use on it with success?

You're taking the card out and using a card reader? I think I know your problem, the same thing happened to me when swapping cards with my phone. You have to go into the system settings, and under general, select storage. From there you can unmount the microSD card before taking it out. If you don't do that, it won't read the card properly when you put it back in.

Every time I have taken it out I have used the unmount section. Originally I unmounted it put it in the adapter and plugged it into my computer. Then I dragged and dropped everything I wanted on it to it. Once I had done that I used "safely remove" on the computer and then plugged it back into the card reader on my tablet. That is when it wouldn't read anything at all. I reset it several times and finally got it to read for a minute but then when the tablet went to sleep it self deleted everything on the card. I am thinking the self deleting may be fluke because I have been able to save pictures taken by the device on it with no trouble. It just won't read anything I put on myself.
The whole thing is a bit confusing lol. I even took it to a computer shop in town but the guy had no clue what I was trying to explain. I am going to try another sd card and try tethering the device to the computer to drop in some new files. Hopefully that will help.

Hrm. Another possibility, have you tried filling up the card, say with video files, then checking from the PC to see if they all play? Most of the really cheap memory cards are fake (including on Amazon), they only have a tiny capacity, and the controller is set up to loop, so it will write the data without giving any errors, and the files will be indexed, but the data isn't actually saved anywhere.

SD card periodically damaged

Does anyone else have issues with their SD card being "damaged" by the device? So far, I've learned that moving any app to my SD card will damage it. So I was storing only media...pictures and videos on it. This morning I learned that updating the Samsung Push appears to also damage it. By damage, I mean the device will no longer read it, but so far I've been able to reformat in some way or another, and use it. Either the device can reformat, or sometimes I have to take it out and reformat in my laptop.
I've tried 3 different sd cards so I know it's not a bad card. It's the device. I'm wondering what good an SD card is if I can't even store stuff there
Is there a fix?
I'm completely stock, not rooted, fully up to date on the sw releases.

Google made it where you can't use a SD card for things anymore. I know if your rooted there's apps that fix the problem and let you store whatever you want. So I doubt your SD card is messed up its just the restrictions Google made. I think you can only use it for some things. I have 128 gb card with all my game data on it and it works fine.

All files on external SD card corrupt after unexpected shutdown

Hey guys and girls!
This morning my phone turned off by itself (13% battery left) and needed somewhat longer than usual to reboot (in the meantime I plugged it back in to the charger). First thing I noticed was that my whole theme got reset as well as it started showing me introductional tips ("long press here to move your apps to the homescreen, ecc.). It also started to update apps in the Play Store even though I set it to manual ... so basically a LOT of things were reset.
The biggest problem I'm having now is though that all my files (pictures, videos, music) that are stored on an external micro SD card are corrupt. It's not possible anymore to open anything. I already removed the micro SD card and put it into an adapter to have a look at the files via the laptop. But nothing, even though the sizes of the files seem OK, I can't open them.
Does anyone have a clue as to what exactly happened here? Are those files lost (at least of some I have a backup) or is there anything I can do to "repair" them? Help is really appreciated, thanks!
PS: Things like the card unmounting and re-mounting never occurred. So I can't tell if the card was dying or if actually the phone ruined my files.

Did you happen to be using a SanDisk SD Card? I've had my 10 brick 2 of those until I switched to Samsung SD Cards about a year ago and haven't had issues since.
I never could manage to recover files from the damaged SD cards.

I have a Samsung SD card and had something similar.
I guess I was on Viper Rom and basically my phone restarted around 15-20% of battery. After a long wait for booting back again, all my settings were gone.
Files and others in the SD card was okay but basically until I formatted the card, I wasn't able to boot into the Download Mode to install a new rom...
I fixed the restart issue by installing the official HTC Rom.

Thanks for your replies.
It is indeed a SanDisk 16GB card. It seems though that the card is still working (no problems accessing it via phone or laptop), just the files appear to be broken. In the meantime I also tried apps like PC Inspector File Recovery, but to no success
I'm still on stock HTC Sense by the way, no root, nothing.
Anyone know though why that happened (resetting everything, etc.)?

Hit me with a PM I'll give you a SanDisk restore tool which works quite ok. there is a huge chance some files can be recovered, some will be damaged though. Don't push any new files on the card after you tried to restore the files

HTC 10-Corrupted microSD card
I know this is an older thread, but I was wondering if there is a solution. I have an HTC 10 which has an micro SD card in it, that is "married" to the phone. When connected to a computer, the computer recognizes the phone, and the microSD card, and begins to load the folders/files. Eventually this process stalls, and the phone/drive is no longer readable by the computer. To get the computer to recognize the phone/card again, I need to restart the phone, but the same thing happens again.
I have like 20gigs of data on the card, and cannot just put the card in a reader, because it's encrypted to the phone. Any possible solutions? It's frustrating to see the files/pictures for a minute or two, and then have them disappear. I have tried copying/pasting the files while they're visible, but this often triggers the computer to no longer recognize the phone/memory card. I've tried to un-encrypt the microSD card, but the phone can't recognize/access the microSD card long enough to complete that process.
Please help if you can.
