This is an unusual problem. I am using a 2GB Sandisk MicroSD card on my G3 running a slightly modified version of DDJP2. The problem i am facing is that i can neither delete the contents of my MicroSD Card nor format it. Here are the steps i took:
1) Tried deleting folders individually as well as batch-wise
2) Unmounted & Formatted SD Card from Phone
3) Connected to a PC running XP SP3 (Both in Kies & Mass Storage mode) and tried to delete / format
4) Tried both quick format as well as the total format
5) Flashed different firmwares, wiped cache/data, hard reset and then formatted
In all the above cases, when i re-checked the SD Card, i could all the original files available on the card. Surprisingly, all the folders e.g. the music/songs folder was working fine.
Deleting the folder(s) shows that the content is write-protected; therefore it is probably not letting me delete or format the contents. While searching for possible solutions i came across some (unique?) methods -
1) Flipping the "write' switch -- Not possible since i do not use an adapter and the MicroSD hasnt got one built-in
2) Taping a notch - Wasnt sure what that meant exactly
3) Try formatting the MicroSD in a Camera - Eh ?
Anyone could possibly enlighten me on how to remove the write-protection on my MicroSD w/o using any kind of external device and possibly by software manipulation only ?
I am too having this exact problem. it's a 8gb micro sdhc.
have you solved it or it was a malfunction on the card?
maybe you should try formating it in cwm?

cwm--clockworkmod recovery.
if you have extended power menu you can enter in it by that way....if not...power off phone..then...hold volume + and - together and press home key and then power on key...hold them together until samsung logo appears then let them go...phone will boot in cwm recovery mode...

the problem is that I don't have a samsung phone. only posted here because os a google search about my problem.
although I have an htc magic 32a but I don't know if I can do that here...
No, i couldnt solve the problem and replaced the card. Although my folders on the "defective" card work fine and i can even transfer them via bluetooth. I must admit i didnt try CWM wipe at that time although i did try advanced wiping softwares via PC. For flashing CWM or a CWM enabled kernel please visit your phone's sub-section on XDA. You must flash CWM on your phone, mot only to try the wipe but also to make a backup of your phone's image in case it gets corrupted and you need to restore it

Tried this on an Htc Magic with clockwork recovery installed. tried to format /sdcard but got error:
"error mounting /sdcard!
skipping format...
done"
tried also partitioning sd card but got error too.
and btw the previous filesystem is exfat so that is why it can't be mounted in android.
anyway also tried formatting in gparted and macintosh. both failed.

hope someone already solve this problem.. .
or else my 16gb micro sd will be gone to waste
I tried all of the possible things on the net.. .

The camera suggestion (formatting after putting in a digital camera) did the trick for me, good idea! It gave me a new set of DCIM folders, but I can pop it into my PC now and just delete them. Seems ridiculous that my camera can do it but my PC can't.
After the root procedure I don't seem to have any ability to use USB Mass storage.
Windows reports it as an empty drive, linux will show the device as connecting and assigns it a /dev/sdx device, but when you attempt to mount or fdisk, it reports no medium.
Any one else having similar issues?
I could always try a reset to factory defaults after unrooting, but I really don't see what rooting could have done.
I used the manual method and had to run zerg several times, however beyond that no other files where modified.
I've already reverted /data/local.prop to stock, no help.
Any one have any other insights?
I had to uninstall motohelper to get USB mass storage working.

When you take a picture, does it save to your sdcard? Sounds completely unrelated huh? Well, this phone seems to have an issue with the sdcard randomly becoming read only. I have had that issue multiple times now and usually it's solved by restarting the phone. Well, I seen your issue today and didn't remember if I had tried to use it as mass storage since rooting it so I tried....no luck. Took a pic, it looked like it saved, didn't get any error, but could not find the pic in my gallery. Then I tried to take a screenshot and got the read only error. So I just took my sdcard out and made a copy of it to my pc, put it back in and rebooted my phone, it's all good now, imagine that. Needless to say, i'm backing up all my apps right now before doing anything else. Then gonna backup my contacts too.
motohelper... Sounds like a stock app...
did you just rm the apk?

No.motohelper was a bs program that got installed to my PC when I downloaded and installed the driver pack from Motorola. Until
I uninstalled it I couldn't get USB mass storage to work.phone portal would,but not storage.

I had to reinstall all the drivers through motohelper to get it to work as well =/
No problems now though~
I was able to get my sdcard recognized again but still could not use it as mass storage device, never had a problem with this before root. Did factory reset and all is well.
There is no possible way root caused the issue at all. It stopped working for me once I installed moto drivers, but shows the device with mass storage under it in usb portal mode.

Well then it's one hell of a coincidence! Before root, w/motodrivers, worked fine, after root w/motodrivers, didn't work, after unrooting, w/motordrivers, works again.
Same thing happened with my phone. Actually now returned because of all the issues I kept having hardware wise and wound up going and getting the HTC Vivid. So if any of yall switch I will see you when a Forum is made for this device.

I have until the 24th of this month to decide if I want to keep this phone or not. I unrooted yesterday, will see how it goes this week. I'm not trying to pay big money for a phone right now so we'll see how it plays out.
OK I give up. The problem is intermittent. I'm going to do a log cat next time cause I'm getting about irritated. SOme times it works fine some times not. I've not unrooted or changed anything since the initial problem.
The only thing I can possibly thing is that some of the commands installed by busybox is screwing up the works.
Short of that nothing REALLY changes that could affect the operation of the phone.
What doesn't bare that idea out however is the fact that it EVER works.
**STUMPED**
It does the exact same thing on a completely unmodified phone. Therefore, it's nothing you did to it that's cause the problem.
I have the same thing on mine but it was something with the format of the card.
I flipped it to windows media sync mode then backed up the card and after the backup I unmounted the card and let the atrix format it.
I had the card in a atrix 1 before I put it in the atrix 2 so I do not know if this is the case or not.
This has now been working with out a problem for 4 days now
Same thing happened to my phone, I never rooted it.
Confirmed user error.

Thank you seraphielx! Shortly before finding this thead, I'd noticed that I had a rather large number of files in the LOST.DIR on my SDcard. Which coincided with the seemingly random disappearance of some of the apps I'd moved there. And when I pulled the SDcard to back it up on my PC, there were nearly 600mb worth of files in the LOST.DIR. Most of which were photos, plus (I think) some apps. Thank God I make regular backups!
I believe the problem, at least in my case, has to do with the fact that I could pull the SDcard without first pulling the battery; which I did when I swapped the stock 2gb card for my 32gb card right after I bought the phone. Thus corrupting many files, and probably the file system on the card as well.
After backing up what remained of my storage files, I tried to format the SDcard in the Atrix2, but It wouldn't let me select the option to format, and neither could I unmount the SDcard. So I powered down the phone, pulled the card and formatted it from my PC. Poped it back in the phone, powered up, and was then able to format it with the Atrix2. Since then I've had no issues with accessing usb mass storage, nor with disappearing apps and photos.
Thanx again for the assistance!
For me sometimes it takes a few minutes before I can access sdcard from PC.
Usually it works instantly after phone reboot while not plugged in pc, then it takes ages...

Update: OK, I can't unmount my SDcard, again. Which, of course, means I can't access usb mass storage anymore. The only I've changes made since my last post were to install some apps and change some status bar icons via Rom Toolbox, and I can't believe that has anything with the issue.
If I do a factory reset, will I need to root again?
If you have any apps installed on your SD card you will continue to have problems.
My ext. Card (32gb sandisk ultra micro SD) constantly corrupts random files. I don't think it is the card because this is the third card I've used with the same results. I can however use the card on my laptop and it works perfectly fine via the card adapter. If I put music or movies on the card from the laptop and try to use it on my phone the file won't work or works for a few seconds then stops. Also, when I save to my phones internal memory it works fine. Has anyone else had issue? I've tried factory resets and custom ROMs but its always the same result. ANY input would be greatly appreciated.
Don't install custom ROMs on top of each other.

Tried it and it didnt help. I tried putting some files on my phones ext sdcard via usb cable from my laptop but it freezes in mid transfer. Also when I tried to make a Backup with CWM it wouldnt complete. So i wiped/formatted and fresh installed stock rom again and installed TWRP with the same results. I think its time to just give up. Also when I try and install SUPER USER it gets stuck in a boot loop. Frustrating.
ideas anyone
Okay I was able to flash cm10.1.2 and super user with twrp. Its crazy I can transfer media to the internal storage just fine but not to the SD card. I've factory reset with twrp and reinstalled stock and nothing seems to fix this.

I'm so glad someone has posted this issue, I can confirm it does exist on stock Rogers RUXUMA ROM with an external Sandisk 64GB class 10 card.
The problem especially occurs when downloading compressed files from the internet. They appear fine but when you try to extract them, they have CRC failures. Sometimes they are fine until you reboot the phone.
I have been trying to troubleshoot this issue for months, its a problem with MTP or exFat on this particular phone. I've tried both CWM and TWRP, no success. The old Gingerbread ROM which didn't have MTP or exFAT support works fine, I've gone back and tried dozens of times.
I'm just surprised nobody else has reported this.
Hello folks, yesterday I installed 4.2.2 update (ubranded with MG8 ending, i9105p), everything is working fine, with exception to my SD card.
In Settings -> Storage it doesn’t shows up, and the "mount" button is greyed out, just like no card was inserted. The SD card itself is working (checked on other devices), it uses FAT partition (I even tried to re-formate it) and, since the Recovery can acces (and eventualy flash files) from it, Android OS doesn’t see it. I tried mounting via ADB but I have no previous experience with it. I also tried wiping cache.
I’m gonna try re-flashing another firmware tommorow, I hope it will work. :cyclops:
But is there any easier way to fix it? Thx
UPDATE: The card was working fine after re-flashing, but sometimes when copying files on it, File manager hangs, and files wont copy. This issue also unmounts the SD and makes it unable to be mounted until you restart. Propably some sort of kernel issue? (According to testing and 1+ year of trouble-free expirience with the card on another device this doesnt look like a malfunctionic card)
First post, sorry if this isn't the correct place to start the thread
Alright so I'm running resurrection remix 6.1.0 rom on my rooted oneplus 3T (android version 8.1.0)
The other day, I was trying to input a usb otg into my phone but it would not recognise. Searched all over the settings but there were no options for the usb otg (didnt seem like RRemix supported it)
Now what I did next was kinda stupid on my part, so after searching over the internet and various forums, I tried two approaches
First one was to go to the terminal, entered 'su' to get root access and entered 'sm set-force-adoptable true'
Now I'll admit that I didn't know what this command was at that time, but it still didn't make my phone recognise the otg usb
Next I installed the StickMount app from playstore, mounted the mass storage, but again didnt make my phone recognise the otg usb
But then the problems started to arise, and note that I had enough internal storage (60%)
First I couldnt update some apps (says not enough storage while 11% through download)
Couldnt take pictures nor screenshots (again says no storage)
Also couldnt delete any files Ive downloaded through the default file app ( but can delete any apps)
However I could still download new apps or new files from the internet
So I'm guessing I stuffed up the SD card/ internal storage systems. I was thinking of flashing the RR rom again and starting the phone fresh but that would be a waste of time as I have to set up everything again
I have also tried the command 'sm set-force-adoptable false' but no success
So I'm wondering, are there any ways of undoing whatever I just did, without having to wipe everything and restart??
Thank you so much for any replies, I'll make sure to know what I'm doing in the future before I follow instructions on the net haha
also just curious, but would greatly appreciate if someone could tell me what I just did, searched over the internet but couldnt find a precise answer. My phone also does not have an external SD card
What you did was tell the device to use an external storage device as part of the Interminal storage.
You will have to start over from scratch. Make sure to back everything up.
What you want to do is part of their closed sources rom. I have never had a single aosp based roms with otg.

Luckily I decided to do a reboot and super glad it fixed everything. Camera app works perfectly and my phone can recognise my storage again
