Broken sd card error - Lenovo P2 Questions & Answers

I bought 32gb sandisk sd card yesterday. It was fine after first partition. But after a while i started to get "broken sd" kart error and the sd card wasn't even on the storage section. After couple of reboots i finally was able to make partition again but the same thing started to happen over and over again. Sometimes there isn't even an error sd card just disappears. And when sd card works properly phone slows down a bit. Like after pressin power button screen won't open for 2-3 secs. What may be the issue here?
Someone said make partition on pc but i lost my card reader. Is there any other way to fix this issue?

question about sd card that erases by itself

i have a blue angel/sprint ppc 6600. almost every other night between the time i go to be and the time i wake up the sd card gets erased all by itself? i wake up in the morning and everything on it is gone? i make sure all the programs are closed when i put it down for the night. i cant figure it out? any ideas?
i have about 6 programs and some files on the 1 gig sandisk sd card. i have replaced the sd card and the problem continues.
thanks.
This worked for me - I don't know if this will work for you
I formatted my 512mb sdcard took it to fat32
I then ran scandisk and defrag on the card - there were lots of errors
after fixing that
I then reran the scandisk and defrag until all the errors were gone
I now back up my SD card every other day to my desktops Hard Drive

[Q] SD card suddenly not recognised and causing the phone to hang

Has this happened to anyone?
I am on GB. THe SD basically causes the phone to freeze when i try to access any of the settings. What are my options here? to reformat the card? i looked at the card on a laptop and the contents seemed ok. THe SD card is a sandisk Class 10 32GB card. I haven't installed any new apps for the past couple of weeks so i don't think this is a problem

I`d copy everything off the card to my hard drive , then reinsert the card into the phone and reformat it via the phone software , then let the phone set itself back up with the empty card and see if it works . But...that working around the issue (if it works) , the root cause I`d guess as a corrupted setting on the SD card . For the record , mine sometimes throws a stroppy (every couple of months) and says the card isnt there , the tried and tested turn off/on worked for me .
b/Have you copied any program across to the SD card ? I`d try copying them back to the phone

SD Card gets unmounted randomly

My SD card is constantly and randomly being unmounted and after a while it's mounted again. I've tried several ROM including stock, RR, and now using Bliss 6.0. Also tried 2 different SD cards, kingston and Sandisk 16 gb class 10. Also formatted the card several times.
Is it a hardware issue?
This could be. I get this with my Sandisk Class 10 card, it would just randomly go missing. However, I found out that (through with enough trial and error) if you take it out, and reinsert it with the OS still running, it shouldn't unmount again, just don't shut it down, but reboots are fine (this is at least what my temporary solution is)
The same problem happened for me with stock rom, a sandisk class 10 sd card too, and after some unfortunate falls...
Strange fact, the problem completely disappeared since I flashed cm13, and without doing physically anything to the sd card.
I just tried what pross8002 said, and effectively, booting from a shutdown + power on makes the sd card non mounted, while a simple reboot makes it normaly working.
just don't shut it down, but reboots are fine

SD card is always corrupted after 6.0 update.

My SD card is always corrupted. I tried using different SD cards even i bought a brand new SD card and it is still giving me issues . I did a factory reset and still does the same. Anyone else with the same issue?
What's the capacity and speed of your SD card? How are you formatting the SD card? Do you use it preformatted or format using the phone? The reason I'm asking is it seems to me that Sony has set a too low timeout values for formatting and mounting the SD card. So if your card is very big or not fast enough, the phone would timeout too early when formatting and/or mounting the SD card on boot, thus causing it to be detected as corrupted. At least that is how it seems on my phone.
perhaps have reset your phone from previous backup ? if this is the problem already happened to me ,
They are both high speed cards 10 cards Toshiba and Samsung to be more specific. When i format them they seem to kinda work at the beginning i even managed to copy a video file but after a phone restart it gets corrupted .
MM updated through xperia companion here, seems to be working normally with the old microsd card
Hi Team,
I also have the same issue here, whenever I move applications to SD card (Samsung Class 10), the application stops working and I have to
reboot the phone to have it running again. Though it happens only... when phone is from Doze mode, turned on the screen with power button, and after turning on mobile data and run the app like COC or Viber it crashes. Now this happens only, if my application is in SD, if it's on the phone it's working fine.
Hello everyone.
I also have this problem. I have a Sandisk ultra (red and grey) 32gb class 10 sd card, and my M5 on 6.0 cannot format it at all, first it says it's corrupted and I have to fix it, then the format screen is stuck on 20% and after a while it says the card cannot be formatted. The card isn't counterfeit, and it worked flawlessly in my m4. It was replaced under warranty because I presumed it became faulty, and I still have the same problem. There is no problem with it on my PC. Also the phone freezes when the card is removed and I have to turn it off with a paperclip on the small "off" button.
You have sd card restrictions on 6.0, so you can use it for media, can't move apps... I've got Transcend sd card class 10, no problem at all.
I know about the SD card restrictions but my card was working fine in 5.1 for storing photos and videos taken by the camera applications . Now i have tested even more cards and they all have the same behavior. Even with an 4GB and 8 GB Toshiba cards and an old 2GB transcend card.
tonev, how are you formatting the card?
On the phone it self. Also tried to format it on my laptop , Same result. Sometimes it works fine and after i restart my phone it gets corrupted again
any news or fix here? seems we're stuck with this sd behavior? can't really move apps to sd card?

Is it correct to assume that you restart the phone only using the default power menu and not using any third party interface?
Another thing, it is not advisable to format the SD card using Window's Format function. It is possible to damage the SD card this way. The safest way to format an SD card in Windows is by downloading and using the SDFormatter utility. I don't know if formatting you card in Windows is what has caused your SD card to be corrupted, but it is something to be considered.
Yes i do restart the phone only by using the default power button. menu. And none of my cards are corrupted because they work fine on other devices. As i said before a brand new never used genuine samsung SD card does not work on the phone.

External SD card gets unmounted when access it and then remounts

Hi,
Since recently i have the strange thing with my G3. When i insert an external SD card the phone reconige it. When any app wants to read it or write to it the card gets unmounted and directly back mounted. This happens with any app i use. As long as my phone is in standby (screen off) the cards remains mounted at all time because ther is no app using the SD card. But once I use my phone for example taking a picture bamm the card gets unmounted.
I tried everything from reformatting it in my laptop to rename the card to replace the sd card. I even tried another card but nothing happens.
I put my phone back to factory defaults but that does also no help.
Hardware issue?
