sd card constant error - Defy General

hello i have problem with my sd card so its operational but sometimes after a while camera gallery and file manager dosent see the card, gameloft games work, in dmesg it shows io errors in many sectors, flaweless with pc. so it is faulty microsd or not? i tried sd card formatter, then it writes blank or unsupported sd card? still testing but would like to get asolution if anyone succeded so far.
thanks!

If it is a class 10 card then it will never work, get a class 6 or lower.

its class 6 silicon power. any brand that is surely good? i heard the least problems about class 4 kingstones?

SD Card Issues

I have been having problems switching from a 4gb sd card to a 32gb sd card in my htc one v. The 4 gig runs perfectly fine in my phone but I need more space so I switched to the 32gb card.
The problem I am having is almost instantly after putting in the 32gb card my phone starts lagging on just about everything. Load times take longer, the phone has more graphical glitches etc. I tried formatting the card to nfts and running paragon software to use that file type. Still no hope. I also partitioned the card to 16gb and free space for the other half and still no luck really. Though I did see some improvement.
Is it just that I got a bad sd card? Note that it works with my laptop and also in my pc perfectly fine, the phone just seems to not like the card or larger file size. Has anyone else gotten a 32gb sd card to work in their htc one v?
Thanks
Derek
Yes my 32 gb transcend class 4 works perfectly,no lags,try formatting it with fat32 with the help of your pc like I told you once before.

I have an ADATA 32gb class 10 card. I will try that
Edit: Ever since I tried partitioning the sd card with MiniTool Partition Wizard the card won't show up on my pc. The software says that it is a (Bad Disk). Note that I can use the card perfectly fine on my macbook pro and the phone also recognizes the card. If I put the card into my phone and connect with USB it works fine.

[Q] microSD problem

Hello,
around 20th June i've bought a Kingston 32GB Class 10 microSD.
Everything was working correctly, and all my games were running like a charm.
Then suddenly all files became corrupted, and after reboot card became unreadable.
However i managed to read the microSD by formatting it to exFAT through CWM.
I also fixed filesystem errors through chkdsk.
And there's my problem: I'm experiencing frequent graphics freezing in nearly all games (mostly in GTA SA), where they weren't present before data corrupt.
Seems like the reading speed got slower or something.
Anybody experienced similar problems or know the solution?

May be the problem is from the sd card speed . did u put a higher speed to sd card ( default is 128 kb/s ) if not u can check an app called rom toolbox that has an option to higher up or slow down the speed and check if the speed is more than 1028 kb ( the safest maximum for class 10 sd card ) and if it is 128 kb higher it up to 512 kb or so . if it didn't work try to format sd card on pc with sd card reader not with the phone and if this didn't work ur sd card is dead ....

It was 512kb. Boosting to 1024kb gave nothing.

Issue with SD Card

I have Xolo Q1010i with Kitkat 4.4.2(Stock ROM with S009 update). Initially I was using class 4 8GB SD Card which was working smoothly.
Later due to higher memory need, I tried to use 16 GB class 10 SD Card (Transcend). For some time it was working smoothly. However I have seen notifications such as SD Card removed unexpectedly or SD Card is damaged and so on. The phone does not recognise the sd card later. I have to restart the phone to recognise the sd card.
Of late, I have almost 2.5GB available memory in the sd card and the issue is affecting me too frequently(atleast 10 times a day). The same card works fine on other phones(Android).
Has anybody come across this issue and has any solution?
Thanks in advance,
Srinivasa Pradeep

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.
