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.

I've bought a 4 Gb Sd Card yesterday, when i inserted it in my pc it asks me to format the card (showing me a size of 3800 Mb c.a.), but after i've done it now my card seems to be only 950 Mb c.a..... I've tried almost everything looking for a solution on the web (for example format again, format again but by DOS, use Panasonic SD Formatter, etc) but nothing, i can't have the size setted to 4 Gb...
What can i do to solve this problem?
Basically you must have bought a fake 4g card that is actually 1g. You can use your ppc as a storage device (using wm5torage) to format it through the pc. If it still reports 950mb you will then know for sure that it is a 1g card. The vendors have a way to trick the card to initially report a higher capacity but you will experience data loss if you use it that way without reformatting to the actual capacity.
i have a problem , which don't think is ROM related but any help will be appreciated
i encounter very slow write speed to my sd card (cards....i have a class 6 Kingston 16 GB, and original samsung 8 GB class 4)
when i write down files the speed is about 2MB/s at the beggining but ends at about 500 KB/s
so there are about 4-5 hours since i started to copy back the data from my sd card (about 10 GB of data) and is not over
i mention that i formated my sd card
run chkdsk, chnage cluster size from 64KB to 8KB with no visible succes
last night i alo run a defrag on my sd card ...which took hours to perform
i also noticed that at small files write speed is much slower
I would appreciate a GOOD advice, because i'm tired of "opinions" and searching the forum & Google
A big Thank You with anticipation
Is this when you access it over your phone, or from a pc?

You should not defrag a SD Card.

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?
This is annoying... I`m trying to copy things from the internal storage to the SD card and the max speed is 1.5MB which drops off quickly to 0 .... waits... then copy's a bit more.. I mean 700MB from internal storage to SD made the phone reboot after 20 minutes and all it had copied was ~ 350MB
The SD card is a 64GB Samsung EVO so it's not a cheep version.
I also did a bench with A1 and got:
READ: 16.51MB
WRITE: 3.09MB
Reading the net it seams i should be getting way more then 2MB which pauses for 20 seconds then another burst.... it's weird
Maybe i did not format the SD correctly
I had a 128GB microSD card in my LG G3, a 128GB Samsung EVO Select microSD card. After only a year I was seeing slow read/write benchmark speeds (using A1 SD Bench) & was also seeing some lag so I replaced it with a 128GB Sandisk Extreme Pro. But the speed for the Sandisk is the same.
The app A1 SD Bench shows them both doing Read: 42MB/sec, Write: 38MB/sec. I've seen others that see speeds of 70MB/sec and higher. Both cards are formatted exFAT.
I'm concerned that maybe I've made tweaks using Trickster Mod that might have slowed the card down? Or could there be another reason? Thanks to anyone that can help.
I don't know what's causing that. I also had a problem with my LG G3 851 and the SD card. Basically the SD card died and I can't read anything from it nor reformat nor anything. It was a 128gb SanDisk, one of the faster ones, running Lineage OS 16.1. I ended up just figuring I didn't really need the SD card in my case. I'm sorry your's is running slow. All I can say is try to factory reset the phone back to stock and see if that solves the problem.
Factory reset ("saying a prayer") is too drastic a step and rarely solves anything, but I did solve the problem.
Using Desk Genius on my PC I created a single partition on the microSD card (Most people just format, you must create a partition first). Then using Windows 7 disk format I formatted the microSD card for exFAT, 128K cluster size. Now the microSD card flies!!!
It took me a full weekend of testing to come up with this. I tried using various tools to partition, and various tools to format, all with different cluster sizes. This gave me the best performance.
Tools included Disk Genius, EaseUS Partition Master, MiniTool Partition Wizard, Windows 7 built-in tools, and a lot more.
EDIT: I forgot to add, after formatting you need to go back into Disk Genius and do a 4K alignment check (it's in the Tools menu). Alignment to 4K boundaries prevents extra read/write cycles and improves performance.
If it fails 4K alignment then you need to partition and reformat all over again.
That's awesome! I'll keep that in mind if I go get another SD card some day. I didn't realize that the format could mess up the read/write speeds. I wonder if a wrong format made my SD card die. If I do get another SD card, this time I'll keep the receipt in case it stops working again. I had a PNY SD card die on me in my Surface 3 as well.
It's not just the reformat, you have to repartition as well. And I forgot to mention you need to check for 4K alignment too (I edited my OP).
