Hey i have a 64gb micro sd sandisk ultra class 10 card and every time i start my phone i get "Preparing SD Card: Checking for errors" which hardly takes 15 to 20 seconds to finish on my friends s3 with a 64gb class ten card also. On my phone it takes close to 2 mins and i can not access the memory card till it finishes. Any ideas why it takes so long? Does anyone else here have a similar issue?

 

it says available 18.50 Gb.

 

both have about the same amount of data on them, formatted as Xfat which is required to read the card in the phone and both of us are rooted running the same omega 4.1.2 V36 Rom.

 

have not tried that but going to give it a try next time and see.

 

i was checking i am running siyah kernel and my friend is running the stock kernel. I have all my mp3's in a single folder. Easiest way would be to try putting his mmc into my phone and see how quickly it reads. I had seen an app that reads the speeds of the card. I tried the sandisk memory zone app speed test it shows at 11.6MB/sec. How would i go about changing the rate?

 

i downloaded and installed the app but the min i start the app it says unsupported device. I checked the settings and under I/O control it says read ahead buffer size its set to 128. So if i change the 128 to 2048 that would make solve my issue?

no wont meet that friend of mine till the weekend so cant check it till then.

 

i tried changing the setting from 128 to 2048 but no luck it still takes forever to read the card. i had the same number of songs on my 32gb card that i do now on the 64gb and it scanned in a few seconds. Let me try it wil a friends 64gb and see and take a call accordingly.

 

ya could be its a brand new card just got it a few days ago. Still going to try it in the friends phone just to make sure, maybe something to do with the formatting(xfat for 64gb) otherwise its not such a big issue i dont really turn my phone off much anyhow. Been rebooting quite a bit of late trying out 2 different roms so every time it boots into second rom i have to wait 2 mins before i can do anything.

 

cant afford to change the kernel as im dual booting. I downloaded an app called sd speed increase which lets u set the speed i changed it from 128 to 2048 but it didnt seem to make much of a difference. Link to app below

ok i tried the mmc in my friends phone and it took over 2 mins to read and his mmc in my phone took abt 10 seconds. So it seems to be some issue with either my mmc or some data on my mmc. Going to try formatting the mmc now and see how long it takes to read then will try copying data back 1 folder at a time and see when the issue arises.

 

well figured it out finally turns out to be the clockworkmod backup folder i have which was causing the read issue. Deleted the folder and its all working great now. Thanks Quickaudi for all ure help.
