Well, I got a new Class 10 SD card, Transcend, from an online shop.
First few days it gave me great speeds. ~15mbps. Now, I'm getting not more than 4mbps!
I guess this happened mostly after using Data2SD or Partitioning the SD card
Anyone has any clue?
Hi,
I'd suggest formatting your memory card, then re-partitioning/re-doing whatever you've done to it.
Sent from my very dumb HTC Wildfire S (Stock Euro 2.3.5)
Did that a couple of times already
Well then I really don't know, sorry ...

Try using an SD Card reader and check its speed on your PC so that you know whether it's the card or the phone.
Then try a fresh ROM without Data2SD and check the speed.
Do each of the tests more than once cause sometimes there can be anomalies.
Same problem here
Bout a Samsung class 10 ,16gb sdhc and transfered some files to test the speed on my computer
I got 21mb write and 24mb read speed just as it said on the box
made partitions with Minitool to creat ext4 at a 32 cluster size
next thing you know even in windows my speed went down to 1mb/ and 2mb/sec
Anyone know whats going on here ?

There are several factors that could play into it here.
How are you accessing the microSDHC? USB cable to phone / plugged with card reader?
Can you test with a more reliable tool, like CrystalDiskMark?
Windows may be buffering the transfer and giving wrong numbers.
It could be that Minitool did not align the partition(s) properly, as it would have done for built-in SSDs.
Did you shrink the (first) FAT32 partition and create the ext4 at 'the end' of the available space?
On my WFS + SanDisk 16GB, Class 10, I created the partitions with CWM, and DATA2SD (Data2sdV2withA2sdremover_by_jikantaru) had to recreate the ext3 partition, because it was improperly aligned. This is from the data2whateverlog.txt:

I checked the speed with RoboCopy over USB to the WFS, it was about 4MB/s.
CrystalDiskMark reports 4.5MB/s write speed over the same connection (with 5 runs of 100MB data).
Try using SD-Booster app
You're right litemaster ! my windows was showing the wrong figures while transferring files .
i tried the sd tester and booster ,speed results weren't all that bad , 10mb read /10mb write.
and in windows it shows 2mb but file transfers at a much higher rate some times 30mb/sec.
Appreciate your your help buddy and Eduardo
P.S... By the way , given the results , this samsung class 10 isnn't that bad. Bought it for £12.00 from amazon.

Probably, you'll have to generate a valid pit file.

There's no exact procedure. The best way is to check under /dev/block of there is any block device listed. You can use adb shell to list all mount points and see if something coherent comes out.

I'm sorry again for this second noob question but how do you check "under /dev/block".. or "adb shell" Is it by using the command prompt or cygwin terminal? really confused with all these stuffs. sorry :/ just new to this.

You need to have adb installed on the computer and then enable USB debugging on the phone, and connect it via USB to the computer. That's basic stuff you should learn first.
The other are basic unix commands.

Do you have any idea where are the photos saved by default in the Galaxy S3 (i9300)?

Thanks a lot.
So I mount the partition and I'm able to see a lot of files but none of them are photos taken with the camera.
As soon as I noticed that the photos were gone I rooted the phone, installed CM10.1, then installed CM9, then I started to pull out the partitions,I know this may affect the data and some photos may not be recovered, but I was hoping to recover at least some of them.
--My mmcblkop12 partition (userdata) is about 11.5gb, is it possible that I did something wrong when pulling the .raw of the partition file out of the phone?
Should I pull out the raw file again from the phone?
Should I try another recovery software?
Thanks in advance

On Nexus devices the internal sdcard is just a folder inside userdata, so if you formatted userdata is probably that they got affected.

Hi,
I tried this command but get an error. "Permission denied"
I have SU & busybox installed. Running PSX custom rom.
How can I fix it.
Hi guys !
I've made some research about the partition sheme of the GT-I9195 and here's what I found :

What's interesting is the size of /system : 1500Mo !!! That's really big when you know that CM11+Gapps take approximatively 500Mo of /system space. There also some other parition un-used for custom rom's users (/hidden which contains sammy dummy file or /fota which is for over the air update for official rom). So don't you think there should be a way to delete some partition so that we can gain in space for /userdata ? I'm asking because i know it was possible for my old phone (Galaxy ace 2) and I think it would be pretty nice to gain 1Gb of space for daily usage.
I do not think it is possible to repartition s4 mini's flash storage.
You said it was possible on your old ace 2. I say it was also possible on my old galaxy s advance
That is because those devices had seperate partitions for system , internal storage , data (where u install apps) , cache and a special partition called 'preload'.
If I can remember correctly the hidden.img files from firmware reside on that preload partition. As you can see , with use of a "pit" file we can repartition internal storage, system and data such that we can either have more room to install apps or more room for storage.
But such a work is not possible on s4 mini. Because the internal storage and data are on same partition. /data is where u install apps .... /data/media/emulated/0 is your internal storage. This means data and storage share a single partition.
Yes i've also noticed what you just said. In previous samsung phone, there were two separate partition for user. One purely for storage (/ums or /sdcard0 if I remember correctly) and another one for the apps or the user's setting (/data). Now those two partitions have been merged in galaxy S4 mini, which is a big improvement.
But what I want here is to resize /system partition which is really too big for custom roms so that we can use that extra space for /userdata. In fact, i'm pretty sur that CM11 with a small Gapps package could fit in 500mo and that's all what we need because /system is in read only isn't it ?
And by the way, /system and /userdata are correctly two separate partitions.
You can go the other way.... Integrate apps in system.
I think this is safest than repartition
I've read a number of forum posts about how to unbrick a hardbricked galaxy S3 and followed them all and even tried countless times the same method as is suggested, yet I can't get my phone to boot at all. Anyone out there have any advice? I rooted my phone just fine and then flashed Android_Revolution_HD-SGS3_53.0.zip onto it through clockwork mod. Everything appeared to be installing fine and when it came time to reboot, clockwork mod notified me that something appeared wrong in my boot file and I may lose root priveledges. It then asked if I wanted clockwork mod to fix it and I unfortunately said yes. The screen immediately went pitch black and nothing I have tried gets it to show any signs of life.
I have a 64 GB micro SD that I've used with the command
Code:
sudo dd if=Desktop/debrick_sph_l710.img of=/dev/mmcblk0
I then check it with
Code:
sudo fdisk -l /dev/mmcblk0
and get
Code:

The backup GPT table is corrupt, but the primary appears OK, so that will be used.

The phone acts no differently with the flashed sd card than it does without it. Is the only way to fix it with a JTAG?
U need 16gb sd card, debrick image for your phone. Then you can boot into download mode and flash in odin! Get a high quality 16gb card

I'm using a 32 GB SanDisk micro sd, could it just be that all the debrick images I've used are just the wrong ones?
Its possible but i think if your phone is 16gb than you need 16gb sd
