SD card speed fix - should work on any firmware [i have JG5]

[lenrek]

hi,

now another problem after typing...

busybox cp -rp /data/data /disk/

i get read-only file system??

anyone know the problem i have??

Did you create the 2nd partition > 2gb? If you did, please make it smaller than 2gb. From what I had read, that is causing problem.

Do a mount command to confirm your 2nd SD card is properly mounted. If it didn't get automount, then something maybe wrong with the 2nd partition. You may need to format again.

EDIT: From what I read, it seems, > 1gb for 2nd partition would be a waste of space. I only set as 1gb.

I think I will try this myself. But I'm just worried it will become an issue in the future with upgrades and I can remove the SD unless I power off the whole phone.

as i've understood it, with new firmware installs it should simply be a matter of reapplying the kernel. re the SD, u will need to switch off phone first, otherwise you will get lots of FCs.

a work-around for this is to type the following first:

busybox mount /dev/block/mmcblk1p2 /disk

I did everything step by step, i don't really see any performance difference what so ever in the Quadrant Standart (932) still far away from your result, could you tell me what i am possibly doing wrong ?

[aciduzzo]

what type of SD card are u using?
what firmware?
did you partition ext4 with v4 kernel?

[lolczester]

i formated my (kingstone 8gb) to 2 partitions, 1GB ext4 (which windows doesn't see) i have no idea how to check if it works

Firmware I9000XXJF5 (2.1-update 1)

well firstly you wouldn't get more than about 800-850 without the SD card fix, so it's almost certainly working. did you do a test before the fix?
which speed class is your SD card?
you may want to try flashing to JG5 and then reapply fix. I'm on JG5. i tested earlier and i got 1688. my SD card is a class 6, but that shouldn't make too much difference.

Can you guide my how to check the class of an SD CARD ?
I understand that it maybe speeded up my phone, but the difference is way to big 932 and 1688, something is wrong in that case.

It should say on the card. personally, i would flash jg5 and then reapply speed fix.
