UPDATED : Real fix for the "stalling/lagging" problem

[Guest mimocan]

Yea, i have root access from MCR r2, i did not reflash from the scratch though. I apply your fix directly.

0	   /disk/

# cp -rp /data/data /disk/

cp -rp /data/data /disk/

cp: can't create directory '/disk/data': Read-only file system

#

Does this have to do with the way i partition my drive? Maybe i should use gparted instead of paragon but the problem is i do not have a blank CD to boot up gparted :angry:

update 2 : i use gparted, splitted my partition into 300Mb (fat32) + 1.6gb (ext3) on a 2gb microsd card. Still having the same problem. Should i just reflash again everything from the scratch? hate to restore my apps/data from backup though :D

can you do this right after you do su:

su -

mount -o remount,rw /dev/block/mmcblk1p2 /disk

and then do the cp stuff

mount -o remount,rw /dev/block/mmcblk1p2 /disk

mount: mounting /dev/block/mmcblk1p2 on /disk failed: Invalid argument

however, i tried again with partial command without the /disk at the end and i get this :

# mount -o remount,rw /dev/block/mmcblk1p2

mount: can't find /dev/block/mmcblk1p2 in /proc/mounts

hmmm, something is missing? and just for extra info if it helps, this is what i get my typing mount only :

Also, just want to double check, during flashing with Odin, the checkbox "Auto-Reboot" and "F.Reset Time" is checked by default and i did not touch the setting at all. That should not be a problem right?

[Guest kanzlr]

same problem as gravityz3r0.

disk is partitioned as fat32 first, ext3 second.

when I type "mount" I don't see /disk mounted at all, btw.

when I just try to remount /disk by issuing "mount /disk" it says

"can't read /etc/fstab no such file of directory"

and doing a "more /proc/mounts" also doesn't show disk at all

it looks to me that the partitioning process is not sucessfull completed.

[Guest gravityz3r0]

it looks to me that the partitioning process is not sucessfull completed.

This is what i do in gparted.

1. delete all partition clean, such that it shows unlocated of a bout 1.9Gb

2. Create 1 pending FAT32 partition of 300Mb.

3. Create pending Ext3 partition of remaining size (about 1.6+gb)

4. Apply

5. Format FAT32 (pending)

6. Format Ext3 (pending)

7. Apply

Reboot.

mimocan if you dont mind can you let me know your msn or something so we can discuss and probably sort this out quicker? thanks!!

Edited July 14, 2010 by gravityz3r0

[Guest kanzlr]

hm, when I insert the SD in my PC, partitio manager shows it as two partitions, first fat32 with 996MB and the rest in ext3...?

so you mean I should repartition the disk again?

Right update to my post yesterday with benchmark results.

Reflashed my phone so i don't have JIT on it this time: (Got a Sandisk 8GB Class 2 card in the phone, Getting a Class 4 tomorrow or so and ill post the new results then)

Added two graphs of the phone before and after fix applied. Can't show one with JIT as that crashes the app.

I had similar problems with "no /disk". The main reason - wrong preparation of SD card.

Success steps:

- you need a card reader

- create partitions both as primary

- format partitions! At least ext3 partition, cause fat32 may be formatted from the phone

I have created and formatted partitions as described above by Paragon HDM, and it's worked for me. In case of problem with mounting fat32 partition to windows - just format it by the phone, it will not erase ext3.

[Guest crabby09]

Holy crap!

So this fix does wonders to the phone?

Can anyone explain in real terms what this does... I'll give it a go tonight, but am really interested why this helps so much.

I do not have a card reader, can i just leave it in the phone as the card reader?

Paragon gave me problem since it could not partition the sd card because it interprets it as a removable drive. Windows does not allow partitioning of removable drive. So i had to do it on gparted.

no, doesn't work

[Guest gravityz3r0]

no, doesn't work

Is there a reason for it?

[Guest psychedelic'd]

Just buy a USB card reader. They're quite cheap.

I'm still wondering if this process can be reverse. Any one know?

[Guest kanzlr]

I created two partitions in Paragon, formatted both, still no /disk mounted

Is there a way to explicitely tell him to make them primary partitions?

thats how it looks now:

Yes they are right. Use card reader, i happened to find a micro sd -> SD converter. plug it in, repeat the partitioning and now it worked!

For some reason, you can't do it with the card in phone, even though everything seems normal.

[Guest HansBaer2000]

Found a sollution for the mounting problem, now windows finds the drive

open disk management (a windows programm, just type it into the start bar)

right click on the fat32 drive

change drive letter and choose one

now it should work fine!

Edited July 14, 2010 by HansBaer2000

[Guest kanzlr]

I already use a card reader :/

tried partitioning with PC with Paragon, also tried it with Mac Disk utility and formatted it ext3 with paragon...hm.

maybe the ext3 formatting in Paragon doesn't work, because I format both partitions, also the fat32 one. But when I insert it in the phone, it wants to format it again, because it says it doesn't recognize it

Odd, i've been struggling over and over, and it was solved the moment i switch it to a card reader. I'm using gparted by the way.

Yes, it's shown as formatted in Paragon for me too, but upon plugging it in windows, it says that the card cannot be recognized and needed another format :S

my quadrant now shows 1364, increased from 836 :angry:

thanks guys!

Edited July 14, 2010 by gravityz3r0

[Guest kanzlr]

ok, there is definitely something wrong with partitioning.

windows disk manager shows that there is just one, big 1,85 GB GPT protected partition on the drive...weird.

have to explore this in the evening :angry:

format the external sd card in the phone menu first

@mimocan are the fixes in I9000XWJG5 kernel related?!

Changelog:

- improved energy management in suspend mode

- updated YouTube, Google Maps

- Change Low-memory Killer Thread

- many minor fixes

if so is it then still good t use your kernel?!

no it's still based on 2.6.29, so you are safe to apply my fix.

[Guest mimocan]

It's even faster when using ext4.

check the screenshot. I will publish the kernel with ext4 support anytime soon.

WOW! Did you think about making ext* partition at the end of the internal SD card? Is it possible?

still thinking about it but hard to create the partition with the internal drives.
