Never any LOST.DIR folders on exFAT.

[Galaxy S II Android Development] pSyCh¤_O_O:
I've been on RC1 since released and its spotless on SpiritRom...

I call this "more than stable"

What's all this reformating partitions? Any benefit ?

Recommendation's?

TIA guys.. Sorry for lazziness [emoji28] I read everything but sometimes info goes through me instead of in my head...

and I'm a noob with FS's
[Galaxy S II Android Development] cybernetus:
Mate without a logcat we isn't have data to work.

For this I need to install a rom to work on this problem but I will not have time to do this.

But, try this.

Change your io to sio/noop and change the in kbytes to 256 or 512

On memory change the sleep me to default

Test and post your results

I think this thread

http://xdaforums.com/galaxy-s2/development-derivatives/rom-brickbug-aftermath-speeding-t2843238

has some good points, regarding trim and brickbug!

I just gave it a try with a emmc VYL00M fwrev 0x19 and it worked.

Some sort of speedup while switching between apps.

It could be a great feature for dorimanx test kernel.

[MENTION=4663860]Computoncio[/MENTION] (where are you man??? ), [MENTION=1670821]cybernetus[/MENTION] i've been discussing over pm with one of members and we really need dorimanx boot logo back again to be able to select in which rom to boot on startup....not Stweaks after 1st rom already boots....do you have any idea if/when it's gonna come back?....It's breaking famous dualboot imho and that's not how it's supposed to be....:)

How can you trim and also keep using this kernel?

you cant, you can switch the kernel, trim and then go back to dori.

Ok guys, I am on 10.44 RC2 now and it seems that it brought a big effort to format internal and external SD to exFAT like [MENTION=5644065]Spaulding89[/MENTION] suggested :good:

No more system freezing until now when opening a folder with many pictures or apk's in it, the thumbnails load now but very slowly.

Also the data transfer from internal to external or from PC to internal/external SD takes a lot of time and is aborted some time :confused:

So what could I do to speed things up? I am using ondemand/noop right now and for formatting internal and external SD I chose standard values of the size of allocation unit (I think it is now 32 kilobytes external -> have a 32GB SD Card and 32 kilobytes internal SD -> could this be to small?)

[MENTION=1670821]cybernetus[/MENTION]

you wrote:

Change your io to sio/noop and change the in kbytes to 256 or 512

I think ondemand/noop is also a good combination!?

And what do you mean by 256 or 512? In STweaks for internal memory?

on memory tab I have both set to default like [MENTION=3763274]rkoby13[/MENTION] in his profile.

And what about STweak settings? I am using the profile of [MENTION=3763274]rkoby13[/MENTION] at the moment but for me, the battery drain is too high because these settings are too aggressive for me. Don't get it wrong but I am no gamer so I don't need 440 MHz GPU speed or 1300 MHz CPU ;) I need a good balance between stability and battery lifetime. I am on CPU group 2 only.

So any help would be appreciated, maybe [MENTION=5644065]Spaulding89[/MENTION] you can send me your profile on AH because you are also on exFAT at the moment ;)

[MENTION=5074262]StanTRC[/MENTION]

Any plans for updating CWM recovery? I think 6.0.5.1 is the most up to date :good:

[MENTION=4546441]Twiq[/MENTION]

The only "problem" of exFAT is, that cleaning partitions does not work anymore.. (screenshot). Is this a problem and is there a workaround?

Regards
[Galaxy S II Android Development] m1trand1r:
Mate i'll revise my profile and I will lower aggressiveness of it....then i'll post it again as separate "battery friendly profile" :p...

As per your slowdowns that you mentioned so many times by now....I dunno...maybe you should just go in with fat32 for both sdcards with 64kb cluster size....or would that be too small if you have some big files on extsdcard ? [MENTION=4546441]Twiq[/MENTION] said that 64kb cluster size works well with small files...;)
[Galaxy S II Android Development] j1gga84:
[MENTION=3763274]rkoby13[/MENTION]

many thanks! ;)

Hmm, good question if 64kb is too small.. I have big files and also small files on external SD but when I transfer files between external SD and PC they normally are big, if you see them as a whole..

Hey....just testing my revised profile...1.2ghz clock....lowered GPU settings....you want it

[Galaxy S II Android Development] Twiq:
He might mean storage read ahead value, stock settings for 16gb is 1024

To check exFAT FS volumes you need to use fsck.exfat and not fsck_msdos, but note that it can't repair lost clusters as most of rom/kernel sources clearly says that repairing is not supported (i'm not too sure about this since it's not well documented across rom/kernel sources).

And that's the reason why i'm looking for another alternative to exfat, which is FAT32 with 64KB cluster size. The only significant differences between those two is the date/time extraction from files, on FAT32 took almost 2 secs, and on exfat it took 10ms (referenced, but forgot the link).
[Galaxy S II Android Development] Saber:
Well the only thing we can trim is the partitions on your phone. The benefit with trim is that it keeps your device faster for longer and you will see fast write speeds (I might be wrong, but I've seen some benchmarks).
[Galaxy S II Android Development] Twiq:
Too bad it will be hard to be implemented to dorimanx, since the kernel uses VERY different sources

ow and during 1.5h uptime...I didn't kill a single task/app so OOM seems to be ok....my guess is that something on v21 doesn't fit for Android 4.3.....because v17 was the last running excellent on 4.3....others don't.....anyone on Android 4.3 here?....some feedback would be appreciated from 4.3:)

Agree, with you statement, been following dorimanx kernel since 9.14 with all kind of roms.

-have some issues with slimbean 4.3, but everyone seems to have them on every rom based on 4.3.

im just a noob on this according too me, but always try first 3 hours with test of all apps and deep sleep at least 7 hours. used too give a nice point there the damage are, or if there are some problem. :P

Please.. Please read before blindly flashing something that already broken.. If you are not ready to lose the responsibility of have a dead device or whatsoever.. Don't take the dive here.. We are taking the risk to test the greatest and best kernel for sgs2.. So that others could have a stable and problem free kernel releases..

Anyway.. Flash 9.34 tar or philz kernel will get your beloved device back.. After flashing, go right back to recovery and flashed whatever that's had no known issues..

it actually shouldnt, as far as i read it is included in every kernel but disabled (correct me if i'm wrong)
[Galaxy S II Android Development] j1gga84:
Thanks, I will try to format to FAT32 now with 64KB cluster size :good:

Sometimes exFAT gives me also problems when I am trying to copy files to external SD. It does not work every time..

It is ok to do a fast format only or is it necessary to do it slowly?

And concerning the storage read ahed value, what would you set in STweaks? I am using a 32 GB card.

Regards
[Galaxy S II Android Development] Twiq:
You're correct that it's disabled, i've read the how tos, but it requires the kernel dev to revert the brickbug, then apply specific codes to some other sources (i forgot which files), but this is the issue, while the trim enabled kernel uses samsung's sources, while we're using different sources, i'll prove my points later as i'm still at work :D

To be short, we need @dorimanx to help us overhaul this if we want to implement it. Thats why i said we're using VERY different kernel sources

edit : to be clarified, i may have looked into different sources.. apologies

edit2 : looks like i'm beginning to have dyslexia for today.. i can't read sources properly. maybe after a sleep :silly:
[Galaxy S II Android Development] stylemessiah:
Okay, its late and im bored/tipsy, but why always the questions about exotic filesystems when fat is the most reliable??

Thanks for explanation :good:

It works now and both drives should be FAT32 now as you can see in screenshots (internal only the UMS -> Media? Partition - correct?)

Now I also understand why this one tutorial recommends formatting drives to ext4 ;)

But in my opinion it is not that easy.. So I am going fine with FAT32.

In my opinion the data transfer rate between PC and Phone is slower than exFAT like [MENTION=5644065]Spaulding89[/MENTION] described but FAT32 is not as error-prone as exFAT so I can live with the slow transfer rate. If I have a lot of free time and if I am ready for a little risk I could also try to format to ext4, maybe this is faster but with ext4 we have the "problem" that mass storage mode is not working under windows, only MTP.

For me, FAT32 is running much smoother than exFAT on my device, very fast response and no errors compared to exFAT :good:

but what is this fdisk and gdisk for? I did not get it ;)
