hi guys i'm trying to find a solution for sd cards unmount on lg optimus one!!!i have a kingston 8gb cl4 and i had a 4-5 remount a day before trying this:
format with windows,choose file system fat32 and in allocation unit size choose 64 kb(should be the maximum) and give a name!
after this i had no problem for 5 days: no remount no reboot!!!
i would share this because it could be a solution....so anyone have problem may can test it!!!
there is a solid solution. buy a class 4+ micro sd..
but, kudos to you! i have a class 4+ micro sd so i can't test it out, but i'm sure others will.
btw this will kill all ur data in sdcard. backup is needed

So easy if it isn't your money that will be spent
BTW, I have a class 4 SD and it unmounts regulary, so class 4 doesn't really work.
Thanks for the tip dongimin2, I'll try it out.
before i bought kingston class 4 i had the original microsd that was shipped with optimus one and i never had problems!the problems started when i bought kingston memory!....howewer.....another day without a remount or reboot!
If speed is the problem (assuming it is), then I bet reiserfs solves the problem. That is if someone can get it to work with Android Just my opinion though.
EDIT: reiserfs for Android exists. Can someone port it for the O1? xD
8gb cl6 never once had unmount. Previously on original card, unmounts several times a day

with me happens the opposite...with original sd never had an unmount....with the cl4 8gb several!howewer i'm passed a week without unmounts!
And... what about having NO SD AT ALL? Is it possible? Does it still crash the phone?
Can someone test it (I don't own the device, sorry)?

Erm, this could really solve the unmount problem, I guess.
@kpbotbot reiserfs is goddamn fast..i have been it for past 5 years and not a single corrupt file ever..(MS needs to learn) having a2sd on reiserfs will be quite good and how abt using FAT and not FAT32 for saving data on SD..havent tried it but shudnt it work ??? Both fs have same 4GB filesize limits

But... Do android need an SD card (or an internal memory like the nexus S) to work properly? Or is it really possibile to boot without the SD

Have you tried using the old FAT on your SD? Afaik, max sizes for FAT is about 260~. I'm going to install either Debian Testing or aptosid tonight and I'm going to try out reiserfs
On the relevant side: I hope someone ports it on our kernel :/
I formatted the card from the phone , but nothing changed...i have root + milk os 1.0 touch lag kernel , before rooting + milk os kernel , i hadn't sd unmounts...i did a nandroid backup . Should i restore it ? , but i'll loose the overlock + no touch lag.. what should i do ?
Just an update: I formatted the SD card as the original poster suggested, and it did reduced the umounts considerably, but not totally.
I stigg get a umount every 5 days or so, which is surely better than twice a day
Looking forward to Gingerbread...

1- Format with windows mounted on USB from phone or use a card reader?
2- If i back everything up and after format put it back on will all my apps still work?

Hi, I recently bought a 32gb sdcard, but then i saw its FAT32 and
there is a size limitation of 4gb...
So i googled a bit, and i found out i can convert my sdcard to ext2,
How do I do it?

Question posted multiple times before a search of XDA may find the solution .
jje
I formated it with first software that came up after the google search,
but the galaxy s 2 says that the file system is not supported...
is there anything else i need to do to make it work?
Plesae help me i couldnt find anything!
I really need help here guys, I bought the sdcard
for putting hd films on it, and splitting them is not an option
because I use subtitles from a file and they are not together
with the mkv file...
It went to like page 5
What i think you need is link2sd from the market and dual partition the sdcard.

Which ROM are you in? Maybe you're ROM can't mount SD Card as ext2. You could also try exFAT.
I'm using Checkrom Revolution v4...
Using another program to format it will work?

You can create multiple partitions on your external SD card formatted with ext2/3/4 or NTFS (together with Siyah kernel and ntfs-3g) or FAT32. Use your PC and a partition manager or fdisk/mkfs on your rooted phone.
But you have to mount the partitions manually or you need special support from the kernel (via ueventd). If you want to replace the external FAT32 partition completely with another filesystem for use with the ROM as media partition you need a compatible mount manager (vold daemon). The vold version 2 in stock ROMs only supports FAT32. I guess there is no difference with Checkrom Revolution. As far as I know only CM 7 has support for a (read only) NTFS partition and extX.
Changing a kernel would make it work on CheckRom Revolution?
if so, is there any recomended kernel?
I am wondering the same thing. I am using the stock Samsung kernel...
Hey guys
I recently switched my 16gig SanDisk Class 4 card from my Atrix to the S3.
The problem I have is that in the storage settings I can't mount the card, the option is greyed out.
I have used an adaptor to check it works and can be formatted on my laptop and it works fine, it's just my phone doesn't seem to know I have it installed.
I've never had this issue before so all help will be appreciated.
Regards
Paul

Thanks for the link but I have a different issue to that guy.
My card isn't recognised by my phone or laptop when I plug my phone in.
If I put the SD card into a separate adaptor and plug into the laptop it sees it but it's just that my phone doesn't.

Get the latest 1.2.6 siyah kernel. I believe it includes the exfat stuff.
From change log
"fixed autoloading of exfat modules for cm9 (1.2.3 -> 1.2.4). you can use*vold-exfat.zip*(CWM flashable vold from samsung roms) to use exfat on cm9 (use at your own risk)"

Stock firmware plays nice with exFat, What I suggest doing is backing up the content to your PC.. then doing a format on your PC making sure exFat is selected.
The fix I had mentioned is for AOSP/CM9/AOKP roms which dont support exFat out of the box.. yet. The link which ciscostud had posted is that exact fix.
Im currently using foxhound with siyah, my 64gb card works perfectly fine.. in saying that I believe it worked with stock CF kernel also.
Perhaps by using it on your previous phone it had changed the microsd filesystem too some other than exFat.
You should be in the clear, Post back your results.
Thanks guys I'll give these solutions a try and let you know.

I tried flashing the kernel and the vold fix and the S3 still doesn't recognise the card even tho I've formatted it a few times.. It's definitely getting formatted on my laptop as exFat as well.
Paul
Does anyone still have a copy of the vold-exfat.zip file? I can't find it anywhere and I've been looking for the past 30 minutes too on Google, etc.... Thanks in advance!
Yes have been searching the net, and it seems the file has been removed off Siyah's site as well.
What happens to the crappy internal memory when you choose the data2sd option? Is it still accessible for storing files / movies / pictures etc. Or does the microsd card become the only storage option?
you will be able to access it under /data1/

It doesn't become data1, I made it become InternalSD.
There is a flashable file in post 2 of the androwook thread that will make that folder available from the sdcard.

And I also learned a lesson about not ejecting the microsd card while the system is running. Curiosity got the best of me.

i didnt know about that zipfile , sounds good to have it mounted on a better accessible place. maybe include that in the rom itself?

It really doesn't mate. I made the data2sd kernel and I should know what I named it lol
If it really did get renamed to data1 the script I also created in post 2 would not work

You know, that is the only option that I never tested. If that is showing data1 that is a very old one I made and should not have been included in 1.51. Wook must have added it by accident.
The script in post 2 to mount the folder into sdcard will definitely not work for you.
Any reason you're not using the clemsyns one with data2sd? Without that you are missing out on fsync, init.d and other speed improvements.

Yea it used to be like this in the old versions too.
I choose the stock kernel because of stability, have seen weird things happening with older custom kernels on this device, i think mostly due to overclocking and undervolting.
Is clemsyns kernel stable? No SOD, no instant reboots etc?

We all use Clems kernel. I use it now without data2sd but I also used it with data2sd for ages before while testing and I know 1 or 2 of the team members still do and we have never encountered any problems with it at all.
Sorry for doubting you earlier mate, glad you brought it up really so I will know to swap it out on the next release.
Weird how no one else has brought this up sooner but I guess everyone else who is using data2sd is using the clems version.

Does the clemsyn kernel make everything smooth even without data2sd? I was curious as to why you don't use data2sd still.

if you have never used data2sd with clemsyns kernel you will find the clemsyn kernel used with one of the two stock roms is the fastest your prime has ever been. with data2sd it is still slightly better. but not enough to warrant the purchase of an microsd card. In fact I will not even test non stock roms right now because this kernel is only available for stock roms and its way to big a performance hit to use another kernel.
noob question
hi this is my first post ever on xda, so i have some noob questions sorry, ive looked and havent been able to find anything concrete. i installed hairy bean 1.5 with clemsyn elite 1.7 kernel, but id like to try the clemsyn data2sd kernel instead because of the i/o issues, i havea 32gb class 10 micro sd, ive read that its a good idea to partition the majority of the card in etx4 is this true, im not sure how to properly partition for this rom, if someone could give me a recomendation that would be awesome, and from what ive understood so far if i install clemsyn data2sd kernel i would not have issues with accessing the internal storage of prime right?

You can use Gpart (linux) by running live cd or you can download minitool http://download.cnet.com/MiniTool-Partition-Wizard-Home-Edition/3000-2094_4-10962200.html you need a fat32 partiton first then the rest ext4. For the fat32 I suggest using a cluster size of 16k I have tried lower with poor results. Depending on what you plan on using the windows partition for will determine the size. You can go any where from 1 gb and up, just know that when you connect to the sdcard on a windows machine you will only se the fat32 part so if you plan on transfering files make the partition big enough to handle that.
And what is on the EXT4 partition ? System and other folders which is on internal storege??
thx

The only thing on the ext4 partition is the entire contents of /data
So basically the FAT32 partition is for media (music, picts and movies) and the EXT4 for the system to install app and what it needs to work? Is that right?

The fat partition is the External SD space. The ext partition becomes the entire /data folder from android which also includes the Internal SD.

Messing around with my new S4. For some reason I am already running out internal memory on the phone. Since I cant move any apps to the ext SD card yet..Im lost...never the less, I still bought a 64 gig class 10 card and put it in the phone. It won't read it. Just says Mount SD card. I try to do it and says the card is safe to remove.

The problem is in format of SDcard. Actually, Faux Kernel won't read exFat format, which is mostly used to format 64Gb storages. There two ways to fix it:
1. Flash Ktoonez kernel (KT-kernel) that supports exFat (just like stock kernel).
2. Find the way to format your SDcard into Fat32 format. There is utility named Fat32Format can be found on the Internet. Or, if you are on Mac - just select Fat format.
