USB Mass storage mode - can't see drive in Windows.

Hi, I'm having trouble when using USB mass storage mode on my Kaiser TyTN II with Android Froyo.
When I connect the phone can't see the SD contents from the FAT32 partition.
I have flashed on my TyTN II the latest 2.6.32 kernel from here, and i'm using the Incubus26Jc's Super FroYo RLS16. I have partitioned my 4gb SDHC using GParted to 3 partitions, one of ~3gb in FAT32, next to one in ext2 of ~64mb, and the last one in ext2, of ~1gb for the system.
Strangely enough when using Ubuntu Linux, it sees ands mounts all three partitions without problems. And when inserting my SD to a card reader on windows, it sees the FAT32 partition and I can browse it, but I want to do this with the card on my phone and on windows.
What can be wrong?

You can't do nothing, actually Adb driver for our kaiser is not working on windows...

I'm testing now on my Windows XP laptop and it works... strange.
My home computer is running Windows 7 (and ubuntu) can't it be a problem of w7?

Oo are you serious?

ADB was fixed in the latest version of l1q1d's kernel, but is still incompatible with Windows 7. At least, in my case it doesn't work in Windows 7, causes my computer to freeze until I pull the plug on the phone.

2.6.25 kernel has nice compatibility for Dual Mount SD Widget, check if Super Froyo supports .25 kernels. For me Not So Super Froyo is doing the job on .25 kernel. Default USB Mass Storage mode never works. You can use Dual Mount SD Widget to do the job
For adb, I had no problem with it on .32 while I am using XP.
HUGE EDIT:
Now I understand
Windows can ONLY ONLY see the 1st primary partition on your Removable Flash drive. Plus, linux FS are not recognizable for windows. (you can use Partition Magic or a linux FS supported partition software to actually view them that they exist).
If you want to partition your SD Card in windows, just install HITACHI Microdrive Driver for your SD Card's removable storage and it will identify as a removable hard disk. (I actually did that to have 3 partitions on my 16GB Data Traveler )

Well I already knew that, but I want to see at least the FAT32 partition for application install, loading mp3, and occasional data storage.
I'm only a couple of days in the android on kaiser world, what is ADB? I read that you need some drivers to make it work, and can be used to install apps etc. but when I connect the phone it doesn't request me drivers unless I select mass storage mode. On Windows 7 it sees it as a Disk in device manager but can't see the drives. On XP it has no problems, it can browse FAT32 part.
So if Android is exposing the phone as a mass storage drive why it doesn't work in 7?

Because android's itself "Turn on USB Mass Storage" mode doesnt work. Use a Multi Mount SD Widget or Dual Mount SD Widget or SD-Share to do the job
ADB is: http://developer.android.com/guide/developing/tools/adb.html
Just a tool to remotely administer your android device from command prompt
Try installing Hitachi Microdrive Driver in Windows 7 and see if it does any better

Thanks for the tips. Are you suggesting that installing the Hitachi Microdrive Driver (by the way, I noticed that it's intended for Windows XP) could help in mounting the device using Android's built-in mount option?

Hitachi microdrive driver is intended to identify your Flash Drive as USB Hard Drive to see all partitions correctly in windows and allows you to partition your USB flash drive
Nope it wont help, since .32 kernel has not supported USB driver which hinders the USB Mass storage functionality, even through Dual mount apps.
If you are using Kyle's FAT Free Froyo or Not So Super Froyo, install a .25 kernel and then use Dual Mount USB app. It will work for sure.
Another Work Around:
If you just want to move some files to SD Card and you connect your network connection through wifi, you can try ES File Explorer to view Windows Based File Shares, just like you are seeing shared folders from another PC I use it since I connect my mobile and my PC through a wifi router

What filesystem should I format my 32GB microsd card to?

So I got a great deal on a class 10 32GB Samsung card, it came pre-formatted to fat32, however I had the wild idea that android supported NTFS based on something I read in the past so I formatted it to NTFS on a windows system and copied some files over (some being over 5GB each)...plugged in my card and turned on my phone and I get a message saying my card is blank or the wrong file format...guess it doesn't support NTFS
I know if I use the phones built in format utility it will format to fat32 which I don't really want because of the filesize limitation, I'd like to be able to copy 8-10GB files every so often so I can use my phone as a little shuttle drive in between places...
But I also want the ability for windows to be able to read my sd card if I change my phone into USB mode so I think that excludes the ext3, ext4 format which I think android will read...
Any ideas?

if you use windows, fat32 is the way to go so then you can connect the phone to computer and still can access the files

The reason the op doesn't want fat32 is because he has single files that exceeds 4 GB that he wants to transfer, so fat32 would not work for him.

Windows also recognized NTFS by the way.

format it ext3/4 and then install an ftp server app on your phone.

There is an app that works fine
I have exactly the same problem. I want to have the sdcard in NTFS so then I do not have the 4GB limitation of FAT32. The is possible to have .mkv files on your phone or tablet.
In the case of my table the N8010, I have formatted the sd card on Windows with NTFS. Then installed the "paragon" app from market which works very good. It recognized the sd card in NTFS and mount perfectly. But it seems that when your card is overloaded with thounsands of files and some big 6GB file, then comes the problem. Android JB everytime that comes out of sleep, it will check for errors the sd card. Everytime! Then, I get the message "sd card checking for errors" and never gets back. The sd card is not recognized anymore until I reboot the device.
I think that the paragon app is not perfect and might have bugs, but
Is there any way to disable the "sd card check for error" functionality? Have read some threads about it, to delete some file from system, but that method produces inconsistencies with other apps.
By the way, I have tried to format on ExFat, and had the same problem. When the card is almost full it will never end up checking for errors. I finally broke the sd card when I formated it with ExFat and 64k allocation size. It was not regoznized neither by windows and android afterwards
thanks

I don't think you broke it unless you fried the flash chips. You can try using the disk manager in windows and try to see if it sees it. Or just learn how to use Linux command line tools and fix it that way. I recovered 80% of my pictures off of a dead SD card using dd and a file recovery utility. I don't recall which one. That 16GB SD card now works just fine as a 12GB card. I don't trust it for any more than shuttling between systems though.
Also, I've never had good luck with exFAT. I much prefer the EXT filesystems, but they aren't natively supported in windows or most cameras. Maybe try NTFS without journaling (If that's even possible)

exfat is proprietary windows and needs licenses. android won't support it.
ntfs is a journaling file system and will impact performance if you can get android to read it.
ext2/3 is the best solution. there are utilities you can install so windows can read it.

[Q] Which kernel/ROMS support > 4GB camera files

I am trying to find the right ROM which would let me take > 33 min videos with the camera. I am trying Chemistry ROM now (LJ7, android 4.1.1).. while it is working with my exFAT formatted SD card, the camera stops @ 4.2GB file size.
Any suggestions would be GREATLY appreciated for a webcast I'm doing soon.

In case anyone falls upon this same problem, I found a better solution. Instead of using exFAT, use NTFS. It is better supported on all platforms. Simply format the card with NTFS on any modern Windows machine. Then search and install Paragon NTFS on Google Play. It will simply work.

I was about to suggest that it probably has to do with your card being formatted to some sort of FAT filesystem....but anyway, nice :good:

Remove the card and plug it into the converter and plug that into your computer or card
reader then re-format using FAT32 ONLY then put it back in your phone and then your 64gb
sdcard shall work!

Use the Windows drive manager to delete the partition on the MicroSD, do not reformat it with windows, plug it into the phone, and attempt to mount, it should do so but with 0 space now. Format it with the phone. Or look for the tool "fat32format" on the internet (Google is your friend) in order to force a format in FAT32.

Then try exFAT but if you have a windows computer, the default is FAT32.
If that don't work you will need to find a friend or relative who has
a windows computer which you can use to format the card using FAT32.

nope, you cannot install apps on external sd on the s4 yet.
even the apps2sd is not compatible with the S4.

You can have all your mp3's, videos, movies, pictures and documents plus backups of the rom and new roms or other
stuff but you just cannot use it to install apps until one of the devs finds a way to create a compatible app which will allow
for app installation on external sd.
Something similar to the apps2sd app which is not compatible with the S4.
Perhaps the developer of that app will upgrade it making it compatible with our phones.

This isn't actually true after a certain version of windows i think since vista(May be wrong) exFat is the only option you get.

Google it and look it up,
Ever since windows xp fat32 was always the default when formatting usb flash drives(memory sticks) and sdcards.
Right now I am running windows 8 but I ran all the other prior versions of windows including windows xp.
When formatting hard drives, even external usb hard drives then windows (all versions) default to NTFS.
I never seen any versions of windows operating systems defaulting to exFAT.

Your right actually I got confused its actually partition space anything over 32Gb is out of a normal fat range for windows.

1) Make a LiveUSB stick of Ubuntu.
2) Boot into the USB stick.
3) Use GParted to format to Fat32.

Or you could search for 1 of the thousand formatting utilities that will do it and not have to download a 2gb file.

Do you know if due to the size of the memory card the phone takes a lot more time to load stuff??? I do not want to buy a 64gb if it will slow my phone a lot. If that's the case i may have to buy a 32gb card. Please tell me your input on this.

Well not in that sense but let's say if you would like to play a video or a song you have saved in your 64GB card. Does it still play it right away or have you experienced any slow downs? Someone who i know that works closely with phones informed me that it slows down the phone when loading files such as mp3 files or video files. Thanks dude.

[Q] MicroSD formating FAT32,NTFS?

I can not transfer larger flies on my microsd via usb cable,for example some HD videos,the only way to put that on microsd,is to unmount card put in microsd adapter format NTFS in windows and then tranfer large file,but when i put back sd in my phone i cannot use it until i do formatting again ,so i suppose that phone format card fat32 so i am not able again to transfer large files...Any suggestion? Does ARHD sense rom support that format?

You're quite welcome. FAT32 was the old reliable standard for so long. But as you know, it doesn't support file sizes over 4 GB (along with some other limitations). Now different devices use different formats, and there seems to be no "go to" format. Windows seems to default to NTFS, exFAT seems to play better on Android phones (at least HTC), etc. At least from what I can gather by searching online, there don't seem to be any easy "silver bullet" answers on what format to use when. So your confusion is quite understandable.
