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

Formatted SD to NTFS, any way to get it back?

Hi everybody,
I have a huge problem (for me anyway) and I can't find a solutions (i've searched for 2 hours now!). I hope somebody can help me.
I have a Sony Ericsson Xperia Arc S rooted. Basicly I wanted to transfer a big file on my SD Card. Without thinking i converted my Fat32 SD Card to NTFS with the command prompt in Windows XP. After converting I could still see all my files etc on my laptop.
When I disconnected the phone from my laptop, the phone couldn't recognize my SD card anymore and offers me to format it! So I figured I'd change it back, but I'm not able to connect the phone to my laptop trough USB, it just doesn't offer me the option.
When I insert the SD Card trough a MicroSD adaptor in my laptop, Windows won't recognize the disk either, and offers me to format it to a 512 byte disk - the SD Card is 16 GB.
I'm really freaking out now since there is alot of important documents and photos on the SD Card. Is there any way to force connect the SD Card trough the phone with the USB Cable? Since the files were available before disconnecting, i'm sure they're still there.
I tried 2 partition recovery programs (testdisk and File Scavenger) but they either recognize the Card as empty 512 or 1024 byte.
Is there any way I can format the SD Card back to Fat32 trough USB, or just even recover the files on it?
I hope my stupidity can be solved painless
Thanks in advance...

Didn't you make a back up of your files when you converted it to ntfs? Doesn't Windows normally format the card when you change its file system?

I have a feeling the SD card might've gotten partitioned... ie. you have two partitions on there now instead of just one. Open a command line with the with SD card connected to the computer, do this:
diskpart
list disk
select disk #(get the disk # from "list disk")
clean
That should get you back to a single-partition sd card.

Does windows give you any clues in the disk management section?
Right click > My computer > Manage > Disk Management

Download minitool partition wizard and then plug in your sd card and open the program. Then delete every single partition you see (ON THE SD AND NOT YOUR HARD DRIVES) and then click create a new partition and then format it to FAT32 and you are good to go !

Had the same problem with a flash drive
right click on drive > properties > readyboost > uncheck the box. Try to format the drive again.

Oh boy... The convert Fat32 to NTFS cannot be undone.
The tool was included with Windows XP for those Upgrading from Windows 98, who would still be runing FAT32 on their hard drives. It allowed them to upgrade to NTFS without loosing any data...
Unfortunately, the only way to get the card back is to Reformat it. I'd recommend the Command Prompt, and the Command would look like this...
Code:
Format /FS:FAT32 /X (drive letter):
The /FS switch tells Format.exe to format the specified drive in a specific file system. In this case, we're forcing it to setup a FAT32 partition on the disk.
The /X switch tells it to dismount the drive before formatting. This makes sure that nothing else is currently using the drive, so that nothing else can mess with the drive while Format is working with it.
After the drive is formatted, go download some decent data recovery software (I've always had good luck with iolo Search and Recover, but your mileage may vary) and have it scan the drive to recover your media.
Also... DO NOT MODIFY THE DRIVE IN ANY OTHER WAY! IF YOU WRITE ANYTHING TO THE DRIVE, COPY FILES TO IT, CREATE FILES ON IT, SAVE THINGS TO IT, YOU WILL LOOSE ANY DATA YOU PREVIOUSLY HAD ON THE DRIVE! Naturally, formatting the drive has a chance of doing this anyway, however, the automatically detected sector size should match the original sector size, so the chances of loosing everything are slim to nil. All hell breaks loose when you start adding and removing things from the drive...

Emulation of SD Card

Is or has anyone thought of or tried this?
What I would like to do is use a terminal of sort to run an emulator on my phone to run grub4dos off my phones SD card.
sent to you from my PoS

I'm confused on what you mean... our internal storage already mimics an SD card

So a home PC can run through "virtual memory" an environment where one can test USB Boot Devices. Qumeu is the program I am currently using to check my USB Flash drives with "ISO" files.
Essentially I run Qumeu and then I can see in a GUI my USB device and work with it.
sent to you from my PoS

What i have going is as such:
2 partitions on my SD-Card. First partition is for my phones pictures, apps and roms ect... Second partition has my ComputerToolbox on it. Grub4DOS is the bootloader along with the ISO's i am currently using for troubleshooting a computer.
What I am currently doing is "removing my MicroSD Card" and then put it into a "Standard SD Card". I then place that Standerd sdcard into the computer which I would be fixing and run things as if I were using a USB for preboot repair/recovery.
What i find interesting is for Android Devices I have to remove the SD Card.
For my IPhone one can just plug the phone in through a USB and not have the issue of the computer "Read" the device as a usb device.
Any and all help is very welcome... Thankyou.

Wait what? Xperia S doesn't have a memory card slot. If you're referring to USB, how did you connect it to a cell phone?

No what i meant was that maybe xperia s doesn't read NTFS file system that's why it's not detecting it. I never tried such thing so i can't help you much other than that. Is 32GB not enough for you lol?

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.

Anything but the applications installed themselves. You can store whatever you want on your SD, no limits, just no APPS2SD yet.

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.

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.
