[Q] SD Card Help! - HD2 Android Q&A, Help & Troubleshooting and Genera

Hey guys. I'm currently running this ROM, I've been using it for a few days and have had no problems but today, when I turned the phone off and turned it back on, it took ages to turn back on. Then when it did it all looked them same but was kept freezing etc., then up in the notification bar it said "SD Card Removed Unexpectedly" then my phone went crazy with FC's.
So I took out the battery and restarted the phone. Then, it would turn on and go to the lock screen but then it would reboot and be at a continuius* boot loop of the HTC 'Quietly Brilliant' screen.
So then I took out the battery again, this time I took out the SD card too and booted up and my phone was normal again. Obviously with no phone storage though as there was SD card in. Then after I just skipped the setup I put my SD card back in to my phone and went to the music player and all my saved songs on my SD card played. But no internal storage (I have the SD card partitioned with a 1GB Ext3 partition). Then with the SD card in knowing it still works I rebooted again, only to come back to the HTC screen again.
So basically, how can I fix this?
If I'm going to need to format my SD card is there a way I can backup what's in the Ext3 partition?
Thanks,
L.

Bump. Need to be able to use my phone properly again urgently. Thanks.

It sounds like something is really funky (faulty hardware?) with either your SD card or your phone. You could try reformatting it with that Panasonic tool...
You can backup your SD-EXT partition with CWM/CWR. You can boot CWM from MAGLDR without flashing anything. Just put zImage and initrd.gz from the CWM download on the root of your SD card and boot "AD SD" from MAGLDR.

Thanks for the reply. It's not the phone as I have a 2GB SD card in it right now but that's not big enough.
Yeah I have a problem with CWM, when I click AD SD it says some Kernel error thing.
Is there any other way to find the files in my Ext partition using my computer?

Unfortunately not that I am aware of. Where are the CWM files located on your SD card? Are they on the root or in a subfolder? Did you modify the path MAGLDR looks for the "AD SD" path? Are you using the latest CWM release?

Yep they're on the root of it. I think it's 1.12 I have ATM. How do I modify the path? :S

Nevermind. I tried re-installing and it worked on my 2GB SD. But the thing is, the files I want are on my 16GB that won't read lol. I'll try flash it on that now.

Tried to flash my 16GB. Says SD Kernel Open Failed in red letters? Works with my other SD card though? :S
Now I just tried with my 2GB and it's saying the same thing again.

[Q] MagLdr Android SD Card Problems

Hello guys.
I have a HTC HD2 running Windows Phone 7 (on MagLdr 1.2).
I want to DualBoot Android AND WPH. Ive watched a tut on YouTube: http://www.youtube.com/watch?v=JTHRAUHZHlo
I did exactly the same and after that i took this Android DesireHD Built: http://forum.xda-developers.com/showthread.php?t=881937
It worked fine but android said, that there isnt a sd card in the device. Of course it is, cuz android boots from the sd card. When i remove my sd card, android freezes (of course). I tried to restart and i put the 512 MB data.img in the folder but there was the same problem again..
I tried it with an other card and i pushed the button "mount sd card"
and than it said "u can take out the sd card now" (or something like that)
Plz help me!
I am having the exact same problem. Have you found the problem/solution to it.
thanks.
you both update you magldr that should fix your issues.
so get newest radio, than flsh magldr 1.3
before you update make a complete backup!!
hope you both have the right partition layout on sd card.
(first partition must be fat32 second ext3 or ext4)
hope this helps.
for tut look at forums or pm me!!
Can someone describe the exact steps that are required to mount the SD card when the Android build is being run off the SD card using MAGLDR.

They are running Android from their SD card. It is not going to show a SD card being in the device because Android thinks the SD card is the device......

This will not help them at all, MAGLDR just serves as the bootloader for Android not the OS.
Allso you can not remove your SD card will booted into Android if you are using a SD card build it is running of the SD card not NAND.

So basically I cannot mount the SD card, no matter how it is formatted ?
I totally have this same problem. Neither WP7 or Droid will read the 16 GB card I'm using to run Droid. I think I'm using the DesireHD build also, maybe its that? I can probably see if changing it makes a difference.
I have the same problem. First time i installed WP7 and android, everything was working fine. Then i had to reset WP7 because it kept freezing, i followed the same steps again to dual boot with android and it booted fine but SD CARD is not mounted for some reason. I have tried 3 different android builds with same problem. Any help or tutorials?

This happened to me too with two SD cards. What I did was I run the Partition SD Card from AD Recovery. I forgot the partition layout, just find something that works for you. I was surprised that it has successfully created a partition...this erased everything so I needed to re-copy ROM files to SD card via Card Reader on my PC.
When I did it over, It finally worked. Am now running Sensation XL ROM.

EDIT: even when i press mount usb storage under CWM i get the following error:
E: Unable to write to ums lunfile(no such file or directory)

Hi there...
I had this issue earlier this afternoon. What you can do it is format your SD Card via SDFormatter or format it using any digital camera.

Format your card with SD Formatter from SD Association - this helps; then copy your ROM-ZIP and then insert card in the phone and power it up to CWM.
Good luck

[Q] Access to bootable sd card from stock OS after 1.4.1 update

I have a nook color with dual boot from sd card. The sd card having an android 3.0 version.
After I got the 1.4.1 update, I noticed that I was able to access the sd card( the boot partition alone) from the stock OS boot of nook.
But now, dont know how, I dont see that anymore.
Was this a flawed update that was fixed or am I missing something.
Do help please.
I could really use the advantage of using the bootable sd card as a regular storage card when using the stock OS of nook. I prefer reading on the stock OS of nook.
Not sure why you're not seeing the SD card anymore, does it still boot?
SD card installs create multiple partitions on the SD card and the Nook will only be able to access the first one (boot). It should be accessible with any version of the Nook default OS.
You should have a media partition with a decent amount of room (1-5gb depending on NC version). That would give you more room than the 100-or-so mb on the boot partition.
Just found out that you can point the emmc install to see the "sdcard" partition of the sd card using the following info:

Yes, I can boot from it. Every time I plug in the SD card, the notification already says that it is safe to remove the SD card. In the device Info part of the setting, the "Unmount SD card" is already greyed, though it does say that the SD card is found.
It is however useful for me to know that the boot partition should always be accessible.
I did remove the SD card a couple of times without unmounting it first, could this possibly have corrupted the card?

Try to boot the uSD card (the one with Android 3.0 on it) and see what happens.
If it can, then it's good, if not, you can say it's corrupted.
Yes, I can boot from it. So I assume the card is OK
I plugged in other uSD cards and they get recognized fine. So I assume the Nook stock OS device recognition is OK.
I should probably recreate the boot partition as a last ditch effort
I had the same problem at first, but now I have mounted the correct sdcard partition that I wanted to mount.
I couldn't get it to work with editing the vold.fstab file at first. Then at some point after I manually mounted the correct partition through adb shell and edited the vold.fstab it now works.

problem with Recovery

Hi All, i have never had this problem before so i am at a loss.

I would try the latest Thor recovery and then a different SD.
Format it in android Phone .
This has happened in the past to many.. Just all of the sudden as you say. I believe the best result on solving this has been to format the SD Card with a Android cell phone OR by downloading sd format . utility and using that.. I ALWAYS Use my cell phone.. Honeycomb should have put a format utility in it.
Formatting a card in windows for android on some sd cards seem to cause trouble. as the card gets full. Android formatting seems to do something different then windows.Not sure what or why.
Good Luck

Can't Mount SD Card in CWM 5.x!

So i went to flash a ROM and now it says while flashing that the flash was aborted because the system can't mount the SD card. I'm using the newest CWM and have flashed stuff before. Not sure what to do, it wont let me make backups, restore, or flash anything.
I find it kinda strange, because once I reboot my tablet, everything's working fine, but it's not letting me install a custom rom
And yes, I have...
1. Unlocked by booloader.
2. Rooted my phone along with installing superuser.
3. Installed CWM recovery through fastboot (or whatever it's called, lol)
Has anyone gone through the same thing?
Bump....
Cm on guys I really need to get this rolling ...
What class SD Card are you using? I have issues with CWM on this Tablet reading anything above a class 6. I have a Class 10 SD Card that I have to swap Out and put in a different slower class card to flash roms and what not so I personally have had to deal with this because of the speed. Anyway hope that helps you out.
I'll try another sd card and see if it work out. Thanks for the advice!!
Bump. Using a different SD card didn't work, unfortunately

Back up all ur SD card files to PC
In CWM, you will find a Advance/ partition Sd card
Use this and make a 128 mb one, Reboot to CWM and CWM will recognize your card.

thank you very much....really helpful
Please help me i have a similar problem. I tried to partition it and it worked but it wouldnt recognize my sd card. Idk what happened maybe i formatted by mistake and now i dont have a system (or atleast it wouldnt boot up) and i have a cwm that doesnt mount recovery so i cant flash.
please someone help me! i need my phone
FIXED!
Nevermind. I did it wrong. U were supposed to partition sd card make it 128-128 and then while still in advanced setting restart launcher. Then you have to go to mount the card manually through mounts and storage.
if you just shut down the device it wouldnt work.
thank you for helping me fix this demonntl
