[Q] External SD Card Wipes anything copied onto it!

Here's a weird one. I am not trying anything complicated. I just want to copy some music to my new 32GB external SD card that arrived in the post today. I put it into a microSD to SD adaptor, and slide it into my laptops SD slot. It shows up as fat32 and I drag 30 gigs of music on to it. After a long time it completes, and I check in with XP to make sure its all good. Yep fine.
However, the moment I insert it back into my I9000 things get weird. The status bar pops up the usual "Initialising SD card" message, then the media scanner comes up and completes in like a second. Then when I try to browse it from within the phone, the entire music directory has disappeared, and the OS is reporting that there is 28gb of 32gb free on the external sd. So I unmount the SD, slot it back into my pc, and find to my dismay the music directory has indeed been erased.
Any ideas would be greatly appreciated.. I need my tunes!!
Cheers,

My 1st guess is fake/faulty card.
Copy files onto card with a reader.
Eject.
Insert again into reader.
Try to copy from card. (If it fails -> card is faulty or is FAKE)

If I were to guess, when the phone says it's "Initializing SD card" it's likely formatting the card and erasing whatever data you had on it...
When you install the card in your PC, do you format it again and then copy the files? If so, try not to format it on the PC and let the phone do the formatting.

I fully agree. Let the phone format the card and then use MOUNT mode to copy the music over. It seems Fat32 (formated on PC) won't work well for our phones prob due to a flag setting or something the like too big cluster settings. Let the phone sort it out.

Thanks for the help peeps. Here's what I've tried:
Xan: I tried copying files to and from the device using my PC's card reader, and found no problems with it. It is a Kingston MicroSD SDC4/32GB bought from a reseller on Amazon. Are there any tools for around for the pc to run diagnostic tests on SD cards? Maybe I should give that a go? But from the looks of it I think the error lies in the phone somewhere...
An Droid: I am inclined to agree with you. In my original post I stated that it said "Inititialising SD Card", this was a mistake, as it actually says "Preparing SD Card". I have tried formatting it from both the PC and the Phone and still get the same problem.
Icky Boo: I tried this method last night. Used the USB Debugging mode to Mount the phone's card's onto my PC. My Computer displays the two cards as two seperate Drives. I then tried copying all my music onto it. When the copy completed, I pressed "Turn of USB Storage Mode" on the I9000, which immediately prompted the status bar to again show "Preparing SD Card". Then when I used a file explorer to look at the card, it only had about a gig of music copied onto it. It is quite clear now that in "Preparing SD Card" it is doing something strange. Is there anyway to disable this?
Also there is a directory on the SD called Lost.DIR which seems to increase in size every time this happens. Could be a clue?
Finally, just to confirm my phone is mounting it correctly, to browse the SD card from within the phone the path is /sdcard/external_sd/ right? (I understand this is the new path for Froyo 2.2?)
Thanks for the help, sorry for the essay!

UPDATE: Ok, Xan, you were right all along. Finally got a new SD card (sandisk this time, not Kingston) and it works just as it should. Thanks for the help and to everyone else too

[Q] Unable to mount SD card (CWM 3.0.0.6)

I have CWM 3.0.0.6 on an uSD card, and the Nook boots fine into recovery, but when I swap out the card to remove dual boot, I get an error saying E: can't mount sdcard. Any ideas how to fix?
-Kevin

I've had this issue myself a few times.
Typically you'll want to swap out the SD card the second CWM boots up, and if that doesn't work you may want to try flashing CWM internally instead, or simply add the files to the CWM sd card via your phone or an SD reader.

Awesome - thanks Link. Pulling the card immediately after CWM launched enabled the Nook to recognize the card I quickly swapped in.

Internal SD won't mount, partitioning SD fails

With help in this thread (http://forum.xda-developers.com/showthread.php?t=1012263) I was able to get my phone booting again, but I'm still having a problem mounting my internal SD card.
With stock JF6:
1. Without an external SD card inserted, the phone boot loops continuously at the AT&T screen
2. With an external SD, the phone will boot, but it gives notifications that it is able to mount neither the internal nor external SD card.
Using the Onix 2.0.3 kernel I tried formatting the internal SD and then partitioning it. This results in an error and Onix dumps the attached log file.
I think this may have something to do with ext4 formatting on the SD as mentioned in the threads below. The Captivate threads, however, are either left unresolved or the methods don't work on my phone. I'm also not sure how to apply the results of the I9000 thread to the Captivate.

Can anyone offer any insight?

Actually, scratch that. Now that I think about it, I had flashed to stock and then to Cognition 4.3 successfully. It was only after loading music on it the next day that it wouldn't boot. Would that just be some corruption on the SD?

Internal SD card won't automatically mount itself

So I have no idea when this issues started and it seems to happen with *all* roms I flash on my Captivate now. (I'm using CM10.0 at the moment). Basically the issue is that when the phone boots, it'll only automatically mount the "internal storage (1.46gb)" and my external 32gb sd card.
It won't automatically mount the user-data portion of the internal card (the bit the Captivate calls "USB storage" (13.03gb). However, I can mount it manually if I go into <Storage> and do it from there.
This happens all the time to me *unless* I have my external sd card removed. Then everything boots and mounts normally. If I then insert my external sd card, then that will mount normally as well.
But with both my internal and external inside upon boot, it won't automatically mount the "USB storage area" that I mentioned. That's the bulk of the internal sd card in the first place!
So how do I fix?

Is your external SD set as main? It seems like it thinks your external has priority.

Hello,
Did you fix this problem? Because i have the same on my galaxy s i9000 running CM10.1 Nightly from today (11/01/2012)
4 Day ago everything was fine, both sd´s were mounted at boot. But then suddenly ...bang... no int-sd (Usb-Storage), although i can access everything in CWM (int-sdm ext-sd, system etc.)
Maybe you know something?
Greetings, Strainhunter

Bumping because there doesn't seem to be an answer to this. Mine is doing the same thing. Running CM 10.1 RC2, 5-28 Nightly. If I connect my Captivate to my computer, then disconnect, it will mount the internal SD, but then the external SD won't be mounted. If I follow that procedure again, both SD storages will mount.
Unknown how the external SD can be set as main storage. How is that done? My ringtones are all on my internal SD card, and every time this happens the ringtones have to be reset. It's a hassle.

try this
power down.
remove sd card and set it aside.
boot the phone without the sd card. wait for it to settle down - like 10 minutes.
with the phone still on, remove the back cover and put the sd card in the slot, then replace the cover.
go to settings, storage and see if the card is mounted. if not, click mount sd card.

I'm not talking about the removable SD card. I'm talking about the internal storage.

I know. try the steps I suggested. your storage devices may have multiple mount commands that conflict with each other. try it.

Seems to have worked. Thanks!

my external SD is mounted but doesnt show folds
I have a problem with my external SD. It mounts fine, sort of. All the things stored on it are in the phone and usable but, if I go into Myers file manager, Root Explorer, and if I go to ex SD, there is only like four files showing. This is a 16G SD card with about nine gigs uses just for music and another three gigs used for miscellaneous apps and things.
They are in the phone. They are usable. I just can't access them.
Is this something to do with permissions? Read and write? It does the same if I move it to my other phone. Any help would be great. Thanks

[Q] {Q} SD Card problems

Hello Guys.. I have a little problems here.. hope some of you could help me..
Everytime Im restarting my XZ1.. the sdcard wont load and display on ES File Manager and other file manager to..
I should reinsert the sdcard after restarting the device.. Is there any way to solve my problems..

Hi,
Have you tried going to Settings -> Storage and mount SD Card from there, instead of removing and inserting it physically? Also, have you tried to wait a bit before removing the SD Card? Sometimes the system takes a few minutes to fully finish boot (never happened on my Z1, but happens a lot on my Nexus 10), so maybe your system is leaving to mount SD Card later. Just a few ideas .
All the best,
~Lord

If you have recently update your firmware chances are you will need to flash your recovery again, I have noticed that the recovery the SD card are linked, so if your phone is rooted and you have Nuts recovery, and have recently updated then I would suggest re doing the recovery only that should bring back your SD Card.
