[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] SOLVED: Connecting with USB shows only internal memorycard...

HI!
I have this problem that when I turn on the file sharing, the computer shows only internal memory card and not the external. Because the phone itself recognizes the external card I have tried to unmount and mount several times without any improvement. I am currently using the latest CM7 nightly, but the problem seemes to have started after I changed the card from 4gb to 16 gb. Any ideas?
EDIT: Erasing sd card from the phones menu helped to solve the problem.

Go Setting>Storage and remount your sd card and try???

I've done that several times....no help... android system accesses the card without problems...music, pics etc.

Did you physically remove your card and reinsert it, or just software remount?
Have you tried the card directly in your computer?
Have a look in windows device manager and see if it reports any problems. (right
click my computer and select manage)

I have tried it all and everything is ok with the sd card itself (I copied recent nightly from the computer on the sd card) also recovery recognizes is... there are also no problems in device manager...

Try to put on debugging mode. And try it with debugging mode on.
If the debugging mode is on try to take it off.
Regards Kali

I tried that also and nothing changed.... I have a feeling that it is somehow attached to me using mybackup pro... I restored application apk and data from another phone to this one and It seems that usually the application data should go to internal memory card. In this case it is on external card... so i believe that somehow the programs are still using the card when connected and do not allow phone to share it out... It's just a guess though...
EDIT: so I think the solution is to wipe everything and start all over again

So I fresh installed Rom and wiped everything and the problem still exist... still can see files with file managers in phone and when connected to computer, autorun shows only internal card...
Edit: I tried now 2gb sized sdcard and it works perfectly... the problem is with 16gb card.

Weird. Did you try another USB-port?

I tried different USB-s now and still same I found out that when I connect the phone, under my computer appears two removable disks.... if I turn on the usb connection, only one transforms to usable removable disk (internal) and the other one asks to insert the removable disk. I used the same sd card on my HTC desire with CM nightlies and it worked perfectly... could it be CM-s bug?

Sorry to ask (maby the obvious)
On Your phone.. using your filemanager (Root explorer astro or what-ever..)
Browse to sdcard
Do you have a folder called _externalSD?
On this phone, for some reason the external SD is not mounted under./ but as i said under ./sdcard/ (i.e its mounted under the internal SD card..)
Just a thought

Where the different cards are mounted doesn't make any difference. And as he said, it works with other cards (2GB and 4GB).
CyanogenMOD mounts internal card as /mnt/emmc, and external card as /mnt/sdcard by default.
When turning on USB storage, both cards should be unmounted and shared over USB.

Hi, I had the same problem with mine, and as you said in one of your previous posts, I had to do a format through the phone and as soon as I did that I was good to go.
I did use the same memory card in my old hero so this might have something to do with it... I'm not sure.

By formatting do you mean from the menu Erase SD card? On the desire I actually had the formatting request from the computer, but there was another problem (some of the rom's files were on the sdcards ext or something and I had no access to the card from the USB).... kind of a similar problem if I think back now but after changing to CM, the problem disappeared.

I forgot to mention I am running completely stock rom and unrooted (for the time being) and there is just an option under sd card & phone storage setting to format external sd card

After erasing the sd card from the phone, the computer recognized it i'm currently copying stuff back and i'm pretty sure it does not affect the recognition

I faced the same problem. I had Swapper2 on my NC, and after I uninstalled it (and cleared the data of Swapper2, just in case) everything went to normal back again.
^ a solution.

[Q] Lexar 32Gb micro SD Card HC Class 10

I have the above memory card for my N7000 (Rocket Rom v3) and am having problems verifying its capacity.
H2testw (Windows utility) verified it as having no errors and as 32Gb
ES File Explorer's SD card analyst displays capacity as 11.06Gb
SD Tools displays capacity as 11.6Gb
I have tried copying music (21Gb) to the sdcard using two methods. Firstly connecting the phone as a media device which was very slow and started to throw up errors after a while. Then secondly by removing the SD card from the phone and plugging it into my laptop (Win7) which was far quicker. This second method didn't throw up any errors BUT when I put the card back into my phone no files were found!
I am beginning to think I have a fake SD card which when plugged straight into my laptop is telling it 'Yes I'm a 32GB card' but for some strange reason allows it to copy too many files to the card without complaint. I am going to do some tests to check this out.
In the meantime is there an alternative utility which is guaranteed to verify what my card is either on Android or MS?
Thanks

Please try to do a SD card format on your laptop before putting it in your phone
It might be an issue with its storage that is preventing android from detecting the full size
If that didn't work, try to format the memory card over the phone (using settings)
Best of luck

Okay there were 2 problems, the first one was getting the memory card to be read by my note which I've now managed to do, not sure what I did but there you go, but it certainly wasn't reading before.
The second problem and this is a little embarrassing but when ES File Explorer opens up it displays the contents of the "/sdcard/" by default which on my old desire was the external sdcard but on my note its the internal memory! Not the external sdcard! To view the external sdcard you need to navigate to "/storage/extSdCard/" which is downright misleading unless you come from a Unix mindset of course
SDTools just seems incapable of picking up the external SD card and can only see the internal memory.

[Q] External SD being unmounted at boot time

Hello!
We have two phones here N7000:
Mine running Slimbean version 4.2.2.build8-OFFICIAL.
Another one (the one with the problems) running Samsung rom version 4.1.2 Baseband N7000XLT3 version number JZO54K.N7000XXLT5
My SDcard is Transcend Class 10 32 GB SDHCi, the other one has Sandisk 32GB Class 4 SDHC.
There are a few weird sympthoms I cant explain and was unable to fix:
When booting phone 2 (with the problem), it works on the first attempt, but after a second reboot - it automatically says in notification bar, that the external card can be removed - there is no option to remount it, or any indication why has it been removed.
If we insert the Class 4 microSD with the problem into adapter and into PC, it asks to format it. If we format it, the card works on the PC, but on the phone, after a second reboot - the notification pops up anyway and the card becomes unusable.
When we switch cards, and insert my Sandinsk Class 10 card into the phone 2, it worked for only the first boot - on second reboot, the notification about ejected card appears again.
His card on MY phone (number 1) - I was able to write some test,txt file and put content in it - but on the PC, the test file appears to be 0 bytes sized, and I cant even write to it...
When we switch cards back ,my phone no longer shows the external card's content.... I am not sure why, could it possibly be some virus formatting cards on the other phone? unlikely however...
These are all the sympthoms we have, and I have no idea what to make of them... please help
Could it be some kind of phone virus, toying with the external cards? something else?

SD Card issues

Hi all,
I have a sandisk SD card in my phone set as internal storage since I got it.
Today it is going funny...I can see it in the list of storage but when I browse it I don't see any contents.
I plugged the phone into PC and it shows as 22.8gb free of 119gb but also will not show any contents.
I have removed and reinserted the SD card, I have tried setting it as internal storage again but no luck.
Even in ES File Manager I see the SD card name but once selected no content.
Currently cannot try the SD card in computer directly as I am in office and don't have an Micro to standard SD adaptor card with me. I am not too concerned about data loss as all my photos are backed up on Onedrive and my music on my laptop.
Did anyone else have issues such as this in the past?
Any tips on how to resolve without having to format SD card and copy everything back?
Cheers

Ok, very strange.
In my laptop using card directly everything is there with no issues but phone just sees the 22gb empty part of SD card.
I tried another blank Samsung SD card and it works fine so I copied the data from the card with the issue and everything works fine.
Formatted the card playing up and also is fine.
So no idea why the phone decided not to see all the data on the SD card that was in it for last 6 months.
