Mass storage not working - GT540 Optimus Android Development

When pressing enable mass storage on the phone, or going in recovery and doing it that way, it doesn't seem to want to connect
It worked before I messed with the partions on my SD card, so i wounder what I did to break it?
My phone can read my SD card, and if i use a MicroSD to USB then it works, but not phone to computer, it makes a beep beep sound, so i know it sees it.
Thanks

test to format SD card in computer if this don't work test your phone with another SD card

After formatting the card it started working again Thanks!

[Q] Micro SD Flashing method won't work

Hi all. I just got a new X1 a few days ago. Pretty happy to have it, however, I'm having chronic problems flashing a rom on it using the micro SD method. I have a PNY Micro SD card, and after hard spl-ling my phone, I put a rom on the micro SD card in the root, renamed it to KOVSIMG.nbh, powered the phone off. Removed the battery and micro SD, reinserted everything, and when I powered it back up, I got the tri-colored screen, then it said no image file. For some reason, this PNY card isn't being recognized by my computer, so I can't reformat it with my computer. Can somebody please either tell me how to format the card on my X1 or direct me to the most current and reliable USB method thread please. Thanks.
[A] Micro SD Flashing method won't work
Hi x1-pc7,
try this:
http://forum.xda-developers.com/showthread.php?t=787867
In Summary,
try to copy all your microsd contents somewhere else temporarily. e.g. your pc desk top
FORMAT you SD card as FAT or FAT32.
try the micro SD method.
sorry, i mis-read your post, you knew all that above...
To format your sd micro card, you would need a card reader to format your sd card.
card reader that handles the microsd, or put the micro sd into a sd card adapter, usually provided with the microsd card, and put this into a sd card reader.
Hope this helps!!
Have a Happy New Year!!

Listen. I said that my micro SD does not get recognized by my computer. I have an adapter, but my computer won't recognize it. Read the whole post, and please show me where it talks about how to use the USB method to flash because the micro SD method will absolutely not work for me.
Thanks.
Happy New Year to you too.
usb method is simple
just turn device off.push the volume bottom in(& keep it in) then push power & keep both in until bootloader screen appears.then connect to usb.run Xperia Software Upgrade...Done!

You could try to change your USB to PC setting to "Disk Drive" (Start » Settings » Connections). This way your phone will only show your microSD card instead of both internal memory and SD contents.
See if that enables you to format your SD card.

Not even without the X1, i.e. when using only your adapter?
Sounds like either the card or the adapter is broken - any chance to cross-check with another card/another PC?
Make sure your adapter can handle the card: (µ)SDHC cannot be read by older (µ)SD adapters....

Are you trying to flash your phone? If you do, have you copy the new ROM to the SD card? (in root, not in any folder) And rename the ROM to "KOVSimg.nbh"
Then the boot loader mode will detect the ROM and show instructions.
However, if you're not trying to flash your phone, you don't need to enter the boot loader mode. Just do battery pull, and start your phone normally.
not dev related, therefore moved to q&a

pulling battery... external SD corrupted?

I made the mistake when my phone froze today to pull out the battery, instead of waiting for an automatic reboot. Now my phone complains that my external SD card has an invalid filesystem, or is blank... when i press that notification i get the option to format the SDcard, but i just moved all my applications to my SDcard 3 days ago, which would make me lose everything.
Is there a way to recover it without losing all its content?
I've tries a micro SD cardreader for my computer, but either the cardreader is broken, or my computer doesnt recognise the card at all...

In that case NO but a format may recover the card though it could wipe all data .
jje
And computer cant recognize the files either?
Then I'm pretty sure there's nothing to do.
so far ive found out that my laptop sees the card, but i cant access the files on it. it looks like the filesystem got corrupted or wiped or something, because looking at the properties of the card it sais: filesystem: none.
i found out about testdisk, and will try that out overnight. its a 16 GB card, so that is going to take a while.
Recuva free ware may be worth trying to recover files if card can be seen

[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] Damaged SD card

Hi guys,
I tried partitioning my external sd card to linux swap, and something must have gone wrong. Now,a notification on my Galaxy S reads "Damaged SD card - SD card damaged. You may have to reformat it." This was the first thing I tried, but the Internal SD is formatted instead when I try. (Rom bug?). When i mount my phone via USB, only the formatted (damnit) internal SD is found.
I'm currently on TiramiSlim (best rom!!) with Devil 0.94. If you have any help it would be appreciated, any further questions don't hesitate!

In first i think that partition ext sd card is useless but it's my opinion.
In fact if you want to recover your ext sd i advise you to reformat your sd card with the windows disk utility: you select all volumes, delete them and recreate a new one with ntfs format (android will do his work when you'll insert your sd in the device).
If it doesn't work try to make the same but with a Linux system (Linux is powerful ^^).
Please reply me your results.
Have you tried to format the SD card with an SD Adapter & then make sure that USB debug is enabled on the device.
I had this issue.
Sometimes it shows that the card is damaged & then it reads it later on!
I plugged the Card into my Digi-Cam Formatted it.
Changed the Rom.
Now it works.
Anyways safely remove the drive when plugged into a computer!
i don't have an sd-card adapter unfortunately, the only way i can plug it in is via my phone. I cannot seem to find a disk utility on windows that will read the external sd, i can only find the internal from my computer.
i will try and get hold of an sd-adapter and let you know if it works
fixed the problem!

how did you fix the problem?
My phone recognizes the internal storage but i keep getting "sd card is damaged, try reformatting it" in the notification bar.
when I click on format, it says "unmounting sd card" but nothing happens.
Thanks,
Luke
*edit.. nvm.
I put my SD card in my old x10 and in settings/storage I erased my SD card.
Works fine now

External sd card cant be detected

Hi guys,
My external sd card suddenly cant be detected by both my phone and my computer
I tried flashing to many different roms and still no hope
Any suggestion please? :crying:
Thanks!
Connect your SD card via card reader to PC and try format it. If you don't see files or PC don't see this card - it can be damaged.
Card reader u mean the card adapter? i don have 1 of those
and when i connect my phone along with the external sd in it
the phone recognizes it as removable disk H but i was not able to open it
does this mean its not damaged?

The file system (partition) on SD card is broken - you need format SD card

Any other method to actually format it without the card adapter?
The easiest way is connect card via card adapter to PC and check that card and files are visible. If card is recognized but you can't access to it you need format it.
You also can do this in your own phone: in settings - memory - try disconnect external SD card and then erase/format external SD card.

formating/erasing options depends on which rom you use.
When you connect phone with PC and tap mount SD card (or something like that) on phone screen, you should see card on PC - can you see it? You write that it has assigned drive letter H - right click on that and format it.
I tried that it says "theres no disc in drive H:" Please insert a disc and try again
try mount SD card with and without USB debuging.
try format SD card via recovery
If you have different SD card try it to eliminate ROM/settings problem.
i cant erase my external sd because its not detected
the recovery cant mount it because the external sd is not found
trying with and without debugging also didnt work oh my god
i don really understand the last option though
"If you have different SD card try it to eliminate ROM/settings problem."
In your case there are two posibilites:
1) sd card is damaged - logically (file system/partition) or physically
2) phone is damaged - logically (ROM bug/phone settings) or physically
If you put other SD card in your phone and phone will see it and you will have access to files from that SD card you can be shure that phone is ok
