Phone keeps disconnecting in mass storage mode

hi guys this is my first post on this forum although i have been browsing around for a few months. my problem is that whenever i connect my phone to my pc and mount it, the computer recognises it but whenever i try to add files to the SD card or format it, the phone disconnects and i have to mount it again. once i have mounted it, the whole process starts all over again and now im stuck in a position where i cant do anything with it.
has anyone had his problem before and is there a way to fix it or is my SD card faulty? thanks in advance.

Are you rooted? If so, what rom are you on? Just give us some specs on what you got.

no im not rooted, im on the oem android software. i was just about to format my SD card so i could start rooting it.

Is it the factory sd card? Do you got another card to try out? If not, try to format the card in the phone and then try it again to see if it still does the same thing.

yeah its a factory SD Card. itried formating it from the phone and now i can add files to the card but it still disconnects whenever i try to format it. is the card protected or something?

You cannot format it through the USB by mounting it

ok how do i do it then? should i just use a card reader? or is there another way to do it by using the phone? also thought i would add that it has started doing it when adding files to the card again.

You can put it in a card reader if you have one. I would boot into ubuntu and do it that way, also if you are in ubuntu you can do it through your phone.

The phone has an option too. Go to
Settings > SD and storage > Format Card
Since your stock G1, the other phone partitioning/formatting isnt available

ok thanks guys i formatted the SD crad uising the options on the phone, which now leaves me to my next problem. i have download the Rc7 file and placed it on he root of the card but i when i power on the phone holding down the camera phone it doesnt show the grey screen with the flashing options, it jus shows the screen which tells me the board type etc. am i doing something wrong? sorry for all the questions.

it doesnt have flashing options
press the power button (not hold, just press) and it should say that its flashing the image.
(look in the center of the screen, there should be a line of text that says something)
DO NOT TURN OFF YOUR PHONE TILL ITS DONE FLASHING

Btw just chiming in case it comes up as it did in the past. If you use Swapper app and have a swapfile image located in the fat32 area, it would cause DC issues or not connect right, back then it never hit me that the swapfile was being torn away from a system that was looking for it, which then gave me corrupt sd errors. (Granted it wasnt) but yea, just another thing to look out for to those using a image file still for swap.
Also how did your flashing go?

Rooted g1 no longer recognizes sd card

So I rooted my brothers g1 a few months ago and everything was great except that it could not connect to pc via usb. I told him not to worry about it but then he wanted to put music on his phone. He was messing around with the phone and he says he formatted something and now he has lost the ability to access the market as well as other apps he downloaded. For the life of him he cannot tell me what he did. So I check the sd card via card reader and I see that signed cyanogen mod (4.2.2.etc) is still there as well as other files. So I have no clue what he did and now the phone won't recognize the sd card even though its loaded and I can't flash him another rom so he can get the market back. Does anyone have a clue on what I should do???? Please help!!!!!!!
also tried other sd cards formatted to fat32 and fat with no luck.

i guess you gotta try a sd adapter, and put the files on there, as for the market app, looks like he needs to reflash the 1.6 firmware, and then reflash cyanogen if its the market apps, and google apps you are referring to.

This is a prime example of why you should never root someone else's phone if they don't know how to do it themselves. With great power comes great idiocy.

He probably formatted the ext partition. You may want to re-partition the card and reboot and see if it will pick everything back up. You may also need to start over.
When done, make a bart backup and tell him never format anything.

Thanks fort the advice guys. I'm gonna try to re partition the card. If I have to start over can I wipe to factory settings and will it return to the original firmware? if so I may do just that. In any case thanks for the input guys , love this forum.

Ok so I wiped the phone and got the market back. All the apps that he downloaded are in the downloaded section so no worries there.
I checked to see if the sd card still had multiple partitions, using a sd reader and paragon partition manager, and it does. The first being FAT32 and the second being linux. I still do not know why the phone won't recognize the sd card or any other for that matter. Any help would be soooooooooo appreciated!
Please help guys so I can get my lil bro off my back! ;P
Oh yeah I tried to re-partition the card with the paragon manager and its not going through. Any other type of manager I can use. I'm on windows7 64bit. This is really frustrating and I wanna get this fixed. Also when I plug the usb cable will recognize the external drive but when I click on it it says please insert drive.

[Q]Nexus One can't detect any sdcard

Can someone help me how to fix this problem. Before my sdcard keeps crashing, I just format it and its good again.but now My nexus one can't detect any sdcard. I tried sdhc of different sizes even sd only but still no luck. Problem started to happen when i install custom rom CM7...

Have another rom on card--put there thru pc if necessary
btw does the pc recognize card
if you have a known good rom on card, reformat with sdformatter with full erase and size adjustment on. partition card with 0 swap, maybe 1gb
with card back in phone wipe system/data/etc etc a couple times and flash new rom

Wow, reading comprehension test fail. Dude's phone does not recognize any SD cards he throws at it.
OP -- let's hope beyond hope that the problem is not hardware but software, something to do with the new ROM you installed. First, remove your SD card and reboot into recovery (if you don't know how to from within the OS, then just do this: 1) power down; 2) hold volume-down and power until you see the phone turn on; 3) choose recovery (either clockword or Amon Ra, if you have CM7, right?); 4) wipe data / factory reset). If it still doesn't work...you might be out of luck. I don't think you can actually flash a ROM without using an SD card...even manipulating the recovery through ADB requires that the ROM be located on the SD card.

I understood what OP said--
I am saying start with fresh card and then fresh install of different rom
I am not sure if he can get that far based on his comments, but I would try.
Can you still boot into recovery with no sd card? If so, as mentioned, do that with new rom on card, then put card in phone and mount it thru recovery, then flash rom after wipes.
Don't have a solid answer just options.
I have done every crazy thing I can think of to get phone back up and running and sometimes wasn't sure which step actually fixed it. Just that somehow I am still in the flashing business.
Definetly wipe system also------I do ALL wipes 3X--just my preference
And correct in that no SD Card, no place to put rom on N1
Hope you get it working Unleashed24

[Q] Sd card appears damaged and reboots phone

Recently i bought an 8gB class 10 sdhc card. Put it in my phone it was working fine. I copied all the files from my old card exacty as they were mounted the card again and the phone says the card is damaged and reboots all the time.
I put it in a friends samsung galaxy3. The card worked fine and all files were there. So obviously it has to do with my phone.
I'm using gingerdx the latest version with stock kernel.
I'd appreciate all the help you could give me guys. Thanks in advance.

try to format your sdcard (backup fist)
don't perform quick format..
still can't try format using phone..
then make a partition..
on developer forum we have a [guide] how to partitionning sd card

Nothing. I tried what you said I even reflashed my rom and worked it with no extra apps but phone still restarts when i try to move an app to the card.
I don't know if it's significant but i noticed that: I went in cwm and tried to mount sd-ext and I always got an error. Tried to format it again error.

do not perform any activity in cwm regarding sdcard it is not compatible,even format sd ext it will give you a result of damage sdcard for some rom or your current,resulting to reformat your sdcard,now backup all your files to pc,reformat your sdcard through your phone,unmount sdcard t then erased sdcard,then back your files...Hope it help...

Go to advanced in cwm and go to fix permissions. See what that does for you.

Guys thanks for all the replies. Nothing seems to be working though, phone keeps rebooting. Might just be a faulty sd card, but that would be the second in the row.

[Q] Internal storage and ext sd wont read.

Ok first off I have read through a lot of different forums from here and different websites. Could not find a solution.
MY cappy was rooted and I was running cm9 on it for a while working great.. decided to give cm 10.1 a try. Well it worked for about 2 1/2 months. doing the updates that came out every day. Then the other I was playing a game on it. I stoped the game unplugged the phone from the wall charger went outside to smoke and went to check the phone. It was a black screen where it was semi light up though.
I of course tried hitting the power about 15 times no response. So I took out the battery and put it back in. It rebooted into recovery. So I hit reboot phone. Went back into recovery. Went in cleared cache and dalvik cache rebooted. Went back into recovery, so from there I went to install zip from sd card. there was nothing on sd card.
I then put it into download mode and using odin I brought it back to stock 2.3.4 after odin had suceeded it installed everything on phone. But it came with error no internal storage found. It booted fully. So then I tried heimdall one click it then did the same thing I cleared cache and did a factory reset. IT rebooted fully.
It only works when I have my ext. SD card in the phone though. If i pull my ext sd card out it will go into a boot loop. IF i put my ext sd card into another phone and back to my cappy Itll stay in boot loop. I have formatted sd card put it back into the phone and rebooted. and same thing. bootloop. So I then have to go through the process again to get it semi running. It wont read ext or internal sd card when phone is fully on.
So is there any way to get it to read internal storage again? Or even ext. I dont understand why it will run with the ext.
Any help will be appreciated Thank you.

Your issue is kinda odd, the only thing I can think of is the EU bug but that's on ICS and you said you were on JB. Either way, could be worth looking into, there's a thread for it in here.

Well I was on cm 9 then went to cm 10.1 4.2 I have no clue I looked into the EU bug tried to fix it no luck. I can put the sd card on it and flash the stock rom and kernel and it will run just without it reading internal or external sd card

the external sd card has probably got your .androidsecure hidden folder on it, possibly more. if your phone had the eu bug, then CM10 recognizes that and switches the mounts.
if you boot the phone, go into terminal emulator, type su, then type mount, and post the output, it would probably give us a clue.

No the android secure was on the phone, The external sd card was never in my phone but I was trying different things and if i format my sd card put it in the cappy then do the flash. It will work but as soon as I turn the phone off and put the sd card in another phone, It has no files. but when I put it in my laptop it says there is only 5 gb on it but it is an 8gb memory card. Then I have to format twice to get my full memory from it on another phone.
