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?

SD Card cannot be read and G1 firmware does not boot up (almost bricked)

Hi guys,
First off I want to say this site is great in what it is doing for the mobile phone world! This is my first post and I am a noob so be gentle haha! Well ok, i've messed up my g1 phone and its almost bricked. I think I have identified two problems:
Problem 1:
I was trying to partition my sd card using a method from a site called theunlockr.com. Where they used the apps2sd software:
http://www.youtube.com/watch?v=w_7n1g8jXgY
After performing the procedure, my 2 gig sd card cannot be read on my computer (comes up with "insert disc") and cannot be read on my phone as well. My SD card is completely wiped and I tried formatting it again but it still cannot be read.
Problem 2:
I tried to reboot my phone and now it gets to g1 tmobile screen but no further. To turn the phone off I have to take out the battery.
I can get into the recovery utility using the pwr and home buttons so I do not believe it is bricked, but as my computer cannot read the sd card, I am not able to copy any roms to make any progress.
My question is whether if after buying a new sd card and formatting it, can I simply reflash of my ROM by doing "alt & S" to make it work? The reason why I ask is whether I should simply send it back to TMob and play dumb to get a new phone or buy a new sd card and usb reader.
I am looking at it too simply and there is more to it? E.g have I messed around too much and damaged the file system links etc on my phone. Will a reflash of the cynogen rom using the recovery utility completely reset my phone and get me passed the boot screen loader to the operating system?
I had the following set up on my phone:
Firmware: Cyanogen 4.02
Recovery Image: 1
Recovery Utility build: JF v1.43
Thanks for your input!
Mepow!

Reflashing your phone if you messed up partion it will not work, if you pop out your sdcard and then try to boot it prob will, try a card reader and format and repartion or you can try recovery console and type ums_enable to try to mount your sd card while connect usb to your computer and try to format it that when and when you are done type ums_disable and then type reboot to reboot the phone

thanks tried that in the recovery console but it came up with
"ubs_enable not found". My computer unfortunately does not recognise the sd card.

You gotta type ums_enable not ubs as you said in the last post

[Q] My NC lasted all of one day.

Well day one is over and I think I might have the first bricked NC. I used CWR to flash this ROM:
http://forum.xda-developers.com/showthread.php?t=932211
I kept getting a keyboard input error and it never worked correctly. I've been reading nonstop through the forum and now my NC won't turn on.
I look through the thread again, only to find out that it is locked and in red letters it now says "just keep away from the SDcard formatting option in settings." Anyone want to guess what I did before I read that? Yup, I formatted the SD card through settings.
It says to use a certain file to flash boot again but I have no idea how to do that if the thing won't even turn on. Does anyone have any suggestions? I can't post in the thread because it is locked.
MY NOOK IS ALIVE AGAIN!!!!!!!!
Not sure what all I did but it's up and running again. I started with the partition file mentioned in the closed thread. I then did a full restore to 1.0. This then lead me to a boot loop with the grey N screen. From there I re-rooted and it almost loaded. After that I did the power +N button and it reinstalled 1.0 for me. I have since rooted the NC and am leaving it as is until Cyanogen comes out with their ROM.

you made a big mistake by starting off with that flash to emmc rom. You should have started with rooting the original firmware.
Try this to get back to stock.http://forum.xda-developers.com/showthread.php?t=931720
If this doesnt work use my fool proof guide here:
Code:
http://mrm3.net/2011/01/24/113/

I rooted the NC using Huskermania's video on YouTube. I should have left well enough alone but seeing all the videos of 2.2, I wanted it as well.
Thanks you for the link. I plan to follow every step later in the day, after get some rest and relieve some stress. My only worry is, will the Nook turn on after I pop in the SD card and how long do I hold the power button before I give up?
I'm familiar with rooting and flashing phones, I am currently running CM-6.1 on an Evo and a Hero without any problems. Before that I messed with everything from the PPC-6601 to the TREO 800W.

try this:

maybe it's like the root sd and you just need to let it run without any on screen indicators. you could pm him and see if he can offer any help.
good luck.

So I've read through everything and when I installed the SDK I had issues with my PC and getting the drivers to load. I didn't install them and went straight to flashing it, so no matter which guide I followed the driver install failed.
I'm now on a Mac and I'm installing the SDK. Any advice on how to take me from step #11 and on.? I can't seem to be able to find the Windows button fo some reason.

hi -- assuming you still need help, this CWR bootable SD saved me many times.
download this file (I think you may already have it)
http://dl.dropbox.com/u/2248236/froyo-eMMC-0.2.img
so open terminal in your mac and insert the microSD card into an sdcardreader or adapter. If you want to be extra safe open Disk Utility in the Utilities folder in Applications and erase the SD card.
then in terminal:
$ diskutil list
(figure out which /dev/disk# is the sd card)
$ diskutil unmountDisk /dev/disk#
$ dd if=/path/to/that/img/file/froyo-eMMC-0.2.img of=/dev/disk# bs=1m
(then wait an inordinate amount of time when terminal won't tell you anything and you think it is not doing anything... for it to image the sd card)
when it is done, it will tell you XXXXXX files in 0 files out
remove that SD from your computer and put it back in -- it should show up in finder as "Boot" and check to make sure a "restore to 1.0.1 zip" is on it -- if not, let me know, and I'll link you that file as well. You can just copy over that zip to the newly imaged SD card if it isn't there.
once you've got that SD card imaged with the complete-restore-1.0.1.zip on it as well, make sure your nook is unplugged and powered off -- I assume, just hold down the power button for like 10 seconds just to be safe. Put the microSD into the microSD slot and plug the nook into the computer -- that tells it to boot from SD.
you should enter Clockworkrecovery at which point you need to navigate the program with the vol up vol down power and home buttons (power is back, home is select) and go to the mount option and reformat system, then data, then boot. It always freezes on me after reformatting boot, so just power off and back on and it should return to CWM. Then go through the steps to flash that recovery zip that is on the sd card! Make sure you select "select zip from SD card" and you should be good to go.
good luck.

[Q] SenseDroid Build Wont start to the "press Volume Down"

Hey Guys,
i have a problem with installing the SenseDroid Build by jerrytan93 . it says i need to start the Haret.exe , which i do. but the start up never come to the point, that i need to press down the volume button to enter the CWM. what am i suppose to do?
Edit:
The Haret always stops saying: cant mount SD Card. Cant countinue. Tried to format SD Card again and new Partitions. Nothing happend... Another Build isnt working for me either.
Thanks anyway
Joschilly
by the way, i do have the xperia X1, so dont get it, why it wont work. reseted my phone several times by now

I think your problem is in sd card partitioning!!
You must first create a fat32 partition, then the others!!

The message "press down the volume button to enter the CWM" will be appeared about 10 seconds after you run Haret. So keep your eyes on the screen.. If you dont press the volume down, booting will continues automaticaly and then fail.

Before start installing android that Jerrytan gave, You need to make partition on your SD card to 4 parts. one fat32, and the others ext3. After done, just follow the intruction..

[Q] External sd card won't mount

After every time I restart my phone and it turns back on my phone will never automatically mount my sd card, so I have to go into setting and manually mount it myself which normally isn't a problem but every once in a while my phone won't let me mount it, when i click on the mount sd card button, it goes to another screen that has a title Reset? and the whole screen is blank. I have reset the phone, taken the sd card out, I have done everything that has normally worked in the past to get it to remount but this time nothing will work. Has anyone else had this problem, or any suggestions how to fix it?
Thanks

Same problem here

Sorry, no help for you, but I have the same problem here. Started just a few days ago. I haven't made any changes to my settings that I know of that could have caused it. Anyone have any suggestions for getting back the ability to mount the SD card?

Yup, me too, just rooted my phone trying to get cifs manager (cifs.ko) installed and working with my win7 machine (no luck w/that yet either)... since then the external sdcard unmounts from time to time and restarting the phone requires a manual mount

Fixed?
What I had to do was basically move my entire sd card on to my computer then I formatted my sd card put only my necessary things back on there and it fixed it, stupid but it got it to mount right away...oh and I formatted it though the phone erase function not using the computer, so I didn't have to take the sd card out again.

Tried the erase all, but no luck... I suspect it's related to installing busybox... tried unistalling that without success too... would installing another ROM likely fix that, and if so any recommendations?
Talking about an HTC vivid

I'm having the same issue, except it partially mounts the external card (only shows a couple of folders but not the /music folder with 2100 songs along with 4-5 other folders)...Only way I have been able to fix it is to connect it to the PC as a disk drive then disconnect it, then all the folders "reappear".
If I put the card in my tablet I have no issues.
I tried a new card but the problem is still there.
Any help or suggestions?

Problem Solved

Good Evening OP,
I had a problem like this earlier today. I finally rooted and flashed a new rom (PACman). I used CWM as my recovery, and apparently this is part of the issue. You need to use TWRP for your recovery instead. Their website is at http://teamw.in/project/twrp they have instructions located there on how to install TWRP onto your Vivid. I used the fastboot method, then changed the settings in the 'Mount' tab to mount SD Cart, Internal and Use External SD. Worked like a charm. And since it's touch based no more using the volume rockers and power button... Hope this helps! By the way http://forum.xda-developers.com/showthread.php?t=2109140 had the initial lead to install TWRP instead of CWM.
