Phone keeps disconnecting in mass storage mode - G1 Q&A, Help & Troubleshooting

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?

Storage Card contents dissapeared. Help!

all of a sudden i realized my storage card's content (2GB) just dissapeared.
I have over half of my non OEM programs installed on it and i cannot use them.
has this happened to anyone before?
how do i fix this?
thanks
Well... It happened to me in some way, but after about a minute all was back again. Don't really know why. Maybe soft reset would help?
I had that issue a while ago, apparently it was gone, but the space was still occupied. I didn't find a solution so i had to reformat it and it never happened again.
This exact same thing happened to me yesterday; all of a sudden, when using Resco Explorer, all of the contents of my storage card disappeared. The card looked blank. However, it also still looked like the space was occupied - meaning I did not have 6 GB of free/empty space - just no content. I re-formatted the card on my desktop and am re-syncing now but I have no idea how or why this happened. I have not recently installed any new software.
Nothing disappeared. Turn off the phone, take the card out and put it back in, then turn the phone on. Did you even soft reset first?

Tried it didnt work. I guess i have to re format
This happened to me and it was from a loose card and a soft reset found my data.
Soft reset didnt help. I tried a hard reset and Nothing. Its like my device cannot recognise my sd card at all. when i check in the setting it says the storage card is not installed.
what do i do?
I can say that it happened to me because I installed a P2P program and it froze and I had to reset. THen my sotrage card got messed up.
It's like any flash memory. If it's in the middle of writing and your phone gets turned off or something then you will corrupt your data. I don't know if you can buy some third party program to get your stuff back. maybe.
????
I had this problem too.....Here's a couple of things you can do
1) take out sd card , take compressed air and blow a little air inside where sd card goes , put card back in and do it slowly wiggle it ever so slightly , take out sd card and do this one more time , this worked for me.
2) in file explorer under "storage card" look for a file called " MSMETADATA ...and DELETE it for some reason this file freezes your device from reading you card
3) go to windows media player and go to library and update your library , see if your sd card shows up there , thats the way I knew my phone was reading my card
4) bad card....I have had a bad card before and it was doing the same , I bought a new one and things got better
good luck my friend

this happened several times on my 8525, and once on my tilt. I've never pinpointed exactly what happened, but it IS a big problem that was supposedly fixed by HTC on the tilt.
I stuck the card in my computer and ran some data recovery tools. They dont always work, but you get lucky sometimes. I then formated the card and copied the data back.

I turned the phone on and off several times and did several soft resets; I also went into Windows Media Player and attempted to update my library but it would not read my storage card. Neither would the "HTC Audio" program, or CorePLayer, or Resco File Explorer/Photo Viewer; nothing would even recognize the card. Also, when I used a card reader in my PC nothing appeared either. I had to re-format and re-copy my files.
Hey guys, thanks for your advise.
Im gonna buy a new microSD card and see if my kaiser recognises it. Hopefully it does. If so thats great.
Just hope its not the phone with the problem.
i'll let u know whats up
by reformat...do u mean hard reset?
Try this:
With the card in a read/writer or adapter that works (not the phone), go into DOS: Start>Program Files>Accessories>Command Prompt or Start>Run and type in CMD and Okay.
Change the directory to C: drive (i.e. cd\C: )
Type chkdsk e: /f /r at the c: prompt (e: is whatever your card drive is).
Let it run. If it asks about saving a file, you may as well say NO as it will be corrupted or a partial file.
Then EXIT and try the card. Data, for the most part, should still be there and not destructed like FORMAT will do.

No - by re-format I mean I inserted the card into a card reader and re-formatted it as "FAT32" on my desktop PC. I tried to do his on my phone first with SK Tools and MemMaid but neither would recognize the card.
Well. My SDcard (scandisk) is not recognised by my phone or my card reader, so i could not format it.
I bought a new Kingston one and my phone recognises it.
I guess it was the card after all.

I had the same problem: after something went wrong with an install file from my card on my Kaiser, all files on the card were deleted.
I was able to retreive the card content on my PC (from a card reaceder) with the free program "PC Inspector File Recovery".
After that, I restored the content to the card. I performed a checkdisk (see Mack5305 above). I then removed the directory MSMETADATA.
After this, I could use the card again.

SD CARD won't FORMAT

Okay well this is my first time on this forum better yet my second day having the G1 and I've already seemed to get in trouble with this phone. Okay well I was attempting to jailbreak a G1 with no data plan. After I had put the Dreaimg file in my F drive I had to go to that rainbow screen and all. After that the phone was locked again so I activated my phone VIA WIFI using Jesus Freaks thread. Then after I got back in the phone I continued to attempt to jailbreak/root my phone so I tried to put the recovery.img and upload zip file in my F drive but it said something about an I/O error. I kept messing with it trying to think of solutions now when I try to click the F drive it says, "The disk in drive F is not formatted. Do you want to format it now?" when I press yes and check "Quick Format" it crashes my computer. I am on an XP computer. PLEASE HELP! ):
Well your first problem is that you are using windows.
Just playing, you could always try a card reader. Your card needs to be fat32. If your phone still reads the card, try going into sd in settings and format it through your phone, then retry it on your computer
Its in FAT32 thus I was trying to jailbreak it. Although my phone can't read it, as it seems. When I go to SD in settings all I see is "Total Space", "Available Space", "Unmount/eject SD card". And they are all dark so that I can not press it. And I'm sure I have an SD card in there.
Ok your card is possibely corrupted, since you do not have a recovery image we can't go that way to reformat, hmmmm, card reader, I know reboot your phone, it will pull up a notice that your card is not formatted and it will ask you to format it now right there on the phone
I just rebooted it nothing happened. Also another piece of info, the problem was happening yesterday as I woke up today my phone popped up a message saying Upload now? or something like that and I pressed yes and it fixed but I did the same thing, and tried to jailbreak it, and now I'm back to the same problem. ): Got AIM to help me faster?
Don't got aim. So nothing popped up, you updated by what the ota update if so you are back to your previous build, if you are having serious problems with formating, my best suggestion is a card reader, you can get one for like $15 at walmart. Or try a different sdcard
If you are feeling froggy and are broke, you can try downloading a linux distro and burn a live cd or use unetbootin to make it on a thumb drive. Ubuntu linux has a partion editor that would be able to read it no problem and format it and even partion it for you since you will prob want apps2sd and a linux swap
Ugh I'm a big noob at G1's as I've only had it for one day now. Do you have MSN? Yahoo? something please. I need live help I don't want to brick my phone.
I don't use any of the messaginers, sorry, but the only way you can really brick you phone is to mess up installing the danger spl, anything else you can come back from, the most I can offer is my # and walk you through that way but your easiest option would be the card reader
Eh, can you message me your number?
I'll pm it to you in a sec

[solved] Card "Preparing SD card; Checking for errors"

Hi all,
I have a problem with my G1, running on latest Cyanogen mod. After restarting the card cannot be read and it is seems to be checking the sd card, if it really happens I dunno. What is weird is that I can access the card from recovery mode (shell), and it is not damaged (at least the windows doesn't detect damage while it is in the card reader. So that implies that the problem might be in the Android system.. anybody has a clue how to solve this? Thanks a lot.
Edit: solved it, deleted fsck_msdos from bin and it works flawlessly again
Can always wipe and reflash. Or if you have another sd card laying around and put that in to see if it recognizes it.
I'm having the same problem How did you delete the fsck_msdos from the bin?

your phone should rooted
then download and install root explorer
in the root explorer go to
system /bin
and delete fsck_msdos
now reboot your phone
I was having this same issue..it would typically take up to 5 minutes or more to "check for errors" after a boot.
To fix this I backed up my sdcard, reformatted, copied everything back, then reflashed. Everything was fine after that.
i have somewhat the same problem but in my case it sometimes say blank sdcard or damged sd card it read fine when plugged into an sd card reader any help
Thanks. It worked by simply deleting fsck-msdos but it keeps giving SwiftKey3 error " unable to load language packs". Keyboard still OK. I have xperia x10 mini rooted running android 2.1 E10i.

Well, after getting other errors such as "no enough space" from Platinum Backup (there was a space on SD Card), I had to go to Format the SD after copying everything. Then I copied back the important folder the SD. I also had to reinstall SwiftKey. Now everything is fine and no data loss.

Simple fix, Difficult decision. Remove SD Card from slot then Factory reset phone. Once it comes too just go through all steps to setting up device then reinsert the SD Card into the slot. BOOM!
thank you very very much it worked for me

Bloody Brilliant. I have no idea why I could not find this solution two years ago. I have spent several hours searching for this solution, several times. In my case, I needed to remove the fsck.exfat file in the /system/bin folder.
My attention span is extremely short. I have been living with a 3 to 4-minute card scan for a 256GB microSD in my Samsung Note 3 for two and a half years. For all of the reboots I have done (which must be near a thousand, if that's not severely underestimated) I have had to deal with waiting to use my phone. I can't tell you how discouraging it has been to have such a powerful, useful device crippled by such a stupid flaw: that of checking the SD card that you rarely remove, for errors, every single time the phone is rebooted, even after graceful reboots called by the "proper" methods.
I can't tell you how many times I have rebooted my phone, only to forget the reason I rebooted it, because my phone took 4 minutes to reboot.
Productivity to the cubed-root.​Pisses me off.
Someone who has more voice than me please get the Android People to change this. As of Nougat, this is still the default behavior. How can an organization be so stupid...? I have no doubt that just this flaw has sent many people to the Apple camps. Who the cuff in their right mind would want to deal with such a hassle?? Are they seriously unaware of the trend for people to actually believe that their devices, machines and technology ought to be doing things faster than previous generations?
(Please just take the following cynicism with a grain of salt. I just learned the above fix, something I really should have figured out a long time ago/kicking myself!!) :crying:
For the anally-inverted who might bring up the obvious argument that your phone will no longer be able to detect or fix corruption, all that needs to be done is the following:
1) move the fsck.exfat (or whatever the formatting) file to a different folder. In my case I moved it to the /data folder
2) use some delay scripting program that will symlink the fsck.exfat file to a tmpfs location say, 30 seconds after boot; or longer if needed. This intermediary step is necessary in order to create a temporary symlink, which will be nonexistent upon reboot.. If we didn't create a temporary symlink, the fsck.exfat command would be immediately available after each reboot (which we don't want) because symlinks are normally permanent. Therefore, this step will need to be run after every reboot (but again, time-delayed).
3) the last command is to create another symlink, linking the tmpfs fsck.exfat symlink created in the last step back to the /system/bin folder (or wherever it originally resided). So this is a symlink of another symlink. This step actually should only need to be done once, since this symlink should remain after reboot, even though it is initially broken upon reboot until the previous command recreates the intermediary symlink. It should become effective again when the previous step is run by the time-delayed scripting program.
Now your phone has the ability to check the card upon you calling the fsck.exfat routine through normal means, one of which can just be a simple unmount -> mount request from the Android system settings . Your card won't be needlessly fsck-checked to death every bloody time you reboot your phone.

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] 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

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?

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.
