sd card keeps unmounting from the g1

I don't know why, but at least once a day my sd card unmounts from my g1. I can't see pictures, use the camera, listen to music, and whatever else requires an sdcard. It's fine when its connected to my PC, it never unmounts itself.
Ive search google, this forum, and other android forums but came up with nothing. Only found other people with the same problem but no solution.
Its really starting to bug me and I'm not sure if its my sd card or my g1, any help would be appreciated..
i have rooted rc33 with jf1.41 with release-keys (watever that means)... this was happening before and after i installed jf1.41 with root.
sometimes it comes back if i take the sdcard and put it back in, but other times im forced to reboot. ive also had a few pictures got deleted by themselves, sounds like a fault in the sd card right?
thanks in advance

I would backup whatever is on your sd card. Then format it, fat32. See if that fixes it. If not call up Tmobile and see if they send a replacement.

Ensure the cover is all the way flush, this happened to me and I had to rub the cover from the bottom up to make it sit flush. If it is not completely closed, it will think you pulled it open and unmount the drive.

its already frmatted n fat32, but ill try again..
for the cover, ur talkin about the plastic thing that goes over te sd port right? that has a sensor?

I had the same problem so I opened the cover and closed it. Voila my card showed up again. I hope its not a continuing problem, but it sure beats trying the get the card out and putting it back in.

I just started getting this error...

When I press gallery it says my SD card is unmounted. I powered off, removed card, cleaned card and phone, then I restarted it and it worked but now I'm getting it again. Pretty annoying. Also, is this the type of issue covered by the warranty?
I ran a search on Google and nexus one general forum before posting, thanks in advance for any help...

oh wow....i just unmounted the card, then i powered down. when i powered on it said the card was damaged and i may need to reformat it.
So i put it in my laptop and it says it needs to be formatted.
Have i lost all of the stuff on my card and, if so, what could have caused this? its kind of devastating for me.
The ONLY thing i did today that was out of the ordinary was install zumodrive on the phone.
its a class 6, A Data 8 gig and ive had it for a matter of 6 months, im guessing it was the phone or an app that caused it?

Unless you were constantly removing the card while a device was in the middle of writing to it, I dont think the phone it self would have caused much damage... I'm thinking it was more likely a defective card...

bummer, so i probably should just trash it as opposed to formatting it and using it again?

i have had a card fail on me, and was able to get it back and it worked fine. seemed to be just a tad bit slower the second time around, but nonetheless it worked.
it was weird thought, windows wouldnt detect it, and my phone wouldnt either. i had to go into drive management and it was seen there. once i got that squared away and go tit formatted all worked well.
as far as saving your files, im not sure... i try to backup my sdcard about once a week (simply overwrite any files that havent changed). you may be able to use a disk recovery utility, such as the ones that are used to retrieve files from dead HDD's.

i had this problem on stock
i ended up putting my sd card in the pc and backing everything up (everything was fine even after the phone showed it was corrupted)
reformatted my sdcard
tested and still got the error
so i pulled the sdcard back out, started the phone up without any sdcard inserted. after putting card back in and booting up never had the problem again
since rooting, i've never run into this problem either

[Q] Hard crash, handset not responding at all. Advice?

I was downloading music onto my Wildfire with the Spotify app for offline playback when my handset went completely unresponsive. I can plug it to a charger and see the led light up, so it's not kernel panic. Also I hear notification sounds for incoming email and stuff. I just can't get the screen to go on.
This happened to me before and I took off the battery, which resulted in a corrupt file system on my SD card, so I'd like to avoid having to do that. Do I have any other options? I can't seem to turn it on or off. It's not responding to the power button at all.

try putting it into HBOOT/Bootloader when the device is off
( Hold Power button and down on volume rocker)
-if that works maybe try a recovery?

Problem was turning the device off without corrupting the SD card. After consulting Martin on IRC it turned out to be impossible so I just took the battery out and screwed up the SD cards.
I think the card is a lemon and the cause of these freezes in the first place. I got it off eBay really cheaply I suspected there was a fair chance it wouldn't be premium quality. Let this be a warning to you all trying to get cheap on your SD card purchases.

haha ok, im glad you got it fixed though, i will always try to buy the sandisk micro SD cards in future

32gb micro sandisk not mounting ??

hi,just tried my new 32gb sandisk & it wont stay on,i plugged it in & it says i can safely remove & when i mount it it appears as 29gb and then vanishes again,ive erased the card but still wont stay & also restarted phone ??? any ideas ? is the card a duff ?
bloody hell now my old card is doing the samething & all my data,music & videos etc are not showing ?
none of my cards will stay mounted & ive factory reset also,they just appear & disappear 16gb & my new 32gb sandisk ?
notification keeps coming up to safely remove sd card

There is a little switch that clicks down when you put the back down. Be sure the back cover of your phone is all the way one or it won’t mount.
Also once you change cards your old card will not work in your phone again (data wise).
The phone seems to marry to the card then forget the old card. I learned that the hard way when I put a smaller card in while I rooted my phone (all I did was format the other card at that point). Then I put my main card back in all my games had to be reinstalled.

You can copy all the data files from one card to the other and the phone will recognize both properly

Not that I know of. Like I said it forgot my SD after putting a new one in and formatting it. So i'm guessing one at a time.

Ah, it's actually more convenient because it allows you to change sd cards without restarting your phone.

Same, had the same issues at first, and this was the solution.

That feature is there so hotswapping your memory card won't cause data corruption.

SD Card Issue in S5

Hello All,
Im Hoping Someone Would Be Able to Help me with an issue....
ive got the samsung galaxy s5 SM-G900I with telstra here in Australia, on the 26th of last month i went to my fathers wedding, i was taking photos on my phone with the camera it spent most of its time on the camera app (once closed itself down prob due to inactivity) anyways after a while it stopped taking pictures.... the capture button on screen was grayed out but i could still see through the camera.... i though ok weird and closed the app down and opened it with the same result... then a popup came up that said "Camera Failed" when i pressed ok the camera app closed.... tried to bring it up again and it was a no go so i decided to reboot my phone..... it shut down properly but never turned back on so i though ok maybe it turned itself off so i tried to turn it back on and got nothing..... i pulled the battery out and put it back in and the phone turned on and the camera was working perfectly fine again so i though oh ok glitch but all good.... anyways i went back to taking and i found that all the pics i had taken that day were gone from the SD card...
it took me a minute to relize that all the photos on my card were gone.... i went to investigate and say that the card wasnt mounted under storage and i though all good again and hit mount and nothing happened.... then i saw a notification saying either an unformatted card or an unsupported file system... i checked in another phone with it and got the same issue and it seemed the card had gone bad, anyway i got home that night and plugged the card into my computer and found that the card was reading up as a raw file system.... so i went stright to data recovery but before the data recovery could finish scanning the card all of a sudden there was my sd card reading up perfect in my laptop... which was weird to me as i havnt seen that happen before, so i backed up everything on my card to my computer and plugged the card back into my phone and it came up with a different error i think it said something about the card maybe being corrupt.... so i put it back into my computer and ran a chkdsk on it and it showed that everything on the card was corrupted..... so i decided to wipe the card and start again and i transfered everything back onto it and everything was working perfectly fine as if nothing had happened...anyway fast foward to monday this week and i went to take some photos and recorded a video on my phone (went stright to the SD card) and i checked it afew hours later because i got busy and i had found that everything i had done that day had corrupted and photos that i had taken about 4 or 5 days ago were also corrupted... images that i had seen to be working fine.... so i backed up my SD card again and though ok im gunna have to buy a new sd card and i redirected the save location for photos back to internal storage.... anyway today my SD card was still in my phone... all of my music is on it still and i was listening to music while i was heading out to the shops.... and i noticed that afew of my songs were playing for a second or 2 then skipping to the next or just pausing and throwing an error about the song being corrupt...
so i put the SD Card into my Samsung Galaxy Tab S and the songs that were "Corrupt" on the SD Card were working fine on the tablet..... so i am wondering.... is it the SD Card or the Phone?
thanks Help would be amazing!

sorry about that.... not the best when it comes to that lol, i just edited it i hope it makes it easier to read

I'm not trying to give you a hard time, but that is still hard to read. If I got the gist of your post, you had a camera failed message and apparently SD card corruption.
There isn't enough information (or maybe it's in the middle of those paragraphs) to tell what happened. Probably just a temporary glitch, but you could have anything from an actual camera failure to a physical SD card defect.
Try clearing your system cache. I wouldn't worry about the failed camera message if it doesn't recur. If it does, search for the camera failed threads, Samsung was providing warranty replacements for some early production camera failures.
If you are searching for photos, see if your phone put them on the internal sdcard (since the external SD wasn't accessible). Otherwise you could consider a data recovery app to see if photos can be recovered from your external SD card.
Is your external SD card bad? We don't have enough information to know yet? Do a search for an app to test the card integrity or you can probably use the fsck command to test the card and correct (if possible) filesystem errors, followed by reformatting and remounting the card. The fact that the card was readable on another device doesn't differentiate between an marginal or unstable card and a sound card. You'll have to test and reformat the card to really tell.

thats ok i know your not trying to give me a hard time on it im sorry that its so dificult to read, ill see if i can try this alittle better
on the 26th of last month i was taking photos for my fathers wedding when the camera stopped working, it wouldnt let me take photos so i closed the camera app and opened it again thats when i got the camera failed message
i tried to reboot my phone but it froze during the reboot and didnt start up again so i pulled the battery out and put it back in, when the phone started up again the camera was working perfectly fine but the SD card was coming up as unreconized file system or unformatted,
i got the SD card to my Laptop and the File System Read up RAW i started data recovery and while it was scanning the card everything started working again and i got all my photos back without the need for using data recovery
put the SD card back into my phone and it read corrupt so i reformatted it and restored everything back into it and the card worked fine,
Fast Foward to Monday This Week and i recorded a 10 minute video at 1GB size and took some photos.... and they corrupted.... no issues with the camera or anything like that.
Today i Was Listening to Music that was stored on my SD Card (64GB Class 10 Transcend) and it skipped a song about 2 seconds into it and another song it tried to play and failed coming up with an error about it being corrupt, ive taken the SD Card out of my phone and put it into my Samsung Galaxy Tab S and the songs that were "Corrupt" worked perfectly fine on my tablet
so im wondering if it could be the SD Card or the Card Reader in the Phone? the System Cache in the phone has been cleared.
Thanks i hope thats helped you able to understand it better and again i am sorry for my poor writeing skills

Thank you for going through that again.
The basic question or mystery that we are trying to solve is why does the external SD card only appear to have problems in your phone and not the tablet? And how can we tell if it is a card issue or something other aspect of your phone?
While it could be some problem with your phone e.g. bent or damaged SD card slot, corrupt driver or other causes.. it would be hard to track down without further hints. i.e. there are so many possible causes that we need to narrow it down.
So it's easier to tackle this by elimination. Lets test the hell out of the card because that is easier to do.. and despite the fact that it appears to work in your tablet, it's still more likely to be a card problem. Why would it only affect your phone and not the tablet if it is a card problem? There are lots of reasons, but just to give one example.. it could be a problem on just one area of the card.. and that happens to be where your phone is preferentially storing files.
If that makes sense so far.. then the plan is to see if we can identify a card defect. So.. grab an app that will check for file system errors (chkdsk, fsck, etc), check partition structure and do extended read /write tests on the card. At a glance perhaps one of these apps: Lewy or Dewy.
Most likely you have some bad clusters which fsck or chkdsk could repair. But it's best to run an extended card test.. that may take a few hours but it's still a lot quicker than trying to search for all the possible causes of phone problems. If your card passes with no issues.. I'd be inclined to back up your phone and then install a brand new, 100% fresh and stock firmware temporarily. That should in one swoop tell you if it is a hardware or software issue. Again, we are looking for expedient ways to narrow down the possible causes.

i will give u a hint ... try to make your topics, in your case, a loooooot less than your post so a lot more people would help you.

Im Sorry it took so long to reply to you, The 2 apps u suggested did not work they wouldnt detect the SD Card, i put it into my laptop and backed up my data and i ran a chkdsk on it and it came back clean said nothing was wrong with it, i have hard disk sentinel installed on my laptop and ive run a surface scan on it that is doing read write read test selection on 2 passes and has been running all day.... the first pass came back clean on it but the second pass has picked up 4 bad blocks near the end of it... its come up "7/08/2014 9:43:09 PM ! Verify error, Sector: 99480300" afew times with different sectors on it, im wondering if the camera issue i experenced could have caused my card to screw up like this? or even the phone not booting back up without taking the battery out first after the camera issue happened? would you consider Transcend a good brand for SD Cards? mine was a Transcend Premium 300X Class 10 Micro SD Card 64GB, im thinking of getting a 64gb Samsung Pro Micro Sd Card now... are those good?

Hey mate! finally i have someone who has the same issue as me! this happened to me last week. i was going through my photos and they looked to be all corrupted. i didnt take much notice as i didnt really need them. i was at the gym and my music was all gone. it was all saved to my samsung 32gb SD card. i got home and there was a message saying SD card is damaged. i lost everything. i did a format and nothing happened. it still said SD card failed.
i went and bought a new Samsung Evo 32gb SD card and it is doing the same thing. i plug it into my laptop it works fine. when i chuck it back into my s5 it says its corrupt. i have no idea whats going on. SD card reader in the phone maybe damaged somehow? i dont i have ever dropped my s5. its driving me mad.

My wife's 64GB card is now doing the same. Formatted and working twice. Images all saved to cloud but a pain waiting for it to happen again.
Ordered a new 64GB card today. Hoping that sorts the issue. If not its return to store time. Happy knox is intact.

my galaxy S5 does not read SD card also..
i think most likely is the software issue.

Just wanted to chime in here. I have a hardware failure with my s5 SD reader, and it was my fault. I had to replace my digitizer, hence putting My Straight talk sim into a temp phone for a fee days.
I cut my sim down to nano size for the temp phone, then stuck the now nano sim back in the s5 after repair, I didn't have a sim converter, and ended up bending pins. Thankfully the sim still works but I toasted my SD slot. Not only will it not read any SD card, it breaks any working one i put in it. I'm a hardware guy, so I'm going to give a go at fixing it, but I'm pretty sure the whole assembly is soldered to the board, no replacing this assembly. At least I don't believe so.
