SD card gets "lost"? - G1 Android Development

On the average once a day my phone "loses" the SD card. Things will be working fine, but then suddenly it won't be able to find the apps I've got installed to my ext2 partition, nor will it be able to see the fat32 partition.
When it happens, I've got to shut the phone down, take out and reseat the card.
I've swapped out my sd card and tried another one and it's exhibiting the same behavior, so I don't think that's the issue. Seems to have started happening around the time I installed the JF 1.43 update.
Anybody else having this issue? Or could it be that my phone's just starting to go bad?

sounds like hardware to me :-/
hopefully someone has a tip you can try

That's what it sounds like to me. It's annoying but usable at this point. If it gets worse, though, I guess I'll have to send it back and get a refurb unit.

I had the same problem with the sdcard the phone came with but it went away after upgrading it.

I had this problem too and what I've found may sound really stupid, but keep in mind it's an observation, not a statement of fact...
It seems that the SD card is REALLY sensative to temperature. I live in Vancouver and over the the winter, we've had anything from below zero to above, I've noticed that whenever the phone was in the cold, the SD card would never stay mounted, but recently in the warm weather, the I haven't had a single problem with it becoming "lost" sounds stupid, but it could be your problem to if you live in a colder climate. Mind you it still gets lost, but a simple reseat of the SD card normally fixes this for me.
Meeker

I've had a similar issue wasnt sure what was causing it. The I noticed that I fiddle with the sdcard door. After doing that the card wouldnt show up anymore so i think I dislodged it slightly. Never know could be the issue.

Micro SD card wont stay in...

Got me a Gtab today and the micro sd card wont stay in. I push it in all the way, with the contacts to the back of the device and she just keeps popping out. I tried another card and it did the same.
Whats the trick to keep the micro sd card in the slot ?

There is no trick - once you insert it all the way in, it should "click" into place. You might actually have a defective device.

Push it further into the slot by a couple of millimeters, below the top of the slot.
Then you will here the "click".
Thanks...that worked! Used something to push it in further than my nail could reach and she stayed in.
Thanks guys
I have the same issue. At first I thought it wasn't being pushed in far enough, but even bottomed out it would not click. I have a friend who had the same problem and his magically worked one time and he hasn't taken it out since.
I found that if I come in at a little bit of an angle I can hear a very quiet snap, then when I take it back out and put it in normally I get the normal click and it stays put. I have repeated this numerous times. It is almost like the internal clip sticks to the side and needs to be convinced to pop back out a bit so the card can actually engage it.
Of course this is all conjecture, I have no clue how the locking mechanism actually works nor can I see in the slot well enough to see if there is something funny going on in there. So my observation is purely touch, feel and sound based. I would be interested if anyone has a different opinion or suggestion as I'm a bit afraid to pop the card for fear it will not go back in the next time.
I've had several GTAB's and never had a problem, but it takes a bit of trial and error to get it just right. The sad part is that they could have moved the mechanism just a bit and allowed the SD to protrude, and it probably would have fixed this problem.
I can't cut my nails, for fear that I won't be able to get the darn thing out.

I used a screwdriver to get mine in. You really have to push it in quite a bit farther than you would think necessary to get it to lock.
One word......toothpick. Does the job nicely, cheap and disposable. Plus, you can walk around looking like Dusty Baker.

Problems with MicroSD card

Hey guys, I've been having problems with my memory card lately. The one that came with the phone got damaged (due to me putting it into my card reader backwards) so I got a new one from Walmart. Since then I've had a lot of trouble. It worked ok for a day or two then at work one day I took it out of my locker and it said "bad removal". The card wasn't touched, it was just sitting in my locker. It has happened again a few times. I can temporarily fix it by reseating the card in the slot but it comes back. Now that doesn't even work. It just comes up saying I don't have a card. I've ruined my otterbox case trying to get this working (it won't grip the phone anymore because I've removed it so many times) and I'm very annoyed. I figured I'd ask if anyone has any idea what could be wrong before I go back to Bell with it. By the way, the phone is stock Android 2.2
Edit: Just realized I posted this in the wrong forum. Mod please move?
anyone got any ideas?
What brand of card did you get? Some cheap cards are notorious failing long before their time.
Maybe its defective. If its still pretty new, try to exchange it.
The other issue is that maybe you damaged the card tray when you inserted the card backwards.
This really sounds like you got some b-ware. You should return it to your dealer.

WTF is b-ware?
Well I went into Bell and they suggested I try another card so they got one of theirs and it worked fine. It's been okay so far so I guess I'll have to keep it. Only problem is I got a 4gb instead of the 8gb from Walmart for the same price. They wanted another 20 for the 8gb. The guy wasn't totally sure what it was but he assumed it was that their cards have been tested with each phone to ensure they work whereas the otehr is just a generic card. And he mentioned something about it being class 6, whatever that is.
My G2 has been experiencing SD card issues for a month or two now. I've been exclusively on CM7 nightlies, but since nobody else seems to have had this issue, I assumed it was me. Usually when using something that accessed my SD card, the phone would "unexpectedly" remove itself. Sometimes a reboot would mount my card again (can't mount through settings), but oftentimes I'd have to wait it out and reboot after a few days/reboot 20 times in hopes that it'd read it. I would re-set my SD card in the slot several times, but it doesn't do anything.
I'm still at the mercy of it and am contemplating unrooting my device to bring it in for warranty because it is a very big issue that is crippling my phone. I purchased a new SD card, but the problems still persist. Multiple data wipes/rom changes have occured as well as formatting said cards, but it's all the same.
Right now I just flashed CM7 stable (card was working [it plays funny, but if I try to use the camera, it usually dies]), and I hope that my card issues are gone, but I am fairly confident it's a hardware issue.

problem with apps stop working

Just got the phone 2 days ago, downloaded a number of apps from Android Market, moved the ones to SD cards that I could, but after a while, a lot of them fail to start with the error " has stopped unpectedly" when I try to launch. Used same apps on my 3G slide without issues. Have done charging of the phone during that time... And I'm using the same SD card I used in the 3G, so don't thinki its the card..
Any ideas out there. An issue with the phone??
I cleared the problem by remounting the SD card via the settings command. So still a question of is there an issue with the phone losing the SD mount or possible I need to try another SD card. If it continues, I will try another card...
I've had my sdcard randomly unmount on me a couple of times.. It's happened on both my first and second MT4GS, but it's very infrequent.
Doesn't seem to be ROM dependent, although i've been running stock modded my way for a little while now. I think the last time it happened to me was about 8 or 9 days ago, and it's happened 3 times since I got one in the first week of august.
I had it happen to me the first time before we had S-OFF for the phone, so it's nothing any of us did.
I wasn't worried enough about it to look into why or do something about it...though I was keeping track of how much it happened in case that changed. Now that I see i'm not alone maybe we should see what's going on and if it's something to worry about.
I've had a different memory card in each time it happened, one PNY and two SanDisk cards ( 8 and 16 gig). I don't remember what I was doing when they happened, or how long the phone had been on.
I don't mount/unmount the card manually while the phone is on, the only time I ever swap them is when no battery is in the phone. ( overkill, I know, but having seen someone pull a hard drive from a running x86 machine...I just have the methods i'm comfortable with.)
Has anyone else experienced this? If so, see about throwing some details about it here.
Thanks for the post. Its been good ince I remounted yesterday. But when I thought about it, I did remove the card with the phone powered off and put it back in beofre the problem happened yesterday. Now the apss were working after that, but stoppedworking later on then I remounted. So it could be related to the card removal/replacement. I will not remove the card anymnore aand will see if the problem occurs again..
FYI - Im using a 16GB sandisk
Depending on which apps you moved to the sdcard that could be your problem entirely. I know if i try to move system apps or widgets or something like that it'll cause it to fc every time. i try to keep as many on my phone as possible except for games and crap that aren't in any way essential to the phones functionality and i know i'm not going to need access to very frequently since putting things on the sdcard affects their speeds.

SDcard "read only"

Anyone else getting this error? I've gotten it a few times and it's been taken care of each time with a reboot. This morning it wouldn't fix it.....ended up taking the card out of the phone and connecting it to my pc to see if it was truly messed up and it wasn't. Copied it to my comp and put it back in the phone, works now. I'm backing up all apps now, contacts next. I hope this gets fixed soon or I might have to get a different phone cause I damn sure don't want to have to take my phone apart everytime this happens.
This happens to me too. Haven't nailed down what it is but I have a feeling one of Motorola's phone sync/sharing apps is the culprit.
Kinda aggravating huh?
read my post on this page here:

I think i'm just gonna try a different microsd card and see if the problem persists.....perfect excuse to upgrade to a 16gb card from my 8gb one

I9505 overheating? Check this, you never know...

Hi everyone,
I just wanted to let you know about what I have found out.
A couple days ago my I9505 started to overheat a lot, although it was not used and in my pocket. At first I thought it was the battery, so I switched it off and took the battery pack out, but it turns out it wasn't hot... but the phone was! Especially the upper part (around the camera, and even on the screen side). I waited and restarted the phone. After a while it did it again and my phone rebooted by itself after a few hours, which was a complete surprise: I have been running the last stable version of SlimBean, which is awesome and really stable for the past couple of months (the reason why although I have tried some KK based rom I ended up going back to 4.3).
Anyway, I though maybe something was wrong with my settings and I decided I would test a few KitKat ROMs, and so I did:
- SlimKat
- OmniRom
- CarbonRom
- AOKP
- CM11
- and a few more...
With all of them, I experienced the same issue. And I had them all for a few hours, because I know at the beginning the phone always retrieves data and apps from google servers, so I figured it was bound to heat, but not that much! And the random reboots happened in all of them.
This morning, I was ready to flash back to a stock ROM to have the phone serviced (I have knox tripped but I don't care, I don't think they would mess around with me about it here in Europe, at least from what I've heard, and anyway, I'd just tell them that Kies did it ), when I realised that Hey! the day before it started, I was unable to copy/paste all the data from my 32GB microSD card to my computer using the USB cable. I would systematically get an error saying that the device has been disconnected from the computer. I had even wondered if my USB cable was damaged, but seeing that the phone charged alright, I did not pay too much attention to it.
I started to investigate the card and retested some ROMs I had tested previously. This time I would not connect, but I did try with and without the card, and BINGO! every time I put the card in, it would overheat.
I then tested my card with an adapter in my computer, and there seemed to be something wrong with it, because even then the copy operation would hang! So I formatted the card (after I had backed up everything I could), and put it into the phone, where I formatted it again with the phone. Now the card has been (albeit empty) for a few hours in the phone, and no overheating or random reboot in sight (running the latest stable SlimKat).
So if your phone starts to overheat, especially the upper part, check what happens when you remove the SD card.
Hope I'll have helped someone with this. If you don't hear more about me in this thread, it means everything's alright. I'll start re-loading things on the same microSD card. I'll see if it is still faulty or if the phone heats up. If it does, I'll try with another microSD and see if it does the same.
Cheers!

Do tell me if the micro sd card is the problem. I have this overheating issue since a year and haven't been able to sove it. Yet. But i remember trying to rovercome this issue by the micro sd csrd method, it hadn't worked..
Anyways, this issue with s4 is too common, i know 10-15 people with the same issue, so i think its a hardware fault..

Thanks for this, very useful advice. Just recently I was having some issues with my phone not writing to my SD card and the card inexplicably filling up with data. It turned out to be corrupted data in the Android folder, so I backed up my stuff, formatted the card etc and that fixed it (as well as freeing up about 6gb of space on the card)
After reading your post it occurred to me that corrupted data may have been causing overheating in your phone, due to the card constantly being read over and over.
I didn't experience any overheating myself but it could well be the same cause. Either way, definitely worth checking if you're having overheating issues.
Very interesting. I for one reformat my SDcard every 2 to 3 months. Just a simple maintenance that i like to do. This is something good to keep in mind and thank you for sharing mate.

So! Some more info on this (just in case someone's interested), but first FYI Armaan.ag, the card seemed to be the issue.
I had another microSD card of the same capacity, so I copied every single file that was on the faulty card to my computer, and I noticed there were two mp3 files that were in fact not really mp3 files, but rather some junk that the phone must have created at some point.
I deleted these two files and copied all the rest to the new card, and it works just fine. So at least it's not a hardware issue on the phone: it reads the card content fine and does not overheat (well, IMHO a phone should not overheat when it encounters a corrupted file, but that's another issue)
As for the first (faulty) card, I have formatted it (full format) and checked it for errors. Windows tells me it is fine. I'm now copying all files back to it, I'll test it when it's ready. If it still crashes my phone, then I'll try on my wife's phone (I9300) and see what it does before I return it for exchange (the card is not even 3 months old).
Cheers!

When the OS is indexing files on the sd card the CPU will be working, if there is corrupted data on the card, it can interfere with the data indexing and cause the OS to read the card over and over. This will keep the CPU active for longer than it needs to be, and when the CPU is active for extended periods of time it can cause overheating.
Alternatively, the overheating could have been caused by a physical fault with the sd card reader or the sd card itself. Either way let us know how you get on.

Everything fine now
Just thought I'd let you know after re-formatting the card:
Complete format with windows, then erase card on the SGS4, which then complained that my card must be formatted, so I formatted it with the phone.
I've been going with the original "faulty" card for more than a week now, and I have had no overheating issue. All the files (except the corrupted files) that were on the card when the problem occurred are back on it. And no issue.
Hope this helps!
Cheers!

1.this is a 7.9mm phone
2.the back cover is thin as a sheet of paper
3.the sdSlot has been installed behind the processor (for speed reasons) and it's made of metal components so there s heat transmission
just replace your cover with the stock one of the 9505 black edition and tell me ..anyway i wanna try this solution tnx in advance

You're not wrong at all, but the fact here is that there was a real problem: it was really hot AND there was a huge drain on the battery, which changing the back cover wouldn't have solved.
Besides, I no longer need to do anything, since after formatting the card, it's back to normal, i.e. no overheating. But you're right that heat reaches the surface of the back cover when e.g. downloading or watching streamed videos for some time.
Cheers!

The i9500 overheats too, so I'll cehck if the SD Card is the problem next time it happens. Thanks!
