Hi folks,
I've got a problem with my dock and my SD card. The device keeps losing the SD card, which is really annoying, for example while watching a movie. At first, I thought this was because the card didn't fit tightly into the slot, so I put some layers of tape on top, but that didn't fix the problem. At the moment, the tablet is losing and recognizing the SD card in intervals of minutes or even seconds, even when I don't even touch the dock. This is extremely annoying to me. Has anyone experienced similar behavior or suggestions on how to find the cause of this? It is a 64 Gig SDXC card from CnMemory. Unfortunately, I have no other SD card to test.
Thanks,
Hannes

I suspect the card slot is faulty because I current have a microSD card in the tablet and a SD card in the dock, both work flawlessly. I can only suggest that you use some PC software to thoroughly test your SD card just to be sure. Other than that, I can't think of anything else to do.
mybe
possibility it could be a rom issue ive seen some roms have issues with the dock itself even some stock roms there were a lot of issues with bluetooth on 4.2.1 so maybe some dock issues too something to think about

Hi all,
Ive just got an Orbit and can seem to get it to see the Micro SD card. It doesnt appear in explorer and it doesnt autorun (its the copilot card)
I had a similar prob with my mini S but putting the card in and out a few times seemed to fix that. In this case it doesnt seem to.
Is there a known issue with it not reading cards? (ive installed the SD card fix from HTC, this didnt make any difference).
Ive not been able to test with another card but anyone have any thoughts?
Cheers
Could be a faulty card.
Have you tried opening it with your PC, so you could at least see the files on it?
i was facing exactly same problem
then i found that my card was faulty
crap, i just tried the card in a mini-sd adapter in my old minis and it runs and auto plays instantly.
points towards the phone how very annoying
not a lot i can do is there?
send it off, wait
Tried cutting out a piece of paper and placing that on the back of the card so that it pushes the card/phone contacts together firmer?
got it working at last!
it seems it suffers the same problem as my miniS did. it seems to work now and again and i have to put it in and out loads of times!
works now tho!!
When I play video stored on my internal storage, it is smooth. I can watch a 90 minute movie video without noticing any glitch at all.
When I play video stored on my external storage, there are glitches. One glitch every 1-2 minutes. These are not big glitches, just a brief deviation that gets your attention. If I listen, I think it is skipping a fraction of a second of the audio. (It may be skipping a fraction or second of the video display also, but my eye doesn't detect it). It's not a huge deal: ...... but just something that I notice and it's a minor irritation.
Since it occurs only on external sd, not internal storage, I assume it is the speed of the sd card. I have a 16GB Sandisk SD card. If I remember right, it's "Class 6"
I don't hear any glitches when listening to MP3's off of external sd, works just fine with no glitch ever.
SUMMARY: no problems on internal sd, no problems on mp3's. The only problems are videos on external sd.
It seems to me that the external sd can't quite keep up with the high transfer rate required for video playback.
Has anyone else seen this?
Any observation about which SD cards do this and which don't?
By the way I'm running rooted 2.3.6 from qkster's package, with Zen's Infusion A kernel. Holo launcher.
I haven't tried boosting to 1600Mhz. I'll try that and report the results later.

I just tried it - no difference. Glitches still occurred with cpu max frequency set to 1600.
You should try to format your external card and then try again.
Also, it could be your external card is to slow on reading
Should not be that slow if it is class 6 though...
Maybe try other card on your infuse with same video file.

Thanks. I have also noted the SD card media scanner runs to scan my external sd card more frequently... almost every time the phone comes out of sleep. I think this symptom coincides with me adding more files to my external SD.
I will try reformatting now as you recommended.
Question: is it better to reformat sd card in the phone or on the pc?
(if on the phone, there is no question of file system... I'll let the phone pick the format. If on pc, I'm not sure what format to pick... I'm using Entropy's kernel with voodoo lagfix enabled... does that mean external cannot be formatted to FAT32? )
The bigger problem is the constant scanning every time I turn the screen on. It was a nuisance, and I think it was draining my battery.
It gave the error message "sd card unexpectedly removed".
There are threads on this for some other Samsung devices.

There was a suggestion Sandisk cards in Samsung devices tend to have the problem.
I transferred my files to my pc, formatted sd in the phone, no problem until I transferred files back... then problem started recurring.
I reformatted in the PC to Fat32. Put files back on. Seems to be much better. But very close monitoring using SD Card Monitor program....

... shows it is still have problems. I'm going to break down and buy another sd card. Perhaps another brand.

Your SD card has problem for sure.
It shouldn't scan that often and it shouldn't say it is unexpectedly removed.
Seems either phone's card reader or the card is very unstable. That is why you are having problems in video files.
If the SD card benchmark program shows that tour SD card is performing bad, I beehive you got fake Sandisk SD card or really low class SD card.
From this point, I believe getting new SD card is the best solution here.
PS. You should put the SD card on PC then run benchmark on PC to see how it performs on PC. If it performs too much faster on PC, then the problem might be your phone's card reader.

Symptom went away with new sd
Before replacing the sd card, I had 100+ sd card events recorded by theSD Card Monitor program in a 24 hours period.
After replacing the sd card, I have 0 events recorded by the SD Card Monitor program in a 24-hour period.
The new SD is a Lexar 32GB Class 10 for $45 at Target. (preformatted as FAT32)
It was cheaper than the $70 32GB SanDisk they're selling at Best Buy.
I'm tempted to say the problem is solved.
On the other hand, one thing I noticed on the old SD was that the old sd symptoms got worse with time... I don't think they were there when the card was new. So I'm not sure if I've really solved the problem or just reset the clock waiting for the new SD to act up under whatever influences degraded the old one. Time will tell. For the time being, life is good. That scanning upon coming out of sleep was a real PITA.. slowed down the phone just when you picked it up to use it... actually dropped two phone calls recieved while phone was sleeping.. I presume because the phone wasn't able to handle scanning and answering at the same time.
Perhaps it was a fake SanDisk. Where'd you buy it from? Lots of fakes on eBay.
I bought the SanDisk (that had the problems) at Best Buy.
I was going to post this in response to a couple of people in the development sections but my post count is too low so I'll post it here instead.
The SD slot in this phone seems to have an issue with corrupting SD cards, I've had to format both my old and new SD card multiple times with this phone as it becomes unusable every few days. I'm not versed enough in hardware to know if this is a bad connection between the SD slot and the "motherboard" of the phone. I've seen a number of people have their SD cards go bad with this phone and I assume that means we had a manufacturing issue. It would be really cool if a hardware hacker experiencing this issue could take a look inside and confirm whether or not the hardware is connected correctly.
Well, perhaps there's a high number of bad readers....
I've had the same card in my Q since the day I got it (mid-September), no issues.
Mine wouldn't read the day I swapped up from My Epic 4g Touch to This phone, So I popped in an sd reader backed up my data then let the Moto format it, no issues sence
Curious to know what class of card you guys are running. I've been running a Patriot class 10 but my previous was a class 4 without branding that came with my old Transform.
I'm really hoping that I just had my old SD card die at a bad time and that my newer SD card was just sent bad. Today I couldn't get the card to read from the SD slot in my computer, and it would not be cool if my phone caused it to become that way.

Class 10 Maxell
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2074251
No issues here. I tossed the crappy class 2/4 that shipped with my Epic long ago.
Well I found an extra class 4, 2 GB SD card lying around the house when I was cleaning today. It may be that the local shipment of phones was bad, so if this SD card goes on me then I'll try exchanging the phone in another town just to be safe.
Just out of curiosity does anyone know whether Sprint orders enough phones for replacements with their original shipments? I'm not from a very large town so I'd imagine they would keep replacing with phones from the same batch.
I've got a Samsung 32GB class 10 mSD.
Nearly everytime I reboot my Photon Q it says "SD Card is damaged".
Go into settings, Mount SD Card once or twice and it works.
I've read, that other Android Devices have also problems with that size of SD Cards. (Google)
I had also problem in recovery restoring a backup, the restore process didn't went correctly
(said that everything was fine), had to use my 2GB mSD, which worked nicely and the backup also.
So I think it's an android/kernel issue than a hardware issue.
I have noticed that I get the corrupt sdcard error everytime I try to use the "mass storage" or "media device" setting with Windows.
I use Ubuntu 99% of the time and leave it connected in "camera" mode, have never had that pop up like that...
I usually just use ADB to copy everything anyway so I do not miss the "mass storage" mode at all.
Just had a 16gb class 10 microcenter branded card go belly up on me. Phone just all of a sudden said it was removed and now nothing seems to recognize the thing. The mount option is completely greyed out, and does the same on my note 10.1 if i pop it in there.
When your cards have gone did they completely disappear and refuse to read?

I wonder if it's the c10 cards...
You guys really shouldn't be using high class cards in a phone - there's really no benefit, as phones use SD card's very differently from camcorders or cameras...
On my ooooold phone, anything above Class6 was bad juju. I have always had class4 or lower cards, no fried cards (yet... lol)
kinda what I am feeling too. Not sure what class card I have but it was just a cheap 32gb from wallmart... Only had that error pop up once with this one though, and that was after trying to use usb storage.

Class 10 shouldn't make a difference to a device. The class/speed only comes in to play when transferring data from/to a computer, which will be faster on Class 10 vs Class 4 or 6.

As best as I can tell, thats a negative. Ive been running with a 32GB class 10 since around when the phone was released, and Ive had no issues. Quite surprising on its own, seeing as I abuse the poor thing. True that class 10 arnt useful for the phone specifically, but some shops only carry class 10 cards.
@hfase
I dont seem to have any issues with mass storage, with ~1GB written a day. Im quite curious as to why some people have this issue.

Maybe it's all down to the quality of the actual card itself?
Perhaps the cheaper no-name / off-name brands have a much higher failure rate....?
I'm not really sure, short of actual hardware issues on the device.
AW: Your SD card likely isn't the problem
Well here is my experience:
I am using a new san disk 32GB class10 micro sdcard. It was never format ed/ used before. The q itself formated the disk.
I have had no problems until using the twisted asanti prebuild
Version. Since then I only got problems with the qu saying the sdcard would be corrupt, after reboot. ( I expected some additional wired things, like the currents widget, which I deleted before reboot reappeared). So I would suggest it is an error in un mounting the sdcard before shutdown, which causes this failure.
Since I usually do not reboot the phone expect for flashing new roms, I had no trouble since then.
Hope this might help to further circle the problem, and maybe find a solution for this.

Since CM10 I haven't noticed any SD-Card issues, but I have the feeling, that there are some issues, which aren't detected.
In the last few days my CM10 was acting weird.
1. The gallery (together with the camera app, 2in1 app) disappeared in the App Drawer (was still in /system/app) and didn't appear again after overwriting gallery2.apk again.
2. The Google Weather App had a graphical issue, so I was sure, that there was a flash issue by restoring ASA14 and flashing CM10 (from SD-Card!).
I solved this issue in copying the nandroid backup and CM10 to the phone and flash it from there.
I have tested my SD-Card in my external cardreader, it had no issues in doing so.
My guess is, that the SD-Card needs more power than the Photon Q can give and is losing some read/write commands.

I think This may have hit the nail on the head. I have had a couple cheap discount cards die but they really died. Cant even read in the PC and one even got really hot when plugged in. Got a good branded card from amazon and havent had a problem since.

I've used better Samsung and Sandisk cards and have had this issue. It just randomly wipes all my data and creates the LOST.DIR with it all in there, but file names are all renamed and would takes years to sort through and try to figure out what is what. All my photos, music, etc.. were basically gone then. It didn't matter that the card was a name-brand or not. I've had the issue with several cards.
I constantly have this problem as well, and I've found that mounting the SD card with a reader or in another phone in a Linux environment fixes it for the most part. I think files still get lost, but you get most of what you had back.
I got a 32GB UHS1 card last week and it hasn't had a problem.
Hello guys, I have problem with my 16GB and 8GB MicroSD, it just standard class not class 10. I got weird behaviour, maybe many people facing the same issue with me. My sd card removed unexpectedly even my sensation was idle. There's no heat no heavy usage running. Tried reformating several times but again this problem still there. Tried changing rom from ViperS, CM10.2, CM11 no luck. Also I had already returned to the distributors with the new microsd but again, it happens to me. I don't why when I use 4GB my sensation running fine, no problem at all. This is the Sensation limitation? Maybe people have some advice how to solve this problem. Thank you
anyone?
Never heard of it, I've used 8gb, 16gb,32gb, and 64gb on multiple htc sensations, never had a that problem you describe.
But, it sounds like the pin might be lose?? does the card pull out easily when you pull it? i.e. you don't push it in first to get it out but even in this case, the card should be lodged safely inside the enclosure. Maybe it's bad design on the card? like too thin or something and so the electrical contact keeps shorting out
try googling
Sounds like a bad SD card to me. I'm using a 64GB Sandisk card without any problem.
I found this thread mentioning problems with S-ON might cause this.

I thought it was my bad sdcard too. Because now I've tested sandisk 4Gb class 4 running without any problem. Don't know why with Vgen Sdcard(local brand on my country) I keep facing this problem, both 8Gb and 16Gb. Maybe the vgen sdcard can't survive with high temperature on sensation, since sensation sometimes getting hot. Today I've ordered Sandisk ultra 8Gb class 10 and will check if the problem still exist.
I believe my micro sd card is trashed but I was looking for suggestions on a way to recover it if possible. It is a 64gb Sandisk Ultra Micro sd. I first noticed it as a problem while running CromiX 5.4 rom2sd, every few weeks it would lock up eventually needing to restore a nandroid or totally reflashing. I suspected the card was the problem and have reverted to running internally without any problems for months. I have deleted the partition and recreated multiple times with GParted. Gparted can see the complete card but when I look at it in a windows environment it only sees 27gb. The options to delete volume in the windows environment, disk management tool, are grayed out and formatting accomplishes nothing. Does anyone have any suggestions before I toss it out?

i had same problem i bought sandisk xtreme 64 gb micro sd and locked it self with couple files. i tried everything as a programmer and warezzer but nothing just locked returned to seller and thet give me new one than same problem again returned again for cash this time. Now im using 32 gb lexar on my xperia z1 and 16gb lexar on my tf700 no problem at the momment i searched web about locked sandisk microsds couple thousand microsds broken i assume. so sandisk best but not this 64gbs microsds one . i believe ...sorry for bad english...
sounds weird, I know, but having had all sorts of weird experiences with SD cards and Micro SD cards sanDisk cards included, just wondered, how are you connecting it to your PC?
The reason I ask is that on a fairly new machine running Win7.1 I have found that if i insert the microSD into a USB adaptor it cannot read it or at best can only format to 32gig, but if the card is put into the holder that came with it my machine can see it and format it to its full size
Agreed, I also have a sandisk ultra 64gb microsd card and in order to format it correctly you have to use adapter/card reader that is sdxc compatible. It usually says on the card reader what it is compatible with. If you dont your sdxc card will show as having less storage space
