Helloworld.
My symptoms: the device spontanely stopped to detect memory card (the card itself is functioning - checked already, as well as plugging another card into my pola), however the device reacts (wakes up) to the memory card insertion switch status changes (present/absent).
At a glance - all components on the M/B seem to be intact, however I didn't made it yet to unsoldering the card holder and watching inside for bent/absent pins.
Can someone provide me with a clue - what components on the polaris M/B are responsible for communicating with the SD card, and which ones of them I need to check to make sure they function properly?
No clue about that in "classified" service manual from wiki
Am I missing something?
I'm seeing the same thing - curiously problem also occurred on the 6th...
I'd be interested if you find a solution (I'l come back and post if I do)

So, finally got my hands on that one polaris I noticed lying around.
The problem itself was in card-reader slot. I never found the replacement for the slot itself, so I de-soldered it and soldered a micro-sd card right into place using small pieces of old ATA-166 cable lying around. Turned out not as good-looking, as it could be, done by a professional, but still does the job very well. Now device is functioning properly
However, the connector, that was originally on the M/B got 10 pins on the sides, 8 of which supposed to be connected to the micro-sd card. Maybe some1 here know why the hell there is 10 of them and what are 2 extras supposed to be connected to? Also, is the 8 pin supposed to be connected to the switch that represent card absence/presence?
Just before soldering you should try SD Formatter 2.0 for SD/SDHC (sdcard.org/consumers/formatter/) It almost saved my patience !

I dont believe it is possible... but if you REALLY DID IT... then youre really an incredible INSAN3 Genius!!!
PLease give me further details. Since I opened the Polaris to replace a broken LCD screen the SD card reader broke apart... now I'm using my polaris with the (small) internal memory only (sigh!)
...maybe it's right time for a new phone, but while It is still not broken at all... I would like to try to fix the SD in the way you tell us you did it!

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!!
Hi,
I received my new Touch pro and it worked fine for a day, i noticed that it would stop reading the card. i would press the back and the thing would read again. take the card out and put it back in and it would work. then it stopped working all together. No matter what i card i put in it does not read at all.
I put the card into my PC to test and it wont read, i put in another card and it reads fine in the PC but not in the phone..
does anyone know of any utilities that i could use to repair this card.. maybe the FAT table got screwed up.

if your PC read the card, so i think not the card is damaged
i think your diamond pro isnt work well...
no..
I have 2 cards.. a 8 gig and a 1 gig.
the 8 gig worked fine until my diamond pro broke it. it will not read in the phone or the PC. my 1 gig wont read in the phone but works fine in the pc. the card reader in the phone is now dead and the 8 gig is now dead. when i put the 8 gig in the pc it will come up with a drive letter but with a 0 file size and when i click on the drive it tells me to insert disk.
so does anyone know of a program to repair the SDHC?
firstly, thats a Micro SD card, not a SIM card.
Secondly, please could you give more details on make/how old/type of the SD cards trying to be used.
Chances are it was still trying to write when u pulled it out, so it needs formatting.
if you format it make sure it is the right format!

I figured that you noticed after my second post that the subject was wrong..
anyway.. its a 8gig SanDisk about 8 months old. also there was no chance that it was trying to write when i pulled it out. if you look at my first post you will see that the card reader on the phone is damaged and im looking for some type of program to repair the Micro SDHC card...
I am not going to format the card.. I need the information off the card and Ontrack wants 100 to look at the card and 400 to recover the information. This card worked fine with my other pone until i got the diamond with the bad SD card reader.
There's no such thing as a Diamond Pro; only a Diamond or a Pro. As you're talking about removable memory cards I assume you mean the Pro, in which case you're in the wrong forum and you're likely to get more constructive feedback here.
You guys are killing me.. What does that have to do with the fact that I have a bad SDHC card and want to know if there is any application out there that could help me out. If nobody has one to help me then I guess that’s just the case. You guys really get tied up on minute detail rather than the situation on hand. I will edit the subject again, and maybe it will get moved over to the Raphael area..
Thanks for your responses..

Might be a daft question but, have you tried chkdsk?
If that doesn't work how about a/ looking at the card with parted (or similar) in Linux or b/ finding a hex editor that will read the disk 'surface' directly.

Same difference, sounds like Mugglesquop got it right to me!

i will try my linux box in a few minutes..
let me clarify..
i would go to file explorer and it would see the card.. i would try to go to a directory and ht would not see the card and only show my device. i would take the cover off and press on the back, turn the phone over and it would see the storage card again..
so technically if it had a loose connection and while browsing the directories it lost connectivity that could have possibly simulated the removing the card while it was writing issue.
Eh..
Thanks guys.. the linux box could not mount the card.. Ill send it out for recovery.. :-(
Try following the links from this Artemis thread for hints to recover any salvageable data.
I guessed, along with others, early on in this saga that writeback cacheing could be the culprit.
The 'fix' that eventually solved the problem tends to suggest that hardware, (bad contacts etc) wasn't the problem IMO
The end result is the same though, the FAT or mbr gets messed up.
How about fdisk/mbr on your SD (research first though please).
HTH

Funny, I was just searching Google for a fix or repair software for my SDCH card that my Fuze broke and ended up here (my favorite website). I guess is a phone realted issue?
i know this isnt the first of this post. people dont use search anymore. but i had bought an 8gb sandisk card for my fuze when i bought the thing. shortly after the card went all stupid on my like everyone else. i was told by att it wasnt an issue with the phone, it was the sd cards. att replaced it for free, quick and easy, no questions asked. see if you can get it changed out for you where you bought it.
So last night for the second time i get a red triangle notification that tells me my SDcard was unmounted unexpectedly, basically it thought i removed it but obviously i didn't since u can't even reach it with the battery in. I'm assuming its a hardware defect. In order to fix it i have to remove the SD card and reinsert it.
Anybody else have this problem?

Thats a HW defect, if you are rooted, unroot and take it back. They will give you a brand new device.
That's what I'm going to do, only problem is i bent the kickstand and left tool marks when i fixed it
Sent from my ADR6400L
What is the HW defect? This problem of having my sd card unmounting unexpectedly happend only twice, does doing a FAT32 format help? When this would happen to you, was it happening all the time? Thanks, any info will help
Hi all,
Having the same **** here, SDcard was unmounted unexpectedly....
OK.... trying to tell what happened:
I have the phone since Jan 2011 (HTC DHD) I bricked my digitizer and 2 weeks ago I was brave enough to open it to try to replace the digitizer, but gave it up as the display/Digitizer unit was glued....
However, after I put the DHD together again Problems with SD-Card...
By now - I ruled out for myself that it is not software related, as I Wiped the phone fully (formated /data , /system , /cache and so on) and installed a rom, I never had this problem before with - but now I have...
Also I tested with other SD-Card and having the same problem (SD Card Kingston 2 GB and Sandisk Class4 23GB)
So as Said I can rule out the Software and the SDCard itself....
I'll disassemble the phone again to see if there is maybe a loose connector...
If you don't hear from me again this solved my problem
Kind Regards,
Der Matte
OK.... I am Happy to say that I belive that I fixed my issue.....
as stated before, I opened the device and put it together and then I got the error as described above....
Now I just took a few tools and opened it again....
2 things I found wich were not 100%
1: connector to the mainboard was bended a tiny bit but looked correctly seated anyway...
2: very close to the SD-Card reader unit (the slot where you push in the card...) there is a bit of tape... half of it is isolated - half of it is not esolated to get the ground connected to the frame....
I placed the sticker 180 degrees... so the isolated part was not at the right place...
I corrected this - so far all is working again....
So I presume... as I had a Hardware issue in the phone (fair enough caused by myself) all the people having the same symptomps are having a HW problem as well.....
So Now I am optimistic, to get my digitizer replaced too - but this time I will get better tools first
Hope this helps all the other people having these symptoms
If the error comes back, I will update this....
My device HTC DHD

Had the same issue with my S3.
Turned out that the SD card was dying (the card brand is Team Group), this caused it to be unmounted by itself and then mounted again (sometimes showing notification “sd card removed unexpectedly”), hence triggering the “Media” scanning process and significantly draining the battery.
I created an application to monitor how many times the SD card was removed, and turned out to be unmounted every ~3 mins!!!
I then bought a new Transcend 32GB Class 10 card (made in Korea), and until now, this never happens, no reports from the application whatsoever, and no media process eating my battery.
I just published this app in the play store now, this is the link:
https://play.google.com/store/apps/details?id=com.sdcardmonitor
I've been researching this issue and have found a lot of threads about bad/corrupted SD cards randomly unmounting themselves. But the issue my phone seems to have is that the SD card isn't securely seated, and I haven't found much, if any, info on how to fix it.
Basically, my SD card unmounts if I bump my phone the wrong way. More often than not, it happens when I'm putting the battery cover back on. I did some fiddling with it, and once the card is inserted, if I gently pull on the card towards the edge of the phone, it unmounts. If I gently push it back towards the center of the phone, it remounts. I don't think it's an issue with my particular card (SanDisk 32GB Class 4) b/c I've tried two other cards (another SanDisk and an Kingston) and they all do the same thing.
I've tried pushing down on the card slot a bit to try and tighten up the metal sleeve that the card fits into with no luck. I've also tried putting a small piece of tape on top of the card to make it seat more firmly. Neither approach works. If anyone has any suggestions I would greatly appreciate it. I just got the phone recently and have been very happy with it (MUCH better than my old Droid RAZR). But I take a lot of pictures w/ my phone, so having a sketchy SD card is driving me nuts!

Sounds like a hardware problem to me.. If i was in the position i would just get a replacement fone
On my tf300t the sd card slot will no longer hold the sd card in, when you push sd card into the sd card slot there is no "click" followed by the sd card being locked into place, spring seems to work ok as I can shoot the sd card across the room lol. If I hold the sd card in place it will mount ok.
Does anyone know can the entire sd slot be replaced ? Is it a modular thing or solder into the a board ?
If it is replaceable where can I order the replacement part (aside from asus assuming they sell replacement parts) ?
The tablet is about 1.5 years old, sd card slot should last longer very disappointed in quality of tf300t.
Thanks in advance,
Tony

Thanks for the link, I took a look at the Step 2 photo, and it appears the sd card slot is attached to board, and that board can be removed and replaced, appears to be several ribbon connectors.
Now just have to figure out where to get the part.
Thanks

The slot is soldered onto the daughter card which also controls the touchscreen. It can be removed and replaced, but some skills are required. Otherwise, just buy a used one off ebay. Turn the service switch off, or disconnect the battery BEFORE touching anything inside the tab. Otherwise, you risk frying components. After replacing the daughter card, you might have to reflash the firmware to make it work with your current digitizer. Be patient when working on it.
