SD Card Removed Unexpectedly when Connected to PC?

I've looked around a bit, and correct me if I'm wrong, but it doesn't seem like anyone else has my problem.
Long story short, I've got a 8GB Class 4 Sandisk SD card, and it worked well for the first few weeks. However, as of recently, anytime I connect to my PC in any way and try to transfer files over using USB or Bluetooth, it fails due to the unexpected removal of my SD Card. This is without me physically removing it of course.
I've tried formatting using default settings, and I don't know what else to try... can anyone shed some light here?

Have you tried another SD?
If you have and problem is still there, I would try a factory reset.
If after all this effort your problem is still not resolved, then i would say a call to HTC is your best solution as it could be hardware related.
Oh couple more things:
Try a different USB cable.
Try a different port or pc.

Okay, I tried it with the stock microSD 2gb, and I didn't get this problem ... basically it just means I've got a bad 8gb?

Be aware there has been countless reports of fake sandisk SD cards being sold everywhere including eBay and Amazon's market place.
So before purchasing a new card Google how to spot a fake sandisk and it should give you an idea of what to look for or not.

I had also faced this situation ...i changed with class 2...nw it working like charm...

I purchased mine from London Drugs, not sure if you know it, but it is a trustworthy place so I doubt my card is fake.
One more thing for clarification, do you think that setting the phone so that it auto installs to SD could have some effect? I set mine up like that due to the lack of internal storage. Thanks for the responses!

i didnt have this issues before hope u can fix it

Auto install to SD should have no effect mate.
Also the fake card situation - well they have been sold by legitimate sellers believing them to be genuine, not trying to deceive customers.
Apparently the market has been flooded with them.
I read about it a couple of months back.
Not saying yours is fake, was just saying your average user wouldn't notice at all.

[Q] Changing SIM without restart

Hi, is there any ways to change sim without reboot on Desire HD.
I'm changing them very often, but restarts are so long.
Any suggestions?

Hot reboot or switch off boot animation and bootsound if they are seperate.
Gotta ask, are you rooted?
Sent from a dream.

Hm.. good suggestions, but I'm recently returned to stock, because I don't have much time to update custom roms. Is there any tricks for stock?

Nope, phone shuts off after it detects a SIM removal.

I am told it can also fry your sim card to do this.

Nope, my SIM still works fine

For now it is. Removing and replacing SIMS while there is power being run to it and info being used not only has a chance of messing up your sim but it could also mess up your sim port, making it not read any sim card so be careful and you should always shut the device down before removing any cards from the device.

Reboot when SIM card inserted
Hi,
I am sorry, this is not really related to this problem, but I have a serious issue with my DHD concerning SIM card. Just yesterday I accidentally left my phone in my car when I went hiking. When I got back after few hours, the phone was really hot, I cooled it down a little bit and tried to turn it on. As soon as I entered my PIN code, phone rebooted. I though it might be because it was still too hot, so I let it sit for a while, then tried it again. Same thing happened. After few tries I found out, that this onle happens, with SIM card inserted and the phone reboots just as it finds reception. Phone works fine without SIM card inserted. I tried factory reset and re-installing currnet ROM. Is there anything I could do to fix this or I have to take the phone to shop.
Thanks for answers

I would try a new sim card before I tried a repair. Sim cards are actually kind of fragile.

I tried two different ones. The other one is definetely fine. It wasn't in a car, I used it in the same phone before and it is two weeks old, so I am afraid it is a phone issue.

Sounds like. Sorry to hear. Could be the sim port.

Sounds like that, hopefully they will be able to do something about it in the shop.

Im sure they can. The thing I never figured out on the DHD, was how to get it apart.

Yeah, hopefully it won't be too expensive. I just asked if someone had the same issue and they fixed through software co I could fix it ASAP. I am on vacation right now, so having no phone is pretty nice, but there are still some situations where you need one.:laugh: Thanks for tips anyway:good:

Are you formatting the card with the phone or in your computer? Have you tried you phone with a different card? Maybe you have a damaged phone, same goes for the card. I got a 64 GB card for my phone, and had to format it with the phone before being able to use it, after that I haven't had any trouble. The only thing is that every time that I connect my phone through USB to my PC (Win7), it tells me the card is damaged and gives me the option of scanning and fixing it or ignore it. I choose ignore, but it a bit annoying to do it every time.

sounds like you have a faulty micro SD card, I had the same problem when I tried to put one into my blackberry. It worked fine on my computer but when I put it into my phone I kept getting errors, eventually it just stopped working all together.

I have a 64gb card and no problem at all. Pop it right in format using phone and just never have any problem with phone or laptop

Your phone came with a memory card?! Mine didn't.
Back on topic, I have had similar issues. I found that is I keep the phone in mass storage mode, and dont allow the internal memory to connect to the computer my issue goes away. I have ICS installed. So long as my internal memory does not connect, my issue has not come back. Give that a shot and see if it works for you as well.

I had this issue once with my OG Dinc. The card just stopped working in the phone but still works fine in the computer to this day. I would bet on your card being faulty.
As for the Ion sd card I feel cheated as mine came with a 4gb card. ?? Got it at Boo Buy also. Lucky for me I had just picked up a 8gb card for another Dinc I acquired.

I too, have the same problem. I have to reformated my card a few times since I got the phone (just about a month). My card is fine, but after using a while, it became unuseable even in my computer. Reformat it, everything's fine but a week later, it came back! I'm on 2.3.7.

Could just be the card. I've had bad ones from the start, had good ones go bad, etc..
I have a generic card that would not work at all unless it was put in to an adapter, and then only sometimes. I've since put it into my Zoom H2 recorder where it seems it's the only place it wants to work full time.
I personally won't buy any off brand SD cards anymore, Sandisk only for me, have yet to have one of these crap out yet.

Make sure you are unmounting the phone in windows before you unplug it. That is what corrupted my card on my incredible.

I see. I'm living in Vietnam, those brand-name cards are so expensive. This card I've used for more than a year with my old Arc, class 10, without any problem. Since it goes with my new Ion, there comes problems! I'm saving money to buy a new card based on your advice! Thank you so much!

Yes, I did it all the time and sometimes I turned off the phone to take the card out for safety. Thank you!

Mine didn't come with sht! wth???
Probably is the card though, I've had similar issues in the past, none with Ion though. Sdcards can be rather fickle and hidden files can get stuck on there much like on a flash drive. I have a box full of flash drives that are irreparable.
Try replacing the card first. Also I usually let Windows repair mine when it asks. Seems to help. eb

[Error] Sdcard unexpectedly removed

This has been the second time getting this error on SG3.
The first time I checked if the card was corrupted by putting the sdcard in the netbook, it was recognized and displayed all the folders. Inserted the card again in the SG3 and it wasn't recognized, rebooted into recovery and fixed permisions and cleared cache/dalvik and rebooted. The card was back up and everything was ok.
Again happened today, tried the same thing and nada Now it also says "Sdcard blank or unregonized file system" in notification and it then prompts for format confirmation upon tapping it.
I've googled and oogled and keep finding different solutions, some I cannot try now since I'm at work. One of them suggest to move all files to PC and format the card, I'll give that a shot at home and see. Another was to update the firmware, but on the latest L13... Apparently, this has been ongoing for sometime and there is an open issue in google for this.
http://code.google.com/p/android/issues/detail?id=19722
http://code.google.com/p/android/issues/detail?id=9736 - Originally opened for LG Ally, but HTC and Samsung users have also reported it on the same issue.
Anyone else encountered this problem in SG3?

Happens to me all the time. Sometimes it will just continue to prepare then unexpectedly removed pops up, then that will cycle and kill my battery. I just got a new SD card hoping that would fix it but it did not.

I'm researching like a mad man! Found a few tools but most are for HDD and not microsd... found the one below that is supposed to detect the card/drive even if it's not mounted or has a drive letter and revover the file system, repair partitions, recover ALL file types, etc but nada
Had a few important fotos, my most recent nanroid, my TB folder, that last one hurt the most.
I didn't back up after the first "fix" cause I thought it was a one time things, never heard of this error before. Lesson learned

If your computer can see it and you don't mind losing data do a low level format on the SDcard
Edit: my SDcard started liked yours but got so bad i couldn't use it at all with my phone, I'm fact Windows couldn't even see it i had to use Linux.

Mine is in that state right now, XP won't pick it up, booting up Win7 PC to try it. My Nikin S70 detects it but it says unusable and won't format it either.
Guess my only option is to partition the netbooks HD and install Ubuntu on it, this gave a good excuse to try it out lol
Found this post that gives some pointers and explains the linux part.

ugggg...... my sd was just totally killed. Windows will not even recognize it now and it reads as a blank SD in the phone. did you figure anything out OP? Mine is 32G sandisk class 10.
this sucks

Same thing happened with me D: did anyone find a solution other than losing all the data on it?
And since I see this thread is fairly new, did everyone else happen to be on the leaked Jelly bean build? It happened to me after the phone rebooted while on the leaked ROM

Apart from the info already here, nope... I need to buy an external sd reader that gets a drive letter assigned without the card and try to force mount on win and run chkdsk, it's the only thing missing. Not even Linux picks it up! Not even force mount! This sucks and seems to have been a problem in android for some time now...
I did order a sandisk 32GB Ultra, but would like to fix this one. Might use it for the camera or give it to my better half for their TF700.

Next time it happens and your pc still happens to pick it up, run a chkdsk on it. Do not format it. It might prevent it from happening again...

i was not on the JB leak. Beginning to think this is a hardware problem, so last night i unrooted and am going to the sprint store today.
I did try force mounting, chkdsk and everything else i could find but nothing worked. fortunately i am still able to return the SD card because i have only had it for a week.

My 64gb class 10 just started doing this after i formatted it to fat32. I am wondering if formatting could be our problem.

Yes and no...It was stated by some members that there was a write-up saying that you shouldn't format your card because this would deduct part of it's useful life.
I never formated my card, it was inserted as soon as I bought the phone and been using it since and never formated it.
I'm going tonight to Wal-Mart and getting a card reader and seeing if that helps in fixing this. In an earlier post I attached a link to an old thread that gives a solution that seems to have helped others.

FYI, just got back from the store and it is definitely failure of the SD card reader. They tested it and my new phone comes tomorrow.

Sprint store? How did they determine it?
I used another sdcard that I had, 8GB, and the phone read it ok...
Edit - then does this mean that there might be a factory reset on the card reader in the SG3? :/

all they told me was that they inserted another card and it happened. Mine also fried two cards so far, so it is definitely pretty bad and i was confident it would fail any test they gave it.

Do you have TEP or was it covered under manufacturer warranty?

i do have TEP but it was covered under manufacturer warranty. took over an hour, but worth having the ability to use an SD card again

Hey guys
Been reading this thread, having the same issue.
Actually the only reason I post because I'm troubled of the error other then having an actual problem, this error been spawning up for me for quite a while, though it does seem to work perfectly fine.
You think the SD card could just Die one day ?
I hope you guys could determine if there's a factory defect in the SG3 or the Card, I got the international GT-i9300, I hope i won't have to return it, since the shop it was bought from is located at Poland and I live in israel (let's say that handling via warranty is not an option).
Need to check perhaps with samsung if they know of any factory defects regarding microSD card readers, My SDcard brand is Sandisk 32GB ultra class 6.

I fixed mine by completely removing the battery and putting in sd card then boot up. Sounds dumb but it worked.

[Q]Sim card removed. Restarting.

Hello,
Yesterday i got this little beast (c1905) and i have a strange problem that i believe it is hardware related.
When i touch the area of the sim card either with the cover on or off the phone tells "Sim card removed. Restarting." and it is rebooting. The sim card fits well and by observing the area i can't see any fault. It is a little annoying when i use the phone in horizontal mode where sometimes unconsciously i put some pressure in that area.
Is this a known issue or mine is problematic? Anyone faced anything similar?
Any idea how i can solve this?
If i don't find anything that can help me i guess i will have to go back to the store and ask them to fix it or replace it...
Rather than that i really like the phone.
P.S. My sim card is new, i had the normal sim so with the phone i replaced my sim card as well.

I am having the same problem.
i thought because i rooted my device that is why it happened..
