So I recently tried to put a 4.4 based rom on my cousins boost (d2vmu) s3. I tried cm11,cyanfox and avatar. All ran super smooth except for one issue. I get a "SD card unexpectedly removed" and "Preparing SD card" loop. I tried with two different SD cards (a class 4 PNY 32gb and a class 10 PNY 16gb). I formatted both cards multiple times using a combination of Windows, parted, and recovery and tried fat, fat32,NTFS and exfat and I get the same thing every time. I would normally blame the phone but wouldnt u know it, the stock ROM has no issues with either card. Occasionally I could get the card to mount on boot but most files did not appear when viewing the card with a file manager and eventually would go back to looping the error messages. Philz recovery also had no issues mounting and installing Roms from the card but occasionally hangs during a factory reset when it gets to /storage/sdcard1/.android_secure
I'm not sure what to try from here if anything. He's back on stock for the time being but I'd like to figure this out as its bugging me.
Thanks

This is my first post, and I'm usually pretty careful about following instructions. I'm currently running Skyraider's 3.0 RC2, but to my dismay, I am finding that my phone still refuses to recognize my SD Card. Under settings it says it is unavailable, and when connected to PC, it gives an option to mount to disk but doesn't mount upon selecting this.
My phone is rooted with S-Off and 2.15 radio...Did a full wipe of everything before I flashed 3.0 RC2. Shows that my kernel is now King #2, but I have had this issue with many other roms and kernel combinations. I have been unsuccessful in finding a solution when searching the forums, and the only way to regain functionality is to restore a previous backup without any roms installed.
Any help is much appreciate. Thanks!!!
P.S. I've also tried mounting the card in clockworkmod's advanced recovery settings, but this does not change a thing. Internal storage is also currently unavailable. Mount through usb in recovery does work, but this doesn't help when I cannot access my sd card after boot.
I had a similar issue a couple days ago after upgrading from stock 2.1 to SkyRaider 2.5.2.
When I'd go to set my ringtones, the option for the SD card wasn't there. As if it wasn't reading it was in the phone at all. I opened up Astro file manager to see if it could read it and it in fact did. I could see that all the ringtones were still on the card right where they should be and they would play from Astro when I clicked on them. But, the option to actually set them still wasn't there.
I'm not exactly sure what 'fixed' it, but I went in to set my notification tone and suddenly the option to select from the SD card was there. Then, I could then access the card to set ringers as well. I'm sorry I don't have anything more specific. The card just seemed to suddenly decide to let the OS know it was there. I also rebooted the phone a couple times as well as removing the card while the phone was in use and reinserting it. Not sure if any of that helped the situation or not.
I had asked about this in two separate threads and not one person responded, so I'm guessing the issue is rare.
If you don't get anywhere with it, maybe try a different SD card just to see if it shows up.
Good luck.
I've had the same issue but was able to resolve it. Mount the sd card from a laptop or PC. If you can read the card copy the contents onto the PC (I placed mine in a separate folder). Then go into tools and do an error checking. After replacing the SD card back in the phone see if everything is ok. this fixed my SD card. However, I've had the SD card lose its primary disk notation so I had to reformat and then transfer the previous save files on the SD card from my backup an that solved my other issue. Also, some times the SD card speed can cause this issue and it is perfered that you a class 4 or better. I hope this helps.
Well, I took your advice and pulled the sd card only to mount it separately and scan it for errors. None were found. I've also reformatted and restored all the files that were on it. Phone still does not recognize card or internal storage. My phone did, however, recognize another card I had on hand and I believe it may be a compatibility issue between my 8 Gb A-Data brand Micro SD card and 2.2 roms. FYI...It's a class 6, and the one I tried that was recognized was a 6gb sandisk (class 4). I'll look into getting a 16 or 32 gig sandisk in the near future and keep you posted. Thank you guys for your insight.
always 'safely remove hardware' (stop the device, etc.) from your windows machine before unplugging your incredible
if you don't, you end up not being able to see the SD card until you restart your phone
Just reformatted my SD card, checked for errors after unmounting etc... and now it seems to work ok, although one of the music players I normally use doesn't seem to recognise it!!
Hi...
This is my first post here.
I have a problem with my SD Card.
My SDCard: 32GB microSDHC, some application like music player and gallery sometimes can't read file on my ext sd card (but my file manager can do it flawlessly)
Furthermore, sometimes it shows PREPARING SD CARD on top of the screen, although I don't even do anything. I tried to re-mount it again. But the problem still sometime occurs.
This problem started happening when I changed my stock rom to Ressurection Remix, I thought this problem occurred because of the ROM. so I change it to AOSP. But still... the problem still existed. So then, I changed it back to my stock ROM (with restore option in CWM)
But yeah... Nothing happen.
Any idea?
P.S.: Sorry for my bad english.
extSdCard/sdcard 1 issues
I have a Note II N1907 (ATT) running Liquid Smooth with a SanDisk microSD ultra 32gb. I have been trying to figure this issue out since I bought this phone 2 months ago. I screwed up the original card that I transferred from my old phone some how by trying different things to make the phone recognize it. It worked fine in my HTC Vivid. I have root and am able to use root options to try to access this card of installation, but the best I have been able to do is use it for storage. And I have to manually move things to the card, because most apps do not acknowledge that it is there (can't see it). TWRP recovery can see it after I did my first ROM Flash, but I have to use internal memory for my first ROM Flash, because recovery mode was unable to mount extSdCard.
Is there a kernel I can flash to remedy this. I am no developer, but I think the problem is that the internal memory is also SD in type. I have noticed that internal memory shows up as SDcard0 (zero) and the after market sd card is sdcard1. Maybe the phone automatically defaults to the first sdcard and ignores the other (because it is only designed to have one sd card).
I am sure others have hard this problem with this phone. Thank you for any help you can offer..

As soon as I saw your reply I scanned for the words "Sandisk Ultra" and then I knew this was your issue.
I had a lot of SD card corruption with this brand and searching a lot on the web I found many stories of people having the same issues as I did.
My 32Gb Sandisk Ultra was the cause of many of my problems. 2 months on with a Lexar 32Gb, no problems (touch wood)
Hello, I am on an HTC One V running PACman ROM 15.3, with the kernel JmzPrimoC+.
I started having this problem a couple weeks ago. It would randomly unmount my SD card saying 'SD card unexpectedly removed'.
This started to happen more and more often until it would say that as soon as I put the SD card in.
I did a factory reset, which helped for about 5 minutes before it started happening again. Now, more recently, it started saying 'Damaged SD card. SD card is damaged. Try reformatting it.'
I put it in my computer (which doesn't show anything wrong with it), and did a full format. It didn't help at all.
This problem is happening with both my regularly used SD card (SanDisk Ultra® microSDHC™ UHS-I 32 GB (the red and grey one)), and my ordinary SD card (8 GB class 4 Kingston).
I don't think this can be a hardware problem because when I boot to recovery, TWRP recognizes it perfectly.
But I don't either see how its a software problem, because a factory reset should have helped...
Please help me, any help will be greatly appreciated.
Maybe its a bug in the rom?

Hhmmm...
Good idea. What other ROMs work with JmzPrimoC+ kernel? AOKP?

OK, update, now TWRP won't read the card! Either card!
Now I'm getting really nervous...
Does this mean it must be hardware?
Is there ANYTHING I can do now?
Please help!
Wow, I screwed up really bad.
I was gonna use TWRP to flash a new rom, so I did a factory reset, and then started flashing the rom.
But in middle of flashing the rom it was interrupted. So I rebooted, rereset, and then I realized... it's not reading my card.
I can boot to bootloader and recovery, but that's it. No OS. I'm screwed.
Is there ANYTHING I can do?
Is it possible to flash a rom over USB? Or SOMEHOW get my card working again?
Just enter recovery and use adb sideload to flash a ROM.

But I need an SD card in order to use ADB sideload!
It fails every time because
Code:
E:Unable to mount /sdcard
Is there ANY way to do this without an SD card?
OK, I was able to do it following this guide.
I flashed the latest version of PACman. Still rejecting my SD card though.
I guess it's a hardware issue. Too bad my warranty is void from bootloader unlock :\
Try to partition SD Card in recovery
I am facing same issue and I came across this thread while looking for solution. Here is what I tried. That resolved issue for five minutes and then damn! same issue again but someone can find possible fix using the info here.
HTC One V rooted, currently running MIUI 3.1.2 with JB 4.1.2
Sandisk 8 GB SD Card.
Firmware CWM Recovery
I was facing same issue even before I rooted my phone while Original HTC ICS 4.0 Firmware was installed. MY observation is the problem starts few months after you start using SD Card. (Insert a new SD card in your phone, it will work fine for days / months and then will start giving same error.
While I tried thousand time to remove SD card, clean slot, clean card and reinsert, it did not work. May be worked just once for few seconds. When I tried to connect phone to PC and browse SD card contents, the card was not detected.
Booted to recovery, tried to format card, not detected. Tried to mount SD card, not detected. Then tried to partition SD card in Advanced options in recovery. The available options are 128MB, 256MB, 512MB, 1024MB, 2048MB and 4096MB. Since my SD card is 8 GB, chose the largest option. Now got an option to choose SWAP partition size. Chose 256 MB. Next chose option fix permissions, you have to wait until you see message permissions fixed message on screen.
Now rebooted phone, and voila! It worked!! SD card with 3.94GB memory is detected. But what happened to my rest of 4 GB?
Tried many apps to manage SD card from Play store. Using an app called APart, was able to delete partitions on SD card and create new ones. It worked for few minutes and then again I got SD card unexpectedly removed message.
Does this info makes any sense? I am not a developer and do not know much into phones but someone who know might be able to help. Buying a new SD card is not an option here because its going to work temporarily.
Have you tried formatting the SD card with your computer?

Yes, tried formatting SD Card using computer. Works fine when connected using adapter. Not detected when phone is connected to computer.
So I noticed a very annoying single/double bootloop. When the phone starts, it boots, shows the lockscreen briefly, then goes back to the Samsung logo again and boots again, then finally goes to the lockscreen and functions normally. Sometimes, it loops twice before it finally finishes. 90% of the time, it does just one bootloop per reboot and then works perfectly fine.
Then I noticed it doesn't do this with my SD card removed. It's a 64GB Samsung Pro card formatted into exFAT with about 12,000 files on it.
Then I deleted most of the files from my 64GB card, bringing the number of files down to about 2,000, and it stopped doing the bootloop.
Then I put in a Samsung Pro 32GB FAT32-formatted card, put the same 12,000 files on it, and no bootloop whatsoever.
Anyone else experiencing this bootloop with an exFAT-formatted card? I have a strong hunch Samsung screwed something up in their exFAT implementation or something else that bombs when there are lot of files on the card.
Have you tried formatting the larger card in the phone and then loading it?

Yes, reformatted it several times, both in the phone and on a Windows 7 computer.
It's consistently sensitive to how many files are on it. 12,000 files = bootloop, 2,000 files = no bootloop.
And it only happens if the format is exFAT. It doesn't happen when it's FAT32.
I had this problem before I even fully loaded up my Samsung card. I reformatted and haven't had the problem since. I was having other minor issues at the time that got resolved. I am going back to sandisk next time I need a card.

Format your Sandisk to FAT32 & try it again.
I didn't see this particular fix anywhere else, but it seems to be happening with larger SD cards for many phones, so...
Running: L900 CM11 4.4.4 mid-august nightly w/ stock kernel.
Problem: My SanDisk 64GB SDXC SD card was mounting but showing no data and no absolute file size, with only the option available in tools being the delete all data function (I never tried using it though.)
Kitchen Sink: Tried rebooting, wiping both caches and flashing an older nightly. While a fresh card format seems like the obvious fix, transferring and formatting takes time on such a big card and requires a PC nearby.
The Fix: I booted the phone with the back cover off, and without the SD card inserted. After a full boot to my home screen, I then inserted the offending card and received a notice that it was loading. Saved data was now available with all functionality. After a reboot and battery pull, the card hasn't failed to load since.
I'd be interested in any insight to why this might have worked, it feels like a janky fix at best. A quick search tells you that big SD cards and CM/Android don't always play well.
