[Q] SD card - recognized everywhere but android - Android Q&A, Help & Troubleshooting

i have 3 android devices, all rooted. i have a motorola xoom with team rogue's cwm based recovery and CM10. i have an HTC evo shift with TWRP and CM7. finally, i have a motorola photon q with some version of CWM and the stock rom because i don't know how to develop and no one else cares about my phone
none of these devices can see my 8 GB lexar micro sdhc class 6 card. none of them can format them because they dont recognize that the card is even inserted. if i try to mount the card in any recovery, i get some variation of an "unable to mount" error.
the card works FLAWLESSLY in windows. using a usb adapter, i can also see the contents of the sd card (when it contains music) from my car. i can format the f*ck out of it in windows, and i can scan it for errors and always find <= 0 errors on it. i can partition it with minitool and it works great. windows hugs and loves the card because it works and can be formatted and can be recognized and isn't broken. the card has at least once been formatted as ext3 (or 4?). but right now, and previously, it was formatted as fat32.
any ideas?? the card is not shot. and yes, other SD cards work on my android devices, so that rules out a problem with the card slots. what's going on.

i got it sorted out. i grabbed an ubuntu 10 livecd and fired up gparted. initially, i got a bunch of errors about how the filesystem was mounted as readonly. i thought it was because of my microsd to sd adapter being set to "lock". when i pulled it out, it had a lock setting, but it was NOT LOCKED.
so then i grabbed my USB sd card reader and thankfully ubuntu picked it up and i could read the microsd card through the microsd slot. from there, gparted showed me that i had some type of weird partition setup... there was a extended partition and then my fat32 partition was underneath that partition. i never set that up, so i blew it all away and made the entire card purely fat32.
now it works as expected in my devices. minitool and windows both failed me miserably.

New SD Card not recognised-old one fine

I have a G2 Touch w/ Modaco 2.2 ROM and an Ubuntu PC. Previously I had the supplied 2GB SD card partitioned FAT32/EXT2 for A2SD and all was good. My 8GB Transcend sd card arrived today and I created appropriate FAT32 and EXT2 partitions on it. I then copied across the content from the old card to the new one using 'sudo rsync -a' in Ubuntu. I then found that the card was marked us 'damaged' on my G2 and couldn't be accessed there. I tried reformatting and copying to the new card on my PC but same problem, neither partition was visible and my apps did not appear. I tried the phone 'format' facility but this left the card completely unformatted. I even tried swapping the two partitions over so that different ones were first but it was no use. I have had to replace the original SD card which works but now all my applications have lost their system permissions so I have to reinstall >150 apps, aaarggh!
What could be wrong that my 8GB card is seen as 'damaged' and yet cannot be formatted on the phone but it seems fine via the PC? How can I fix it and move my apps and data across and start using it?
Thanks

Cant format my SD-card

I press unmount and then format and i press yes. But nothing happens. It doesnt format and it doesnt remount my sdcard.
Anyone else had this problem?
Im running Modaco (tried on both 2.2 and 2.6)
Yep, I had this problem earlier today. Just bought a new 16Gb sd card, tried to format it and nothing. Nothing on the phone and if I tried to mount it to Windows, it would say mounted, then Windows would say it needs to format the card, but would fail when you try.
In the end, the only thing I could do was to put the card into my work phone (a Touch Pro) and mount it to Windows via that. I was then able to format the card in Windows. Put it back back in the Hero and rebooted (because the SD card error message wouldn't go away). After that, it was fine.
Don't know why it doesn't work, but I think you will need to mount the card in Windows somehow and format it that way.
Plug it via a memory card reader and format it as FAT32 by right-clicking your memory card under "My Computer" and selecting Format..
// This is an alternative method and will most likely work
My 2 yr old 8gig Sandisk SDHC class 2 sudden;u went kaput, cannot be detected by my Topaz (strangely, my Topaz cannot detect other microSD as well, a 4Gb Sandisk Class 6 which is working fine on a Raphael).
The error message on my XP SP3 PC is like this:
Exception Processing Message c0000013
Parameters 75b6bf7c 4 75b6bf7 c 75b6bf7c
[Cancel] [Try Again] [Continue]
Can't detect, thus can't format.
Any help, please?
i'd think that this is connected to apps2sd feature. try partitioning it in recovery image, or format in card reader in pc.

32Gb Class 4 microSDHC - Phone unstable! Please help!

Hi all, I bought yesterday 32Gb Kingston Class 4 microSDHC card. Now my phone is very unstable with this memory. I mean, sometimes it can't mount it, sometimes it shows its empty, formatting almost hangs phone, some apps hang phone (apps on sd). Looks like the phone doesn't want to eat this big memory too well.
I already tried soft reset, and dalvik cache deleting. Didn't help.
microSD is formatted into Fat32 and 32Kb clusters in windows with HP Formatting tool.
If I try to reformat with phone, nothing seems to happen....
It can work perfectly for a 20min, but if I try to turn many apps on and off, it will reboot. After what it doesn't see apps on SD card. wtf? But after complete reboot, it'll work again for a some time.
I have 2.2 Android from elelinux.
If I use my old 2Gb card, everything works just great.
Any ideas?
P.S
What does this recovery mode SD card formatting? Maybe I should try this one?
I have ClockworkMod Recovery 2.5.0.7. There are some interesting options like..
What ARE these?
1. Format Cache
2. Format SD card
3. Format sd-ext
4. Wipe Cache Partition
P.P.S LOL I can't turn off phone. It is rebooting always. Wtf?
32gb SD cards are not supported by the HTC Hero.
16gb max.

According to the HTC website, our Hero's should support 32GB.
But that's as far as my knowledge on your issue goes. Just ordered a 32GB Class 4 SanDisk card myself, so when its delivered (hopefully Friday) I'll let you know how it performs.
Just an update for you, mine came in the post yesterday and it seems to work fine with my phone. Loaded it with 20gb of music and it runs fine.
Yep should run fine with 32gb sd cart
i'm having many of the same issues with my 32gb. had a 16gb before, and all was well.
now the phone randomly goes back to charge only when i have it plugged into PC as disk drive. i'm having trouble making backups in recovery too as it says its randomly unreadable in the middle of backing up. also, and seemingly most frustrating, is it is refusing to actually transfer files from PC to SD. i will plug in as disk drive and move all files without issue. however, when i eject disk drive and switch back to charge only mode (or simply unplug), none of the files have actually been moved to my device. they are simply missing entirely when i open any file manager.
i've tried everything. formatting on device, formatting through W7 (quick and full), and formatting through the official sdcard.org tool. nothing helps.
Try this
If u have a linux PC, u will know about gparted, I guess.
Do this: boot to ur favourite linux distro. plug the sd card to ur pc using a card reader. open gparted. click tools and then click new partition table. it will wipe everything from the card.
once done, just setup the partitions as u want for fat, ext or whatever. i was having a htc tattoo troubling me with a 16GB card but now its okay.

SD works in Nook but Nexus 10 or Windows

I have an interesting problem where I can't see an sd card anywhere but in the Nook Tablet. I recently purchased a Nexus 10 and was going to transfer my 32GB Micro SD card from the Nook Tablet to a USB OTG drive but noticed that it wasn't recognizing the card. So I plugged it into Windows to format it and but Windows didn't find it either. Put it back in the Nook Tablet and the Tablet can see it and if I plug in the tablet I can see the card in Windows again. Take it out and once again acts as if the card cannot be found. I tried to format the card while in the Nook but that didn't help, that just made it unseeable to the Nook till I wiped it with SDFormatter. Now the Nook Tablet can see the card again, but nothing else can again too. I have never seen this before. Is there some special format that I need to do on the card or is it forever stuck as a B&N card? I can't imagine they could lock down the card so much that you couldn't format it, but then again maybe they can (as I can't seem to see it anywhere but in the tablet).
If your PC does not see a "storage drive" when the card is inserted, I'd suggest that you try using Windows Disk Management utility or a Disk Partitioning tools such Easeus or MiniTool to assign a drive-letter to the card after it gets inserted.

I should have mentioned that in the OP, but EASEUS doesn't see it. I used that utility to fix another SD card (by correcting the partitions, was 16GB but only showed 255MB). For this card it's not even showing up to work with at all. It's very frustrating because it's only visible in the tablet. It also doesn't make sense, because I would think that something should show up (in the explorer or the Disk Management). I have tried it on 2 different PC's and a laptop. I haven't tried Mini Tool so I am going to try that next.
Seems to be the SD Card reader

I found the culprit. It seems that the new SD card reader that I got either only reads up to 16GB or doesn't like the type of card I have. Using another reader and it finally shows up. Although that reader is not recognized by the Nexus Media Importer.

Empty MicroSD normally with 64GB now only has 32GB even when empty. (32GB gone)

I have a Sandisk 64Gb MicroSDHC card. I've been using it for sometime on Android and. I've used Android to format it but never to partition it. I've also used Android to wipe data on the card. I've formatted it varous times again on Ubuntu.
The card was working fine but today, I decided to format and clear all the data on it. Much to my dismay, after when plugging in the card and formatting it, Windows read it to have only 27.8 GB space even though it was empty. Ubuntu also showed 27.48 GB only.
I've not much problems with the card on Android and Ubuntu but today, this serious problem occured. Just how does a 64GB card reduce to 27.48GB? I've formatted the card to FAT32 and EXT4 multiple times to no avail with GParted.
Previously, some time ago, I've formatted the card to FAT32 and because the computer, I forgot if it was Windows or Ubuntu and because the computer read it as having 30GB space, named the card 32GB Volume or something like that (The name has long since changed to one of my choosing). However, Ubuntu still read the card as having 64GB of space and filling it up with more than 30GB worked just fine.
What happened? How do I resolve this? I need the card to work on both Ubuntu and Android.
This is my card. http://www.amazon.com/dp/B005V7WIA2 Based on reviews alone, it seems to be very good quality. I've used the card on Ubuntu, and Motorola Defy (Android), and the Motorola Xoom (Also Android). Both Android and Ubuntu have worked with the card just fine except for one thing Occasionally, when copying files to or from the card, I get an error message. Sorry but I don't recall what the message said.
