[Q] Sd issues. a500 not recognizing sd card - Acer Iconia A500

Hi all. I have a stock a500 with 3.1. Not rooted. I put in the 16gb SD card with files in it and I don't get any indication of the card in the bottom right corner. My phone however will recognize it and the files that are on it. Any suggestions? Ty for any replies

"Try unplugging it, and plugging it in again" - Mistabishi 'Printer Jam'.
What FS is the card formatted to? Have you tried any other card that is known to work? Also, try formatting the SD as FAT32 again from the phone.

I am having the SAME issue on my acer. It wont recognize my 16gb sandisk card. I tried formatting as described and I tried another card. Both are showing up in my HTC inspire but nothing on the acer. Whats the deal? When I go to storage in settings- the external SD total space is recognized but it is not allowing me to access it for storage using app2sd?

this SD card worked just fine on the transformer I took it out of.

Are you even able to see the SD card? check /mnt/sd-external to see if it shows up. If it's there, create a directory, then delete it. Also, check the ".android-secure" hidden directory that should be on the SD card after using app2sd. If the permissions are not set correctly, you won't be able to use app2sd with it (reason for create/delete of the directory). Sidenote, I've seen quite a few apps named app2sd, some of them listed are showing up on my end as non-working with the A500 where others listed should work fine.

Still, that does not give me anything to go on. Did you format the card again? Is the card formatted in FAT32? Have you tried formatting the card from your computer using a card reader? I've had SD cards not show up before, reformatting them correctly solved the issue each time. If you don't know what filesystem the card is formatted with, grab a LiveCD with gparted on it (almost any gnome distribution) and I can help you from there. I haven't used Windows since XP SP2 was first released (FCKGW-... if you know what I mean) and I have refused to touch anything Apple since the IIe. Hence the signature.

formatting
Not sure what format they are in. I used a thunderbolt to for mate and a fsscinate and neither were visible. I'll go check what you recommended above though.

What are you guys talking about?
To the OP: You won't have any indication at the bottom. That feature doesn't exist on our devices (but some custom roms based on xoom and ?ASUS? have it). Just check the System screen to see if it finds your sd or simply make a photo from your camera (just set it to save the pictures to your SD). Or use a program and check /mnt/external-sd
To da9b16: a2sd won't work on this device (besides it has enough internal memory).
You'll only be able to access SD directly from your internal memory if you root the device and use a program that creates a symlink from /mnt/external-sd to /sdcard (USB Mount All does this but it's not free) or if you simply navigate to /mnt/external-sd with a file explorer.
I hope that this clears some confusion.

【Urgent】SD card become read only under android

Urgent!!!
I don't know if this is a bug or not. I used to copy files by selecting the disk drive mode. After that I will safely remove the device under windows before disconnecting the usb cable.
The problem is sometimes after copying files to sdcard, the SD card will become read only under android. For example I cannot copy or create files using file explorer. When using camera app it says "Unable to save file to SD card due to insufficient file permissions". When using album it says "SD card unmounted or not present".
After the problem occurs I cannot access the SD card via disk drive mode anymore, unless I physically removed and reinsert back the SD card.
The strange thing is I can still access the SD card in PC via card reader with no problem. I can also view the existing files in the SD card under android (eg opening .apk in SD card)
I tried flashing the ROM for 2 times and with a different SD card. Also I formatted the SD using Panasonic SD formatter and partitioned properly. The problem still appear after several access under disk drive mode. Million thanks!!!
I've noticed the same thing in the DL DesireZ v3.3 nand ROM...
But now since I've switched to skink_Clean_Desire_v1.0 I don't have the problem any more...
No problem solver I know... but just to confirm the issue!
It was also read-only when I had disk drive mode chosen and connected to my win xp pc!
so when I deleted files over the computer they still existed...
I always remove the sd card securely!...
hope this helps a little bit!
Memory cards get weak after awhile...Had d same issue with a Memory card...it works well on WinMo but messes up just as u described in android after a format n a few read & writes...Froyo has also been reported to ruin memory cards...Summary, there's no real solution as i've googled all over....My advice is for you 2 get a new memory card, capacity & class (d higher d number, d better its read & write speed) is up to you...I'm using a class (4) 8GB card n its been alright.
P.S. Stop transferring files via d disk drive option in android..stick to using memory card readers or d MAGDLR function (though some also report file errors with dis).

Thanks for your reply
But how come windows and wm can read and write normally but it doesn't work in android?
Also, I have been using NAND and its disk drive option to transfer file in Cotulla's desire stock Rom and there is no problem at all. Would the problem be related to app2sd since the card has a ext4 partition?
do a chkdsk on your micro-sd card. let it repair and then don't delete the LOST folder in your sd card. ^^ you will be able to mount as read/write after this

Try a chkdsk as well...But in my experience, i did it several times & it only acted as a band-aid...As it reverts to read only ltr on...

So is this a SD card problem or ROM problem?
Previously I had been using Cotulla Desire stock Rom for a month and the problem didn't exist.
I don't mind buying a new SD card if it can completely solve the problem. Thanks

[Q] Help a noob with micro sd problem

I installed a new 32gb class 10 sd. It shows up in Astro file manager as being available. However, none of the many APP2SD programs I have tried allow me to move my apps to the card. What am I missing here? Do I need to format the card first and if so, how do I do that?
Apps2Sd will put apps in the "SdCard" directory which in the Iconia is actual internal memory.
You can only use your card for extra storage (like music/videos)

So, where in the file system is the actual SD card?
It's under /mnt/external_sd
the USB is under /mnt/usb_storage
They will not show up with the USB connector cable attached, but can be accessed through ADB on the host computer.
I think you are meant to actually pull the card and put stuff on it then put it back in the tablet.
Not all media players will see the card because of this name change in Honeycomb.

In the "First start information" document that came with my Acer, it states:
Transferring files from a microSD card (optional) to your PC
Remove the card from the tablet and use a card reader or USB adapter to access the card as an external storage device.

CWM wont show SD card contents...

So I rooted this stupid tablet and put the custom acer recovery app or whatever it is on it. Installed the proper CWM, and when I boot into recovery and try into install zip from SD card all it shows is "Lost.dir". Nothing else. What am I doing wrong?? The ROM/Kernel I want are on the root of my sd card, why isn't it showing up?
Because the tablet isn't stupid it knows exactly where the files should go but you didn't put them there? You just put your files into a wrong directory namely your internal storage.
/sdcard/ = internal storage which isn't used by CWM
/mnt/external_sd/ = SD card which is accessed by CWM
EDIT:
And in case you're looking for USB... The tablet mounts it under /mnt/usb_storage

Some SD cards can not be seen bybrecovery.try formatting your card on another android device or a format utility from your PC.use fat file system.if still no luck try a fifteenth SD card
Goodluck
FAT, FAT32, external sd, usb drive, no matter where I put it, or what i do doesn't show it.

Take your time and have patience. I know the feeling. How are you transferring the data to the micro SD card? Can you use a file manager app to access the card, /mnt/external_sd?
Sent from my HoneyVillain 1.1 HC3.2 using Tapatalk
Again over and over ..try another SD card maybe two this is a very common issue.very common
Try diffrent SD cards if you have not
Or use a USB drive and flash from there. I do it all the time if I'm to lazy to copy the files to my SD card.
I am also stumped with the the acer reading the micro sd card. I am able to see it using root explorer. However, I cant see it when it is connected to my computer. I had to place my sd card in my galaxy tab in order to transfer files to it, and then place it in the iconia. That appeared to be the only way to put the rom on the root of my sd card. I want to save my stock back up to my computer in case I damage my sd card, but there seems to be no way to do it with out removing the card and placing it in another device. Am I missing something? Dont want to start another thread, so I'm asking here because it looks like it's been seen by other users.

FYI ( just in case ) !!!
When fully booted... SD CARD is the internal storage... and the physical card is shown as EXTERNAL SD CARD !
When at CWM recovery... SD CARD is the real physical card !

After using the scan dish program several times I noticed the SD card was not recognized by teamwin recovery every time.
It could have been a fluke but I think.
The MS DOS commands in the OP are more reliable.
I'm using lenovo A7000 and recently updated marshmallow and chosen 32GB SD card as internal memory. It was worked as internal memory perfectly quite some time, all of sudden I got message that SD corrupted and doesn't show data stored in the card, it shows zero files, I lost all media files!! However USB storage option in settings SD card shows 6.5GB used out of 28GB. Since it's treated as internal memory I'm not able to read the card in other devices. I have important media files and documents in SD card and I didn't backup them. I'm bit worried!!! How to recover the data from SD card. I assume if SD card changed back to portable, it will format and lose data!!! Please support

I've heard of this problem before. Good luck
After step 9, is it possible to change it to another format type or does it need to stay on fat32?
Also, does the sdcard need to be connected directly to the pc? When I tried list disk while the sdcard was still in the phone (sdcard>phone>usb>pc), it wouldn't come up.
Had the same thing happen to both mine and my wife's SD cards in the Note 4....I think its the phone screwing things up. When it happen to me the phone rebooted and then the card was corrupt. The are like ticking time bombs..
I use the drive format tool from hiren''s boot usb. 1 click and Works like a charm.

We can just format these corrupted micro sdcards by using the Format SD card in the phone's storage settings? What do you mean by 'dont Use the note 4' though?
I wiped it on my computer, then put it back in once android was started and immediately wiped it, it's worked every time so far.

\t
The note 4 will bootloop with the sdcard you used to root due to the fact it has your bootloader original CID stored on it as a fail safe (something messes up during the procedure ) but any device not using said CID is fine ....I used a Huawei ascend to format .worked fine and formatted card without need of pc.

SD card for app storage

I'm using a 400GB SD card. I saw a comment about creating 2 different partitions on it as I want to use part of it for app storage and the other part for file storage, The second partition would be exFAT so I can remove the card and transfer my books, music, etc. to it by attaching the SD card to my laptop as I understand that Windows would not be able to recognize the partition that would be formatted as internal storage. I did format the SD card using my laptop as two separate partitions. My Samsung Galaxy Tab A saw both partitions. I selected the 96GB partition as I wanted to use that for app storage and selected the option to use it as internal storage. Unfortunately when I did that, it appears that the system set the whole CD card up for internal storage. Does anyone have any insight on how to accomplish this - use part of the SD card for internal storage and part of it for storage that would be recognizable by Windows? Thank you very much.
I have not tried, so take the advice as a suggestion, perhaps android can be "fooled", which I doubt.
After creating a bulk partition in android, move the SD to Windows and resize that partition, and create a second partition on the remaining capacity and hide it.
Now move the SD back to android and see what happens.
If android will reformat the partitions again then I can't advise anything else.
However, if android accepts the memory, then the next step is to discover the partition in Windows and recheck the SD in android.

Well, I was trying to work on that and now the Android Storage module (in Settings) keeps crashing when I open it. IDK what happened here. I've reformatted the SD card, I've removed the SD card, I've rebooted the table multiple times. I'm almost to the point of having to restore the tablet from scratch ... again.

You're trying to convert a partition in sd card as internal storage and leave the rest as an external storage. Not possible as far as I know.

Thats a bummer but that is what I was feeling was going to be the outcome. I guess I'll just go with it as internal storage then and be rlefated to wireless transfer of my books, etc. To the tablet. Any thoughts on why my Storage module keeps crashing now? Something definitely went nuts somewhere along the way here. It was running fine.. until I start poking around with this. I'll probably just do a rebuild again tonight.. if I can find my steps notes.
I also don't think it's possible to do what you have in mind. It's also important to remember that Windows will only mount the first partition of an SD card. It won't see any other partitions without 3rd party software installed.

The reason people want a micro SD card is to be able to move it around between devices, so it is not a good idea to convert it into 'internal storage' for two reasons:
1. You can no longer move the card around (not without reformatting it again).
2. This process would significantly slow down the system if the OS starts saving apps, data and files on the micro SD card because it sees this space as internal storage.
Because of how you partitioned the SD card and tried converting only a part of it as internal storage, my guess is the process caused corruption somewhere, and the system is crashing because of that. I'm afraid you'll have to do a factory reset and start from scratch. I hope your files are safe.

You should NEVER use an SD card for internal storage. They are MUCH to slow for that purpose. Today's SoC have RAM chips mounted directly on top and are several times faster than the fastest SD card bus. And low end tablets, which includes ALL Tab A devices, use a USB bus with limited bandwidth. So using faster SD cards is pointless as they will still only be as fast as the bus. SD cards are fine for storing video, audio, text and downloaded files, but NOT for running apps. Doing so will cause the device to be laggy at best, and cause crashes at worst.

Windows 10 mounts both of these partitions, assigns them letters and you can use them (read and write).

Something strange in that attachment. Since when do Android SD cards have NTFS partitions? As far as I know, the internal storage partitions that Windows couldn't read were formated as Ext3 or Ext4 and the external as either FAT32 or exFAT.

Don't suggest the volume label. Partition K: is FAT. The example shows that Windows can show two partitions on a USB stick.

Of course it can. It can show several. But NOT the two partitions created on an Android SD card because one of then is formated in a file system Windows doesn't recognize and that is what the poster was talking about.
edit: Disk Manager will actually show the partition but it won't be assigned a drive letter because Windows can't mount it.
