Micro SD unformattable? - General Questions and Answers

So the other day I was transferring files between two phones via usb and a windows computer. My micro SD is a SanDisk 32gb. After completion of transferring files from my phone to the other phone, I safely ejected both phones and unplugged the usb cables. On my phone I began browsing through my pictures and within a matter of about 6-8 seconds I literally watched my pictures vanish before my eyes. Leaving only my pictures saved to my phones internal memory and an error message pops up "SD card unexpectedly removed" Odd right? Now the phone won't acknowledge that my micro SD is attached. Took it out and tried using it in a micro SD to full size SD adapter and then plugged into computer. No auto play. And when I select the drive slot for the SD it tells I need to format the disk. Tried quick and regular, both "Windows cannot format the disk" Tried using command prompt to format "Device not recognized...." I can't even format?! What do I do?

how long have you've been using the sd card? lot's of possiblities could happen maybe it's a faulty card - a possible virus infection. have you tried rebooting the pc and insert it again see if it will be detected. or from your device try to reinsert and reboot it.
based on my experience in most cases its a faulty one. i have 3 micro sd which i can't use now.

Recovery Of Missing Files
--------------------------
Your best searching the Internet for a file recovery program. Some may not be able to recover or locate the files that other software will be able to.
The SD Card Issue
------------------
Your best to download partition software, EASUS Partition Home is recommended for this. If you see your SD card simply right click it, and go to delete, and then new and then click 'Apply', and then 'ok'.
If you need any download links hit me up with a pm
hope this helps.

I've had the card for over 2.5 months. And I've added no new data, only transferred data off it(when it crashed) and moved files around. Well it's not my computer. Tried accessing the card on two others besides the one I was originally on. On the computer I last tried, it actually had a built in slot for Micro SD. It says no disk inserted Other Micro SD cards work fine with all computers. I just want to be able to format it so I can use it again but, I'm leaning towards that it might be fried. How it fried itself still doesn't make sense to me

[Q] ACER LIQUID E - 16gb card "checking for errors".....

Hey all.
FIrst off I dont recommend this phone. haha, that being said...
I just bought a 16gb microsd card for it. I was able to install it and transfer a bunch of tunes over. Then when I disconnected it from the computer, it has a little sd card icon with a sprocket at the top left of the screen and says "checking for errors". As a result, I dont have access to the info on the sd card > music contacts photos etc.
Its been 12 hours or so and this status has not changed.
Can anyone shed any light on this issue? Has it "farted" or do I just have to wait...
Thanks.
Have you tryed turning the device off taking the battery and SD card out then putting it all back and turning it back on, had issues with my phone not recognizing my SD before and it worked for me, just give it a try and see.

Thanks, but tried that many times...
I did try removing the battery and card multiple times to no avail.
I even sacrificed my programs etc through a hard reset. As soon as the reset completed, I have the same notification about the sd card.
Some details...
When I first inserted the 16gb SDHC card, the phone acknowledge its presence and I formated the card in the phone. It said there was over 15gb available... all fine...
I then was able to que it up with my pc through the USB cable and transfer about 8 gbs of music to the phone... transfer when fine.
Upon removing the phonne, it started with this "preparing sd card, Checking for errors" nonsense.
I am firmly convinced that there ACTUALLY is no SDHC support on these Acer Liquid E phones. My old 2 gb card that came with the phone works just fine and is back in the phone now. My only other option is to buy a 4 gb card and see if that will word fine, as 4 gb is not considered SDHC. then step up again to a 8 gb card (SDHC) and see what happens.
Does anyone else have a SDHC card in there Acer Liquid E? Does it work?
There is also NO help from Fido or Acer to work through issues...
Really makes me want to go back to the iPhone........ grrrrrrrrr....
Make sure that you formatted it to FAT32 first of all and does the card still connect to the computer using a card reader ? Why don't you try formatting it on your liquid by going onto storage and then unmounting it then format.

Thanks... no go though. At wits end...
Thanks for your attention!
When formatting in the phone, it doesnt allow you the choice to format specifically in FAT32 or other. I can only assume it is formatting in the proper system.
As for mounting and unmounting (what I feel this phone has been literally doing to me for the 6 months i've had it.lol)... as the sd card was stuck in this "checking for errors" sequence I had no access to mount or unmount the card or reformat again. These options were simply greyed out and not accessable.
I have not placed it into a card reader to reformat through my PC. I will try this step next and see what happens. I will have to find a card reader, or perhaps plug it into my camera as the card came with an sd adapter... see if that route will work.
Regardless. extremely user non-friendly phone here in the Acer Liquid E.

[Q]Slow/unstable SD card, fix?

I have 2 Desire phones here. One seems to have a pretty unstable sd card.
I copied the same file to both phones (first over cable, then over wifi). I have made a print screen of the network speed graph. It's clear that the first phone has some trouble with placing the file on the sd card. The 2nd phone only 'glitched' when the phone turned the screen off (near the end).
Is there anything I can do for the first sd card, or should I buy a new one?
Thanks,
Bart.
Scan the card for errors, and see if that works. You can also try to fix bad sectors. If worse comes to worse, format the card.
How would you suggest I scan the card? Android app or windows? Fix bad sectors with chkdsk in windows?
There's probably an app, but the easiest way is to just do it with a PC if you have a card reader or can access the card on your pc via a mass storage option. Right click on the drive (E:, or whatever), then select properties-->tools--->error checking and then scan it for errors. If the card is corrupted, it will be fixed.
Possible fix

Mounting External SD via USB

When I connect to my Windows 7 64 machine, my internal SD shows up so does my external, however the external says insert disk. Is there a solution for this?
Sent from my SAMSUNG-SGH-I727 using XDA App
when you plug your phone into your computer. the prompt comes up on your phones screen are u selecting mount usb storage on your phone?
I have a pre-release version and the build that was on it had some wonky driver or something - the SD card reader didn't work at all and I would get that same message when I plugged it in. A few weeks before the phone went retail they sent out an update that only changed 1 file and BOOM, it works now.
What is your build number?

Try puting outing your micro sd in a sd card adapter and see if your coomputer will read it. Possibly damaged sd card
Had me concerned, followed your suggestion, since I moved directly from captivate into skyrocket. The minute I put in adapter computer read with no issues. Only thing I see is less than 10% available

Either you have done something to the phone or you have a defective unit. When you connect by USB, the connection notification would ask you if you want to connect your internal storage or not. If you choose to do so, then you will bet autoplay for two disks. So, if you install a weird built, you may just want to return to the original condition and move on from there.
The phone itself reads the card, its when I connect to my laptop that the contents of that card do not show up. It says insert drive. Shows drive letter, but thinks there's no media
Sent from my SAMSUNG-SGH-I727 using XDA App
if you use the stock Mount USB, from the status drop down, it should work
if not, then you might want to format your SD card to make it readable
if you use 3rd party Dual Mount or any USB mount widget, you will get the scenario you described in the opening message
Where's my storage??
I am seriously confused. I recently tried to install a 64 GB micro sd in my Skyrocket. When I pout it in the phone said it needed to be formatted. So, I let it format. Then, if I would go to settings it would show a slightly less than 60 GB external storage card was mounted. So when I tried to use file manager or link2sd, I don't see anything that looks like a 60 GB resource. So after much futzing around I removed it and installed a 32 GB microsd. Settings sees it as slightly less than a 30 GB sd card. Again, file manager and link2sd show nothing close to this. In fact, if I go to storage info in link2sd, it says the SD card has a total of 11.25GB, of which 11.2 GB is free. So, how do I straighten this out so I can use the full amount of my micro sd card for storing mp3 content?

Is this class 10? These are common symptoms with SOME manufacturer's of class 10 cards.
In this post, patriot acknowledges minor issues on class 10:

"We have found that there is an industry wide compatibility problem with the new Android based and Windows 7 phones working with 32GB class 10 micro SD cards. We have seen issues with the Samsung Focus, Motorola Driod/X, HTC Evo 4g. We are currently working on a solution for this compatibility issue. Google and Microsoft have stated that there are known compatibility issues with 32GB class 10 micro SD cards and are working on a solution as well.
We have found a fix that works in many cases, where you format the card in a Windows based PC, with FAT32, allocation size 32kb, and full format. This is not an official fix, but troubleshooting steps that has worked in many cases, we are still working on a permanent solution for this issue."
TomTommy, regardless of the date of the post prior to mine, I still have the issue. I see nothing in the thread that resolves my issue, but the thread appears to revolve around a part of my issue. So, here I am. Do you think I might find an answer to my issue in another thread?

2. What he is saying is that thread died that long ago for a reason likely your answers lie somewhere within another thread perhaps Tom is a reputable and generally helpful figure here and really deserves a level of respect but I understand his response seemed harsh

Chappatti, my card is class 6, not class 10. IN any case, I have tried formatting it in a Windows PC to the size it is supposed to be, but the results are the same. The settings measurment of the card shows the right value, but when I try to browse using link2sd or file manager I get the goofy readings.

[Q] sdcard read only

recently i have this situation, my sdcard act like it's being deepfreeze ..
every time i add something, in couple minute, it disappear, and vise versa.
no, im not using adapter that have lock switch, i use card reader instead. and yes it cannot be format with any suggestion tool that i've been search on google. though i have not try to format it on linux.

I've used a few cheapo external SD card readers (USB) that spontaneously disconnected the SD card. Try using an internal one, they're usually higher quality than the ones that come with the SD card.
If you need to completely wipe your SD card try the HP USB Disk Storage Format Tool, it works pretty well in windows.
If that fails, try writing zeros to it in linux.
Exactly what I'm experiencing right now
64gb Sandisk
FAT32
Seriously best described as acting like Deep Freeze..
I've done deletion, modificatio, addition, and after a while, reverts back to it's previous state. As in even the deleted files rose from the dead!!
My attempted fix is just by running CHKDSK /F then /R. So far nothing.
Any luck or any updates?

Problems With Micro SD Card On My Samsung Galaxy Grand Prime Plus Phone

Hello:
I don't understand why My phone does not recognize my Micro SD Card. It has been like that since I bought it four years ago. It didn't work with the SD Card that came with the phone, and even when I bought another one it still didn't work. On the contrary, the card is recognizable by my computer, and when I inserted it in to the phone, using a card reader, it was recognized. But when I put it back in to the SD slot on top of the first SIM slot, it doesn't get recognized.
Please what can be done about this problem. My phone storage is already full. It is just 8GB.
Thanks for your anticipated help.
Can you find the menu item of 'Format' in your 'Settings - Storage - SD card'?

Hello:
I've gone through the article you referred me to. The SD card is recognizable on the computer as I did inform you in that post, so I tried reformatting the card.
But when I visited the link on formatting the SD card, I got this message: You don't have permission to access /EN/Fat32Formatter/ on this server.
So, what else can I do.
How can I find the the menu item of formatting my storage settings of Micro SD card.
Try this
SD Memory Card Formatter for Windows/Mac | SD Association
www.sdcard.org
Hello again:
I've formatted my micro SD card with the link you gave me, but the card is still unrecognizable or undetected by the phone. I remember I did the formatting about a year ago.
I am convinced that the problem is a hard ware one, considering the fact that the card can be detected by another phone and the computer. It was detected on my phone when I inserted it in to a card reader and plugged it in to my phone with the OTG cable. But when I put it back in to the SD card slot, it was not detected.
So, the question now is: what can I do now? how can I increase the storage of my phone. My phone internal storage is now full, and I cannot delete any apps.
What other methods can I try out. Or is there a way of fixing the micro SD slot?
The phone came that way. I didn't care to check the SD card slot before the warranty expired.

have you tried going on your Phone setting and searching for the word "SD"
that would show SD card size and option to format it and such
or perhaps have you tried insert other SD card or SD card socket itself has issue?
Inspect the SD bay contacts. Clean card contacts with isopropyl alcohol/cloth and don't touch them with your fingers.
Make sure it's properly seating in the phone.
Try a hard reboot the phone with the card in it.
Try another card.
Whatever app the device uses for storage control check there to see your options.
In the 10+ it's under Device Care>storage>SD card page 3 dots upper right corner.
If it gives you the option to format it, do so. You will lose any data on the card but it should functional then.
It's best to format the card in the device first before using it.
