SD Card problems from console

Sorry but if this is in the wrong spot but I need assistance. I have searched but haven't found anyone with a similar problem.
I have an 8gb micro sd card, and attempted to format and create the partitions so that I may load the hero rom on my phone. The problem happened as I mistyped something and it gave me warning. I thought I had typed no but it formated it anyway and now only 30mb of the card shows up as raw data. It can't be formated and my g1 doesn't recognize my card (it won't mount). Is it over 4 my card, or is there a way to recover it and get back my normal capacity using console?

you will probably need to get a card reader and use linux to reformat the entire card again, and you may as wel just use linux to format it at that point

I have installed the latest ubuntu & I'm lost. I'm good with computers but never used ubuntu before. I have searched once again but there's no info for what I'm trying to do. The sd card isnt recognized either when I insert it

Try this from terminal and pay particular attention to where the original poster talks about removing partitions.... rm 1, rm 2, etc.

How to recover bricked (locked) SD card by WP7

If you have ruined your Micro SD by installing WP7 over it, here is the solution;
First and the fastest solution is to find a friend with a Nokia symbian phone like N8. Insert the card into the phone, phone says "locked SD" press cancel when it attempts for unclock code. Then use tools menu and select reformat. Get along well with that friend if you ever plan to flash WP7 again.
Second solution is to flash a NAND Android build with working USB storage while keeping the same card in the HD2. When flashing Android recognizes the card and creates a 200 MB partition on it. So this seems to be your card's new capacity. After flashing connect to a PC and select USB storage mode. Now you are done with the HD2, leave it connected in this state.
Windows (Win7 in my case) can see and even quick format the card as USB drive. However you need to low level format with flash erase. Search the forum (or use google) and get the program "SDFormatter V2.9.0.5" of Panasonic. Install it to your PC. When you run it, pick your SD drive, click options, choose Full (Erase ON) in the Format Type and "ON" in the format size adjustment tab. Then click format on the main window. Now you can leave and find something else to kill your time. Depending on the size of your SD this may take a few hours. When it is done, congratulations, you have recovered your SD. Depending on the assigned allocation unit size, Android may not recognize your SD, but your PC surely does. in this case, you need to quick format your SD with Win 7 or another program by choosing default allocation size.
The point here is, if Android recognizes the card, which means it can bypass the "Secure Digital" locking mechanism, then SD is not "secured" anymore and we should be able to format it to the proper capacity in the same way it automatically does for the preset 200MB. I guess lock is somehow removed by MAGLDR (or Android) and we only need to wipe out everything on the SD.

I just reflashed Android(NAND), then reformatted sd card and have 14GB space available. Then saw this post. Will do rest to get all of my SDCard back. Thanks.

SDFormatter v3.0 (BETA)
I had the same problem with WP7 "shrinking" my card. After reading this thread, I searched for SDFormatter and found BETA v3.0. Using that, I was able to just put my card into my PC's card reader and do a format, and got my full 16Gb back.
Just make sure you choose FORMAT TYPE as "FULL" (Erase or OverWrite -- I used "Erase" but I doubt it matters), and most importantly, set FORMAT SIZE ADJUSTMENT to "On."

okay, i've tried using minitools partition to try and delete the 200mb partition and then recreate the entire 16gb that is my microsd as well as sdformatter with full (erase as well as overwrite) with size adjustment on but the problem is that i can only see one partition, the 200mb partition, i can't even see the the second partition or whatever that wp7 created
anyone have any other solutions?

When SDFormatter finished formatting your card, you should have gotten a pop-up giving you the results and listing the size of the card.
On that pop-up, did it say 200MB or had it changed to 14.8GB (which is the usable space on a 16GB card)?

Just simply flash WinMo and use HTC's SD Card format tool in it, works fine (I did it myself that way).

When you format, you format a partition.
WM7 creates 2 partitions, the first one 200Mb and the rest of the SD for the 2nd.
To recover the SD:
1/ delete all partitions (I used EASEUS but many other soft will work, Win7 disk managment will not)
2/ create a new partition
3/ format it.
When I can't recover a disk I use a bootable distri of Linux, it's powerful to manage disks (sorry I've lost my disk so google will be your friend).

Great!
worked but had to do it via card reader on computer. Found SDFormatter V 3.0 and set to full erase and overwrite. Took about an hour but got my memory back! Thanks!

Nokia E51 did the trick
Just to confirm that a humble Nokia E51 was good enough to format an encrypted SDHC 16GB Kingstone Class 4.
After doctor Nokia's cure, I was able to recover all the space, I then used "SD Formatter 3.1" tool in order to totally clean up the card, just in case.
Repeated the trick also against a 16GB SDHC Class 10 Trascend, same great result
HTH

Nothing worked
Tried 5 Nokia phones (no E51 unfortunately), some of them ask for a password even if I say Format or delete the password. Some say that the card is corrupted and refuse to format it. Can anyone advise anything. I have an original SanDisk 16 gb SDHC class 2 card from HD2 T-Mobile. It was locked by WP and I cannot use it anymore.
Any advise will be much appreciated !!

OP's advice doesn't work?
Oh.
I assume that you got rid of it by installing Android. And I assume you haven't got rid of your HD2 yet. If second assumption is wrong, you may go and look for a device that can see the card. If only the first is wrong, skip the next paragraph.
Flash WP7 again. Updating it isn't necessary, but the tool may not work.
Download DEV_STORAGELOCK.cab from here. Send it to your device through WP7 Cab Sender. If you don't have it, download it from here. If you don't know how to use it - put the .cab next to the "WP7 Update Cab Sender.bat" file.
Use it. Double-click that .bat file, exit Zune, wait few seconds and press S. It doesn't work? Install the tool from "if needed install this tool" folder. No need to reboot, just go to that .bat file and press S again. The phone will reboot and the cab will be installed. On the phone tap that key icon, tap OK and ta-dah - the card is unlocked. Turn off WP7, take the card out, use it. Optional - get rid of WP7.

Thank you for your reply. I still have HD2 and it runs Mango just fine. The thing is that 16 gb card was the one that didn't want to work properly with WP. So I bought another one (not one ))) ) Transcend 8gb class 4 and it works fine. So, right now I have one useless 16gb card and I decided to bring it back to life. My only concern, If I switch the cards, will I loose any data on my 8 gig card (I have installed all soft that I need, and I do not want to loose it ), or maybe my phone will start to behave strange? I'm really tired of hard resets and re-installs.
Thank you in advance.
PS
That is why I was trying Nokia "trick"

No, the files should be there. But! WP7 may not boot and tell you that you have to use your 8gb sd. If it doesnt - good, you may unlock it. If it does, then... You will need to hardreset WP7 and that deletes all your files. Or turn it off and go back to your working card and look for devices that may see and format your 16gb.

Thanks, will try what you suggested

good job man..

All of this doesn't seem to work for me. I keep ending up in a boot loop when trying the DEV_STORAGELOCK method. The only WP7 version that i can get to work is XBmod 7004 as the HD2 also ends up in a boot loop when i try to update it. My pc won't recognize my card in any way. And the sad thing is that I only have 1 card with me at the moment. any solutions??

Haven't read the whole thread but Panasonic's SD formatter works a treat if you have access to anything that can mount the SD card to a PC.

anyone here who also had the problem that even SD formatter cannot repair the SD card?

well before formating any way to get the data on the SD card back? 16GB SD card is like 10-15 USD its not a big issue if u lose the card, but the issue actually is in the data that we might loose

If u want to get back your data u can use O&O Disk Recovery. This program restored my files from formatted and locked SD card.

[Q] Creating bootable SD card size issue

Hi all,
It seems that I'm having a bit trouble with writing the image to my SD card. I'm using a 16GB currently with Honeycomb on it, but after the image finished writing, my card size is reduced to 105MB free out of 150MBish. I tried to get the CM7 boot to work on a 2GB card, after the "generic" img finished writing on the card, it gets the same free 105MB, and I can't copy the CM7 files onto the card because those files are 115MB total.
I tried partitioning the card but it's still the same, and the computer isn't able to see the second partition that's not the main one. Is anyone having this issue and/or know how I can fix it? Much appreciated.
Cheers,

Very much a known issue... to work around this:
1. Write the image to SD
2. Resize boot partition (only one on it so far) to anything up to 2 GB.. I recommend keeping it less than 2 GB for compatability
3. Put your ROM on the boot partition
4. Put SD in nook and boot it up

Hey thanks!
So for some reason I was able to follow this post and root my Nook http://www.informationweek.com/byte/howto/231002060
I used the 2GB card again and this time after writing the image to it I still have 1.75ishGB left and the file didn't take up the whole card like it did previously. Was able to boot up CWM and flash CM7.
But I'm running into another problem, which is my 16GB card, no matter how I format it, the Nook would not recognize that it's mounted. And when it does show up in the system, it only sees about 1.5GB, and the card is completely empty. I'm really stuck here, is this another known problem?

What are you using to format it? What format, FAT32? What was on it before? What shows up when in a reader on your PC?

I used EASEUS and also just window to format the card. It's in FAT32 and my PC sees it as a removable storage device just fine, all 14.5GB of it.

LOL
Honestly, the OP does drive me nut
I want to help but I can't follow what he said.
16GB SD, 2GB SD, what?
If you, OP, still need help, then pls clearly indicate what your problem is and what you intend to accomplish.

EASEUS does help a lot (ext4) but I would then suggest never using Windows to format a uSD. This works much better IMO to get a good format.

[Q] Have I Killed My SD Card?

I purchased a new SanDisk 32GB microSDHC card for my Magic a few weeks ago. As of the beginning of this month, I started noticing some strange things happening like the card being set to read-only at random. I first noticed it from the camera app where it stated that I needed to insert an SD card before using it. I checked using Root Explorer, and strangely enough it was mounted as read-only. I mounted it back as R/W, and everything seemed fine...or so I thought.
A few days later, I was gonna send those pics that I took with the camera, but they were gone and nowhere to be found on my SD card. I got suspicious so I took a few test pics after (again) having to set the SD card with R/W permissions using Root Explorer. I checked the card, and the pics were there, but as soon as I tried to send them via MMS, the files disappeared. From here, I put the card in my PC's card reader and copied a random file to it. No issues with that, so I put the card back into my phone and that file was gone. Scratching my head some more, I put the card back into my PC and copied another random file. Then I refreshed the folder view within Explorer, and the file was not there. Seeing that I could read the files on the card, I feel that something strange was going on, so I made a backup to my PC. The files copied fine, and I can see the contents on my computer, so reading from the card isn't an issue. I, then, attempted to reformat it from the computer. Windows complained that it was unable to format the card, so I thought I'd go with something a little more refined when dealing with partitions. Using Paragon Partition Manager, I was unable to reformat without first deleting the partition already present, so I did just that. However, after deleting the partition, it gave an error saying that this drive cannot be formatted. Having gotten really frustrated with this issue, I decided to try out GParted on my laptop. I put the card in my card reader on that and ran GParted. It recognized the card, but showed that it was still partitioned...leaving me to believe that Partition Manager didn't actually delete the partition as it said it did. Didn't worry about that too much, and went ahead and deleted the partition through GParted and reformatted to FAT32 with no errors whatsoever during the process, and everything seemed to work fine. However, the used file space was exactly the same as it was before starting this process. I slapped the card back into my PC, and sure enough nothing has changed.
It now seems that the state of my card is somehow "frozen". I can read the files already existing on the card, but nothing can be written to it. The only thing that I did differently with this SD card, in comparison to any other card I've used, is using Swapper (org.azasoft.free.swapper) to create a swap file on my SD card that appeared to work fairly well until all this happened. Though maybe a 1GB swap file wasn't such a great idea, and most likely unnecessary anyways.
I've had a card die on me in the past, but just because it was old. Though, it was completely unusable...couldn't read or write from/to the card, respectively. So being able to read from the card is quite new to me, and I'm not sure if I've killed it, or if (possibly) there is a chance for revival. Normally, I wouldn't worry about it too much and just have the card replaced, but due to the highly sensitive data currently present on the card, that's completely out of the question at this point.
Any insight on this issue would be very highly appreciated.

I would see if you can get it replaced. If you can't, and their is sensitive info on it, completely destroy it (break it into several pieces, blend it, then use fire) and buy a new one.
Seems like you've done everything I could think of. So I'm not sure what to suggest to try and fix it. Maybe try to dd if=/dev/zero of=/dev/whateveryoursdcardiscalled and then format?
you should really encrypt sensitive data so you don't have to worry about it when problems occur

tl;dr
However, it did seem like an issue I had with an SD card back when I was trying linux distros on USB sticks. My 16GB was turned into an 8GB one. That sucked LOTS. You know what fixed it?
My camera
Yeah, I put the SD on it and pressed Format. It automagically partitioned it and it's working correctly as we speak ... try other devices, such as handycams, cameras, mp4s, iPhone/iPod & such. They can do what Linux + gParted and Windows can't =)

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.

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.
