Serious Problem encounted when Backup ROM image !!!!....HELP

After I successfully backup my O2 Mini existing ROM to the SD Card by the romupdate.exe. I used the ntrw.exe to convert the Image in the SD card to my computer. However, when i excute the command
> ntrw read backup.nb1 X:/
it return the followings..
>could not open backup.nb1 -- the volume does not contain a recognized file system. Pleas make sure that all requited file system drivers are loaded and that the colume is not corrupted.
I have tried other card reader (both 1.1 and 2.0) other computer and other SD card ( i am using LEXAR and Kingston 256 ) but the problem exists.
and the romupdate said the d2s command was success.
Why will it happen and
What can i do to fix this problem????
Thanks for your help....

You need to use a card reader and the drive X: should be the drive XP allocates to the SD card slot on your reader.
XP Assigns my SD reader to I: unless you have a lot of network drives on your PC it should be somewhere. The card needs to be in the card reader slot obviously and not the PDA.
I am also assuming that you are trying to write the Rom to your hard drive and not writing it back to the SD?

Hi there, looking at the dos screen you took, its telling you that you have already a file with that name in the folder. look, delete that file... and then try again... i had that problem yesterday. Now im struggling to upload the rom.

by wrong command also, it creates the nb1 file. so do DIR and see that .nb1 with 0 bytes will be there. delete it and try again!

Files on sdhc gone, but storage still taken up?

Hi
I have a problem with my orbit 2.
I connected it via activesync.....and when I went to expolre my windows mobile dased device the folder storage card was COMPLETELY EMPTY !!! omg.......my garmin map is gone all my pics and mp3 etc...
It is wierd, however when i click on properties it says that 1,5GB of 8GB is already taken up?
Any ideas please???

I had the same problem.I think if you hard reset your device and you have encryption enabled you cant see the files on your card but there still there.Windows wouldn't let me format the card so i used Pocket Mechanic http://www.wizcode.com/products/view/pocket_mechanic_professional

but doesn't format erase all the data on the card?what procedure would u suggest to get back the files? btw i don't recall my device recently hard resetting.

It's a common problem on all Windows based OS (including WM).
It caused by Corrupted Filesystem & usually occured on FAT based File System.
FAT based File System (FAT / FAT12, FAT16 & FAT32) is commonly used on Removable Storage including Micro SDHC.
Windows Based OS can cause this Corrupted Clusters / Chained Cluster problem when it failed to close one or many opened files properly.
The failure can occurred due to unstable application (hang) & turning off the device is the only solution.
But,by turning off the device,another problem may occured (Chained / Corrupted Clusters).
Basically almost all of your files are still intact.
To solve the problem :
Turn off your device
Remove your SDHC
Use a SDHC card reader & check for errors using CHKDSK
Press Win+R & when Run dialog box appears type cmd
When Command Prompt window appears type :
chkdsk /f /x <drive_letter>:
Change <drive_letter> with the location of your SDHC.
e.g : chkdsk /f /x f:
I hope this can solve your problem

I agree, I've had the problem with my first WM device (Medion PNA100) and my XDA MiniS and Orbit1 (there was a fix for the Orbit1(Artemis)).
I think it's something to do with write back cacheing and it can happen with other OS's too.
My stepson just trashed an 8GB sandish ultra SDHC by taking it out of the card reader in his PC and putting it back in his Samsung Tocco.
Try CHKDSK and you *might* be lucky, the files are still there it's the FAT that's f*!%$d :x

You can also try more "heavy artillery" approach, using card reader and some of data restoring programs.
They work with HDD's, but most of them works with all R/W magnetic media (floppy, HDD, memory cards).
Here is example of such software: EASEUS Data Recovery Software

Thanks for your advice.......however when i run chkdsk it asks me if i want to convert chains to files?......what should i do?
and should chkdsk give any sort of summary if it found some mistakes?......what is the part of the "report" that i have to pay attention to?

My guess is that only the pics on the card are irreplaceable, if you allow chkdsk to convert lost chains then they will effectively be lost (as pics).
It might be best to try to recover them with data recovery sofware as Bodisson suggests, everything else like the maps presumably you have the originals.

Hi
As chkdsk, didn't do me any good, I used two different data recovery programs. (PC inspector and Zero assumption).....i managed to retrieve most of my pics and video clips.....everything else was unfortunately lost.....I now formatted the card and reinstalled the maps etc.

Everything on the SD card disappeared.. what happened?

Hi,
everything on my SD card disappeared a day ago. It worked when I was on school, but later on the day, I got a notice about the files on my SD card couldn't be read, or it was empty. I've tested it in my pc too, nothing. I haven't formated the card. Anyone know what could have happened to it? can I fix it, or do I have to format it and start over again? (it's not such a big loss, at least now I have learned to backup my memory cards)

tbh, prob best to just format the card and get on with it. Format it in Windows first then also format it on the phone and it should be fine
and yeah, backup in future!

where can I format it in windows, it doesn't show up in my computer when I put it in. Like theres no card in the cardreader. Tried to format on the phone, and download and save a song, but the phone says "no SD card inserted" or something. Is the card broken?

If you put it in an SD card reader (via an adapter, of course) and it's not showing in (My) Computer then it sounds like its goosed

Not at all, must be the partition table which got corrupt. There's a partitioning tool in the administration toolbox in windows but it's pretty basic and i am not sure it will be able to deal with your sdcard. I would recommend Linux and the fdisk shell command, or the gparted program which has a neat GUI. Just fireup your computer with a linux livecd (i suppose even modaco's tiny linux distro should do).
cheers

I don't find any partitioning tool :/ and I have no idea what you mean with fdisk shell command, sorry

Any idea how to format a corrupted sdcard?

I got a class 10 micro sdcard yesterday but when I tried to put music on it the write was like 2M/s. The computer froze in the process so I took the sdcard out before the process was finished. After I restarted my computer the computer wouldn't recognize the card anymore (no show in Computer). It wouldn't be recognized on my phone neither. It did show up on my friend's computer but if I clicked on the disk icon, it asked me to insert a card.....so I guess it might be corrupted because I got it out before the transfer was done.
So is there anyway to format the sdcard (micro sdcard)? I know there are many software that can format the sdcard but they won't work since the computer won't even detect the sdcard....

Wish I knew this as well. I have a corrupted 16GB Micro as well. Trying to format using SDFormatter tells me that it's in read-only mode or some nonsense like that.

Try this first:
http://hddguru.com/software/HDD-LLF-Low-Level-Format-Tool/
Even though windows won't say anything when it's inserted, doesn't mean it wasn't detected, just means windows couldn't mount it. Insert the sdcard and theh download and run the program, selecting the proper drive to wipe.
If that doesn't work u both could try linux. Download any live distro, I recommend slax. Burn it to a CD and boot ur computer from it with the micro sdcard inserted via adapter.
Then use this command with variation to ur specific hardware setup
dd if=/dev/zero of=/dev/???# bs=1M

there is an official tool by the SD Association https://www.sdcard.org/downloads/formatter_3/

You could try right clicking my comupter>manage>storage and look for your card and format it from there may work may not.

SD Formatter has revived many of my cards, it will also re-partition them and format it to a single FAT32 (or FAT if its a small card) partition. All you need is the PC to see the device (such as the card reader) in device manager. Also, if you have a supported card reader (90% don't though) it can do low-level functions such as Flash NAND (of the SD Card) erase.
If it doesn't show up, I would agree to try the /dev/zero method under linux, followed by a SD Formatter wipe once the card is back to appearing in device manager.

Help with 128GB SD card needed

Hello!
My 128 GB SD card (Sandisk) had corrupted files. Every time I delete files, they appear again. I even tried to quick-format the card on Windows, but the files appear again. I also formated it without quick-format which took about 24 hours and the files were again on the card.
Is there a tool that could delete everything? A partition manager maybe?
Is there a way to find logs of what is happening exactly to that SD card? The card is 17 months old.
Thank you!

Run chkdisk on it, it may have errors that need to be fixed.

You should consider formatting SD Card on Android platform rather than Windows.

Ok, but does Android give it a new partition and file format?

Ok, I formatted it from Android within, but there are no changes. All files are still there again.
Is there a write protection on my SD card?

Have you tried running chkdisk on it yet?
If it were write protected, it would prompt you when you went to format it in Windows.

Use this tool in your PC and format sd card in FAT32 format.

@Droidriven: I deleted the partition, but was unable to create a new one. As a result, I was unable to format it again and Windows does not assign any drive letter. Thus, I was unable to use chkdsk. However, Android still recognizes the card, but I cannot make any changes to it. Even when I format it again on Android 7, it says "format succesfull!", but the old data is still there.
@ Ashwinrg: Thank you! But now Windows does not even recognize the card because of the reason I mentioned above.
Update: I manually assigned a drive letter, started CHKDSK, but it says that during "examining the map bits of the volumen" ("el mapa de bit del volumen" in Spanish) errors have been found, but the lost archives cannot be recovered.

To fix the errors
chkdsk X: /f
Where X is the SD assigned letter
To recover some deleted files or files that you couldn't move from SD card you should have used programs like : testdisk or photorec to restore them before you did a format.

@-Hope-: CHKDSK does not work because it throws some error messages.
How do I know if the card lost its abbility to write data? All I can do is read data. I don't want to recover data. I just want to fix the card.

Hello
Seems that the SD is write protected
We can try to disable the protection using diskpart tool in windows
Connect the SD card -via card reader is a recommended step- or if your laptop have a buildin reader
Open a CMD (admin)
Type diskpart then enter
Type list disk then enter
You will see a list of disks and partitions etc..
Type select disk <number of the disk> for example
select disk 2 then enter
Type then
attributes disk clear readonly and enter
Then type exit and enter
The method is explained here with pics on wikihow
http://www.wikihow.com/Disable-Write-Protection
There are some other methods you may try too

Unfortunately, I think after all of this, your card might be too corrupted to repair/reclaim. You might be chasing your own tail with this but I guess it is worth continuing to try.

I already contacted the manufacturer Sandisk which offered me a free RMA. It seems that the SD card is physically broken.
THANK YOU ALL FOR YOUR HELP!
