Solved Can't format or delete files from SD Card

February 11, 2013 at 23:54:52
Specs: Windows 7

Hi;

I've been trying to remove or edit files in my SD Card, when I delete a file I got no errors, I can create files in my SD Card too, but when I unplug it and plug it again, nothing changed, the old files are there and the new ones disappeared... Then I tried to format it, directly in Windows and from the command prompt in windows, I got this error from the command prompt "Invalid Media or Track 0 Bad - Disk Unusable".

I tried with Ubuntu, it said it had formatted the SD card, but again, when I plug it again the files were still there... I've tried with some "low level format tools" with the same result, NOTHING happens... I know many of you would say "just throw it away", but I cannot, it's not mine and I must return it (even damaged) once I remove the data, if you have a way to completely damage the card from my computer (forget the magnet and the microwave) then that would work too...

Please, please, please your help, really, I'm begging you, please... =)

So you've got to return it, ruined or not, and you don't want your data on it.

Did you try Rex's link above?

A low level format ought to do it. What you've tried may just be a zero-fill utility. You might look for something called MAXLLF. It's an old dos based low level format tool from maxtor. If it can recognize the drive it should work, although I have my doubts it will see it. If you do use it make sure you know which drive it's formatting. You don't want to LLF your hard drive.

Other than that, a good static discharge on its contacts may be enough to ruin it. Or put it in a camera and try formatting it using the camera's utility. Or just buy a new one that's exactly the same, scratch it up a little like it's been used and return that one.

Oh, check my # 6 here:

Reconfiguring it so the computer sees it as a regular drive may allow you to format it in the normal manner. I haven't tried the utilities I lnked to there so can't speak for them.

You don't say if it's a mini or micro or standard SD card!
If it's a standard size then it might have a lock slide on the card itself, that would cause the problems you describe.
You could also try https://www.sdcard.org/home/
and download the SD card format from there.

Hello, thank you so much for your response, actually it is a "Syntek USB MSDC USB Device", at least that's the description I see in the properties of the memory... And it doesn't have a lock, it's an internal memory of a device (camera)... Any ideas? Thanks a lot....

If you're trying to delete or add files to a card formatted in a camera or phone you may not be able to do that with a computer. At least I couldn't do that with the micro sd card in my samsung phone. If you're incurring these problems with the card while in the camera, well maybe the card is bad.

I'm not familiar with a 64-bit version of maxllf. If there is something like that it must be because someone reworked it. I'm pretty sure maxtor/seagate doesn't have anything to do with it anymore. True low level formatting hasn't been a user recommended procedure for quite a while..

The problem is dos doesn't recognize USB devices without adding special device drivers. Since maxllf is usually run from a dos bootdisk it's not going to see the card.

Possibly it would run from windows command prompt. I started it with XP command prompt but didn't attempt to LLF anything. And on the maxllf start page it only identified the drives by number.

The more I think about it, the more I think it's not a good idea to use maxllf. I think you'd be better off trying the other things I mentioned. But I have it and can email it if you still want it and can't find a download site.

Oh, another option would be to go into disk management and see if you can remove the partition(s) on the SD card. That would effectively remove all the files.

Thanks a lot Dave, can you please send the file to me? My email address is... Trying to remove the partition from disk management was one of the first things I did and didn't work either... =(

I shall give it a last try with maxllf, and I shall just give up... Do you know if the static discharge can be done from the port to connect it to the USB? Thanks again for your time...

I just sent it. Be careful when trying it out.

You need to click the EDIT button on your post above and remove your email address. That way you'll lessen the chances of getting spammed.

Edit You don't want it connected to a USB port if you're going to try to zap it with static. You might ruin the port. Actually I'm not sure how you'd do it. I've never tried to do something like that on purpose. In a dry climate you could probably set the card on a ground like a water pipe and shuffle your feet on the carpet until you built up a charge and then touch the gold contacts of the card. Ideally the charge would jump from your hand to the contacts, go through the card and then into the ground.
