I have a 64GB SD card and a Pentax K7 camera. At some point my camera stopped reading the card, and I formatted in camera's settings. Now, I can take pictures and read them on my camera, but my PC does not see it. Disk manager shows it as Disk 1 without any letters assigned. I tried:

  • all of the Disk Manager's possible actions, but it always says 'The system cannot find the file specified'
  • SD Card Formatter that just wouldn't see it.

I don't care about the files, and as I understood from this article. I just want to know if I can format it again for it to be accessible on pc, and if so, how?

When a camera or mobile phone formats an SD card, it uses their own partition layout. Windows can't deal with the format, which is why the disk appears empty or corrupted.

In order to use the SD card in windows again, you have to reinitalize the disk from within Windows.

You should be able to right-click the partition and remove it. Then create a new partition as FAT32 or NTFS and format it. Note that a FAT32 can only be formatted up to 32 gig on windows, but can be formatted to more using a tool. After the partition is created SD Card formatter can probably format it correctly for you.

Alternatively, place the card in your camera, and connect the camera using USB and access the card that way.

Solved by first using Command prompt as it was described here here until the format fs=ntfs label=new quick step.

So,

 diskpart
list disk
select disk 1
attributes disk clear readonly
clean
create partition primary

Then, took the card out, put it in, and formatted in the disk management.

It wasn't letting me to format it directly in the command prompt for some reason, and without re-ejecting I also couldn't do anything with it in the disk manager.
