This seems like a stupid problem, but here goes...
I have a Micro SD card plugged in with a USB adapter. I managed to corrupt the filesystem so I've been trying to reformat it (with fat32) without any luck.
First I plug it in an unmount the partition (/dev/sdb1), and I try fdisk'ing it, with:
But apparently I'm not doing domething right:
You will not be able to write the partition table.
I'm guessing that won't work, so I pull open GParted with hope that it will do whatever I forgot to do automatically. No luck:
Unable to open /dev/sdb read-write (Read-only file system). /dev/sdb has been opened read-only.
Can't write to /dev/sdb, because it is opened read-only.
Anyone see where I may have gone wrong?
