Saturday:

I don't qu= ite know how, but with fdisk, cfdisk, parted, partx and partprobe I now ha= ve a brand new key with 16 GB (or GiB), the original size, without the iso= file, type vfat (rw, nosuid, nodev, relatime, uid=3D1000, gid=3D10= 00, fmask=3D0022, dmask=3D0022, codepage=3D437, iocharset=3Dascii, shortnam= e=3Dmixed, showexec, utf8,= flush,errors=3Dremount-ro, uhelper=3Dudisks2. I have three oher microSDHC = to save!

Sunday:
That was yesterday! Two of th= e microSDHC cards didn't r= esist to my assaults. But the one with netinst iso (with the two partitions= ) seem to be much harder.

Tired of trying (fdisk cfdisk sfdisk parted= failed with "read only disk"), I put the card in my camera to fo= rmat it, successfully.

On a Mac, it is now known as "NIKON D7= 100" and is read-write, as on the camera. But on my Debian and Fedora = boxes, if it recognized as such also, it stays read only: 'wipefs /dev/sde' continue to read:

off= set =A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0type
--------------------------------------------= =2D-------------------

which was the old situation, mount says &qu= ot;/dev/sde1 on /media/jr/NIKON D7100 type vfat (ro, etc...&= quot; which is correct except for the ro! Same with the other tools.=

How can I force the kernel to forget this '= read only' on the disk? Could it be because of the external card reader I u= se?

It is not really important, since I can use= this card with my mac and to scan documents, but I like to understand.
