SD cafd read only -

[Dave Ihnat]

Sorry I was buried in work while this thread was playing out--I could have
suggested you just run "fdisk" on it and delete all the partitions.

However, I can add something else here--be careful with SD cards and
capacity.  While building up a bunch of Raspberry Pi 2 Model B 1GB cards
for internet kiosks and slideshow kiosks, I found that "8GB isn't 8GB the
world 'round".  Essentially, even from brand-name manufacturers, an 8GB--or
16, 32, 64, etc.--card from one manufacturer will differ in size.  In my
case, an EMTEC Gold 8GB card was some 200MB smaller than a Kingston 8GB
card.

200MB, you say; no big deal.  EXCEPT all the tools to manipulate SD cards
deal with raw capacity when imaging/copying.  Meaning if the destination
card is even 200MB smaller, you likely end up with a corrupted filesystem.
It should be hit-or-miss, depending on used space, but at least on the RPi
with Raspbian (a Debian fork), it _always_ was broken.

(Because of this, I became too familiar with fdisk, gparted, etc.)

G'luck,
