Yes Andy, my experience too. Not so much with reformatting in a
phone, but with Windows. Windows reads the read only flags on the SD
and obeys.
Phones, Linux, Media boxes with DVR etc all seem to reformat and
play nicely.
I also use HPUSB-4-WIN.exe in windows which sometimes plays nicely,
and Gnome-disk-utility in Linux to delete partitions and rewrite
them.

I think we have all experienced SD card problems over the years.
Sometimes I find reformatting or recovery tools work, but it's
still a bit
hit and miss if they work.
However I have been discovering that the best way to sort out a
corrupt
SD CARD is actually your cell phone ;-)
I'm no expert but I'm convinced that the reformatters in my
Android phones
appear to be able to write to certain hidden memory areas or reset
hidden
flags somehow.
I guess there might be some collusion between phone makers and sd
card
manufacturers for this stuff, since the industry relies heavily on
the two
working together, and that if there were too many failures then it
would
soon get a bad reputation / bad for business. Well that's my
theory.
When all my other utils fail, I end up shoving the bad sd cards in
my phone
and reformat them in the phone.
So far it's been quite revealing how much more reliable this
method has been.
YMMV.
