Hello, I got a problem with my 1G Sandisk microSD, I can neither write
to the card nor format the card, but I can use the filesin the card.
When i try to format it from windows, it says, format can no t be
finished, not like the write protected thing. And when using HP
formation tool, it can not recognize the card even.

After some study of this thread I try to use dd and PTEDIT32 to fix it
, but not that successful. Firstly after i input "dd --list"
what I got is:

rawwrite dd for windows version 0.5.

the removable media exsits in the first part concering volume things,
but not on the second NT Block Device Objects part. So I can not get
which on is the real object name of this removable media h. Then I
try to use the volume link directly
\\?\Device\Harddisk1\SP0
to point the MicroSD card. and use the command
[code:1:fda6f2ad16]dd if=/dev/zero of=\\?\Device\Harddisk1\SP0 bs=512
count=10000[/code:1:fda6f2ad16] to erase part of the card, but after
it finished with
[code:1:fda6f2ad16]
1000+0 records in
1000+0 records out
[/code:1:fda6f2ad16]
I find no change has been made to the micorSD, at least I can still
use the files in it, and can not format the card still.

Now, how can I do to fix this card now, please to so kind to give a
help, thanks.
