Hello all:

I use suse linux 10.0 default.

My hard drive has damaged.

<snip>

Since the hard drive still has the warranty I would like to
replace it. But before bringing back I'd like to remove some
files from the drive. However I can't write or delete on the
damaged harddisk since it always gets mounted as read-only.

How could I still erase the drive or force mounting the drive as
read-write?

I've had to do this a few times recently myself.

If it is just erasing you want to do, what I did was make sure the drive was
unmounted and then used

dd if=/dev/zero of=/dev/<your_drive> bs=8192

in a terminal, which worked whenever I had to used it.

This may take a while, depending on the size of your hard drive.
I found especially that the block size made a huge difference in speed. I
don't quite understand how to select this value optimally, so the size I used
(bs=8192) was determined from some quick tests writing to smaller files. I
have no idea if this will be the fastest for you or not.
