Thank you. I am explaining you what i hv done.
to see the harddisk drive partition in linux.
It show me
first hdd is
/dev/hdb1 1 some no. here SFS
In this drive there was two partitions. I wanted to forrmat this partition by linux. I had written the command:
mkfs -t ext3 /dev/hdb2
It has given me some message that file system changed. When I boot this drive by windows It was changed. But in linux when i used the command fdisk -l, it shows this partition as SFS and I am unable to mount this.
I have again tried to change filesystem by mkfs command, but message was something like 'journal already created'
Please tell where i am wrong.
