Readyonly Harddisk Partition

[amiya]

I am using Knoppix Live in a windows installed harddisk. But I fail to copy, create any files or folder in harddisk partition. Can anyone help me ?

Wriiting to a NTFS partition with Knoppix can (and ofter will) corrupt the partition completely. Fat partitions are safe to write to, so on the slim chance that it is not a NTFS partition, post back and I'll try to point you to the assistance you need. But if it is NTFS then find another way to deal with your problem, which is often to use Knoppix to transfer needed data to another computer on a network, then completely reinstall Windows (if you still want Windows) from install discs.
