Hello there. I'm doing a LiveCD that's based on Knoppix and Linux From Scratch. I was wondering if anyone would have any advice on the following topic:
The LiveCD is to be used by engineering students in a large Windows environment, and the support staff are anxious that writing to hard disks not be permitted. The machines run Win2k, so they use NTFS. Is there a way I might disable write_caching to ide hdds without using the hdparm utility. I am currently looking at ide-disk.c in the /usr/src/linux/drivers/ide directory. I can see where it writes to disk with write_cache and write_flush. Has anyone encopuntered such a problem before? Any suggestions about how I might disable this feature?

Thanks in advance,

Donal
