Hello, I am trying to byteswap one of my disks. So I parse the next option hdc=swapdata (I also tried hdc=bswap) During boot I see the following message: ide_setup: hdc=bswap cat /proc/ide/hdc/settings bswap 1 0 1 r Looks also ok. But then I do a cp /dev/hdc swappedfile.dat or a dd, but the file is the same as without enabling bswap??? I tried different kernels 2.4.18/7 and 2..2.19 same problem. Do I need to enable an extra option in the kernel? Thanks for reading sofar. Cheers, Erik -- Kernelnewbies: Help each other learn about the Linux kernel.
