Something about that seems odd to me although I admit that when I've done similar operations I've only ever used "cp -av" from the command line; Never tried it with a GUI file manager copy.
I was using Midnight Commander at the time, which is a text-screen (curses) tool, hence my confusion. I agree completely that using a GUI tool in KNOPPIX would have been a lot slower than the command line.
If I remember correctly [and jump in here people :)] copy operations themselves don't use that much RAM as a buffer because of diminishing returns after the buffer gets beyond 32K/64K.
Well, the system resources were dinky, as the PC was a PII-600Mhz. Perhaps the processor had something to do with it, as KNOPPIX was maintaining that 1.9GB virtual filesystem in the background. Again, command line functions don't have the GUI overhead so I think a CLI interface would have been a lot faster.
Did DMA get enabled on the drives? "hdparm /dev/hda" for example will tell you.
I assume that KNOPPIX's heavy memory use was slowing down the file transfer, and I think I need a CLI-only LiveCD.
Knoppix (at leat 5.0.1) can boot to text-only mode. Its one of the boot options. Its something like "knoppix 2".
Hmmm, didn't realize it had a text-only mode. I'll have to try that out.
