For the purpose of this script I am happy with just write but I will be needing read in the near future. FYI, I can connect 200 usb-storage devices to a dual cpu intel with 4 GB RAM and an extra pci-usb card on the same irq as the internal usb bus. Basically I am uploading content to a couple of hundred mp3/multi media players at the same time and this script is used by other people with less Linux knowledge than I so I'm trying to make the progress bar as accurate as possible. Otherwise there is a significant lag between when the progress bar says it is finished to when the transfer is actually finished. Speed is also a major issue here so I cannot use the sync option as that causes way too much delay compared to async. Can anyone here shed a little more light on how to monitor the disk activity while transferring data?
