Please help me. Software Environment: 1. kernel - linux-2.4.19 + intel_bsp patched. 2. DiskOnChip -- 64Mbytes. We have made the DiskOnChip as a u-disk. Q1. When I use "mkdosfs /dev/tffsa1", WIN2000 And WINXP can read/write the /dev/tffsa1. When I use "mkdosfs -S 4096 /dev/tffsa1", WIN2000 can read/write the /dev/tffsa1, But Winxp can't. Why? W can I make the winxp can read/write the /dev/sda1. Q2. When using "mkdosfs /dev/tffsa1", Our VideoRecord isn't fluent. When using "mkdosfs -S 4096 /dev/tffsa1", Our VideoRecord is fluent. I wonder how the sector size affect the Video Record. Our ultimate goal is 'Video Record is fluent and Win2000/Winxp can read/write the /dev/tffsa1 as a u-disk. Could you anyone give me some good advice?
