Hi ! Yes . I understand . I have no choice. I can only instruct the user to wait till the lights go off. I have around 50 different makes of compact flash and usb thumb drives since my work involves lot of embedded systems- mostly headless. I tried with windows - I yank it after the LED stops flickering and give sufficient time after that. The data is written. Please understand there is no way to communicate with the system ! I have no choice - it is an headless embedded system.There is no comfort of keyboard/mouse/monitor ! If I remove the "sync" parameter in Udev rules , it does not work . But when I put back the sync parameter , it writes instantly.I do no know about the kernel stuff so I can only practically try it out and seeing it for myself. The brand did not make any difference but only the "sync" parameter. Actual working is even more complicated . As soon as the USB is inserted it is automatically mounted and then is mounted with fuse /NFS in a remote servers also. As of now it seems to be working well !
