Hi, Say I have mounted a usb disk. I then disconnect the usb device Linux complains about failed writes etc. I then plug the usb device back in Linux still complains about failed writes, and does not recover. How do I get Linux to recognise the reinserted usb disk and carry on as normal? I know my suggested behaviour might be detrimental for some users, in case one modifies the usb disk in another computer and then comes back, but I would like an option that assumes it has not been plugged into anything else. The reason being, I have a system that boots from a USB disk. Due to interference, the USB device disconnects for a second or two and then comes back, but Linux does not see it and I have to reboot Linux to recover. So, in this situation I wish Linux to be able to recover immediately, without needing a reboot. The physical USB device removal then reinserting reproduces the problem I am seeing, so I thought it would be a good example to get working, if we could. Can anyone give me any pointers as to where to start with fixing this? Kind Regards James
