The next mount would work. One interesting thing. The second mount will work if the media has not changed... mount /fuji umount /fuji mount /fuji will work but mount /fuji umount /fuji mount /fuji hangs. kern.log shows: Oct 13 19:28:31 oscar kernel: usb-uhci.c: interrupt, status 2, frame# 1147 Oct 13 19:28:31 oscar kernel: I/O error: dev 08:01, sector 0 Oct 13 19:28:31 oscar kernel: FAT: unable to read boot sector Oct 13 19:28:31 oscar kernel: VFS: Disk change detected on device sd(8,1) Oct 13 19:28:31 oscar kernel: SCSI device sda: 131072 512-byte hdwr sectors (67 MB) Oct 13 19:28:31 oscar kernel: sda: Write Protect is on Oct 13 19:28:31 oscar kernel: sda: sda1 The device is a usb smartmedia reader using the sddr-09 support.
