The "Bad Target Number" messages are normal. They do not indicate a problem. They show up because a real SCSI bus can support up to 8 or 16 targets, but the USB mass storage protocol allows for only a single target. So when the SCSI core tries to probe for additional targets, those debugging messages get printed. > I also get "Attached scsi removable disk sda at scsi0, channel 0, id 0, lun > 0" in these logs. Still no entry is made in /dev regarding sda. That's because the kernel isn't responsible for creating /dev/sda. You are. Or if you use udev, then udev is. > I need to mount the drive and without this entry in /dev I cannot do so. > > Please let me know how shall I procede. If you're not using udev then you may need to run the MAKEDEV script or something equivalent. Tell it to create the sd[a-z]... device entries.
