I don't know your level of knowledge of Linux, but its best to go over
simple things first. Sometimes it is best to just cut and paste what
you typed on the command line. The reason I came up with my original
question is that I had a customer that didn't realize that the different
mass storage devices kept getting higher scsi device numbers. They were
trying to use the same entry in the fstab file which of course didn't
work. Just verifying that you aren't trying to use /dev/sda when it
doesn't exist anymore and /dev/sdb is where you should be looking.
