Hi: Linux does have a scandisk type program, it's called fsck and should run automatically. I'm going to assume you're using an ext2 filesystem. Can't help you if you're not, sorry, though others probably can. I'm also going to assume the fsck failed and it asked you to enter the root password for maintenance. Do this and you'll enter single user mode. Then run fsck manually on the root device that it failed on. It's a good idea to use the -y switch so that it doesn't prompt you for everything, this can be tedious if you don't do this. so if your root FS is /dev/hda1, type: fsck -y /dev/hda1 After it fixes everything, exit single user mode and the machine should go on to boot normally. If this is not what happened, let us know what the error was in as much detail as possible.
