Try using Scsi Probe 2.01 a CDEV. This will allow scanning of
all scsi drives, and mounting of drives powered up after the Mac
is turned on. I don't know if this will help your problem at all,
but it is handy to have.It's avaliable on AOL. You could also
try putting you internal into your external case, that would tell
if you have cable or powersupply problems.

I have had a problem similar to this very recently. What happened is that I bought a used Mac II, placed it on its side, installed A LOT of software on the hard disk and tried to run it. What would happen is that the machine will power up, the light for the harddisk would flash for about 10 seconds (it does not stay on, it just falshes.) then I would see the "no startup disk" icon in the middle of the screen. (the disk with an X in the middle.) First I blamed the fact that I had the machine on its side, so after working with the machine for three hours (restarting from a floppy and shutting down) I got the disk to work. I reformatted it in the verticle position as so many people on the net thankfully suggested. That did not do it. The actual problem was that I had DiskExpress II running in the background. I have no idea which of my 15+ INITs it was conflicting with (I personally think it was AfterDark) but it was. I found out that all I needed to do to get the disk to work again when it "disappears" like that is to press the power switch on the back of the machine. This worked at least 10 times in a row without a single failure. Since then I have removed DE II and I have not seen a single problem. Apparently DE II tries to move portions of files together in the background and then it gets interrupted by another process coming back to life. That causes the driver code installed at the begining of the hard disk to be trashed. This is my personal experience, I have no idea what the person with the problem is running. My suggestion to him/her is to check this out before taking the machine apart or playing with the harddisk. Both things can cause a lot of damage if not done very carefully. Sincerely yours, Bassel
