I have a problem and need some good ideas from some bright people to resolve it. I rebooted my system from a normal running state by '/etc/shutdown'ing it and then turning off power and then 2 minutes later, rebooting by power on. It did not boot, it just gave me lots of white blocks on the screen. Here are the symptoms and hope someone has a good idea: -- The hard disk will spin up at initial boot time and I can hear the heads relocating themselves. But after the heads are done, the disk spins down and the rest of the machine continues on. I do know that this happens because I can hear it and I also cycle power on it very quickly after it has been "running" for awhile and can hear the disk spinning up from scratch again. -- None of the diagnostics for the hard disk pass. I get "Status = 4". -- I swapped the disk with another one from another 7300 and the system boots fine. -- I accidentally "shorted" a wire that I was testing power on and the disk (NOT THE SYSTEM) began spinning up and it stayed on. However, when running diagnostics, the diags could not read the disk, but it could recal it. -- I had this problem once before, but I just turned the system off over night and rebooted in the morning and the system came up. I tried this again, but a full moon must not have been out because it didn't work. thanks in advanced for any ideas. I am hoping that I don't need a new disk. dale lancaster. fancy signature under construction :-)
