Well, I checked the TERM POWR jumper on the disk and it's OK.... the same with the DISABLE PARITY.... everything seems to be alright...
Now... could it be the speed of the HDD? I see that when I try to run a program, it starts loading and after a few seconds it hangs.... HDRATE.PRG says that my HDD has a transfer rate of 1400Kb/s is that too much for a 1040STfm?
