Boot from the USB, but press Escape as soon as it is booted. See if you get a C:\ DOS prompt. If so, try running ReadSpeed by typing "rs.exe" on the command line. That might identify if it is a problem with the application itself, or the splash screen/menu.
Hi @lawson23 : The most likely cause of this is a problem with the creation of the bootable filesystem. Could you try recreating the USB stick, and/or do you have another USB drive that you could try? Thanks!!
@Steve I will give this a shot @AlanD I was able to get dos successfully but upon running rs.exe the first time I got a ReadSpeed two line banner then under it Divide error and a dos prompt again so I kicked off rs.exe again and got the invalid opcode error but it did not scroll like the other execution only two lines of the error.
Going to try rebuilding and see what happens. Thanks everyone
Have you had any other problems with this machine? It looks like the board is a few years old, (DDR2 RAM) I wonder if it is a RAM problem that can cause random crashes. You could try running Memtest86 from https://www.memtest86.com/
Please fetch DrivEnum.exe from https://www.grc.com/dev/SpinRite/ and add it to your USB drive. What is the result if you boot your USB drive, press <Esc>, run DrivEnum.exe, then run rs.exe? If that works what happens when you run rs.exe a second time?
1) What is the result if you boot your USB drive, press <Esc>, then run rs /hashonly ?
2) Go to https://www.grc.com/sr/faq.htm and follow the "How do I make a bootable USB thumb drive??" instructions to make an MS-DOS, not freedos, bootable USB drive. Put rs.exe on it and run it. What happens?
I have an ASRock motherboard very similar to yours running a Phenom CPU. Maybe we have an oddball drive chipset. It has an "Invalid Opcode" the second time I run rs.exe under freedos but not MS-DOS. Running DrivEnum.exe before each rs.exe run prevents the crash. Running rs /hashonly prevents the crash.
I've reported the problem but it hasn't been fixed because it happens on only 1 computer. It will make SpinRite more reliable if it is observed on enough computers to warrant fixing.
First post running DrivEnum.exe works but running RS.exe after produces divide error then if executing it again I get the invalid Opcode - yes running a Phenom CPU
Second post rs /hashonly even when running drivenum before produces divide error then if executing it again it drops a line in dos like it is running but just sits there and left it for like 5 minutes and no changes.
I'm now working on the ms-dos test so will get back to you.
MS-DOS test I can run drivenum. Then I execute rs.exe /hashonly and get "program caused a devide overflow"
if I run rs.exe a second time it just locks up and no invalid opcode error but is locked up.
What happens if you:
1) Under MS-DOS don't run DrivEnum and just run rs (without /hashonly)? Twice?
2) Under MS-DOS run pci.exe?
3) Download RS-49k.EXE from https://www.grc.com/dev/SpinRite/ and run it under MS-DOS? Twice?
