I have a Western Digital 200 gb drive that I suspect of being bad, so I wanted to test it. The Seagate drive test didnt help, nor the Maxtor. Obviously, I need a Western Digital drive test.
Google to the rescue; I easily found DOSDLG.exe. But it has to run under Dos.
So I burned it to a CD, and burned Freedos to a CD. I booted from the Freedos CD, and swapped the CDs.
Freedos thought that the Freedos CD was still in place.
Several minutes later, I decided that I wasn't going to be able to change its mind. And I couldn't add the WD diags to that CD, because it was burned as an iso.
So I dug out an old 3 1/2 floppy drive (remember those?) to connect to the test computer, and I found an old bootable Dos disk, and that booted up OK.
But then that didn't recognised the CD drive which had the WD diags on. So I thought, OK, I have to copy the WD Diags to a floppy, but I don't have a working computer with a floppy drive; I stopped using floppies yonks ago. So, I thought, no problem, I'll take a computer apart and add a floppy drive.
This was getting ridiculous. You know the situation where you're trying to solve a small problem, but to do that you have to solve a bigger problem, which entails solving an even bigger problem ...
So I stopped and had a think.
So I formatted a USB drive to FAT-32, and installed Dos on it using Rufus.exe (find it with Google). Then I copied the WD diags program to it. I told the test computer to boot from the USB drive, which it did, and then I was able to run the WD diagnostics program.
