[Dungeon Lords] Hello, I have a problem...

"Hello, I have a problem...":confused: I understand that I can ask questions here. So, are there people on the forum who really know about hardware? I bought an additional hard drive for my old one. I connected it to the bus, turned on the computer, but the hard drive is not detected.:confused: I tried setting the jumper to both Slave and Master positions, and I tried many different options - but it's all the same... it doesn't work:(. I swapped the ports on the bus - nothing.:( The thing is, I boot into the system, check the devices, and it's there and seems to be working normally; I run a diagnostic - "the device is connected and working properly" - what's going on?:mad: I boot into DOS - the device is listed normally, I boot into Windows - and again, it's not detected.:mad: :mad: I have an old bus. The old hard drive is 40GB, the new one is 160GB. The old one is divided into 3 drives, could that be the reason?:smile07: So, I don't understand what this thing needs to work properly. The old one is already old, and it's about to "go bad":smile17: and "leak":smile15:. Help me if you can:smile45:. Preferably, provide detailed and clear instructions, as if for beginners:smile39:. Thank you in advance!!!:o
