I'm trying to build a computer for a friend from spare parts.(Computer A) The Hard Drive was too small, (about 2 Gigs, w/ Win ME) so I added a bigger drive as a slave. The slave drive came from a newer computer and was clearly marked 20GB. (It was corrupted, had to be formatted. The computer I took it from, (Computer B) wouldn't boot, no OS.) Computer A says this is a 2GB drive. I assumed old BIOS/ can't recognize over 2GB. I removed both drives and put them into Computer B, where the 20GB drive came from. (Same config: 2GB master, 20GB slave.) Computer B calls it 2GB too!What's going on? Damaged hard drive? Need to reformat under Computer B BIOS? Will it still hold 20GB despite the smaller label?I'd really appreciate some good advice here.
