I have a Hewlett-Packard Pavilion #4445 computer, with 4.1GB, 64 RAM. I just installed (I think) a Maxtor DiamondMax 40GB hard drive. I reset the BIOS to make the new drive the master drive, entered its drive information (16383 cylinders, 16 heads, 63 sectors), entered the information about my present 4.1GB hard drive as the primary slave, saved the new settings, exitted and rebooted. When I checked the BIOS, there was no primary slave. Since the computer booted, I'm assuming that the primary master is still the old 4.1GB. Maxtor has a program called MaxBlast that resets the BIOS for you. I downloaded it and tried to transfer the file to a 3.5" floppy. No matter how many disks I tried, I kept getting a "bad sector flag," which aborted the transfer. There seems to something wrong with my A drive: I'm told either that the drive is inaccessible or that the disk in drive A needs to be reformatted. When I try to reformat, I'm told about 3/4 of the way through that it can't be formatted. And my computer freezes. If I reboot with a non-system disk in the A drive, Windows ignores it and boots up as usual. I say I'm not sure if I actually connected the new hard drive because it took me a hour try to make the connections. My fingers are too big, the space is too small to maneuver in and it's hard to get much light into the area.
