OK, so it was working fine for awhile, and then while I wasn't using the computer, it is happening again, and the transfer mode on the primary IDE channel has reverted to PIO mode.
I really need some help here to find out what is causing this. So let me tell you some background.
A few weeks ago, I was having trouble with my WD secondary drive, which was a SATA drive attached to a SATA PCI card. It would simply disappear. The drive tested fine, so I suspected the PCI card and/or the cable. So I switched this drive off the card and onto the SATA connector on the motherboard.
In the process, while testing drives, I tested my Seagate primary HD, and HDD Health said its health was only about 48% (although it tested find on all the Seagate diagnostic tests).
So I copied the C: drive on the Seagate (including XP) onto a partition on the WD HD in case the Seagate HD went out, but configured the BIOS so the Seagate is still loading first right now. (I was unable to change to booting from the WD HD because it was missing "ntldr", which I was unable to copy.)
Here are my questions:
1. Are there some sort of drive errors that are causing the primary IDE channel to revert to PIO mode? (It is now the WD that is on this channel.)
2. Is it a problem that there are now 2 operating systems, one on each drive?
3. How do I fix the "ntldr" problem?
4. Should I worry about the Seagate HD going out? What does "48% health" mean since it passed all the diagnostic tests?
5. Could it be the cable to the WD HD?
You guys are lifesavers.
