I seem to be having a problem with the my Western Digital Caviar 6.4GB
UDMA33 (5400RPM?) Hard Drive. I get the following error:
ad0: <WDC WD200BA/P76CA30A> ATA-4 disk at ata0 as master

I do not have any problems with this drive under Windows98, WindowsNT,
FreeBSD3.x or Linux. Never an error reported before.
What does this mean?
I am using the GENERIC kernel from the FreeBSD 4.0-19991215-CURRENT #0: Wed
Dec 15 16:26:48 GMT 1999 snapshot. I have not had time to recompile as of
yet.
I do know that this drive is partitioned funny with ad1s1 as a 2000MB FAT16
partition and the rest as UFS. I saw a warning once that x number of
sectors are not being used because of the off-size of the partitions.
Perhaps I should repartition?
As a side question - why are the CD-ROM (see DMESG below) drives using PIO?
Thanks in advance,
Tom Veldhouse
