CAUTION/WARNING: WD Hard Drives and PCI/IDE controller cards!!!


According to some information on another site, which I cannot FULLY interpret, Western Digital Drives can cause corruption of files when installed on PCI/IDE controller cards.

<sect1>The UDMA Blacklist<label id="blacklist">
<p>

The following drives are ``blacklisted''. You should <bf/not/ use UDMA with
these drives as it may cause corruption of data. To avoid this, the driver
should automatically disable DMA for these drives.

<itemize>
<item>Western Digital WDC AC11000H, AC22100H, AC32500H, AC33100H, AC31600H - all versions
<item>Western Digital WDC AC32100H revision 24.09P07
<item>Western Digital WDC AC23200L revision 21.10N21
</itemize>
My setup was working fine with a Seagate HD. I pulled it and installed a WD to copy some data/files, and afterward, I plugged back in my Seagate. My system did NOT see the Seagate, OR the WD when I tried it again. My WD is NOT listed by model number above, so there are apparently other WD's to add to the blacklist.

I did a work-around, by installing the PCI card in another slot.

SOME drives can cause corruption. Don't paint WD with so broad a brush. There are Seagate drives with problems, as well. You should really be looking into the driver source code before you make posts like this. Chance are, the drivers already have them blacklisted.

Well, just in case you're not, I'll pull a bristle or 2 from the brush. Just for you.
