I have a 200 GB WD. A few days ago, Windows reports that it is unreadable. It is a dynamic disk, recognized by BIOS, and if I unplug it and plug it back in while the computer is off, when I reboot the computer, the "Hardware Wizard" pops up saying it found "WD2000etc" but it is not listed in My Computer. Luckily, I have a Knoppix disk that a Linux Apostle recommended I have when the going gets rough and Knoppix will recognize it. I can only copy some stuff off of it to a FAT32 drive. Why not NTFS? Most of it is corrupt.

Why won't Windows report it as readable?

What Operating System?
Does the drive already have a Partition and is it formatted?
If so what file system (NTFS, FAT32) and what size is the Partition?

I have WINXP SP1. It is one partition of 200 GB. It is NTFS and it has had data on it for about a year(around 180 GB).

Is it Windows XP Home or Pro?

I ran WD's Diagnostic tool and it passed it on a quick test and an extended test. It said the test was successful. It recognized the drive as a physical drive but not as a logical drive. I emailed WD tech support and they told me to reformat. Yea, and lose all my data.... Good reply WD tech support!!!

Well sometimes that happens, thats why since the beginning of computers you have always been told to back up your data. There is very little you can do otherwise if you have anoter HD you can boot from you may try some data recovery software but success is not guaranteed and the software isnt cheap either.

Suggest first backup important data, and use dynamic disk converter 3.0 to fix the problem.
