Thanks for the great information. Now I just need guidance to go the next mile. I have the WD 1001 and the Antec MX-1. I need help marrying the two re. jumper and transfer rate speed. I got some info from the WD site but not enough to make me feel comfortable configuring (jumper) before installing the 1001 in the MX-1. Thanks for some help or direction to go to find help.
I am referring to the 1 TB Caviar Black drive (model WD1001FALS) which is going in the Antec MX-1 enclosure ( russdog recommended both of these in original posting) to use as an external HDD for our DVR.
The WD 1001FALS can come out of the box in either one of two configurations, both of which are set to the 150MB/s speed since they assume that most people are using it for computing. If you want to get the 300MB/s transfer rate for video from this HDD you have to decipher the diagrams on the WD web site.
Mine turned out to be the configuration with no jumper included. The other one comes with a jumper but you still would have to move it to get the faster transfer rate.
If you want to take a look, just go to the WD site and search for the 1 TB Caviar Black drive (model WD1001FALS). You'll see the diagrams there. If you or anyone else can show me where I've taken a wrong turn, I'd appreciate knowing that. I think I got it right though.
That's one of a handful of WD drives that people have reported success with.
Once you sort out the issue with jumpers, let me know and I'll include whatever the story is about that model into the FAQ.
I'm sorry you're running into complications.
It shouldn't be this hard, but it is... at least until we gather enough info among ourselves.
I realize that you just want the dang thing to work, but you've accidentally signed up to be a test pilot.
Hopefully, what you learn can help save others from facing the same kind of confusion.EDIT
Follow-up: Since this post we have learned that the default setting is the correct one, and that there is no need for folks to use jumpers to adjust the out-of-the-box settings. I have updated the FAQ's #6 with a general comment about jumpers. The impetus for that comment was this specific issue with the WD1001FALS. If anybody knows of examples of other modern HDD's where it is necessary to mess around with jumpers, please advise.
Thanks to ronnego, DarinC, and rich584 for their help in sorting this out. (This happened in various posts which they were kind enough to voluntarily delete to help keep this FAQ thread short.)
