I would think that a 2nd battery for the bay would be far more useful then replacing it with another hard drive. They're pretty much right on the money that it'd be a pain and a lot of work for very little actual gain since a 2nd HD would also drain the battery faster.

HERE! Use this adapter!
http://cgi.ebay.com/SATA-2nd-Hard-Disk-Drive-HDD-caddy-adapter-HP-tx2000_W0QQ...

I have tested this with a standard 160gb HP drive. And it works! Silently to!!!

One note: you have to loose your DVD drive function because you have to remove the adapter board off the back of your unit.
But you have 2 options:

A: buy this adapter, and then use your old DVD drive as additional USB drive

B: if your anal like me and want a hot swap dvd drive.... Find a broken tx**** drive, call hp "my dvd drive wont work" they will ship you a new one, ship the broken one back. Now you have 2 boards so you can have a working DVD and 2nd hdd bay... also, buy the above mentioned adapter...and you have a 2nd slim dvd drive....

Tx2z-1300 // ZM-87 2.4ghz // 8gb // 1.5tb 7200 rpm// FP + Webcam // N + Blue tooth // 7 Pro//

or you could go crazy.... and put like 1.5 tb of storage in your tx2.....

My original thought for this though is I'm in high school, and I want a redundant back up to the external hdd so if mine fails.... TADA! swap the drives and boom back up and running....

*by external I mean... 2nd

Tx2z-1300 // ZM-87 2.4ghz // 8gb // 1.5tb 7200 rpm// FP + Webcam // N + Blue tooth // 7 Pro//

Now b will only work if you are still under warrenty. And im not quite sure but im 95% sure it just shows up as a seccond drive (not-removeable).

  thank you this is what I was looking for..and I choose option "B" FTW. when you tested this did the drive show as a secondary internal or just another external that you have to 'Safely Remove" prior to disconnecting?

I didn't realize it was so easy to mod yourself. I've got an old TX1000 that I think uses the same bay/interface, and I could sacrifice the board off it's DVD drive and use the weight saver (plus some dremel and glue,) to build up a compactflash reader.

I just bought an older TX2000 drive off Ebay and one of the aforementioned adapters. If anybody else is considering a DIY, it won't be an easy one, as the slimline SATA CD connector is not the same as a standard SATA connector (which 2.5" drives use.) It has a smaller power connector, and is on the extreme edge of the drive, making alignment impossible even if the connector did fit.
The seller of the adapters accepted my offer of $40 btw.

C:..
Sorry, I guess I should have been clearer about DIY. I meant trying to hack something together yourself rather than buy the $40ish ebay adapter. With the board from the DVD drive and the ebay adapter mine works fine as well.
