Really wanted one of these:
Rapsody S25 OTG for PSPBut for cost reasons, settled for one of these:
Macally On-The-Go PHR-2500TGIt is a little bit pricey compared to the drive I got off eBay for $5.00 plus shipping, but it has a built-in rechargable battery, so it allows you to connect any 2.5 inch hdd to your Zaurus without needing an externally powered USB hub. Just plug it in and mount the drive. To make things even easier, I have followed eji's instructions from here (from 6000 General discussions >> Mounting Usb Dev On Sl6000l in case link breaks):

It has an A/C adapter to charge the battery, and can run for about 2 hours without draining the Z's battery. It comes with a USB cable (mini-B, like the cable that comes with the Z charging dock). If you use the Iriver adapter cable, you can plug it into the Z. Right now, I have an old 6 GB drive (formatted fat32) in it. I plan to install a 40 GB Seagate 5400 rpm drive in it. (This is my spare drive that I use for trying out Linux distros, so I just have to re-format the drive as it has Suse 10.0 on it right now). I will report back results once I install the new drive (probably Monday).
