In fact it limits the partition to 127Gb, and adds another partition for the rest of the drive. I use this second partition to copy files which I want to keep. Like I always have my demo-reels in my drive with me on a job without taking harddrive space on my laptop.
Focus made a nice piece of equipment!

Can someone post the model of 120G HD they used for this upgrade? I've seen various reports from users using IDE or SATA drives. I'd love to know, specifically, which type this unit uses.

Thanks.

IDE PATA type. I just put a 120Gb Western Digital one in mine.

I used a Segate 100Gb...it only draws 0.48 amps. With the stock battery I recorded for 1hr 45min and then it indicated low battery, I let it go a few more minutes and then decided to power it off so it wouldn't die while I was in recording mode. How much recording time (for battery) did we get before upgrading the hard drive, I wish I did the same test with my original hard drive in. Now I need a battery solution.....
