Possible to "unpartition" ?

[zorcon]

While installing freebsd onto my server (over an ubuntu install) I neglectied to unplug my Drobo. You know where this is going. having done the freebsd install a number of times, i zoomed though the labeling and paritioning and formating and only after rebooting did i realize that freebsd didn't detect my primary drive, and I had instead formated my ext3 formated drobo. Is there anyway to "rescue" the data that was on the drobo? most of it was legal mp3s and avi's which i don't care about, but it was also my Photo repository. I'd love to be able to rescue the couple of months worth of photos since my last DVD backup burn.

specifics: drive is about a terabyte, usb /dev/sdb
I'm booted back in ubuntu server 8.04.01
the freebsd I was installing was 7.0-Release

svr:~# parted /dev/sdb
GNU Parted 1.7.1
