I did the same thing for the first time last spring and actually managed to save everything! Spinning platter, ext4. Here's the process I used, for everyone's future reference. Hopefully it helps, good luck!
First thing I did was boot up a live usb and dd the partition to an image on an external hard drive (good practice to not mess with the original any more than necessary). `dd if=/dev/sda2 of=/mnt/external/mydrive.img` Next I used ext4magic (https://sourceforge.net/projects/ext4magic/ with usage scenarios stuff at http://ext4magic.sourceforge.net/howto_en.html), which is based on ext4undelete but seemed better to me, probably because you can easily recover only files deleted within a certain timeframe, so you don't have a ton of junk dredged up. Example: Files deleted roughly 2 days ago, recovering everything after 3 days ago and before 1 day ago, recovering from the backup image. ext4magic -R -a $(date -d "-3day" +%s) -b $(date -d "-1day" +%s) -d /mnt/external/recovered_files_here/ /mnt/external/mydrive.img Afterwards, I used fslint to search for duplicates and help me figure out which copy of the file to keep. Partly because fslint is really awesome, partly because I was really low on space at this point...
