I wanted a fresh install on the system since I was starting to have a strange glitch with Network Manager and started having to manually reconfigure my wireless connection everytime I would go somewhere else. So I popped in the Live CD and selected the option to install. I have 4 partitions on my hard drive, /dev/sda1 (/boot), /dev/sda2 (/), /dev/sda3 (swap), and /dev/sda4 (/home). As usual, I wanted to keep the same partition/mount points setup and just format sda1 and sda2, while keeping sda4 intact. I've done this many times before, but this one time, things went terribly wrong. After the live portion of the install, the system could not boot because a failed mount on /dev/sda4 and then I rebooted live and found that it only sees /dev/sda4 as 1kb in size. Essentially, it would appear as if the installer accidentally marked that partition for resize. Nothing has been written at the end of the drive yet, so data should be fine, but I need some help in figuring out how to tell it the proper end sector for that partition without hurting any data that sits there.

Thanks,

Sorry, I was mistaken /dev/sda4 is the extended partition (that's why it was saying 1kb, but not mounting), /dev/sda5 is /home and it would appear that /dev/sda5 is completely gone from the partition table. I need to add an entry in for start sector 4700, end sector 19457, file system ext3, the data is there already.
