[TriLUG] Lost Partition Table!

Hi,

I have recently lost the partition table on my primary disk. My fault. It
has ext2, ReiserFS and LinuxSwap partitions. There are primary and logical
partitions on the disk. Now I'm running from a second disk.

No, I have no copy of the partition table (I had it, but I changed the
aprtitions because I was geting read errors -bad sectors? - so I moved data
around, emptied partiitiosn, created new partitions... and the partition
table was lost in the process.

I've tried gparted and rescuept . So far, no luck. Any other utility around?

gparted doesn't recognize extended partitions. rescuept doesn't work with
ReiserFS.

I just started using TestDisk, but I have no idea of how "good" it is.

Also, with gparted, I do not know how to interpret the results. Maybe is the 
pressure of having
all my data lost. Maybe I'm just another moron. Maybe.

Below you have the result of running both utilities on my system. If you
need more info, please ask.

Any help will be wellcome. Thanks in advance.

The disk:

[root at system home]# dmesg | grep hda
    ide0: BM-DMA at 0xd000-0xd007, BIOS settings: hda:DMA, hdb:DMA
hda: IBM-DTLA-307060, ATA DISK drive
hda: 120103200 sectors (61493 MB) w/1916KiB Cache, CHS=7476/255/63, UDMA(33
)
hda:

It has a max capacity of 60GB. It is (was) not fully used. There should be
something like 20Gb not used in the end of the disk (unpartitioned area).
