which software to recover a deleted partition?

Hi everyone and thanks for this useful forum.

I had just installed XP on my system and after installing some software from my external hard drive i realized that something went wrong with the install so i decided to reinstall the os. I forgot to swicht off my external hard drive and when windows loaded all the files and asked me where did i wanted to install xp and all that, both drives appeared, my internal hd and the external with all my data. i was doing something else at the same time and i wasn't paying all the attention i should have so i deleted the partition of my firewire Hd and just after i did it i realized my mistake. The file system for that drive is fat32 and there was only one partition. I did not formatted the ext. drive, i only deleted the partition.

My question is, which software would be the best (fastest, easier to operate, most percentage of data recovered...) to recover my data?

Is it easy enough or should i go to a specialist?

Thanks in advance for your help!!

Once I've lost my windows partition which contains lots of files and documents which were very important to me and my business.

Then I found this brilliant tool to recover deleted partition as well as to recover lost data.. This tool is available at http://www.recoverdatatools.com/partition-recovery.html

Are any of these programs actually free? They seem to only have free trials.

I have used TestDisk to recover partition table on both Linux and WIndows systems;
it is freedomware (GPL) and very easy to use. Highly recommended:

TestDisk is a powerful free data recovery software! It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy.

TestDisk can

Those more familiar with such procedures should find TestDisk a handy tool in performing onsite recovery. "
