lost data after trying to install Ubuntu

[Jun Yu]

Hi, there,

Please help!
I have problems need argent help. I lost my DATA.
I installed a 2nd HD before I try to install Ubuntu. I made 4 partitions 
(1NTSF, 3 Fat 32)on it and transfered (from the old HD with winXP on 
it)my data of work to one partition(NTSF) and personal data to 
another(FAT 32). After that, I deleted one partition from the old HD by 
partition magic (it had 3, 1 is made by DELL, 2nd one is NTFS with 
winXP, 3rd one is the one I used to store my DATA, So I deleted the 3rd 
one). Then, I run the Ubuntu 6.06 LTS (BTW, is this the same one as 
Diaper people talking about?) live CD and try to install on the old HD. 
However, it was not successful. I assigned 2 partitions for Ubuntu (one 
ext3, one for wrap). It give me erra when trying to format ext3 
partition I guess.
Anyway, my real problem now is after doing that, I lost my personal data 
on Fat 32 partition, HD2. Do you know is there any way I can get them 
back? It's very very important to me. And, where did i do wrong?
Thanks a lot!
