HD Partitions & Data Lost-Need recovery Help

[RGPHNX]

Hey Guys,
Heres the complete story:
Lost Windows OS due to "sys.ini" file corruption(source unknown). Had to re-install Win ME on primary HD (a Maxtor 10GB) from the "Restore'/Recovery" CD. Had a secondary HD (a WD Caviar 40GB) already installed at the time of the system "restore".

PROBLEM: All partition & file data on the secondary HD (the WD 40GB) seems to be "lost" gone.

QUESTION 1: Is the data really gone or is just the registry & partition data changed due to the "restore"???????????????.

These are the data recovery steps attempted so far:
1) used FDISK to check the partition info on the WD HD>>> no partition info listed.
2) used Western Digital's "Data LifeGuard Diagnostics" program to check >>> no partition info listed.
3) used "PC File Recovery" program to scan the WD HD for data files >>> found 700+ files which it can't read.

QUESTION 2: How can I use KNOPPIX to access/read/write/ & recover the data ???????????
Have Knoppix on disk & it boots up perfectly (many thanks!! ).
Have read "greenfly's" info on using the GPART program but am not sure exactly how to implement/use it (eg. where & when to type the command line info etc.) and/or what other steps are needed to recover data.

Any help appreciated
Thanks in advance

PS- I know this info is here somewhere- have searched >>> "Data recovery" & other terms in the forums >>
gives thousands of posts. Have read for hours but can't narrow this down even with filtered searches. I'm not lazy, just need good sound info help.

Hi Pureone,
Thanks for the link. Read it.
Question: How do I see the data (using Knoppix GUI) in the first place?? So I can save it!! (Have lots of experience in DOS[batch files etc.] but am a total Knoppix noobe.)
Don't know what "sudo fdisk" is. Do I need to use it first ?? & if so how???
I used the standard FDISK program on the Win ME boot disk to view the HD info.
Please advise.

sudo fdisk -l is the command you enter in a console to show infomation about the harddrive.

as for seeing data thats rather easy you just click the icon with a harddrive on it to mount c:\ (hda1 in linux) and you will see all your data.

i will add more details to that text file later on. im guessing i left out too much stuff for most new comers to linux.
