Wow  James,
You have a lot of good questions.
The hard drive is the original on a Windows xp home computer.  It is an emachine so it is not a high end computer.
It is the main drive for the computer. I pulled it out and have connected it to one of my win 7 64bit computers via a usb connection. 
It came prepartition off the shelf.

I plan to reuse the hard drive if I can recreate the "C" partition. I am in the middle of getting all images, text files and music off the drive before I attempt to recreate the RAW drive.
I read one fix which said to give the RAW drive a letter then run "chkdsk "X"/f  and that might fix the partitions.  I want to get all the files off the drive first.
I have tried several File recovery programs but the problem is that each program only recovers a selection of files.  What is happening is that program A gets me the first 400 files and program B gets me the
next 300 files. I cannot find a program that will recover all the JPG files at one time.
So I am stuck on what to do next, because I do not want to purchase several File Recovery Programs.
Thanks for you info.
Mike

Mike,  

Some questions:
Have you used SMART on your PC as a first diagnostic tool? 
Is the disk an add on to the PC?
How new is the drive? 
What brand? 
Was it or did it come pre-partitioned, and if yes was the partition used as is or re-partitioned?
Is the partitioning scheme MBR or GPT?
Are you planning on continuing to use the HDD in the M$ PC.?

I have had success with many of the latest Linux live CD's reading HDD's that were questionable or unreadable to M$ systems.  You could download Ubuntu's latest Live CD or create a bootable USB of the image plug it into the M$ PC boot Linux.  Most newest Linux distro's Live CD's will attempt to automount all discovered HDD's and read their partitions.  

Or pull the drive and plug it into one of the Linux Boxes.  If the Linux OS is new enough and has a full Desktop Environment/GUI like Gnome, or KDE etc.  Most likely the disk management system will try to automount the drive and read any existing partitions.  If it comes up immediately copy off / backup any files on the disk to the other native disks on the Linux box.

Good Luck.

James

This has been quite successful for me in the past.

I have a raw hard drive.  It is a windows machine but I also have some Linux Computers. It appears that if you pull the electrical plug from your computer, it could cause your hard drive to lose hard drive partition information.
I am not sure if the same can happen to a Linux computer, so I want to find what is available just in case my files disappear on my Linux machines.
My research has found that some software claims to be able to solve lost file problems on both windows and Linux computers.

I have no idea how good these application are?

Recovering deleted files is also of interest to me.

Thanks

Mike, we need some information to understand the question.  Is this a totally wiped drive, one with some problems, or just deleted files that you are asking about.  Tell us you motivation so people can give valid and appropriate answers (other than restore from your backups).

Does anyone know of software used to recover files in Linux and Winlow systems.
I am looking for software that will work on both operating systems.
Thanks for any help.
