My harddrive appears to have no partition.

Specs: Windows 7, dual core 4gb ram
I was running XP on an old system. One day windows gave me Write delay failure messages in the sys tray. So that day I bought a backup solution and backed up the most precious data first (family photos etc.) I figured I could go back and grab the rest of the data later. I decided to upgrade to a newer system and windows 7. So now I slave the old drive in and when I boot, Windows 7 hangs. If I disconnect the old drive, it boots fine. So to get further with this, I booted into windows 7 and then I connected the sata cable to the old drive. Windows 7 sees the drive as Drive F: and it says its unallocated. I got ahold of testdisk and testdisk reports it as
500Gb / 465 GIB . When I use testdisk to analyze. it does not find any partitions. If I do a deeper seach, it still does not find any partitions. If I try to analyze it by sector, it is really slow. I stopped the prg when it had read 1088 sectors and it reported read failure on all of them I believe. If I only connect the old drive and boot, it hits the XP splash screen and then goes to the Windows did not boot correctly where you can do a Last known good or the various safe mode options. Any option I select from that menu takes me to the XP loading screen for a sec then the whole system reboots. I am hoping I can access this drive and get the remaining data off of it. OH yeah I tried recovery console and chdsk said it had one or more unrecoverable errors. tried fixboot and fixmbr but it said the old boot sector could not be read or that it was corrupted.

Any help is greatly appreciated.

you can download a program like file scavenger or recovermyfiles, there are a few free file recovery programs, then you can in disk manager set your unallocated drive as a new drive, do a quick format, and then your win 7 will treat it as a normal drive.
you can then recover all your files with software.

I'm a little leery to format anything as well as create a new partition.

ok, i understand your concern,
Windows (and other operating systems) uses a hidden index on hard drives, USB drives, and memory cards. Instead of having to search through the entire drive for a file you request, all it has to do is look it up in the index -- a much faster process.

Unfortunately, if the index is damaged, Windows can no longer find your files, even if the files themselves haven't been corrupted.
Similarly, when you format a drive (especially if you use the Quick Format option), Windows erases the hidden index but does not overwrite the existing files until you start saving new data to it. thats why you can very easily use the recovery programs and recover any info, you can use the recovery programs i mentioned or search for free recovery programs, like you see on this link.
