You could try partition manager

When you say try to convert, you mean reformat from fat32 to NTFS? Depending on the size you may not be able to write it as a NTFS. Also, if you have anything on it you want to save, you need a raw recovery tool Squidoo has a good one.
However, if it won't let you format to anything and keeps reverting to raw, most likley your drive is damaged beyond normal repair.

There are two options for you to get your drive stuffs back right now:
1). Do not format this RAW file system external hard drive temporarily and plunge it to your PC. And then, choose and apply RAW external hard drive data recovery software to scan this drive and find your preferred drive files back as many as possible.
2). Directly consult some professional data recovery services from some data recovery companies or agencies.
In the future, remember to save copies of everything important on at least two devices in case of any similar data loss issues.

Install the drive on a working computer and access through disc management. that will allow you to initialize the drive and format it ntfs. Goto my computer right click select manage select drive management. This works on XP if you have other OS than search for disc management for your OS.

Your data is already gone. The drive is raw. No partition no format.
here is a link to a free data recovery program, this probably wont work but may be worth a try

just be sure to opt out of all garbage they want to infest your computer with.

Run diagnostics on the drive it may be failing. If it's ok you can try to reformat it from Windows Disk Management.

Or if you need to recover data for remote data recovery and do-it-yourself data recovery see http://FreeDataRecovery.us

In this case you should use data recovery software to recover the files and data.

This tutorial describes the procedure to recover one volume when

• the volume was accidentally formatted
• Windows reports the volume is "raw filesystem", or "not formatted"
• An external drive failed, either flash (so called "thumb drive") or an hard disk connected using USB or FireWire enclosure.
• MFT is corrupt on the NTFS volume, rendering filesystem partially or completely unreadable

The recovery is done in seven steps, requiring about eleven (11) mouse clicks. Note: The older than current versions of ZAR might have been used to create the screenshots in this tutorial. We did not update the screenshots if there is no significant difference between older and current versions. If you see some option in the program which is not described in the tutorial, just leave it at its default setting.

Step 1 - Get, install, and start ZAR
Download and install ZAR just like you do with any regular program.
When you run it, ZAR displays the window like the one below:

1. Click "Next >>"

Step 2 - Select processing mode

1. Select "Recover data from a simple volume or from a functional RAID volume"
2. Click "Next >>"

Step 3 - Select physical device to recover

1. Select the appropriate hard drive
2. Click "Next >>" for a list of volumes (logical disks) on this hard drive
