I somehow locked Myself out of My 2nd drive
And I thought I could restore security settings to default by formatting and reinstalling Windows XP Professional SP2 .
I was wrong . Now it looks as if the 2nd drive is empty and when I try to access it Im told it is not formatted .
Is there a way to restore the filing system without reformatting ?
I do not want to loose all My data Please Help Me !

Do you know what type of file system was on the disk i.e. Fat32 or NTFS?

Give this a try and scan the hard disk:

Define what you mean by locked out? Is the second drive a physical drive or just a partition?

The File system was NTFS
And it is a physical drive

I tried the PC Inspector File Recovery
bad parameter in boot sector: Bytes Per Sector (0) = 0!
I do not know what this means

You can try:
"boot from startup floppy disks or CD-ROM, choose repair option during setup, and run Recovery Console. When you are logged on, you can run FIXBOOT command to try to fix boot sector."

Can you give us more information, as Scott suggested, about how you locked yourself out of the drive? Did you encrypt it?

Well it all started when I was trying open some files I created and was denied that's when I started poking around in the security settings to see why . I am the only user on this PC I am the administrator .

I assume there is no drive letter showing up in my computer?

Not to jump around on the recovery software but give this one a try:

I have had some success with this also, I find that some programs just work better in different situations.

Is this computer on a network (LAN)?
Is it on a domain or a workgroup?
