XP no longer sees my 2nd HDD drive as NTFS rather RAW. This happened once before and I was able to fix it with Knoppix. This time Knoppix can't mount the "unknown" format. I think the partition table needs repairing. Data Doctor sees my files on D drive. Looking for FREE software to do this seeing as I'll have to buy another HDD and I'm not made out of money.
Thx

This helped me

Free, but you need to understad a little about partitions to recreate it.

I also use partinfo from partition magic ( Free I think ) to figure out the cylinder start info.

I hope this helps !

While other aps say it's RAW, Fat32, or unformatted, all report the 250gb drive is only 58gb.

Partinfo for XP reports it's FAT16.

You need to fix the partition size using testdisk first if possible.

If not, you will need a low level disk editor PTEDIT or the windows PartEd ( I think ) to fix this.

1) Did you check the BIOS, to see how the drive is identified ?

2) It is possible that te HD died or is flakey, which is why it is not recognized properly.

3) Did you run the Vendors diagnostics on the drive ?

Yes, no, and yes.
Strange that the free recovery aps don't see my extra drive but paid aps like Data Doctor see all files just sitting there. Some aps only recover some files.
I've just ordered another HD to copy the files to. I may try a DOS ap next week just for fun.
In the meantime, I'm still searching for solutions.
Thx

Nope. Most aps don't see all the files. I'm stuck. Looking at "unformat" aps now and hoping someone will point out more free aps to me.

For Test disk, did you try both the Windows and DOS version.

On my machine, I had to use the DOS version since the windows version did not see the correct Disk size.

I hope this helps !

That's the major problem. Most aps only sees 25% of the disk.
Testdisk says::
This version should work under
- MSDOS 6.x
- FreeDOS
- Windows 95
- Windows 98
If you are using NT 4, Windows 2000, run the Windows version of TestDisk.
Too bad I have MSDOS 5.1 that came with XP Pro...I'm not sure anyone could figure out the directions anyway...even experienced users.

Bootable media floppy images are available at www.bootdisk.com for almost all of the above DOS/Win versions.

I'm back with ptedit32 for windows now. It says my file system is fat16 in the first column/row with the rest of the table's rows zeroed out. Not finding instructions on the net but learning never-the-less...very slowly.

Hey...I just noticed BIOS is reporting drive D @ 57gb which is wrong but when I try to dl activex for a bios upgrade scan, the screen goes black and the computer restarts. Hmmm....

I finally got testdisk to run but it can't recover the partition. Bios reports correctly for 3 other slaves so I believe D drive was damaged with the XP install to C. Microsoft fails to tell you to disconnect all other HDD's when installing.
Well, I guess this is where my 3 year warranty kicks in. They're sending me a new disk free of charge. Thx
