Changing Partition type ....

Vittel · 07-19-2005, 03:30 AM

I have 2 hard drives.
First hard drive is 40GB and contains both Mandrake 10.0 and Windows XP.
Second Hard drive (D:\) is ntfs formated, and acts as a slave for all my data.

I used to be able to access the d: under mandrake with no problems. However, after access a usb stick it seemed to disapper.

Anyway, I was having a tinker with the Partition manager under Computer configurations.
Linux was seeing the partition as NTFS, but it it couldnt see the files
I clicked "Change Partition Type" and acciedently clicked OK after the warning came up.
I did not change the partition type, but I did click OK. (SILLY ME!!)

Now when I log into my Windows it says that D:\ is not formated.
Ive tried everything I know possible to try and recover the files, but to no avail.

Is there anything at all I can do to recover my files?
I would be distraught if I lost them all.

Thanks in advance

Maybe gpart can do the job but use it as your B plan because it's a very powerful (and then dangerous tool) and there could be other easier ways for trying to recover your data.

Backup youre stuff, format the drive with the type you want , copy the stuff back.

Ive finally managed to save it!

It was the partition table that was screwed somehow and windows explorer was not recognising it. However, I tried a number of data recovery applications and they saw my files percectly.

Im now happy again!

Ok, I kind of did the same thing, except I accidentally created a swap out of my my hda2 drive..

I tried using r-linux, but it created a bunch of $Inode files on my winodws system, how do I convert that back?

First of all, sorry about my english.

How did you recover you partition? I'm having a similar problem. I accidentally changed something in my Volume Group configuration, and now my Fedora Core can't boot, and I can't even access my files. I figured out that if I change my root partition type from 8E (which is the current type, a Linux Logical Volume Manager partition) to 83 (which is the Linux native type), but I don't know how to do that, or if it's even possible

. Any suggestions?

You can change the drive partition type by using the fdisk command. Type fdisk then the drive mount position ( e.g. fdisk /dev/hda ).

Thanks, I was searching for that info right now and i found it.

--------
You can change the partition type using the command “t”.

Command (m for help): t
Partition number (1-8): 8

You will be prompted for the partition number of the type you want to change and will be followed by:

Hex code (type L to list codes):

Each partition type has a number assigned to it. For the most part, the hex codes of the partition ID's are unique. In some cases, there are conflicts - Solaris partitions and Linux swap share the same ID. If unsure of the Partition ID, use “L” to check. As you can see, fdisk supports a wide variety of partitions from FAT to BSD to BEOS. We select 82 for Linux swap.

Hex code (type L to list codes): 82
Changed system type of partition 8 to 82 (Linux swap)
--------

I will try that... Thanks. I hope that it works, I've been strugging with this problem for months :S
