Hi,
After a resize attempt with partition magic 6 I cannot access the data on my
second drive.
It had 2 parttions
1- windows (fat32) ~10mb
2- linux (mandrake) ~10mb

I've used linux to delete the linux partition and then tried to resize the
win partition to take the whole space.

I sent the drive to a tech but I got back corrupted files and many bad
blocks.

I used ' findpart tables fp1-2.txt ' and here is the result:
----------------------------------------------------------------------------

Findpart, version 4.42.

None.

Is this of any help?

thanx.

Thank you for taking your time again.

I took the drive to the techy and it took a lot to get it back. Sorry.

I think this is exactly what the tech tried to do. But we got only partial
files. I mean, the image files were truncated, I could only see part of it.
And there were duplicated file names, also. It looked a mess to me.

Since I was trying to resize one partition to take the whole disk, and the
process was almost finished when PM6 hung, do you think I could overwrite
the actual partition with the new settings? What, I suppose, PM6 failed to
do.

No. Until before the resize attempt, the drive was jsut fine.

Thank you very much

Renato.

The case was discussed in a thread May 7-8, which I now read again.
Why did it take you so long?

Anyway, one method will be to insert a new disk, and attempt a sector
by sector copying to the new disk. And afterwards attempt normal file
recovery from the new disk.

I suggest that you initially get a new disk in the system, or put the
problem disk and a new disk alone in another system, without any
guarantee that the recovery will succeed.

If the disk is more than twice the size of the problem disk, there
will be room for both sector by sector copying, and file copying
afterwards if possible.

It would be possible to attempt file recovery directly from the
problem disk, but it will to time consuming without hands on based on
the description.

You said you sent the disk to a tech, and got it back with many bad
blocks. But the bad sectors were there May 7?

I have had similar problems when installing LINUX on a Windows system.
Several, in fact.

The Bottom Line, for me, seems to be to install linux on a separate HDD, or
a new system.
