Delta file corrupted - any way to recorver data?

[mustafa5820]

Hello,

3 days ago i get hdd failure:/ (bad block)

I recorvered what i can but file are corrupted.

I have all file from VM but one i corrupted. (delta file) normal size 6640M and my corrupted size 6268M. Other files are fine (flat and etc). But flat file is dated -> DEC 2012...

Is any way to recorver younger data?

I read much site and faq but nothing work on my file;/ (clone vmdk, mount)

example

vmfs/volumes/527e6bd9-7595b9a7-8462-00237d3fc1a6/kopie/Ksiegowy Windows Xp # vmkfstools -i WIN_XP_KSIEGOWY-000001.vmdk test.vmdk

Failed to open 'WIN_XP_KSIEGOWY-000001.vmdk': Input/output error (327689).

vmkfstools -x check WIN_XP_KSIEGOWY-000001.vmdk

Disk is error free

vdk, vmware mount, winimage cant open file

hI
the lsltr.txt does not seem to be related to what you posted before - please check the attachment

@dGeorgey I read that topic 2 days ago and my conclusion:

My flat file is fine, my CID and parent CID are ok. Delta file dont have disk geometry then i dont need to change description of delta file?

@continuum 'ls ltr' i've made on copy of recorvery folder. Is fine, maybe i say something wrong?

Ok - somehow I viewed the wrong file after downloading the lsltr.txt

Do you still have the disk with the bad blocks ?

My plan A would be: read the original volume with vmfs-fuse and extract the bad delta file with gddrescue.
If that works it will fill the bad sections with zeroes.

Plan B: - edit the delta-file with a hexeditor to adjust for the missing space - that is highly experimental !!!

you can call me via skype "sanbarrow"

Yes i have but this isn't so simple.. I use RAID0 (yes i know...). My controller HP E200 disabling logical drive when i want read any bad block. When i use MHDD stricle on failure hdd (without E200) and want reapir any bad block then i get timeout and i need restart computer. I've used hdd serial port to recalibrate translator, clear p-list and user level format (not writen to plates). This help with bad block but is very possible to lose all data (When i do that i was sure that my recorvered 16200M will be sufficient).. And that is my story;-)

Now i go check my failure hdd what happened... i'll be back=)

@continuum Can you say more about plan B? (how do that - i know what is hex edit) structure of delta file? maybe begin_header+DATA+end_header ??

dump the first 8mb of the deltafile with
dd if=name-00000*-delta.vmdk of=delta-8mb.dd bs=1M count=8
and archive it and attach it

I edit it and send instructions how to apply it

- and if possible - work on a backup of the delta ....
