Problem recovering partition/filesystem
Posted: 31 Mar 2012, 22:09
Hi,
First of all, thanks for making this utility available for free.
I have a major problem at the moment and hope you can help me. To make a very long story short I have a failing RAID5 array (HW-based Megaraid 8708ELP). I think that the controler may be failing and my 6-disk array is currently running as a 5-disk degraded array. The array have also encountered additional problems and dripped an additional disk, but I managed to get it up and running after reboots and adding the failed disk back to the array. I have tried re-build with new disk, but something seems to be very wrong and re-build is no longer an option, I need to get my data off the array (aprox. 4,5 TB of data).
My WHS 2011 (Windows 2008 R2) does not recognize the raid5 partition any longer and wants med to "initialize" the disk, but I guess this would totally f**k things up, so I have not done that.
I have tried a multitude of tools and managed to get the mbr (GPL partition) up and running by analyzing and restoring with PartitionGuru Pro. This made it possible to get some of the data of the drive, but during the transfer a disk dropped out of the array, I had to reboot, attach the disk to the array again and it was lost to the operating system again. PartitionGuru can now only find an partition with the following atributes:
But it does not contain ant files...?
Running your utility gives me the following result:
But "list files" give me the following result:
I guess that the partition is found, but he file system is corrupt? I have not been brave enough to save the partition data yet, as I have no clear understanding how this would relate to the file system. I noticed one thing of interest, PartitionGuru list the volume label as "Unformatted", but TestDisk lists it as "Data1", the name I gave to the RAID5 virtual drive...? It finds the MBR (GPL) at the same cylinder (16) using both programs. I will run a deep search adn try to update the post, but as you can imagine, this will take some time and I´m really worried my array will fail again soon.
Any ideas on how to fix this or how to get the files of the drive?
Best regards
