Hi
Can someone suggest a professional Linux Ext 3/4 file system recovery tool ? ( windows based)
Linux partition is accidentally deleted.
Already tried following --
R-studio -- not satisfied
PC3000 UDMA --- no result
UFS explorer --- Not even detected Linux partition
and few others - one tool is giving good results but before I update customer I want to reach maximum efficiency

Have you tried UFS Pro or regular UFS? Pro version works quite good with Raid. http://www.ufsexplorer.com/download_pro.php
And when you say Pc3000 UDMA, I assume you have the Raid edition?

And then, there's GParted. I know, it's not windows-based, but you don't need to have a linux partition either, just make a bootable cd or usb and you're good to go. That should work!

McDonald's sells Big Macs, but that also has nothing to do with the OP's issue with a deleted EXT partition. Although some RAIDs have EXT partitions does not mean that all EXT partitions are on a RAID.

If R-studio didn't find data - there is no data or you need pro with good knowledge of ext3/4.

Very true It was my preconception, I must been working to much with Raid last days

Guys Thanks a lot for all Suggestions.
Here is my observation --



This is not true ,Data is fully present on the disk , I have already traced aprox. 1.7TB data. So far I have recovered 356 GB Data.
This disk seems to be used in some factory in design dept. It is having large no. of files ( more than 4 lacs , 400000)
I have discussed case with developer and he has also confirmed that results are as per expcetations.
All I want to ensure that maximum technically possible data is extracted . If I get any other tool , that will improve my knowledge and tool collection as well.

No I don't have Raid edition , as lcoughey has said ,I think raid edition is not needed in this case. Unfortunately udma did not give good results.



personally I don't have good experience with freeware tools. Often recovered data is not having proper directory structure .

It would be helpful to know how the filesystem was deleted but in general Linux ext2/3/4 stores multiple superblock copies on the drive. Your best chance "to reach maximum efficiency" with this recovery is to mount the filesystem using one of these alternate superblocks.

But afaik this needs to happen from Linux. I have a process that will try to mount a filesystem using all possible alternate superblocks. If you would like remote help let me know.

So tell us what is program better than R-studio and UFS Explorer.

Wo great Thank you so much.
, Manual recovery at a times is far better than automated process. I will be more than happy to see how you mount file system.
Pls. let me know your convenient GMT , I am +9.30 hours to Massachusetts.

I sent you a PM.

A big Thank You

Any chance that this would have been easily resolved with testdisk?

Hi lcoughey

I have just given a try to testdisk ,but it says recovery not possible.
I have often observed difference between free softwares and commercial ones. Possibly testdisk is unable to handle large no. of files.

anyway thanks.
UFS support technican has remotely analysed partition and has suggested some changes. They have also a new software (http://www.sysdevlabs.com/product.php?id=rxp6).
I am now trying reclaim me and will post results.
