RAID 5 Strip 8 hdd 146 each Data Recovery

[DataPlanet]

Doing Remote Recovery 8 hdd RAID 5 strip forward 1 hdd damaged showing 0 mb clicking all other 7 working find then I reconstruct the RAID it showing me boot sectors in Hex and show 3 partition after reconstruct. Data is showing proper with correct file size then i made a recovery of 48 gb of .doc .docx .xls .xlsx .pdf ... but 99% data is corrupted only few files are opening... I know without 1 hdd RAID 5 can be reconstructed.

Any proper solution recommended a $ 200 reward for successful solution.

The solution must be share privately PM or contact@ditplanet.com

What is the RAID-5 stripe size set to? And for the 1% of the files that appear to be valid, are they all small files that are the same size or smaller than the stripe size? If so then it is likely the stripe size. If some larger files (up to 7x stripe size) are valid then it may be the drive order. Please provide more info on your scenario: Software used to rebuild RAID, drive sizes, stripe size, order, rotation, etc.

I am not an expert
have you used used UFS Explorer latest ver. it detects the RAID parameters automatically, an was quit a successful in many cases i solved.

1. So, how are you remotely connected?
2. What was the result of each drive clone?
3. What did you use to clone?
4. To what did you clone?
5. In what kind of hardware was the RAID?
6. Software or hardware RAID?
7. Are you sure that you have the drives all in the correct order?
8. How experienced is the user at the remote end?

Now connect again to the user I found that 2 more hard drive has serious problem bad sector one has full and one has little cloning will not help it will also show corrupted data because RAID is not "MOUNTED" and risk of further damaged.

Additionally I am trying to approve a service charges of $1500 so I will offer $500.

You may be wanting to add another zero to those numbers.

The data is already is in lost stage we people try our best nobody know what next in DR but this is not a mean that i am not careful... and I think DR pro are discussing if you are not then away from the post.

TXRanger:

Your post is helpful may be it is stripe size problem i am using default 64KB try 128 and 256 same result client has no such information we hardly correct the order of the drives.

You can check remotely send me your contact details. PM

If you are sure that principal parameters are correct, then it could be a vendor-specific RAID with non-standard pattern, or there was a rebuild of some kind, e.g. a forced one, which could have destroyed parity.

$1500 is barely feasible for an 8 drives RAID 5 even without any irregularities. If there's a non-standard data distribution pattern and/or more drives are about to fail you should charge more and offer more for assistance.

Its possible the raid lost a drive a long while ago ( due to bads for example ) and no one noticed , the raid continued to run on parity until 1 more drive died (started to click). The reconstruction you made in that event uses the drive which data and parity data is out of sync with the rest. All in all you can only deal with raids remotely if you have proper images etc.

Thanks for the suggestion Dmitri & Alexii case is still open update when connect again.
