Data Recovery (Deleted folders) for Raid 5 EXT format

[drHDD]

It's funny that you are start talking about pro but some how you are finished with company. Pro is person, not company.

Apologes but are we going to digress any futher here ?

I appreciate many want to keep knowledge and experience to themselves but , I prefer to share my knowledge and experience where I can with others - I just haven't done here yet as I am new but, you can search my username on many other forums - perhaps I should do an introduction

anyway back to the topic in hand


Which recovery software are recommended (tried and tested ) for my environment

Raid 5 EXT deleted files

What time-frame are we looking at days/weeks/months/years ?

OK, so I was correct then to assume you are doing the work from home. When we talk about pricing for "pro" recovery it's based on assumptions that include the costs of rent & utilities for office space, taxes, employees, phones, internet, accounting, etc. etc. etc. etc. which multiplies costs exponentially. If I had zero overhead and worked in my garage, I could probably do RAID recoveries for $400 too, but that's not the type of "professional" company most people want to send their data off to.

Please don't mistake this as me coming down on you or questioning whether you could handle the case. It's just that your pricing you offer is comparing apples to oranges.

@90Ninety Remote RAID / NAS data recovery using Linux techniques has been my specialty since 2011.

I offer a free / donation option after a nine day waiting period.

My site is: http://FreeDataRecovery.us

I am happy to take a quick look if you like.

Why you decide that you are correct? I don't see anything in my post to help you decide in this way. I am paying cost and rent, utilities, taxes, phones, internet accounting, tools and etc. I don't have employees.
Professional company first of all should have professional engineers and technicians - all other stuff is next, not first. I see a lot off you guys talking about how difficult to change heads like example - I don't see why it's so difficult. I am changing heads on drives with rings sometimes 20-30 times a day. This case with deleted files in ext4 - what so difficult in that case? You don't need to rebuild raid. Information about files positions - gone. It's almost raw recovery case with possible manual things which could help to get some good files.

I was looking for job recently and I talked with data recovery companies owners. Everybody wants to pay no more than $29 per hour to engineer. And I see your prices for recovery ... Guys who is getting this huge difference between what you are getting from clients and what you pay to actual person who is doing this job? And after you are blaming me in low prices?

This comment did.

Pro is person, not company.

Your deliberate detachment of professional from a company, tells me you're not here representing any company. That and the fact you still won't say what company you're with.

You also say:

You don't need to rebuild raid.

Which confirms that you don't really know how to handle such a case. So you're not a pro with or without a company.

And I guess you can add unemployed to the list.

Perhaps you were offered such a low salary because that's all they felt you were qualified to receive.

It's very easy to look at companies and think that they are making a ton of money based on the billing rate alone. But, if you'd ever actually owned a company you'd realize that's not even close to being a reality. I like to think I run a fairly successful small data recovery company. Our billing I suspect will be well over $200,000 this year (not bad for two people). But, would you believe that after write-offs and expenses the company only made $38,000 last year. Granted, I have other income from my real estate ventures and I was intentionally investing into my business last year rather than taking home any capital. Was focused on growth more than profitability. But still, it's easy to look at my rates and say I'm making a "ton of money" even though it's not even close to true. Doing work the right way costs a lot.

I'm not a pro, but ISTM that the NAS needs to be disassembled, the component drives cloned, and then the RAID needs to be mounted as a local drive in order to gain sector-level access. One could use mdadm to assemble a software RAID under Linux, then the appropriate data recovery tool(s) could be run against the RAID.

I don't believe any part of such a procedure could be seen as a "rebuild".

I think what drHDD was suggesting was just running a RAW file scan on each individual HDD and taking what you get that way.

[drHDD]

Tell me how pro could be company? By which things you can tell is this pro company or not?

TS NAS is still alive, isn't? Why you want to rebuild raid? Just for fun? Or to get more money from client?

I'm not saying a company is a pro, I was just saying that you're clearly not representing any professional company. And you've now admitted to that yourself, so my postulation was correct.

You're not going to be able to get direct sector access to a NAS to perform a RAW recovery without modifying the data at least somewhat (thus risking overwriting data in the process). So the proper method is to remove the drives, clone them for safety, determine the parameters and build a virtual array which you can then scan using software.

If you're lucky it may be a typcial Linux mdadm type of RAID that Linux can recognize. However, it's just as likely to be a hybrid RAID that it won't.

[drHDD]

If working NAS is a problem for you and you need to rebuild raid - like really rebuild with searching order, stripe size and etc - I understand why your company so inefficient.

Ha-ha. Why? why you think that your opponent so stupid?

Oh yea. You make me laugh. Thanks.

Exactly. Thanks fzabkar!

I read this and did not quite understand all. Everyone want to help him or not?
I see only drHDD says the right things.

I am professionally engaged in data recovery for more than 25 years and can restore many NAND flash and hard drives that cannot be recovered in other data recovery service.
Our main job is - to restore data after other companies that are not able to do it.
This is very simple RAID. It is logical case !! Even if one drive in the raid will be damaged only need other good drives for success recovery for Raid 5 , and anyway it is logical case !
Our company sometimes restored the data for free of charge for family with low income.

To: data-medics: Our income is mainly from the big oil and gas companies and state-owned, government sources, police forensic cases and more...
We make $800 - 1500 K per year and have great benefits to pay less taxes.
If you pay too much taxes and have a lot of expenses you or lie to us, or simply do not know how to count money or how works revenue system ! Use tax optimization!
We can do data recovery from this raid for $ 400. If you have any questions please contact, I am ready to answer and help.

To : 90Ninety . Please contact us directly, we will help you.

And for all guys for future - do more business and help to other with fewer words ok?

So, then how exactly would you get raw sector access to the NAS to search for deleted data without writing any data whatsoever to the NAS? I'm not saying it's the "easiest" method. I'm saying that taking the drives out, cloning, and building a virtual array is the "right way" to do it.

So then why does your pricing page say you charge "$300 per drive" for RAID arrays? (http://datarecoveryexpert.ca/Prices.html) Yet you say you can recover this one for $400 sight unseen.

I don't remember the OP ever even mentioning the number of drives or model of the NAS.... so what if it's a 16 bay Qnap? Still going to do it for $400....?

[fzabkar]

DMDE will assemble a virtual RAID. It will also search for deleted files in ext2/3/4 file systems.

Ok boss, with 6 posts in 3 years.

but by looking @ the attached image (from your prices section <<--- your website
if you charge 150-500$ for flash and you think that we should HELP OTHERS WITH LESS WORDS i think you could lead YOUR TITLE here
and offer more than 6 posts in 3 years.
