Data recovery and disk repair questions and discussions related to old-fashioned SATA, SAS, SCSI, IDE, MFM hard drives - any type of storage device that has moving parts

We want to improved data delivery to clients with more security and copy restriction. I regularly deliver data to clients to check most clients report ok... but in some got problem and we even don't know they already copy the data and saying this.
What I want is to deliver data with read only and copy protection. client can read it but can't copy it... may be this need some encryption.
Any advice will help the data recovery industry.

You always misunderstand me. before the payment i want to deliver as read only with copy protection and after that i want to deliver as enable copy. what is wrong with this protection?

@DataPlanet
File listing is not good enough as proof of recovery?

I know of at least on guy who uses a Synology NAS where he gives client access to a virtual desktop where they can view the files online...on his system. I haven't used these systems before, but I believe he can control whether or not the user has download access as well as being able to throttle the download speeds.
I personally prefer generating a file verification report using DeepSpar Operations Server. The client can browse the listing and see the file's recoverability status.

Connect the HDD to a computer with Windows Server installed. Creat one Username with Read Permission only (no copy permission). And let clients check their files remotely (teamviewer) logged with that Username.

We provide a file listing, and spot check the critical data the client asked for.
If it is a crappy recovery we asked the client to review the file listing and let us know Specific files to test to check their integrity. even files with bad sectors can still work, so we want to make sure everything is all good before payment is made and data is released
Work with your client, they will be happier in the end

we have standard practise and we never receive any complain from customer.
We always keep imaged copy of the patient drive till customer confirms that he had copied data to a secondary media or on his system and checked, normally 4-5 days we gave to customer for this.
when we perform recovery we know for sure that required data is ok or not, in case of solid recovery we provide a screen shot of required files or folders to customer as a proof with assurance of data integrity, once payment is made we deliver the data. Sometime we ask customer to check his data on our system through TV and confirm if it is ok ?
I don't know a single company who provide data to customer without taking the payment.

Such scenario is not easy to accomplish. Data reproductibility has been a major issue since before days of the compact disk, and it's been proved only special hardware or consensus on software development (like recent Mozilla agreement on deliver DRM content) is really effective in these cases. If you are actually willing to provide some good proof to your customers about the recovery, you might need to develop some "advanced" file list system in which you provide the customer with a browseable HTML file list, with miniatures of some widespread file types like JPG pictures or MS & OpenOffice documents. I can program such file list system for you if we come to an agreement.

Snap2HTML is a free program that provides a browse-able file list; you can burrow within folders by clicking on them to see a list of the files and their properties, just like in Windows Explorer. The author also has another freeware program, Snap2IMG, that provides structured HTML links to the image files, rather than to thumbnails, so that's not of much potential interest. I would think there's a market for such a program, especially if it also provided thumbnails of typical document files.

Great idea my question is solved your relationship with me is +160 and i give you reward of $50 and offer two free data recovery cases online. Yes I know about NAS and with NAS my client's will read the data online with copy restriction.

Thanks to invent the idea

Here's what I do.
For full recoveries I don't bother, as the client knows what was there and will get 100% of everything back so there's no need to show them what they're getting, it's their data, they know what's there.
In cases where it's not a full recovery, or some data is damaged (in DE saving damaged files to a separate folder for example) I use hddstruct.exe
I stumbled upon it for this exact same reason, I wanted to show users their recovered folder structure and file sizes easily. So you use the program to make a .pak file (a few MB in size) and send it to them, and they open it with hddstruct and that's it.

In 100% (or 99.99%) cases, we also take it that it's a good recovery.
But much less, then...
We use Data Extractor to save files with damaged (containing bad sectors) files in a separate "!problem" folder and then send two file lists, one with what should be perfect files and the other with suspect/damaged ones.
We ask them to check the lists and then also ask them to advise of any "mission critical" files so we can manually test them to confirm they open ok.
Don't know what else we can do!
To be fair (touch wood) we've never yet had a problem with unrecoverable data that we weren't able to resolve with the client.
In some rare cases, with massive media damage we only get a low % of data (maybe 10% of raw photos) so rather than give the client nothing, we offer them the recovered files for then cost of the parts used, no labour fees. If they decline, then we take a hit. It happens!

Recently I have had 2 customers that say there were pictures of such and such and that there were not present in the recovered data. These were both 100% recoveries, 1 was a USB header only, and the other was a Phison with standard mix and 0 corrupt pictures with folders and pictures to total of 6Gb.. but no trace of the 1 specific image set they were talking about. I don't know if they mixed up their cards, trying to get discount or what, but it is very frustrating when you know it is a 100% recovery.

I am going to practical the formula with NAS solution. it will give as more option to deliver the data with copy protection and it is onlne. This will must help us to improve delivery of data.

IMHO it is going to help you waste time while you tune this system to work and now you have given customers network access to your internal systems. I hope you understand network security.
IMHO a waste of resources and other options such as file list are well and truly sufficient

I just realised that hddstruct isn't easy to find. I can't remember how I came across it a few years ago.
I have it here
www.southbit.co.za/hddstruct.exeI'd like to give credit to the developer but it's not in English.
Try it, it's really useful.

The recommended DR people look like a who's Who of HDDGuru

Didn't even know it was Vlad's, I really should have. Thanks Franc.

R-click the file and examine its Properties, specifically Company Name and Legal Trademarks. It's all in English.
