Lost Data Recovery

This worked for me a couple of times.

Best is to get a separate power supply and interface, connect to your HD after taken it out of your PC.

Mines were making a lot of noise, but I had a 100% recovery with the paid version.

It is a little bit difficult afterwards to get everything back to normal on a new HD, since easeUS creates its own classification and filenames, mostly long numbers.

Piriform's recuva is freeware. I don't know if it has settings to recover the parition but will recover the individual files.

Good idea/recommendation.

Both of the suggested programs are included in the 4 I've downloaded for free.

You run them, they show the files, but when you try to save the files to a backup location, you get the "Buy now for $69" popup.

I have backed up the hard drive previously using Tortise SVN software repository, but the hard drive is undamaged, passes all tests, but has had the partition damaged by an older software install package from Endress and Hauser. The install opened twice with two instances running at the same time and somehow wiped out the partition. I'd like to save the drive by restoring the aforementioned picket fence (partition)

Have you tried to restore from a previous date...? If you have backed up your files, why don't you just reinstall windows....?

I have used Piriform's Recuva for years and has never prompt buy anything. Did you down your copy from Piriform's site or some other?

Good point!

all 4 programs ask for $69?

sounds like you have something else that is "seeing" a harddisk scan and blocking any "save" with a hijack and $69 demand.

do all 4 ask you to send the $ to the same place?

Yup, sounds like a data scam now that you mention it.

It's called RANSOMWARE and you can do your own search on the internet to learn about it.

The FBI has a web page dedicated to reporting ransomware attacks.

If that turns out to be your problem report it at: FBI Ransomware Reporting

Good Luck!

You may have to run the machine in "Windows "x" Compatibility Mode" in order to recover the partition and DATA.

Select the program, right click, and select whichever compatibility mode is applicable.

Have you tried the 'freezing the hard drive' fix?

It works fairly often when a hard disk has crashed. You stick it in the freezer and let it get cold, then quickly take it out, plug it in, and try to copy as many files as you can before it warms up.

First, how much is your data worth?

Personally, I woulds stay away from the DIY software as it could cause more problems than it fixes.

The best solution is to send the drive out to a professional recovery service and have it restored (if it can be).

That will probably cost more that $70, but it has the highest success rate.

If anything you have now learned the value of backing up your PC on a regular basis.

Some computers will let you recover a partition by pressing ALT-F10 during boot. ...worth a try....

You should be able to restore your drive to a previous date before this incident occurred as SE has suggested.

If it is a program that automatically runs on startup, Hit F7 on your keyboard as soon as you push the start button on the computer and continue to hit F7 during startup. This will start in SAFE mode and no imbedded programs should run until you direct them to do so. Then you can reset to a previous date and time and start again as normal.

Good Luck.

Not if the partition is damaged.

Windows does not recover lost or damaged partitions. Such an action as you mention, goes "back in time" to a point before say new (bad) software was installed, or before a bad update to windows, for example....

You are mixing up an OS recovery with the loss of data on a hard disk....they can be combined, but the recovery will not work as you appear to think it does, especially if a partition has been lost or data damaged....or both.

If a partition, say the boot partition, has been lost, that drive might be repairable in another PC, but not in the one which does not boot anymore, or better said MOST unlikely.

To help you with the full understanding of the problem, for example, a disk drive is dropped accidentally, the heads hit the disks hard and take off bits of the magnetic coating of the disks.

The area damaged is where the OS is stored.

Now how will a system recover missing actual bits of hard disk?

Not possible of course....usually such drives will make bad noises alerting the user to such damage...

You could, on a modern computer, possibly use an external disk or stick to boot up and then use software stored on the stick, for example, and recover as much data as possible. There are Unix CDs which can be booted to allow actions to be made on a damaged drive, but depending upon the type of damage. Physical being harder than logical....to fix!!

The only safe way is to have at least two copies of all important data, all the time....one copy in another geographical location of course...

A reinstall of the OS is often a good idea anyway as Windows for example, gets "cluttered".....so I don't save that ever....though such a re-install recover takes far longer!!

I hope this helps anyone with such problems further......

I am sorry Andy, I thought he said it was not damaged and it passed all the tests, this is copied from his post above:

"I have backed up the hard drive previously using Tortise SVN software repository, but the hard drive is undamaged, passes all tests, but has had the partition damaged by an older software install package from Endress and Hauser.

I don't think he dropped, he seems to be saying some software is screwing up the start up.

Maybe he should just take the rig to the shop and pay the $70 and be done with it.

If what he says is true, the partition cannot be recovered by the same PC (unless you give it a new system drive first!), then probably.....

"Recuva" is supposed to do a good job, (run on another WORKING PC), as is the software I posted from EASUS.

It may even be possible to use a Unix boot CD and do some good repairs.....though I have never tried it....

Full backup is the only good method, then you format the duff disk, test it and reuse it if it passes....

The recuva software returns a message: "Failed to scan the following drives: E:: Unable to determine file system type".

This computer does not have a virus or hijacking program. It's a work PC not used for web surfing or email. It also has half vast virus protection

I'm currently trying Mini Tool Partition Recovery Wizard. It seems to have found the files and I'm doing a surface scan of the affected sectors. I will update the progress of this.

If the memory loss is due to a physical head crash, then repeated attempts to recover the data could very well render the data unrecoverable.

This is why I said that if the data is really important you should employ a professional service. If not, you can keep trying to hack the data yourself. However, after awhile you have to ask how much is your time worth, too.

Your engineering track might be affected.

That is why I suggested a separate interface and power supply. I bought one from China on ebay for $24.00
