Invalid Dynamic Disk, How to back partitions?

#1 Post by naiem » 04 Jun 2015, 18:29

First I'm sorry for my English, I don't know English well!
I have a 500Gb Seagate HDD that had some partitions and my disk was dynamic.
after a windows re-installation my disk changed to invalid and I can't access my partitions!
and my disk can't be converted to Basic Disk, no way!
I have tried many partition manager and recovery tools, but I didn't try test disk yet!
please help, how can I back my partitions?

Can you run a diagnose and copy and paste the content of your testdisk.log into your next post?
Youl'll find your testdisk.log within your testdisk folder.
You should run Analyse / Quick and if partitions are not found Deeper Search also.
Please mark each found partition and press p to have a try to list your files.

More Information, Screenshot and log file
I had 10 partitions on my disk before the problem: 9x52GB + 1x17GB. I don't know they were primary or logical, but logical I think because I created them by windows disk management and I didn't have OS on none of them!
Here is a screenshot of Windows Disk Management after the problem that show my disk is invalid:

And here is the log file from Testdisk, I don't know how to create log file, I follow this: Create, Select my disk and Proceed, Intel, Analyse, Quick Search, I saw a list of my Drives, 10 Drives all are Deleted "D", Enter: To continue, and then quit ; I hope that was right, If it wasn't tell me how t create log file:

So, How can I back my partitions with all data safety?

As I said before, I had 10 partitions on my disk; 9x52GB + 1x17GB. in Testdisk after Quick search, these 10 partitions have been found:

What should I do now? Will all of my partitions back safety if I change Letter "D" to "L"? then I should write changes, right?

Your first partition overlaps your second partition and if you´d like it to get it back as Intel-MBR basic partitions, there is no space left to create an extended partition.
Example:

NTFS, blocksize=4096, 52 GB / 48 GiB
Can you try to set the first and the second partition to P for primary only?
You should check each partition and use your left or right arrow key on your keyboard to set them to P for primary.
You'll see it at the left side.
Did it work?

The red highlighted values are the end and start sector of your fourth and your fifth partition.
The fifth partition starts with the next sector after your fourth partition.
Can you try to set them to L for logical using your left or right arrow key on your keyboard?
Do you get a message structure bad?

Please let me know.

No I can't set first and second partition to P, one of them yes, but for both No! I get a message structure bad, for 4th and 5th to L, I got a message structure bad, too.
Even I Can't set two consecutive partitions to L or P!
I can set partition to L or P i these three ways:
1-
Image
2-
Image
3-
Image
What should I do now? I need all of my data, the last 5 partitions are more urgent!

I'd suggest to copy/backup files first running testdisk.
If you list your files, at the bottom of the testdisk display, you'll find all the commands.
Standard path is the testdisk folder.
If you'd like to select another disk or partition, you can check that 2 dots in the upper area of the testdisk display and press enter.
Each time you'll get one directory up until you get to your disk selection.
If you'd like to copy your data to another folder, you can create a folder in advance and in testdisk easily mark it and use the right arrow key on your keyboard to enter it as your target.
You could create for each partition a folder.
This would be a safe solution.
After datarecovery, you can delete all partitions and convert your disk to basic disk.
You can create 3 primary partitions and 1 extended partition for your logical drives and copy data back.

If you decide to recover some partitions first, you can decide to decrease the size of your partitions using your disk management console and afterwards to recover all the other partitions.
But this is not a safe solution and shouldn't be done without backup.
In case, please let me know and would be on your own risk!

Fiona
