Hello,
...suggests you should use GPT instead of Intel/MBR when asked for the partition table type.

I am pretty sure that the drive was originally partitioned with Intel/MBR.
But you used GParted afterwards.
In the meantime I went ahead with Intel table type and recuperated my partitions with data. Is this why I am getting these errors when trying deeper search with GPT, or is GPT incorrect regardless? Keeping in mind that I only went as far as 11% as I had to stop for now.
11% of what?
I went through the deeper search again and went through all the results and found the valid partitions (with all my missing files), but I hit a wall again. I could not change the partitions from deleted to either L or P past 4 of them even excluding the NTFS partition.
Try setting the first one to Primary or bootable and the rest to "logical".

Hello Recuperation!
11% of what?
I meant 11% of a deeper search, at that point at I peferred to shut things down. I could try one last complete deeper search with GPT partition table, but I am pretty sure that my drive was partionned Intel/MBR. In the past, I had previously re-partionned part of the drive with Gparted without changing the partition table and it was always recognised as msdos and sudo parted -l shows msdos partition table as well. Aren't msdos partition table and Intel/MBR used interchangably?
But you used GParted afterwards.
I deleted my partition in error in gparted first without changing the partition table, then I used testdisk to get my windows partitions back using Intel partition table.
Try setting the first one to Primary or bootable and the rest to "logical".
I tried all combinations: I can change the NTFS and the swap file partitions to P and allow 4 more partitions to be either P or L. Even if I change either partition to P or L seems to make no difference. And its irrelevant if I keep the NTFS and swap partitions deleted or not.

I am rather baffled, and in the meantime I am moving some of my files (from the 4 recovered drives) to my proper backup drive, which is what I was supposed to partition orginally! :(

Hello again!

When recovering my files, I found the testdisk.log from before I recovered the Windows NTFS partitions! It shows the logical partitions that were part of the extended partition, including swap! This is at the stage when I deleted my Windows partitions in Gparted without changing any partition structure.

What can I do at this point, I know I did select 'copy (NTFS) to partition', when testdisk warned that the partitions tables didn't match effectively changing something of the partition table, correct?

You ignored my advice. Most of those combinations you mention are technically impossible to realize anyway.

#16 Post by slipstream3 »

Hello,

I started doing a complete deeper search first with GPT and then I'll do it once again with Intel/MBR. I will try to change the first partition found that is valid to P then the rest to L and see what happens. Did you have a chance to view the testdisk.log that I recently found? It could be helpful! Thankyou!

Re: wiped out extended and logical partitions after trying to recover NTFS partition

#18 Post by recuperation »

Thank you for providing better information now. I was about to stop trying to help.

I checked my only Windows 7 Installation (32-bit, non-UEFI) to learn that Windows placed partitions directly on after another without any free space. That means that the old school Intel/MBR can be used.

I can only guess that Testdisk expects free space between your windows partitions because of the bunch of extended partitions that had been created by your linux installations.

Code: Select all

interface_write()
 1 * HPFS - NTFS              0  32 33   191  89 26    3072000

write!

write_mbr_i386: starting...
write_all_log_i386: starting...

You would need to manually add the first partition (just above).
Despite one log you showed it had not been integrated into the structure.
You might need to do stuff according to your individual boot manager setup.
You probably did not boot from your Linux swap partition "*".
There might be an extended partition "x" missing labeled number 4.

Strangely you did not say a word about accesibility of your partitions although they all showed up.

Re: wiped out extended and logical partitions after trying to recover NTFS partition

#19 Post by slipstream3 »

Hello,

Got a chance to give an update now! I am not clear on adding the partition manually for Windows, but I had an issue with my 2 linux root partitions that I couldn't figure out. Even if I left every other partitions as deleted, testdisk warned of these partitions as being: structure: bad, even if these root partitions were verified to be the correct partitions. At least I had my 2 home and 2 data partitions, which after a final deeper search, were still accepted by test disk as extended partitions, and the swap partition as well, and the Windows as Primary, so I wrote to disk again just as a re-confirmation for myself.

You were wondering how I accessed all my drives; originally, I was planning on just re-installing grub2. At this point I was running out of time for resolving this & since this laptop is now mostly a multimedia computer, I could allow myself to just wipe Windows at this point, and make some space for a new Ubuntu installation. (I was able to retrieve all needed files from the live disk)).

I re-installed a fresh version of Ubuntu with updated software, and at least I can replace all my lost software gradually if needed. I love open source based software and OS because it is so flexible among many things!

I wish we could have figured out why testdisk rejected recovering the 2 root drives? thankyou for your help as I am more clear on things at least!
