Windows 7: Partition not visible in My computer<<Used diskpart clean only.

Hi everyone,

I made the mistake of using diskpart clean (only NOT clean all) command,

on my local hard disk, so the command deleted the partition that does not contain

the OS and gave me an error message that it couldn't delete the partition

that has the OS. since then I tried using testdisk and it does detect my deleted


partition and i choose to write a new partition table option and reboot


but still i can't seem to recover that partition that has my graduation

photos that i have no back up for.

In the attached images you'll see that the partition is intact and i can even see

its content and but i don't know what's going on!

please guys, any nice help would be appreciated..

Thanks in advance!

P.S:

EASEUS is not able to recover since it says that "existing" and doesn't even recognised as

deleted or lost by it, so you can only browse the deleted partition but not recover.

Hello Salih,

If you mean the 3.99 GB unallocated space in your screenshot, then you might see if you may be able to pick up at step 7 in OPTION TWO of the tutorial below to restore the partition and recover the data on it afterwards.

Convert a Dynamic Disk to a Basic Disk

Hope this helps,

Seems after all that diskpart clean (only NOT clean all) does not zero the sectors and only delete the partition table

but not the data.

That's correct. "Clean" only deletes the partitions, and marks the data as deleted, while "clean all" does that and a secure erase of the data on it.

From what I understand, a "clean" actually zeroes out the first 1MB and the last 1MB of the entire drive (2048 sectors each).

Since the MBR and partition table live in sector 0 and the first partition usually begins at sector 63 (or sometimes 2048 in the case of Vista/7), the disk is effectively wiped out and reset to "uninitialized" condition.
