External hard drive partition deleted

#1 Post by smm867 »

Hi everyone,
I've accidentally deleted a partition on my external HDD drive using Windows Disk Management tool. I'm trying to recover partition using TestDisk, but without success. When I run quicksearch in TestDisk it last only couple of seconds and goes up to 99%, and stays like that. After I stop it manually I can use write command but I get "Partition: Write error".
I wound be very grateful for help.

Specs of my PC:
Windows 11 Professional (x64) Build 26100.4202 (24H2)
Intel Core i7-1165G7 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz
Motherborad ASUS B1500CEPEY, chipset Intel Tiger Lake-UP3 PCH-LP
NVIDIA GeForce MX330
Total Memory Size: 24 GBytes

You have to grant admin rights to TestDisk.

Hi, thank you for your reply.
I'm running it with right click and "run as administrator". Isn't this enough?

Your disk does not replay to read commands at the beginning of the disk.

Check your SMART parameters:
viewtopic.php?f=5&t=10910

It looks like there is more than just your deletion operation.

Try out the various -d parameters.
Alternatively you can try out CrystalDiskInfo if that gives some information (yes, I read the report stating "SMART disabled"!).
Unter Windows using HxD as admin you can try to scroll through the sectors of the device. Does it read something?
Another option is removing the disk from its enclosure and running it directly in a desktop computer.

If everything fails, contact a professional recovery service.

Sometimes the chipsets that the manufacturers use do not let pass the SMART-related ATA command.

Once again, huge thanks for your help!
I'll definitely go with the "removing the disk from its enclosure and running it directly in a desktop computer" option because right now CrystalDisk doesn't even see the disk. If it reads anything I'll come back with new information.

Hi, it worked! I removed the casing and connected the drive to my desktop computer and ran TestDisk. Quicksearch was executed without errors and I could write new partition table. All of my files are safe and sound :D .
Thank you very much for your help!
