Recover data from external drive with no partition table.

#1 Post by WekK »

I have an external drive that has no partition table (I think that's the term, sorry I am new to this). I mistakenly selected this drive when I was trying to format a USB drive. The drive shows up as unallocated in Disk Management. Commercial software is able to list all the files and PhotoRec is able to recover all files. I am trying to use Testdisk to recover all the files with their intact names and possibly their tree directory. I tried analyzing the disk with Testdisk but it won't list the partition with all the files. The only files I can list and recover are BOOTX64.EFI and GRUBX64.EFI. Is there something I am missing/not doing properly? Any advice is appreciated. Thanks.

I can't post the Testdisk analysis, didn't know it was going to be overwritten if I tried to do another analysis (thought it would either create a new log or append the it to the old log. Here is the log for PhotoRec, not sure if it would help.
