I have someone else's 1.5TB hard drive (WD Elements) that I would like to repair or recover files from. It has possibly been dropped and was constantly around a lot of loud Techno music. It is the standard format from OSX; EFI table, with a HFS+ file system taking up the entire disk.
On owner's request we used Easus Recovery Wizard, which found all the files, but then after, the files recovered were all unreadable; I don't have those files anymore, but the user reported OSX could not recognize any of the files as the types reported, or open the files at all. I don't have Spinrite or any other commercial recovery software around.
On OSX the disk doesn't mount.
Disk Utility GUI in OSX says that the partition table is in-tact and recreates a windows boot.ini file, but it will not mount the HFS+ file-system and says something like [I am paraphrasing this from another language]:
"Incorrect node size of B-Tree-Headers, Exit code 8, do "Repair Volume"
...after clicking repair it gives the same message, and additionally...
"It is recommended to repair the Boot-Support-Partition" "Failure of the Disk Utility, save your data somewhere else."
Testdisk reports on the quick scan:
check_FAT: Unusual media descriptor (0xf0!=0xf8) Warning: number of heads/cylinder mismatches 16 (FAT) != 255 (HD) Warning: number of heads/cylinder mismatches 32 (FAT) != 63 (HD) EFI System 46 409645 409600 [EFI] Mac HFS 409640 2929948631 2929538992
but then shows the table and partition as in-tact (green colored on the terminal screen), and like the other recovery software, it also will allow me to make a disk image.
I did the entire "Deep Scan" of Testdisk, which just came up with no additional partitions found.
Any tips on whether to proceed, and how to possibly recover the files, or what further, exact data would be truly of use to help repair the disk would be really appreciated.
