WD 250GB shows as 2047GB | can't read boot sector and backup

Hi everyone,

I'm faced with an issue with my WD2500BEVT 250GB hard drive. This is a laptop internal hard drive that I've used as external with an enclosure and has been using it for quite a long time without problems. Last time, my sister returned it by throwing it to me but missed me and it bounced off the couch (I know, she's an idiot) and hit the floor. Panicking, I immediately checked it on my Windows 7 laptop and was not showing on My Computer, I opened Disk Management and it was showing as 2048 GB Unallocated "Unknown" and "Not Initialized". I tried to initialize it but received an error "Data error (cyclic redundancy check)".

I've ran testdisk 7.0 but it can't seem to detect the partition. It says "ntfs_boot_sector: Can't read boot sector. Sector: Bad" and the same goes for the backup. Sectors are identical, however.

Now I've been running Rebuild BS for about an hour and seems to be stuck (I can't move the cursor), but I know something is happening because the enclosure light is blinking as if accessing the drive.

You should try to clone the disk using ddrescue as described in https://www.cgsecurity.org/testdisk.pdf Once it's done, disconnect the damaged fisk and use TestDisk on the clone or the disk image.
If ddrescue failed, you will have to contact a data recovery company.
