HDD 4.0TB ha perdido 2 billones de sectores

Buenos días,

Tengo un disco de 4.0TB que despues de un apagado del servidor, al encenderlo me dice el sistema que tiene 5860577134 scetores en lugar de los 7814037168 que deberia de tener para darme la capacidad de 4TB(3.6TB reales despues del formateo), le he borrado todas las particiones , tanto MBR comno GPT, pero no he conseguido que vuelva a tener los sectores originales, podrian indicarme si hay algun método/herramienta para solventar este problema o tengo que abrir un RMA para el disco, adjunto el mensaje que me da el sistema.

Partition GUID code: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 (Microsoft basic data)
Partition unique GUID: E3B37AF5-398A-4F07-9803-E31A4276E9D5
First sector: 2048 (at 1024.0 KiB)
Last sector: 7814035455 (at 3.6 TiB)
Partition size: 7814033408 sectors (3.6 TiB)
Attribute flags: 0000000000000000
Partition name: ‘hdd4g’

Expert command (? for help): v

Caution: The CRC for the backup partition table is invalid. This table may
be corrupt. This program will automatically create a new backup partition
table when you save your partitions.

Problem: The secondary header’s self-pointer indicates that it doesn’t reside
at the end of the disk. If you’ve added a disk to a RAID array, use the ‘e’
option on the experts’ menu to adjust the secondary header’s and partition
table’s locations.

Problem: Disk is too small to hold all the data!
(Disk size is 5860577134 sectors, needs to be 7814037168 sectors.)
The ‘e’ option on the experts’ menu may fix this problem.

Problem: GPT claims the disk is larger than it is! (Claimed last usable
sector is 7814037134, but backup header is at
7814037167 and disk size is 5860577134 sectors.
The ‘e’ option on the experts’ menu will probably fix this problem

Problem: partition 1 is too big for the disk.

Gracias por adelantado.
