Western Digital Hard Disk - Capacity: 16TB - Model: WD160EMFZ - Interface: SATA 6Gb/s This item was purchased used. It was a completely non-functional item that could not be recognized by a PC. The previous seller's comment stated, "It was working fine until it was removed, but I haven't confirmed its operation at this time," which is why I purchased it. ○ Although it can be mounted in an external case, a "Naked Capsule Hotel" enclosure, and Windows: - It cannot be initialized, and an error occurs when attempting to do so. - The volume is not displayed, showing 0GB. - Even trying to initialize it with diskpart → clean in the command prompt results in an error, preventing further progress. - No unusual noises, and it is spinning. The situation was as described above. I took it to a repair shop, and they said that there were various possible causes, making it impossible to pinpoint the issue, and that it was unusable. Is there anyone who can repair and use it? Please understand that this is a completely non-functional item before purchasing. Please note that returns and refunds are not accepted for completely non-functional items.
