Question New drive not recognized

[mstratil]

I recently purchased a 12 TB internal drive for my Windows 10 computer:


Seagate IronWolf 12TB NAS Internal Hard Drive HDD – 3.5 Inch SATA 6Gb/s 7200 RPM 256MB Cache for RAID Network Attached Storage – Frustration Free Packaging (ST12000VNZ008)

Immediately after I connected it, I was asked to select which format option I wanted. By mistake, I selected one for large drives; it said not all OS will recognize it.

Now I cannot find the drive in disk management. I have tried connecting it directly to the MB through cables, through my NAS, and through a USB case. Even though I can feel it spinning, nothing shows up.

So what can I do to recover from this problem?

So you initialized the drive GPT? This should be the correct partition table for this drive in Windows 10. Did you format a new partition NTFS? If for whatever reason disk management cannot find the drive, what about diskpart in the command line? Or check in your BIOS setup, to see if it is still found at all. There is a chance the drive is faulty and died somehow during initialization.

Thanks for your help.
1. I have done nothing but select the GPT option. I did not actually initialize it.
2. I have found DISKPART, and the drive appears there (as 16 TB!).
3. But I don't know what to do next.
4. You state that GPT is the correct partition table, but my other large drives are under NTSF. Please clarify.

GPT

Allows for 2TB+
MBR only does up to 2TB

Format as desired.

Success. I have fiddled with diskpart until I finally got the problem solved. Had to CLEAN the disk. Thanks for your help.

I suspect that your USB enclosure is configured with a sector size of 4096 bytes. That might be something to keep in mind if you intend to transfer data between computers.
