Question hdd not recognising

[Scotch Egg 71]

I have set up an old pc as a media server with linux server and everything works great, I have a WD 18 tb sata hdd from a my book external enclosure but the bios will not recognise it when attached as sata.
The motherboard is an ASUS P6X58D-E

I have found out why, its the 3rd pin on the power connector needs to be masked off.

Be aware that My Books are encrypted, so your OS may not recognise any partitions when you install the drive inside your computer.

It's fine everything worked as soon as i masked the 3rd pin off.

Several factors could be causing this issue with your WD 18TB HDD not being recognized in the BIOS of your ASUS P6X58D-E motherboard:

1. BIOS limitations: Older motherboards often have BIOS limitations on maximum drive capacity. Your P6X58D-E is quite old and may not support drives larger than 2TB or 4TB.
2. Firmware: The drive may need firmware designed for internal use, as it came from an external enclosure.
3. Advanced Format: The drive likely uses Advanced Format (4Kn), which older systems might not support.
4. SATA controller: Your motherboard's SATA controller may not be compatible with newer, large-capacity drives.

Possible solutions:

1. Update BIOS: Check if a BIOS update is available for your motherboard that adds support for larger drives.
2. Use a SATA controller card: Install a modern SATA controller PCIe card that supports large drives.
3. Partition the drive: Create a smaller partition (< 2TB) at the beginning of the drive. The BIOS might then recognize this partition.
4. Use software workarounds: If Linux recognizes the drive, you might be able to use it even if the BIOS doesn't see it.
5. Use the drive externally: Connect it via USB if the internal SATA connection isn't working.
