I purchased a hard drive which looks like a fake (doesn’t mount when I plug it in, the label is suspicious).

If there a way using terminal to know if it’s usable? Nothing mounts when I plug it in Disk Utility as seen in this screenshot.

The Terminal command returns this:

/dev/disk0 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *1.0 TB     disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                  Apple_HFS Macintosh HD            1.0 TB     disk0s2

    It's either a bad cable, a defective SSD, or a fake. Commented Feb 14 at 18:48

    You already know it's not useable :-) You could try a different computer, but if nothing works, return the SSD.

    So, the Mac doesn't see the device at all -> try different port, different cable, different computer. If nothing helps, return it.

    Honestly, the name alone (and the lack of any actual brand) shouts „fake“ (probably made to look like this). Sorry about that.

Opening it up should let you see the circuit board and if it’s just parts and a cheap, small flash storage with firmware that intended to match the alleged size or if this is legit storage that has failed in some manner.

The label and branding present as suspicious to me. So if I had to guess, looks very counterfeit as it's trying to make you think it's a WD Blue SSD and the printing is very low budget. The case and connector are decent quality, but again, those are very inexpensive in bulk compared to a tested SSD NAND.

System profiler will enumerate the USB bus if that’s how you connect this as well as all SATA connections if you use that direct to the Mac. You should see those even if the storage layer like diskutil shows nothing.

That WWN should show to the sata controller, specifically.

system_profiler SPUSBDataType
system_profiler SPSerialATADataType
system_profiler SPStorageDataType

However, you can use a barcode scanning app like QRafter and see the first two barcodes scan as the exact same sequence - Code 128 representing 1Z123X5603123458. The third doesn’t scan due to the fold I presume, but they all are the same barcode. So, someone didn’t even generate matching barcodes for the serial number, model number and WWN but manipulated the same image to alter the scale of each.

Code 128 barcode of 1Z123X5603123458
