System Model HP EliteOne 800 G1 Touch POS AiO
Microsoft Windows 10 (64-bit)

According to the HP website : https://support.hp.com/us-en/document/c03844827 : System Model HP EliteOne 800 G1 Touch POS AiO is compatible with Up to 1TB hard drive, 160GB SSD (Solid State Drive); up to 256GB self-encrypting solid state drive; 500 GB Self-encrypting Drive, or 1TB solid state hard drive. So I bought a WD Blue 2.5 solid state drive 3D NAND SATA SSD Solid State Drive. It fits the computer just wont read it. Put the old 128 GB and it works just fine. What is the largest Hard drive I can purchase for this HP Computer that will work? 128 GB's is not going to work.

The new drive, be it a SATA HDD or a SATA SSD,  generally came from the factory as a "raw" drive.  That is, unformatted and without partitioning pre-done for you.  So you need to do some prep work initially because it came not ready for prime time.

 

Since you are going to be using a Windows OS it is best to boot off of the original drive that was working fine, and use the built-in Disk Management software to do a MBR partitioning and then a NTFS long-type formatting to get it ready for Windows OS loading.  A computer shop can help if this is gibberish to you... which is fine.

 

If over 2.1GB in size use GPT partitioning instead.  Or just do GPT for all sizes.   EDIT:  Ooops... if the size of the drive, be it a HDD or a SSD, is over 2.1TB in size you'd want to use GPT partitioning, and then a long type NTFS format.  The reason I do the long type of NTFS formatting after the partitioning is done is because it is the long type that will map out defective sectors on the drive and the short type won't.
