The WD hard disk worked perfectly with Time Machine, for about 2 years, until I upgraded to Monterey. I'm now erase and formatting the drive to Mac OS Extended (Journaled). But I'm pondering on the scheme to use, the Guide Partition Map leaves 850GB of the 2TB used, and I cannot see where the 850GB is !

I have used multiple WD external My Passport drives with Monterey for Time Machine. Make sure you uninstall any WD drive utilities or similar software you might have installed. In Disk Utility, select View => Show All Devices. Erase the physical drive entirely, at the highest level, specify APFS and GUID. After erasing it should be empty.

Thanks. I used disk utility to Erase the drive at the 2nd level and this took 5 hours. I had only 2 choices Mac OS ExtendedCase Sensitive with or without Journaled. I chose the with Journaled and it turned out OK and am now using the drive with Time Machine. Note I have a Buffalo hard drive and looking at the possibilities with erase I had 4 choices of APFS which did not appear on the WD drive. Not really happy with the situation so I purchased a Seagate 2TB UltraTouch and erased that with the APFS option. That seems to be working fine as well. Again Thanks for the help. Mick.
