Recently Installed 6/six (QTY.) 22TB WD Gold Enterprise Class SATA HDDs for my EVGA Z270 FTW K MoBo PC, but it will only see 20TB out of 22TB for each of my HDDs; both in DOS RAID Setup upon boot-up/POST, & in Intel Rapid Storage Tech. RAID software program on Windows 10 OS.
Keep in mind that I'm NOT referring to AFTER initializing & Formatting 22TB HDDs, where storage space is lost in order to create NTFS & partition, but BEFORE doing so.
z270 MoBo does recognize HDDs as being 22TB BIOS; but DOS RAID Setup & Intel RST do NOT; only see them as being 20TB each.
OS is fully Up-To-Date; Successfully installed Updates from EVGA, including latest BIOS Update (1.09), latest Intel ME & Intel RST programs.
HDDs in question are: Western Digital 22TB WD Gold Enterprise Class SATA Internal Hard Drive HDD - 7200 RPM, SATA 6 Gb/s, 512 MB Cache, 3.5" - WD221KRYZ
Done everything I can think of so far, but my PC/MoBo z270 only sees them as being 20TB each. Has anyone else had this kind of similar problem? Any ideas? Please help me, if you might know how to resolve this. Thank you.
