    Hi @haggis999 ,
    I am inclined to think that your system does not support larger than 2TB drives. You may contact DELL support to confirm ( I may be wrong) and discuss the issue. They should be knowing better than anyone of us here.

    As I posted here yesterday, I have also reached the conclusion that my workstation does not support drives over 2TB. I am too busy at the moment, but when I get some free time I am planning to check this assumption with Dell.

    Thanks for the suggestion. I downloaded SeaTools for Windows, which listed my new disk as 2TB rather than 4TB. That wasn't much of a surprise, but what was unexpected was the indication that all three of my data disks are connected as SAS drives. Only the SSD used as my system disk is listed as a SATA drive. I never knew that I was using the SAS interface in my Dell workstation. Clearly, I need to have another read of the Dell user manual!

    However, this does suggest another possible reason for my machine's inability to recognise disks over 2TB. The MPTBIOS that controls the Dell SAS Adapter has not been updated since 2008.
