How many disks will Windows 10 support?

Question

_{Wednesday, May 18, 2016 4:51 AM}

My home built, video editing computer has an ASRock X99 Extreme4 motherboard. I have a hard drive S: for storage of videos, an M: drive for music, a P: drive for pictures, an O: drive for overflow, an external B: drive for backup. I connected a 6th drive to Sata3_5 to be used for additional video storage, but it does not show up in disk management. Does Windows 10 support a 6th hard drive? What do I do to get the drive to show up in disk management so I can initialize and format it?

I'm not sure how, but I do now have the disk formatted and enabled. I phoned the ASRock support and they had me disconnect the 7TB Seagate external hard drive I was using for backup. I also looked in the UEFI and saw the disk was recognized there. I didn't change anything but when I went back to Disk Management it was recognize there and I initialized the 3TB internal drive, formatted it as a GPT drive with X: letter to signify eXtra video storage. I was then able to reconnect my external hard drive for backup and it is recognized also. I really don't understand what was wrong or how it got fixed. As best I can tell, there were no changes made to the system of the computer, I just put this in here in case there are others with similar problems and may know exactly what happened. Thanks to those who offered help.

I guess, its 4 primary disks / partitions. 

And you can have 128 secondary partitions / disks.

Under "Disk Management" I see five disks listed but I don't see a place for a sixth disk, and that is why I am wondering if Windows 10 does support 6 disks? Anyone have suggestions about how I should proceed to get my fifth disk recognized in Disk Management?

Well added 8 disks in Windows 10 all seen in Disk Management (the display gets bigger and makes the space). For info on a server seen over 40 disks listed in Disk Management (same technology base to me). Looking at Storage Spaces Frequently Asked Questions (FAQ) the only place I could find mentions of limits starts in 10's of disks (Windows 10 support Storage Spaces). So do not think the number of disk is the issue here.

So starting with is it showing in the BIOS?

Try from a command prompt 'diskpart' (without quotes), once open enter 'list disk', does that show any different?

Check your BIOS to make sure the disk is shown. Sometimes you need to enable the port there.
