Just bought two 4tb HGST drives and they show as 1.6tb in the disk management. They aren't formatted or partitioned that's just the total unallocated available space. I googled a bit and did convert them from mbr to gpt. Still a no go. they only show as 1.6tb.
my external usb 4tb drive works fine. internal 1 and 2tb drives show up fine as well.
board x8dth-if
os drives two regular ssd's in raid 0
windows 7 64bit
you can try to plug them in from usb, try different ports, disconnect some other drives, try 1 at the time.
this also could be some saved raid setup that existed on that board in past.
these are sata not usb.
as far as i can see my raid setup is the only saved one in the raid utility on the board.
obviously they are not usb... get a sata->usb plugs or unscrew your current usb drive and you can use that case as your sata->usb conversion.
other than that, its quite the possibility your bios doesn't support disks over 4TB; so i recommend using another pc or even your own to split it in partitions
I think you can check in crystaldiskmark.
Otherwise, sides bios, check them in linux liveCD or the like.
Pretty sure it has to be GPT for more than 2TB to show in windows
the ich10r supports 4tb disks , and the issue isn't partitioning it's the total size.
are you running in legacy mode or uefi?
Windows 7 requires the drives are "initialised" in GPT, not sure if initialised means anything except for putting a GTP table on it. Drives can have more than one table on them though, so it might be worth making sure its initialised with only a GPT on it.
how should i check if it has more than one
i dont know
enter your bios, and look for boot mode.
to use gpt you need to be booting in uefi.
else you will need to divide the drive in partitions on different pc that supports uefi and gpt or from usb - and divide those drives on 2x 2tb partitions
this motherboard doesn't seem to have a uefi option. however it supports 4tb drives
edit: after a quick google it seems to only apply to OS drive larger than 2tb needing uefi
update your bios, if it doesn't support uefi you won't be able to access total size of 4TB from a disk. You'll see them below 2TB. (same goes for drives with 3TB, you'll likely see them as 1.7TB)
you can still use whole thing if you partition the drive on 2TB partitions.
that seems to be consitant with os drives not added drives from what I'm seeing
Full system specs please. Sorry if it is in your profile on mobile that is a hassle to check.
Got sick of trying to figure it out so I just did this problem solved
