4TB recognized on Linux, 1.8TB on BIOS

Recommended Posts

Posted · Original PosterOP

Hi, I'm currently building myself a server for bakcups with an old PC I had lying around. I have a brand new 4TB drive to use with it. I installed Ubuntu, urbackup and everything seems to be perfectly fine. Then I entered the BIOS for some reason and noticed that the disk appears as 1.8TB (normal in old BIOSes, right?). After seeing that, I'm wondering if I'm going to have issues when the disk tries to write past those 1.8TB that the BIOS sees. Ubuntu has no problem seeing the whole 4TB and allowed me to partition it without any problem, but I have doubts now that maybe it will behave like those fake 2TB HDD that are really microSD or something like that. Does anybody know how to test this, apart from filling the drive with more than 1.8TB (last resort), or can confirm that if linux sees the entire drive it doesn't matter what the BIOS is reporting?

Thanks in advance!

Legacy doesn't support drives larger than 2TB, you need UEFI

I technically knew that, but up until now, everytime I run into this limitation, the OS would also see the limited drive in the same way as the BIOS. Since I'm now seeing the entire drive in ubuntu, I was wondering if maybe there was some in-between moment when a BIOS could, for example, not boot from larger than 2TB drives, but could use them in it's entirety.

Thanks. I see no mention of linux there, but at least it confirms that through software there is a way to use 4TB on old MBR BIOS. Maybe linux just has a way of "cheating" around the limitations as well. I'll wait a bit more to see if someone can confirm this, else I think I'm just going to copy more than 1.8TB files there and see if it works.

That may be, but I'm using ubuntu 20.04 LTS, so if it works with this setup then that would be enough.
