I just installed ubuntu today so I dont really know much about unix/ubuntu, but I have a little problem.
2 years ago, I bought a pc with a 3tb internal hdd. I installed w7 (64bit), but I had an issue, basically i formatted the hdd as MBR (instead of GPT) and I could only see 2tb instead of 3tb. I read that to fix such problem asus had a tool (called disk unlocker https://event.asus.com/mb/2010/Disk_Unlocker/ ) that basically mounts a virtual drive containing the missing TB that windows couldnt see, so I used that.
Now the issue is that under ubuntu, of course, i only see the 2tb partition, the extra one (that windows can see only after running disk unlocker) appears as "free space".
Anyone know if theres a way to mount that missing partition under ubuntu?

One solution would be to format the hdd as gpt but I cant do that.

Thanks!

In answer to your question:

No.
GPT
Reformat it, and do it properly.

The MBR partition table only recognizes a 2.2TB volume. Period.
There is no magic way around that.

(well, there is some foolishness from (i think) WD to do this. But thats not what you want)

Well, theres a workaround for sure (i use diskunlocker because I have an asus, asrock has another program called 3tb unlocker, and im sure other mobos have one as well, they all probably do the same thing to see a 3tb hd under mbr) since ive been using it for 7+ years on others pcs before this one and always worked. I thought there was a way to do so in linux as well tho. I cant reformat that hdd, it has an installation of windows i might still need one day.

Anything can be redone but i dont want to reinstall that particular installation of windows tbh, would take too much time to redo it the way it is. And those workaround worked pretty well for 8 years so its not like theres a risk to lose data or anything, they work fine. And i'm sure there must be a way to make it work under linux as well, after all now everyone pretty much uses GPT but back when a lot of mobos didnt support it people had to use mbr, i cant belive people would just lose 33% of a 3tb hd switching to linux.
