I want to use my 1TB Hard disk in ubuntu. I have dual-booted Windows And Ubuntu. I can't see D in Ubuntu, in disks it says unmounted. I'm booting from SSD(C:)

  • D is a Windows construct. What is it your are seeing in Disks? Suggest you Google how to mount a hard disk in Ubuntu. – David Nov 05 '22 at 11:05
  • /dev/sdb4 1323008 1953521663 1952198656 930.9G Microsoft basic data Thats what i saw. Im using C for dual boot as well. But i want to use both hard disks like Windows. Its not D actually F i remember. Its a streotype of D thats why i mentioned like that

    sudo mount /dev/sdb4 /storage -- when i try this (found on google) not allowed:

    Mount is denied because the NTFS volume is already exclusively opened. The volume may be already mounted, or another software may use it which could be identified for example by the help of the 'fuser' command.

  • Drive letters only mean something in Windows not in in Ubuntu. How is the second drive formatted NTFS or something else? – David Nov 05 '22 at 11:38
  • What version of Ubuntu are you using? In Windows did you turn off fast boot? – David Nov 05 '22 at 11:40
  • In Disks, click the little triangle, if it turns to a square your "D", (sdb), partition is mounted – C.S.Cameron Nov 05 '22 at 13:25
  • @David: Idk how its gone NTFS i have 1 SSD and 1 hard disk. Ubuntu 22 im using i just installed it. Fast boot enabled i remember but his has second option i did not clearly remember. But i can look at it if needed. And Cameron: when i select D part in disks, its square allready – Oven Kravecki Nov 05 '22 at 13:36
  • Better to label partition so then it says music or photos or whatever it is. Much better than being stuck with d:. You can use gparted, disks (gnome disks) or command line. https://askubuntu.com/questions/147319/how-can-i-give-other-drives-and-partitions-short-meaningful-names-in-nautilus You can see labels: lsblk -f And then when mounted they will use that label. Better still if internal drive to create mount point & add to fstab to always mounted when you reboot. ` – oldfred Nov 05 '22 at 14:18

The "disk D" letter you see in Windows isn't a consistent naming. For example, if your "disk D" has another Windows installation and then you boot it, you'll see that your D became C, and the former C turned into D. If you unplug D and plug in a new one, it will become the new D. Etc.

Another thing to note: "disk D" is actually a partition, not a disk.

Linux has similar concept: there are disks /dev/sda, /dev/sdb, etc; and then they have partitions sda1, sda2, sda3, etc. Similarly to those in Windows, their names may change, depending on circumstances.

So you need to figure out which disk currently refers to the HDD you wanted (spoiler: if you only have two devices, and your "disk C" has a Linux installation as well, then most likely the "disk D" would be sdb, and its partitions are sdb1, sdb2, etc).

You may do that by looking for your disk implicit or explicit properties. Such as: the disk size — if you only have one disk of certain size, then you know which one you wanted to use. Or by partitions layout. Or by data in those partitions.

Or just execute lsscsi, which will show you the model names of the disks, so you can figure out which one you want. For example:

 λ lsscsi
[0:0:0:0]    disk    ATA      Netac SSD 1TB    XKR   /dev/sda
[1:0:0:0]    cd/dvd  PLDS     DVD+-RW DU-8A5LH 6D11  /dev/sr0

  • I know his name for sdb4 but in the output of lsscsi it calls sdb – Oven Kravecki Nov 05 '22 at 13:39
  • @OvenKravecki right, the sdb is a disk name, and then sdb1, sdb2, sdb3, sdb4 are all partitions. I omitted that part in my answer because I presumed that identifying the disk is enough for you, but to eliminate your confusion let me clarify: in WIndows the "disk D" is really not a disk but a partition. So yeah, you want a sdbX with X being a number, if you want, for example, to retrieve data that is on that "disk D", or whatever you want to do with it. – Hi-Angel Nov 05 '22 at 13:53
  • @OvenKravecki I added a clarification to my post, hopefully now it answers your question. – Hi-Angel Nov 05 '22 at 13:58
