Ubuntu cannot detect a partition but Windows can detect it

pl flag

I currently have dual boot on an SSD. Earlier I had a dual boot on my HDD. One of the partitions in the HDD is now not accessible to me when I boot from Ubuntu on the SSD. It cannot detect the partition. However, when I boot Windows from the same SSD, it can still detect the HDD partition.

Output of lsblk

Was Ubuntu OS installed on the HDD? And assuming the SSD is a new addition, did you perform a new Ubuntu OS installation on the SSD?

@darth_epoxy Yes, Initially Ubuntu OS was installed on HDD. The SSD is a new addition. Now, new Ubuntu OS is installed on the SSD.

If you cannot mount it manually, try running `gparted` and check the permissions on that drive / partition. BE CAREFUL this tool does not ask twice so don't go formatting or deleting anything!

@darth_epoxy how to check the permissions on that drive. I opened the gparted but cannot find permissions option.

Ah sorry, you have to go to View then File System Support. but ... now that I do this myself it appears you are right and it will not actually change them, just display them. If it has read and wrote permissions, then you just need to figure out how to mount it.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
