I recently migrated my Ubuntu 20.04 LTS from HDD to an SSD. The previous ubuntu partition on HDD was 107 Gbytes. The SSD OS boots successfully but some how does not recognize the old HDD partitions. The HDD has partitions as follows in which sda1 being old boot and sda8 as old swap partition.
sda 8:0 0 465.8G 0 disk
├─sda1 8:1 0 106.7G 0 part /media/user/12a213e9-14aa-4b77-bf7c-77e89f242
├─sda2 8:2 0 1K 0 part
├─sda5 8:5 0 116.4G 0 part /media/user/7A9428429427FEEF
├─sda6 8:6 0 116.4G 0 part /media/user/98EA0A9DEA0A77B0
├─sda7 8:7 0 116.4G 0 part /media/user/26D81E7ED81E4C85
├─sda8 8:8 0 7.9G 0 part
└─sda9 8:9 0 1.9G 0 part
While migrating I also created swap on SSD. SSD partitions are as follows.
sdb 8:16 0 223.6G 0 disk
├─sdb1 8:17 0 213.8G 0 part /
├─sdb2 8:18 0 9.6G 0 part [SWAP]
└─sdb3 8:19 0 200M 0 part
While opening HDD partition, I am getting error an 'Could not display 12a213e9-14aa-4b77-bf7c-77e89f242. The file is of unknown type'. Is this happening due to wrong mounting of HDD?
cd /media/user/12a213e9-14aa-4b77-bf7c-77e89f242
will bring you into the mounted filesystem.
