Inconsistency in detecting cdrom

[since1991sanchit]

I inserted the cd-r in cdrom and it appears under Disks and Devices section in the tool bar. I can also see it in left panel in dolphin and browse the contents in the cd.
On running following commands the outputs are shown inline:

❯ blkid
/dev/sr0: BLOCK_SIZE="2048" UUID="2008-06-30-10-58-00-0" LABEL="Rudra Kawach" TYPE="iso9660"



❯ sudo lshw -c disk

But on subsequent inserts, the behavior is pretty inconsistent. Sometimes it is not detected by cdrom and won't appear in output of sudo lshw -c disk

Other times the disc is detected, but the block identification (blkid) shows nothing.

This inconsistent behavior is weird. Any clues what might be going wrong?
