mount - CDROM drive suddenly not recognised - Ask Ubuntu


[xubuntu 16.10] ripping cd in banshee , froze half way through. restarted banshee , didn't recognise cd, thunar no longer showing drive. read number of questions on here don't seem have done anything:

sudo lshw shows:

 *-scsi:3       physical id: 5       logical name: scsi7       capabilities: emulated     *-cdrom          description: scsi cd-rom          physical id: 0.0.0          bus info: scsi@7:0.0.0          logical name: /dev/cdrom          logical name: /dev/sr0          capabilities: audio          configuration: status=open

status doesn't change whether there's cd in drive or not or platter open.

i created folder: /media/cdrom and tried:

sudo mount /dev/sr0 /media/cdrom

but get: mount: no medium found on /dev/sr0

i added fstab:

/dev/sr0   /media/cdrom   udf,iso9660   user,noauto,exec,utf8   0   0

and rebooted nothing changed. super weird. thoughts? haven't tried changing sata cables yet, don't think have spare ports. in advance!

edit: drive seems intermittently recognised bios during boot. recognised in boot cycle lshw no longer lists it. sounds hardware buggy right?

edit2: changed free sata, on raid isn't. lshw says:

 *-scsi:2       physical id: 3       logical name: scsi2       capabilities: emulated     *-cdrom          description: dvd-ram writer          product: bd-re  ggw-h20l          vendor: hl-dt-st          physical id: 0.0.0          bus info: scsi@2:0.0.0          logical name: /dev/cdrom          logical name: /dev/cdrw          logical name: /dev/dvd          logical name: /dev/dvdrw          logical name: /dev/sr0          version: yl05          capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram          configuration: ansiversion=5 status=nodisc

now in /dev/ have cdrom, cdrw, dvd, dvdrw, link sr0 retried fstab line & mount no improvement, not listed. in thunar roof see cdrom clicking gives:

mount: /dev/sr0 write-protected, mounting read-only mount: no medium found on /dev/sr0

but putting cd in might have made work. testing now.

seems thing after upgrading: went 16.04 16.10 , had switch sata ports , edit fstab. irritante.
