If a read is made to a removable media drive when no media is present, the read fails. A warning is written to the console and the log file. The warning will look similar to:
scsi: [ID 107833 kern.warning] WARNING: /pci@1f,0/pci@1,1/ide@3/sd@2,0 (sd30): i/o to invalid geometry |
The path that appears in the warning message is the device path for the removable media.
The warning is invalid. When media is missing from a removable drive, the read should fail silently.
Workaround: Ignore these warning messages in the case of removable media.
