Description (last modified by Quozl) (diff)

The primary volume descriptor is read from an incorrect media address, because the calculation of offset depends on the sector size of the device, in iso-9660? in the disk label package. This results in the filesystem not being detected.

ISO9660:1999 implies in section 6.1.2 that logical sector size should be at least 2048 bytes. The primary volume descriptor is at an offset of 16 logical sectors.

(However this temporarily prevents use of ISO-9660 images on USB optical drives).
