Hello, I've a very old slide positive (a framed picture of 24x36mm). A local drugstore scanned the picture and returned me disk, a CD or DVD. But I can't mount it as cd9660 file system. The only thing I can do is: # grep cd0 /var/log/message Nov 13 12:01:35 e6330-r314251 kernel: cd0 at ahcich1 bus 0 scbus1 target 0 lun 0 Nov 13 12:01:35 e6330-r314251 kernel: cd0: <PLDS DVD+-RW DU-8A5HH SD11> Removable CD-ROM SCSI device Nov 13 12:01:35 e6330-r314251 kernel: cd0: Serial Number TTYK05508134O47P3A01 Nov 13 12:01:35 e6330-r314251 kernel: cd0: 150.000MB/s transfers (SATA 1.x, UDMA5, ATAPI 12bytes, PIO 8192bytes) Nov 13 12:01:35 e6330-r314251 kernel: cd0: 13MB (7086 2048 byte sectors) # cat /dev/cd0 > cd0 # ls -l cd0 -rw-r--r-- 1 root wheel 14512128 13 nov. 11:18 cd0 # file cd0 cd0: data # strings cd0 | more BEA01 NSR02 TEA01 3256792369 4A8508F400000FB8 OSTA Compressed Unicode OSTA Compressed Unicode *EPSON Disc Library UDF *UDF LV Info OSTA Compressed Unicode 3256792369 *EPSON Disc Library UDF +NSR02 *EPSON Disc Library UDF OSTA Compressed Unicode 3256792369 *OSTA UDF Compliant *EPSON Disc Library UDF 3256792369 4A8508F400000FB8 OSTA Compressed Unicode OSTA Compressed Unicode ...
