I played a bit with mount_udf, and I have a question (or a bug report ?). It worked from the technical view (mount_udf can mount an InCD disk made at work) and ls/cd can walk on fs but if a try to copy a file from CD to HD I obtain a 'correct' size file completely filled with NULLs. Only "cp" command seems to be affected, if I "cat" same file to HD it will be copied correctly, even if I view images with xv or use md5 or hd to compare them. Only cp differs... Is this a bug, a wanted design or a pilot error ? Here a little log to explain better: # mount -tudf /dev/acd0c /cdram # cd /cdram # ls -l IMG_0195.jpg -rwxrwxrwx 1 root wheel 99359 Apr 28 15:37 IMG_0195.jpg # hd IMG_0195.jpg | head -1 00000000 ff d8 ff e0 00 10 4a 46 49 46 00 01 00 01 00 96 |......JFIF......| # cp IMG_0195.jpg /tmp/foobar.jpg # md5 IMG_0195.jpg /tmp/foobar.jpg MD5 (IMG_0195.jpg) = a4a45affe7e37d55329a2b78a6199023 MD5 (/tmp/foobar.jpg) = 855f3a16b3fb31cba960e5e2820d959d # ls -l /tmp/foobar.jpg -rwxr-xr-x 1 riccardo wheel 99359 May 7 23:39 /tmp/foobar.jpg # hd /tmp/foobar.jpg 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00018410 # cat IMG_0195.jpg > /tmp/foobar.jpg # md5 /tmp/foobar.jpg MD5 (/tmp/foobar.jpg) = a4a45affe7e37d55329a2b78a6199023 # hd /tmp/foobar.jpg | head -1 00000000 ff d8 ff e0 00 10 4a 46 49 46 00 01 00 01 00 96 |......JFIF......| TIA, Riccardo.
