Certain files consistently not being read from DVD
I have been running into a problem when trying to copy dicom files (from an MRI scanner) off of DVD to our computer running RHEL 5.3. Within each folder, the 12th, 27th and then every 14th file after that are not showing up when I browse the disc. Additionally, some folders themselves are not present. Trying ls -a and viewing hidden files doesn't seem to help. However, these files ARE on the dvd as I can view them on a PC and Mac. When transferred from dvd to usb drive on these computers, I am able to load them onto the linux machine.
There doesn't seem to be any reason why these files should be treated differently as each one should contain very similar data. Any ideas would be much appreciated, let me know if I should provide more info though.
Thanks for your help,
