Formatting a drive for Digital Cinema Packages (DCP) requires careful attention to ensure compatibility with digital cinema systems. Drives used for DCP usually need to be formatted with the Linux EXT2 or EXT3 filesystem to be recognized by most digital cinema servers. This article should guide you through formatting a drive with the EXT2 filesystem specifically for DCP distribution.

Step 1: Connect the Drive

Ensure that the drive intended for DCP is connected to your Linux system. This drive should be empty as formatting will erase all existing data.

Step 2: Identify the Drive

Use the lsblk command to list all connected block devices and identify your target drive:

bashCopy
lsblk

Look for the drive by its size and any other recognizable details, typically noted as /dev/sdb, /dev/sdc, etc.

Step 3: Unmount the Drive

If the drive is mounted, you need to unmount it before proceeding:

bashCopy
sudo umount /dev/sdb1

Ensure to replace /dev/sdb1 with the correct device identifier from the lsblk output.

Step 4: Create a New Partition Table

It's advisable to start with a clean partition table:

bashCopy
sudo fdisk /dev/sdb

• Type g to create a new GPT partition table (recommended for modern storage devices).
• Type n to create a new partition, then set the size or use defaults for a single partition.
• Type t and then 83 to set the type to Linux.
• Type w to write the changes and exit fdisk.

Step 5: Format the Partition as EXT2

Format the newly created partition with the EXT2 filesystem:

bashCopy
sudo mkfs.ext2 /dev/sdb1

Be sure to replace /dev/sdb1 with your partition.

Step 6: Mount the Filesystem

Create a mounting point and mount the filesystem:

bashCopy
sudo mkdir /mnt/dcpdrive
sudo mount /dev/sdb1 /mnt/dcpdrive

Step 7: Set Permissions and Ownership

Set the correct permissions and ownership to ensure that any DCP software can read and write to the drive:

bashCopy
sudo chown -R user:group /mnt/dcpdrive
sudo chmod -R 775 /mnt/dcpdrive

Replace user and group with the appropriate values.

Step 8: Add to /etc/fstab (Optional)

If you need the drive to be automatically mounted at boot:

bashCopy
echo '/dev/sdb1 /mnt/dcpdrive ext2 defaults 0 2' | sudo tee -a /etc/fstab

Step 9: Verify the Drive

Ensure the drive is properly formatted and ready for DCP use:

bashCopy
df -h /mnt/dcpdrive

Step 10: Transfer Your DCP

Now, you can transfer your Digital Cinema Packages to the drive. Use standard file transfer commands or GUI tools, ensuring the DCP structure is maintained.

Conclusion

This setup ensures that your drive is formatted correctly for DCP distribution, compatible with cinema servers. Always double-check your DCP files on the drive before delivering them to ensure they meet the required specifications and are free of corruption.
