As a video editor or Digital Imaging Technician, you will often need to share files with others. Eventually you will find out that you may not be working on the same operating system (OS) as others. If you work solely on a Mac, but need to send files to someone working on a PC, your external hard drive needs to be set up for both operating systems. Let’s take a look at the different types of formats, and which are best for video production.

How to Convert a Mac-Formatted Drive to a Windows Drive Chris Hoffman @chrisbhoffman Updated July 10, 2017, 10:23pm EDT Macs format drives with Apple’s HFS+ file system, which Windows won’t recognize or access without third-party software. An external hard drive is a data storage device that connects to a computer with a cable, typically USB or FireWire. Most external hard drives are cross-platform, giving them the ability to work on a number of different operating systems. Macintosh computers are able to recognize hard drives formatted for both Macintosh and Windows computers.

Formatting the Hard Drive

A vast majority of video production will be done on a Mac or Windows operating system, so we aren’t going to cover Linux. Hard drives set up for use on Windows machines only will often use NTFS, while Macs will use HFS+. That said, if you are using both a PC and Mac in the workflow, you’ll need to use a different format.

You may be using only Macs or PCs in your own office, but you will also need to take into account what type of machines your client is using. If you need to send them RAW files or an edited sequence, you will need to make sure the external hard drive is set up for both operating systems. To do this, you will need to use either exFAT or FAT32 formats. This will allow you to use the hard drive on both a Mac and PC.

FAT32 is often used among general users, but FAT32 has limitations that can affect filmmakers. FAT32 has a maximum file size of 4 GB per file. The limitation affects both Mac and PC users. A single high resolution file can easily go over 4 GB, so Fat32 may not the best format. The best format for video production is exFAT. The maximum individual file size for exFAT is 16 EB. 1 EB, or exabyte, is 1 billion GB. That said, if you are using smaller file sizes — FAT32 can suffice.

Naming and Labelling Hard Drives

If you will be using multiple external hard drives on a project, you’ll want to make sure to keep them organized. This includes the way you name the drive and how you label it.

One of my personal tricks is naming all drives after an actor. For instance, one project had several external drives, all of which were named after different Will Ferrell characters — Mugatu, Megamind, Lord Business, and Ron Burgundy. Another project used Tom Hanks characters — Forrest and Woody.

Remember that external drives should be used temporarily — and all footage should be backed up elsewhere. Use checksum verification to make sure everything is copied correctly.

There are plenty of ways you can label your drives. You can simply use some masking tape or gaff tape, and then write the name of the drive. You can also use hard drive labels, which are the awesome stickers featured above. You easily put them on your external drive to keep track of them.

If you are a parent, like myself, you can also use any stickers you have lying around the house. I recently had Kermit the Frog and Optimus Prime hard drives.

No matter how you label your hard drives, just make sure you keep track of them. You never know when you will need that footage from a three-year-old project.

Two ways to format the external hard drive with multiple partitions

Users may want to reformat an external hard drive with multiple partitions so that they can keep only one partition on the disk for different purposes. And, there are two ways from which you can choose to manage the job. Here, I believe you may have a different choice in different situations.

1. Format external hard drive with multiple partitions using disk management

Removing partitions from the external hard drive and creating a new one is the first way you can try! It can be done with ease using disk management without any third-party software.

1) Connect the external hard drive to a Windows PC.
2) Press 'Windows+R' to open Run, type diskmgmt.msc in the empty box and tap 'OK' to open disk management tool.
3) Right-click the drive and click 'Delete Volume'.
4) Right-click the external drive again and select 'New Partition'. Finally, follow the wizard to finish the process.

As you can see, it will erase all your data from the external hard drive. So, you’d better not try this way if you have a large number of important data to be saved. And as an alternative, we recommend you to try a third-party partition software to merge multiple partitions into a single partition.

2. Format external hard drive with multiple partitions using EaseUS partition tool

EaseUS partition software is an excellent tool that works well to partition an external hard drive. It can help you reformat multi-partition external hard drive into one partition by combining partitions. What’s the most important, no data loss problem will occur during the process!

Step 1: Launch EaseUS Partition Master, right-click the partition on your external hard drive/USB/SD card which you want to format and choose the 'Format' option.

Step 2: Assign a new partition label, file system (NTFS/FAT32/EXT2/EXT3), and cluster size to the selected partition, then click 'OK'.

Step 3: In the Warning window, click 'OK' to continue.

Step 4: Click the 'Execute Operation' button in the top-left corner to review the changes, then click 'Apply' to start formatting your external hard drive/USB/SD card.
