A Brief Introduction to CFast Card
What Is a CFast Card
CFast card (CompactFast) is a high-speed memory card mainly used in professional photography and video equipment, especially in scenarios that require high data transfer rates, such as shooting 4K or higher resolution videos. The following are the core features of the CFast card to help you better understand it.
- Interface type: Adopts SATA interface (similar to computer hard disk), which is faster and more stable than the parallel interface of traditional CF cards.
- Read and write speed: The read and write speed can reach more than 500MB/s, far exceeding the traditional CF card (about 160MB/s).
- Application scenario: Widely used in high-end cameras, such as ARRi, Blackmagic, Canon EOS-1DX Mark II, etc.
- Appearance size: The appearance is similar to traditional CF card, but the interface is different and cannot be used interchangeably.
- Stability: Suitable for long-term, high-intensity data writing, making it ideal for professional video production.
Differences Between CFast and CF Cards
The CFast card came into being in 2008. It inherited the size and some naming of the CF card, but it was completely innovated in technical architecture, using a more advanced SATA interface, greatly improving the reading and writing speed and stability. The following are the differences between it and CF card.
- Interface type: CF card uses parallel ATA (PATA); CFast card uses serial ATA (SATA).
- Maximum speed: CF card is about 160MB/S; CFast card can reach 500MB/s or even higher.
- Usage scenario: CF card is suitable for ordinary digital cameras and industrial equipment, while CFast card is suitable for professional cameras and 4K/8K video recording equipment.
- Compatibility: CFast and CF are not compatible with each other.
- Price: CF cards are relatively cheap, while CFast cards are more expensive and suitable for high-end devices.
Can you Recover Lost Files From a CFast Card
Although CFast cards are fast and powerful, data loss can still occur in high-intensity use environments. If you have also experienced CFast card data loss, don’t panic. The lost data is possible to recover, but the success rate depends on the cause of data loss, how the card was used after the file loss, and the timeliness of your measures.
When data loss occurs on a CFast card, immediate response is crucial. Correct operation can significantly increase the success rate of data recovery. Here are the steps you should take immediately:
- Stop using the CFast card immediately. Do not shoot, record, or write any data to prevent new data from overwriting the original content. Do not format or repair the card, even if the device prompts you to do so. Do not try to copy files to avoid triggering write operations.
- Determine the type of data loss and take immediate action. If data loss is caused by human error or logical corruption, the following methods can help recover lost CFast data. For physical damage, recovery is unlikely unless you have a backup.
How to Perform a CFast Card Data Recovery
To perform a CFast card data recovery, you can follow the steps below. You can use several methods to do CFast card data recovery. These include using the Command Prompt to unhide files, restoring data from backups, or trying professional data recovery software and services.
Way 1: Use Command Prompt
Before performing CFast memory card data recovery, it is worthwhile to check if the files are hidden, especially if you suspect that the files have not been actually deleted or formatted. This action is simple and risk-free, but it has the potential to directly recover the files, saving the time and cost of using recovery software.
Step 1: Type Command Prompt in the Windows search bar, right-click the best match, and choose Run as administrator.
Step 2: Enter attrib -h -r -s /s /d G:\*.* in the window and press Enter.
- -h: cancels the hidden attribute
- -r: cancels the read-only attribute
- -s: cancels the system file attribute
- /s means including subdirectories, /d means including folders
- G:\ is the drive you want to process

After execution, the originally hidden files may reappear in the File Explorer.
Way 2: Restore Files From Backups
If the above command does not work, it means that the file may be lost. At this time, you need to retrieve files from a CFast card using other recovery methods. If you have a backup habit, then restoring your files will be much easier.
