If you’ve ever had a memory card either go bad or become unreadable, you know how frustrating that can be. However, all is not lost. With a bit of work you can recover that data. Let’s find out how.
What is CompactFlash?
CompactFlash (aka CF) memory is a type of non-volatile, solid-state memory used by many portable devices (such as cameras and camcorders). This type of memory has been around since 1994 (originally created by SanDisk) and has become so widespread that its usage has surpassed traditional storage devices (such as harddrives).
CompactFlash cards are larger than SD and microSD cards. A typical CF card measures 42.8 mm by 36.4 mm and can range from 512MB to 128GB of storage. Other than size, the biggest difference between CF and SD cards is speed and cost. CF cards are more expensive than SD cards, but are also considerably faster and more durable. Most compact flash cards display the minimum write speed directly on the front in the form of X MB/s (Where X is a number to indicate the write speed in MB per second a card can handle).
For comparison, the average write speed of an SD card is approximately 12.5MB/second.
Although most devices have migrated to SD and microSD cards, there is still plenty of technology out there that requires CF cards. You’ll find these cards in commercial-grade video cameras, where write speeds that are faster than typical SD cards can handle.
Why You Need CF Card Recovery
Someday you might find yourself in a situation where a CF card has data that your computer cannot retrieve. And because that card was probably used in a camera or camcorder, you will definitely want those files.
But what can happen to a CF card to cause the data to become unreadable? There are a few reasons this can happen.
- You’ve accidentally deleted files: This happens more often than you might think, and can occur on the device that uses the card or your computer.
- Card formatting: You might have accidentally reformatted a card that contained files you still need.
- File system errors: The file system on the CF card can become unstable or unreadable by your computer.
- Virus attacks: A virus has rendered your card unreadable.
- Corrupted/damaged CF card: The partition table on the CF card might have become unrecognizable by your computer operating system, or you have a physically damaged card.
- Power surge or outage: If there’s a power surge as your computer is trying to read the CF card, it can become damaged.
- Water damage: Water is the enemy of electronics.
- Physical damage: You might have bent or even broken your CF card.
How to Recover Files from CF Cards Using Recovery Software
If you happen to have a CF card that contains data you cannot access, all is not lost. One of the best options to retrieve that data is by making use of a third-party memory card recovery software solution. There are quite a large number of applications available for this purpose, one of which is Disk Drill, which supports all brands of CF cards and can recover nearly any type of file. You can use Disk Drill free (500MB recovery for free), or purchase a Pro license for $89.00.
Let’s dive in and find out how to recover files from a CF card that’s unreadable by your computer.
- Download and install Disk Drill compact flash card recovery software.
- Insert the CF card into your PC or laptop (you might need to use a CF card reader for this).
- Open Disk Drill and click on the entry for the Generic STORAGE DEVICE USB Device associated with the damaged or unrecognized CF card.
- From the drop-down in the right sidebar, select All recovery methods and then click Search for lost data.
- At this point, you must allow Disk Drill to completely finish the CF card scan. If you pause or stop the scan before completion, the chances of complete data recovery are reduced. Depending on how large the CF card is, how much data is/was on the card, and the speed of your computer, this scan could take some time. You should also know that if the CF card was accidentally reformatted, Disk Drill will first search for and recover any lost partition on the card (adding even more time to the scan).
- When the scan completes, if you find Disk Drill didn’t locate the number of files you expected to recover, click Scan entire disk (if available) and allow the tool to run a full scan of the CF card. If, however, it does locate the files you expect, click Review found items.
- Expand each entry, under either Deep Scan, Reconstructed, or Reconstructed labeled. Keep expanding until you find the recovered files you’re looking for. One thing you should make sure to do is to right-click the item in question and select Preview (or hover over the file listing and click the eye icon) before you select each item to recover. If the file preview appears as you expect, click the associated checkbox for the file. Continue previewing and selecting the recovered files until you have all of them checked.
- Click Recover.
- When prompted, select a location to house the recovered files. Make sure you do not select a destination that is on the same drive as the one you are recovering from.
- Click OK and Disk Drill will recover the found files to the selected destination.
Congratulations, you’ve successfully recovered files from a broken or unreadable CF card.
How to Recover CF Card with Data Recovery Service
If you find that the software recovery method did not work for you, all is not lost. You can opt to use a data recovery service that has very powerful tools to recover data from CF cards that consumer software would never find. Data recovery specialists are remarkable at salvaging data, even from CD cards (or other devices) that are too far gone for consumer software to save.
CleverFiles offers such a service. If you have a CF card that Disk Drill (or another solution) cannot save, reach out to them (or another company) so they can recover your lost files.

PhotoRec is a freeware tool that supports a wide range of storage devices like CF cards and runs on many different operating systems including Mac and Windows. It does not possess the features or user-friendly interface of commercial data recovery solutions. Users need to interact with a command-line interface and supply recovery details such as partition names that may be beyond the scope of their computer knowledge.
Files are recovered under generic filenames which require users to preview them to identify their contents and rename them more descriptively. This makes the tool less efficient, especially when attempting to recover a large number of files. If you are prepared to use a command-line and are performing a limited recovery, PhotoRec could be the right tool for the job.
- Freeware with no cost to the user
- Supports data recovery from Mac, Windows, and Linux machines

How to Improve the Chances of Recovery
To begin with, you should not leave this process to any software that isn’t specifically designed for data recovery. By doing that, you could lessen the likelihood that Disk Drill (or any other tool) could recover those files.
You should also not reformat the card. When you insert a CF card into a computer, and the computer has trouble reading the card, it might prompt you to reformat. Don’t. Yet another formatting could lessen the chance of recovery.
Also, do not attempt to write data to the card in question. By doing this you could overwrite or destroy the data you want to actually recover.
How to Prevent Data Loss on a CF Card
It should go without saying that you should care for these cards. Store them in protective cases and never leave them in extreme heat or cold.
You should also always remember to safely eject your cards from the computer. Do not just pull the card out when you’re done. By doing so you risk corrupting the card’s partition table, making it unreadable by your operating system.
Finally, always backup your CF cards. With a recent backup, even if something does happen to the card, you still have copies of your files and won’t have to worry about data recovery.
Hopefully you’ll never have to recover data from a corrupt or broken CompactFlash card. But when the time comes that you do, rest assured you can use tools like Disk Drill to recover CF card data loss. Whether it’s spreadsheets, documents or you need to recover photos from a CF card, tools like Disk Drill have you covered.
