From Wikipedia :
CompactFlash: CompactFlash (CF) was originally developed as a type of data storage device used in portable electronic devices. For storage, CompactFlash typically uses flash memory in a standardized enclosure. This form was first specified and produced by SanDisk in 1994. The physical format is now used for a variety of devices.

The best advice is to do frequent backups.
If you have a recent backup of your data, you can rest easy.
If/when your hard drive fails, it is not a crisis since you have safe copies
of all of your important data.
Don't ever try to disassemble your hard drive. What do you expect to find in there? No. More than likely, you will break something and certainly you will contaminate your drive with small particles and make data recovery more difficult or impossible. We won't open your drive and neither should you. Only facilities that have a cleanroom should consider opening a hard drive.
Don't hit the drive. Don't bang it, don't beat it, don't whack it, don't drop it. Perhaps you have experience where that helps something but it will only hurt your drive.
If your hard drive starts making noises, don't wait. Shut it down and have the data recovered right away. The more you use the computer, the worse the hard drive will deteriorate. Over time, recovery may become impossible.
If your system crashes and you have a recovery disk, you might be inclined to use it to bring your system back to life. This very well may be successful, but often these discs will re-image the drive which wipes out all of your data. This puts the system back to a from-the-factory state which is before you put your files on it. Back up your files before doing a reinstall or re-image or a system restore.

Don't use USB flash drives as primary storage when you can avoid it. USB flash drives (pen drives, thumb drives, pocket drives) can be very convenient. They can also die without warning. When you can, use them only to transport copies of data and not the only copy. It is best to copy files to the USB flash drive. That way, if the flash drive is damaged or lost, you still have another copy on the hard drive of a computer or two.
Backing up your data helps you prepare for a data disaster. But what if the disaster involves a fire, tornado, or some other event that destroys your home or workplace? If your backups are stored there, then they might be destroyed along with the computer they are designed to protect. Consider storing your backups off-site. Whether that means carrying a copy with you in a USB drive or storing files remotely over the Internet, it can make all the difference.
