Recovering Data From USB Flash Drives and SD Cards

In an earlier blog post, we talked about how you could get lost data back and mentioned a few products that could help you.

Of course, if you’d rather not risk doing it yourself, there are a number of companies you can find with a quick Google search that can do it for you for a small fee (usually starting at around £50).

Unintentional erasing or mistakenly overwriting data are only a couple of ways you could lose data. If you were unfortunate to fall into a swimming pool whilst working on your laptop (it could happen), or accidentally set it on fire, your data could still be retrievable.

Hard drives are pretty resilient and it usually takes a powerful magnet to be completely and irrevocably erased.

In the same way, flash drives can usually be recovered by knowledgeable computer users hence the large number of recovery tools. For data to be truly erased from a flash drive a third party cleaning tool is usually required.

How to protect your flash drive

Here are our top tips:

  • Frequently back up all important data to a service such as BullGuard Backup
  • Don’t use flash drives for frequently updated files. Flash has limitations compared to hard drives
  • Make sure you always remove flash media safely and never unplug the drive while it is reading or writing
  • Keep your flash drive stored in proper conditions and don’t expose it to extreme temperatures, humidity or pressure to keep it functioning longer

So, if you want to keep your data safe, don’t work near a swimming pool, keep away from naked flames and above all, think very carefully before deleting and saving documents.
