Considering how many people use multiple devices, often from different manufacturers, a comprehensive backup solution that works across multiple platforms provides the greatest level of security. While each device offers some kind of primitive backup option, they can be unreliable, slow and difficult to retrieve. That means an undelete utility can probably retrieve your lost data, as long as that section of the drive has not been overwritten.Īgain, the best way to avoid losing your data is by creating a backup. They do not use TRIM because they rely on the “marker” or “pointer” filing system described above. Traditional hard disk drives (HDD) also operate differently than internal solid state drives. The good news is TRIM is only utilized in internal solid state drives, so if your file was on a USB flash drive, SD card, external SSD, or another kind of solid-state storage, you can likely use a file recovery program to restore the lost file. If you use an internal solid state drive, the importance of regularly backing up your files can’t be overstated. That’s because an internal SSD runs an optimization protocol called TRIM that immediately clears that section of memory when a file is deleted. If your file was deleted from your computer’s internal solid state drive (SSD), it is unlikely that you can recover a deleted file. How you recover files in those instances depends on the hardware involved. Occasionally you hear stories of someone who has inadvertently formatted their computer drive or deleted a folder from a USB drive that contained files they still wanted.
