My external hard drive became noisy, and then at once became unable to mount. With hindsight, I could have acted on the slightly increased vibration from the drive before it failed. Tecleo recovered the majority of the files on my drive, which were family photos of sentimental value to us. It must have been a very tedious job, as it took much longer than expected. Tecleo along the way communicated professionally with us. Despite it taking much longer, they stood by their initial cost estimate."
