My 1TB hard drive stopped working, and I contacted a technician for help. He insisted on taking the drive with him instead of working on it at my home, even though I offered to let him use my laptop. While sitting in his car, I watched him connect the drive to his laptop, open R-Studio, and then check Device Manager. I noticed one of my file names appeared in R-Studio. He did not visibly copy the entire drive, but I am worried he may have opened or saved some of our private family photos and folders. Could he have extracted files quickly without me noticing, or does seeing a file name in recovery software simply mean that the software was scanning or cataloging the drive?

A legitimate repair business generally has little to gain and a lot to lose by secretly viewing or keeping customer files. The normal diagnostic steps may involve removing the drive from its enclosure, connecting it directly, and using recovery software to determine whether the data can be read. Still, your privacy concern is reasonable. If the drive contains sensitive material, choose a technician you trust, stay present during the inspection when possible, or use a service that documents its handling and securely deletes temporary copies.
You may be able to attempt recovery yourself, but be careful: repeated scans or writing anything to the failing drive can make the situation worse. Do not format it, initialize it, or save recovered files back onto it. Ideally, create a sector-by-sector image first and work from the image, or have a professional do that. If the drive is clicking, repeatedly disconnecting, or not spinning properly, stop using it and seek a specialist. Once your files are recovered, make at least two backups in separate locations.
Technically, a technician could copy individual files if the drive was readable, and copying a few files can be quick. However, seeing a filename in R-Studio does not prove that anything was copied. R-Studio is commonly used to inspect a failing disk, identify partitions, list recoverable files, and check for bad sectors. A full recovery from a damaged 1TB drive could take much longer, especially if the drive is failing. If you do not trust this person, do not give him unsupervised access. Use a reputable recovery company, ask how they protect customer data, and get the terms in writing.
That is what worries me: I cannot really know whether he looked at or kept anything. I may try to recover it myself or find a company with a clear privacy policy instead.

There is no guaranteed way to prove what someone viewed after the fact, so the best protection is choosing a reputable provider and not handing over the drive to someone who makes you uncomfortable.
