If your external hard drive is not showing up when connected to your computer, this can happen for a variety of reasons. Sometimes, it’s a matter of minor corruption, which can be resolved with a quick scan. Even Chkdsk, which is built into Windows, can occasionally resolve those issues. In other cases, the drive might need to be formatted before it can be recognized again. This results in data loss – though if a quick format is used, and the right precautions are taken (such as disconnecting the drive immediately after the format is complete), there is usually a high chance of recovering that data. In more severe cases, a disk might not be recognized due to physical damage. If the disk’s controller gets damaged, this is usually not fixable without expert assistance. And if the disk plates themselves are damaged, that disk can be written off. Recovery is sometimes possible in specialized facilities, but chances are low and the cost is typically prohibitively high for ordinary consumers.

If the device is recognized, this should trigger a fresh installation of drivers.
