Storage disk reparable?

I started using getchannels on a PC several years ago, then moved to a raspberry pi about a month ago. Once it was announced that the pi wold no longer be supported, I moved to a dedicated windows 11 machine. All worked fairly well for a couple weeks.

I ended up with an error message that my files could not be found, even though the list of shows was still available. I moved the drive to a desktop computer for further troubleshooting & found that the power supply in the disk enclosure had failed, putting 24V to the drive. I figured it was toast, but after checking I was very surprised that it still seemed to work except for the partition where the shows are which shows to be unformatted. A scan of the drive showed a normal drive, testing for sectors & tracks!

Does anyone have any idea how to find/repair the problem that is keeping me from getting to the shows or a package that will allow me to at least copy the shows off? I just plan on getting it up only long enough to copy the files to a new drive.

Thanks in advance.

Try running a: Chkdsk /f on the drive first.
