最近、「ShowDrive」という新しい外付けドライブがありました。しかし、「TV」フォルダには何も表示されません。フォルダにアクセスしようとしたときlsだけInput/output error。
pi@raspberrypi:~ $ ls -l /media/pi/ShowDrive/

-rwxrwxrwx 1 pi pi 549227 Apr 22 2022 'Install Western Digital Software for Mac.dmg'
-rwxrwxrwx 1 pi pi 671824 Jul 9 2021 'Install Western Digital Software for Windows.exe'
drwxrwxrwx 1 pi pi 0 Nov 19 09:12 'System Volume Information'
drwxrwxrwx 1 pi pi 24576 Nov 21 14:06 TV
たとえば、他のフォルダはうまくSystem Volume Information開いているようで、Windowsコンピュータで開くのに問題がないようです。
