LinuxでUSBスティックの不良セクタをチェックしつつフォーマットする

More than 5 years have passed since last update.

USBスティックは頻繁に読み書きするとよく壊れるので、不良セクタのチェックを入れてフォーマットすると良い。

/dev/sdxは適切なデバイスに置き換えてね
sudo mkfs.vfat -I -c -v /dev/sdx

man mkfs.vfatより

-c  Check the device for bad blocks before creating the filesystem.

ということで、不良セクタをチェックしてくれる。直す、とは書いていないので、チェックして表示するだけかもしれない。
これを外せば普通にフォーマットする。

-Iはデバイスにパーティションテーブル作らないオプション、-vは処理状況を表示するオプション。
