#fdisk /dev/sdh

The number of cylinders for this disk is set to 38913.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help):

このディスクのシリンダ数は 38913 に設定されています。
間違いではないのですが、1024 を超えているため、以下の場合に問題を生じうる事を確認しましょう:
1) ブート時に実行するソフトウェア (例. バージョンが古い LILO)
2) 別の OS のブートやパーティション作成ソフト
   (例. DOS FDISK, OS/2 FDISK)
