Linux: hdparmがPI4で正しく機能せず、hddスピンダウン時間を制御できません

バグを説明する
hdparm -I /dev/sdaが機能しておらず、 hdparm -y /dev/sdaような同様のハードディスクコマンドも失敗します。

root<strong i="10">@raspberrypi</strong>:/home/pi# hdparm -I /dev/sda

/dev/sda:

再現するには
hdparm -I / dev / sda
hdparm -y / dev / sda
hdparm -C / dev / sda

期待される動作
ハードディスクのスピンダウン時間の設定をサポートします。
pi3では、すべてが正常に機能します

同じUSBハードディスクを使用してpi3で同じコマンドを実行すると、すべて正常に動作します。

追加のコンテキスト

1. 同じusbハードディスク、pi3ではhdparmは正常に動作しますが、pi4では動作しません。
2. usbハードディスクをpi4のusb2.0ポートに接続します。機能しません。
