VERIFY命令请求用于UFI设备校验设备上的数据。
VERIFY Command格式
- DPO:为0
- ByteChk：为0。USB-FDU仅检查介质上的CRC数据，无数据比较
- RelAdr：为0
- Logical Block Address:该字段指定验证操作开始的逻辑块LBA。
- Verification Length:验证长度字段指定要验证的连续逻辑数据块的数量。验证长度为零表示不会验证任何逻辑块。这种情况不会被视为错误，也不会验证任何数据。任何其他值表示将要验证的逻辑块的数量。
如果验证命令成功完成，UFI设备应将检测数据设置为NO SENSE.,否则，装置应将传感数据设置为下面列出的适当值。
