我正在尝试将 Windows 7 DVD iso 写入 DVD+R、单层、4.7GB 磁盘。源 ISO 文件大小约为 2.3GB。刻录机是 hp DVD RAM UJ897，而介质是 Sony D31 DVD+R。
我尝试使用各种工具（Windows 7 的原生 ISO 刻录机、CDBurner XP）刻录 ISO，但都失败了，而且没有提示原因。
ImgBuner 稍微有帮助一点，并给出了以下错误消息：
这是显示的文本：
W 21:09:31 Failed to Write Sectors 256 - 287 - Reason: Power Calibration Area Error
W 21:09:31 Retrying (1 of 20)...
W 21:09:31 Retry Failed - Reason: Power Calibration Area Error
这是否意味着我的 DVD 刻录机有问题？还是介质有问题？我尝试了 2 个磁盘，都出现了同样的错误。

注意：降低刻录速度也无济于事
答案1
PCA 是 DVD 上的一个区域，刻录机使用它来确定成功写入光盘所需的激光功率。它非常靠近光盘的中心。
除了实际的坏介质外，如果镜头或其移动能力存在物理损坏或干扰问题，光盘刻录机也可能会报告介质错误。
请尝试以下操作：
- 如果磁盘倒置，可能会发生这种情况 - 这是很明显的，但检查一下也不会有什么坏处。
- 使用清洁盘清洁驱动器，或用罐装空气轻轻吹气。
- 确保驱动器已安装任何固件更新。
- 刻录光盘之前，请确保没有在光盘上粘贴标签或书写。
- 如果这是台式机，请确保连接驱动器到主板的 SATA 电缆是安全的。
- 删除所有 CD 或 DVD 刻录软件（例如 Nero）并重试。
- 如果这是操作系统/软件问题，则请尝试从 Linux Live CD 进行刻录。
除此之外，如果您尝试不同品牌的 DVD-R 并得到相同的结果，请更换驱动器。
