我每晚都会在 510 个不同的文件（总是相同的文件）上收到以下警告消息：
警告：无法读取“[在此处插入文件名]”的部分内容。备份数据已损坏或不完整。此文件无法正确恢复。
我正在运行 SBS 2003，并且备份正在写入外部 USB 硬盘。
一些相关信息：
- 这个问题已在 3 个不同的外部硬盘上重现。这不太可能是存储介质的问题。
- 该问题已出现至少 2 个月。
- 在驱动器 vssadmin 列表编写器（在命令提示符下）上运行 chkdsk 后问题仍然存在，没有列出任何编写器上的错误。
- 备份硬盘上创建了 .bkf 文件。除了有警告的文件外，我可以成功恢复所有文件。有警告的文件可以恢复，但已损坏，即无法打开（原始文件可以打开）。
- 过去备份已成功完成。
- 我最近更换了硬盘，因为旧的 500GB 硬盘已接近容量上限（因此备份失败）。我使用的新硬盘是 4TB。但这个问题在旧硬盘和新硬盘上都出现了。
- 服务器还存在另一个问题，即其操作系统分区已达到容量上限，这导致了一系列问题。通过将 Exchange 数据库移至数据分区，解决了该问题。操作系统分区上的备份始终成功。产生错误的是数据分区。我怀疑该问题与服务器操作系统分区上的存储空间不足有关，因为该问题大约在同一时间（不到两个月前）开始出现。

这是本周早些时候执行的 chkdsk 的日志。

这是昨晚备份的日志。我省略了所有错误消息，只留下一条通用消息。它们都一样，但一共有 510 条。
