我有一台 Synology RT2600ac 路由器OWC 水星精英专业版（USB、eSATA、FW800）外部硬盘。该驱动器被检测为/dev/sdr任何 ol' USB 闪存驱动器被检测为/dev/sda或sdb。为什么sdr又不呢sda？这是 RAID 设备约定吗？
我说 RAID 是因为外部机箱使用智微JMS5662芯片它支持两个磁盘的硬件 RAID0 和 RAID1，即使该机箱仅支持一个驱动器。过度设计的罕见例子？
这是更大的探索的一部分，旨在弄清楚为什么该驱动器每次重新连接或重新启动路由器时都会不断获得新的 GUID，并因此忽略创建的任何文件夹共享。
需要明确的是，文件夹共享仍然存在于，/usr/syno/etc/share_rights.map但不是稳定的 GUID，驱动器获取值RANDOM__13-digit-hex-GUIDin /usr/syno/etc/usbno_guid.map，并且 share_rights.map 中的文件夹共享映射到先前颁发的RANDOM__13-digit-hex-GUID分区号。
不幸的是，lsusb这不是一个可用的命令。以下是输出dmesg -T | grep usb

大家对此有什么猜测吗？ （我已联系 Synology 支持并正在等待第 2 级支持。）
万一出现：
Synology RT2600ac 正在运行 BusyBox v1.16.1
它已更新为最新软件 - SRM 1.3.1-9346 Update 9
