我不知道如何正确描述错误，但我会尝试......
好吧，我的外部硬盘中有一个包含音乐的文件夹，没有任何可见的模式，几分钟后，Totem 抱怨它找不到文件并停止播放......我可以看到外部硬盘被自动弹出并重新打开。文件在那里，如果我从列表中删除它并放回原处，它会播放而不会出错。
但几分钟后，另一个文件又出现了同样的情况。
我注意到，只有在 Totem 正在播放时才会发生这种情况。也就是说，当 Totem 未播放时，HD 不会像我上面描述的那样弹出。
这不是什么大问题……但对于注意力缺陷多动症患者来说，这很烦人！而且我失去了我仅有的一点注意力。=/
我会很高兴接受你提供的任何帮助。
编辑：当从内部驱动器播放某些内容时，Totem 没有这种行为。

根据最新编辑的新答案
Buffer I/O error on device sdc1, logical block 210570671
此消息可能表明驱动器即将出现故障。
首先：如果您还没有备份，请先备份！
然后检查重新分配的扇区数（smartmontools）。如果您看到重新分配的扇区，我认为您应该尽快更换驱动器：
smartctl -a /dev/sdc
还要检查您的文件系统（不知道您在该磁盘上使用哪个 FS）...
旧答案
请检查以下命令的输出：
for d in /sys/bus/usb/devices/[0-9]* ; do if [[ -e $d/product ]] ; then echo -e "`basename $d`\t`cat $d/power/control`\t`cat $d/speed`\t`cat $d/product`" ; fi ; done
第二列将显示是否允许（自动）或禁用（开启）自动暂停...
