Arch 在写入时杀死 USB 记忆棒

每次我将东西复制到 U 盘时，写入的数据都是 0 字节。
步骤如下：

$ dmesg | tail   
 ... as sdb1 ...   
$ mount /dev/sdb1 /mnt   
$ mount | grep /dev/sdb1   
/dev/sdb1 on /mnt type vfat rw,relatime,fmask=0022,dmask=0022,codepage=437, iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro)  
$ cp /path/to/file /mnt   
(1-2 seconds pause)

此后，提示符再次出现，表明命令已完成。

但：

$ df -h   
(All my mounts EXCEPT /dev/sdb1)

$ umount /dev/sdb1   
Special device /dev/sdb1 not found   
(Unplugging the drive and reconnecting it)   
$ dmesg | tail   
... as sdc1 ...   
$ mount /dev/sdc1 /mnt   
$ ls -al /mnt/file   
rwxrwxrwx user group 0 file

为什么它只复制索引，而不复制文件？30 分钟后也没有任何变化。
顺便提一下，每个非 root 用户在尝试写入任何内容时都会收到“权限被拒绝”的提示。可能相关。

将文件复制到设备后发生这种情况。我试过几个 U 盘。

添加 2：以用户身份执行 rsync -av 日志

sending incremental file list
file
rsync: mkstemp "/mnt/.file.09oDMm" failed: Permission denied (13)

sent 303,348,282 bytes  received 119 bytes  86,670,971.71 bytes/sec
total size is 303,274,124  speedup is 1.00
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1189) [sender=3.1.3]

与root操作相同：

sending incremental file list
file
rsync: mkstemp "/mnt/.file.tVJ2Th" failed: Input/output error (5)

sent 303,348,282 bytes  received 119 bytes  202,232,267.33 bytes/sec
total size is 303,274,124  speedup is 1.00
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1189) [sender=3.1.3]

添加 3：在驱动器处于清洁状态后对其进行 rsync 操作，然后对其进行 fsck

$ fsck /dev/sdb1                   
fsck from util-linux 2.33
fsck.fat 4.1 (2017-01-24)
/file
  Contains a free cluster (6032). Assuming EOF.
/file
  File size is 303274124 bytes, cluster chain length is 0 bytes.
  Truncating file to 0 bytes.
Reclaimed 9256 unused clusters (303300608 bytes).
Free cluster summary wrong (457661 vs. really 466917)
1) Correct
2) Don't correct
? 1
Perform changes ? (y/n) y
/dev/sdb1: 2066 files, 6534/473451 clusters

这肯定是我的 pendrive 出了问题，因为另一个 pendrive（NTFS）工作正常……

答案1

最后再来结束这个问题：我的 USB 驱动器确实坏了。两次。再也不会购买 SiliconMotion 控制器了。
