Hi,
I have one USB removable HDD. After plugging it to my usb ports, I can
mount FS and read/write,
but if I unmount it and unplug it , the system gives so many errors. Even
though I do not mount and umount FS,
only plug and then unplug USB HDD, the errors occur as well. The following
is my syslog after unplug and plug
this USB HDD:
