I am rsyncing 500 MB from one usb drive to the other. If any of the drives should fail, the whole system hangs. For example, if there is a power glitch in one of the drives, the whole system hangs. As you may know, some of the external enclusores and/or power cables can get in the way and even the slightest movement can disturb the drive. What I don't understand is why does it have to hang the system?! Has anyone else experienced this? I mean I can understand that you may get corrupted data etc. but how is it possible for a failed write operation to hang the complete system!? Maybe this issue is only related to USB drives? Both drives are USB 2 and have UFS. Thanks beforehand for any feedback or ideas.
