I recently set up a couple of hard drives on my RPi and it was all well for a week or so, till a couple of days ago one of the drives started clicking. I realized this might mean the drive is failing, and I started getting I/O errors anyway. I tried rebooting but somehow RPi would hang on boot trying to mount the drive, but I could boot fine when the entry was commented out in fstab (RPi would also become unresponsive and hang after running 'sudo mount -a').
I figured that the signs point to a dead drive, but when I connected the HDD to my computer, the drive ran smoothly, with no rhythmic clicking, and I rsynced ~300 GB to my computer with no problems. I should note, though, that trying to verify the disk on my computer, I get the error "inode 899, i_blocks is 2894400, should be 262144", and while I guess that was caused by the clicking noise, it did not seem to affect the file transfer or file integrity, or bring the clicking back.
So now I'm thinking that the drive is fine, but maybe it was not powered adequately by the USB hub? However, it seemed to have been running smoothly for a week and then suddenly started clicking and failing without having changed anything in the meantime.
I'm using this USB hub
, and this HDD external enclosure
. I'm aware that USB 3.0 devices may use more power, but the enclosure seems to be USB 2.0 compatible, and I don't see why the hub should have any problems powering it.
Sorry for the rambling post — I guess my main question is:
is there any way I could check how trustworthy the USB hub is to use with my new HDD, and also rule this incident as simply a drive failure that is not related with the hub's power output?
Thanks for any feedback!
