I would agree ... but thought worth checking the connections ....although how you would bend anything is unlikely as the disk just slides in without any play as far as I rememberWell, it's not working.
Although the fact that the reports are from EXT4-fs indicates that an ext4 file-system was put on it. So it was accepting writes then. For a filed controller I'd expect to see it fail all of the time. Intermittent failures sound more like a disk issue (happens when that part of the disk gets used).
