I can't dispute yours or Greg's success. At the time this was an extra 2.5" IDE drive in a cheapo USB to IDE case bought off ebay (IIRC) years ago. It was separately powered and I had it configured so the entire root file system was on the HD with only /boot on the SD as I recall. It would routinely lock up at least every seven days and sometimes sooner. The only cure was to pull power and reboot. This is an application that writes to an sqlite database every few seconds and uploads weather data to sites such as Weather Underground and CWOP (Citizen Weather Observer Program). The Pi handled the load, but I suspect the IO was just a bit much for the share interrupt design. > The only time i have seen datacorruption with another Pi was on the SD-card > not on the HDD. (I have 5 Pi's working 24/7) I have two Pi Bs, one is doing duty as an amateur radio packet reporting system digipeater and the other is running Libreelec and Kodi as a frontend for my MythTV DVR. Both running off SD cards with no issues. - Nate -- "The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true."
