Thank you Tomasz and Ronny. I'll have to order some hdd soon and try these out. Car battery idea is nice! I may try that.. =) Do they last longer? Ones that fit the UPS original battery spec didn't last very long... part of the reason why I gave up on them.. =P My wife probably won't like the idea of car battery hanging out though ha!
The OSD1 (one with mostly ok OSDs, except that smart failure) motherboard doesn't have any additional SATA connectors available. Would it be safe to add another OSD host?
Regards,
Hong

Sorry for being brutal … anyway
1. get the battery for UPS ( a car battery will do as well, I’ve moded on ups in the past with truck battery and it was working like a charm :D )
2. get spare drives and put those in because your cluster CAN NOT get out of error due to lack of space
3. Follow advice of Ronny Aasen on hot to recover data from hard drives
4 get cooling to drives or you will loose more !

Power was pretty reliable for a while... and UPS was just beeping every chance it had, disrupting some sleep.. =P So running on surge protector only. I am running this in home environment. So far, HDD failures have been very rare for this environment. =) It just doesn't get loaded as much! I am not sure what to expect, seeing that "unfound" and just a feeling of possibility of maybe getting OSD back made me excited about it. =) Thanks for letting me know what should be the priority. I just lack experience and knowledge in this. =) Please do continue to guide me though this.Thank you for the decode of that smart messages! I do agree that looks like it is on its way out.
