Something is seriously wrong in lala land. Tablo 4 Tuner (Not Quad), up until last month, had been running pretty decently. Then it killed the 1TB drive. That was connected via powered USB 3 hub. Contacte T-Support, they were looking into it, may have been drive failing. Was also sent another power supply. Used power supply, threw on a 80GB portable, also powered through USB 3 powered hub. Guess what? That drive failed same way as first. Speaking of first, was able to recover it by (eventually) re-initializing as MBR, formatted as EXT4, put on Tablo, and away it went. Then that drive died, again. Same issue, reinitialized as MBR, formatted partition as EXT4, put it through 5 days of non-stop testing on my ubuntu box, no problems. Connected it to Tablo, dies within the hour. Found another drive, a 320GB SATA3 HP portable (WD drive). This time, connected it to Tablo raw, and let it format it. Wanna guess what happens? Yup! That drive dies, within 2 hours. No hub used this time, drive current is 380mA runing, 500mA startup.Within capabilities of USB port.
Had a hell of a time trying to get the damn thing to reset. Finally successful. Will be following up with T-Support come Monday.
On the upside, I had moved over to an APC Backups 1000va UPS. After DC supply testing went very well, decided that I really didn’t feel like building anything. Found the UPS at a garage sale, needed to new batteries (24v). I wasn’t going to buy them either, but instead wired together 2 Grp31 deep cycle trolling batteries and placed them on the floor under the desk. Given the storms that have been blowing Houston around, the system has worked out fantastic. 3 laptops, 2 montiors, Ink Slinger, Laser Shooter, several external hard drives, WRT3200ACM router, Linksys 3016 cable modem, and a TV did not even make a dent in normal usage from the battery/UPS. I guess from sheer capacity, the conversion losses just don’t make any difference.
