The 7200.11 debacle! It was unbelievable that it happened- as far as I remember, Seagate was the leader in reliability before then, I had created five or six RAIDs with Seagate drives with 100% reliability.
But when they released the 7200.11 versions....ALL 7200.11 models would spin down after idle for X minutes and then start clicking...the data was still intact, but for the drive to work again you had to pull the power.
I unfortunately built an eight drive RAID5 with these drives before the issue was know, which made it very difficult for me to diagnose the issue. (All drives seemed perfectly fine when powered and working for the first 5-10 minutes or whenever they were in use, but as soon as a single drive of the RAID idled, the RAID5 acted like a drive was bad).
I still have a box with eight 1TB Seagate 7200.11 drives that I never updated. I have never bought another Seagate drive for RAID since, always WD or Hitachi.
Sghodas- I think you are missing the point. By your math and 'rational' it seems there shouldn't be an issue. This spill was not some homogeneous mixture you can easily calculate in PPM. This chemical has travelled wholly through the water plant into the water supply- solubility doesn't matter. Two to seven days have elapsed between intake from river, through filtration/ozone treatment, to holding water tower, then into public use. How many PPM do you think are in the green ice cubes someone found in their freezer? And at what PPM does ingestion cause long-term health effects?
It's not insoluble, it is up to 3% soluble. "Most likely not enough to harm anyone." For some reason the state has declared it a federal disaster?
check out this green ice- look, it's not soluble! Fine to drink! http://i.imgur.com/pzBsLRP.jpg
The "68" recording had me wondering if this was a real person, which was terrifying. Some people have been saying this could be a soundboard operated by a person, which does seem plausible. I probably would have said Cirrus, Socrates, particle, decibel, hurricane, dolphin, tulip.
