Having a bit of an issue.
First off. System is stock. I haven't OC'd anything yet. AHCI mode. SSD boot drive in SATA0, data drive(s)s in SATA1, DVD drive SATA2.
i5 2500k (stock until this is figured out)
2x2Gb G.Skill 1600
Antec Basiq 430W
No extra GPU, stock Intel is good enough for right now.
Some random USB2 HDD enclosure
Seagate Go Flex "desk" 2TB USB2 (put the destroyed WD20EARS in the USB enclosure and recovered the files to the Seagate .. both worked flawlessly in 6 days' time )
No other peripherals at this time have been installed.
My problem is that I keep losing my "data" drive. No matter what drive I happen to put in the system.
Initially I thought my WD20EARS had just died (again) but it has been flawless in a USB enclosure for the last 140-something hours recovering the 1.4TB of data this caused me to lose. In that time another drive I installed in its place actually has come and gone several times without reboot. It has shown up without any input from me and left without my input. It isn't showing up anymore as the last time it did Windows said it needed to be formatted.
I have run 2 other drives in that time and they ALL do it. They're fine in USB enclosures though.
They always reappear at reboot. They drop out after no certain amount of time. no rhyme or reason. After a few times of it dropping out, it is no longer recognized and Windows says it needs to be formatted. (this is why I have spent so much time recovering the files from the first drive... )
I have tried with and without Intel RST drivers
. I updated the BIOS on my board. I've tried all the other SATA ports.
I have not tried not running AHCI mode cuz that'd be stupid.. I NEVER lose my boot drive. I have not had any BSODs.
System is set to "Always On" power mode, hard drive turn off to "never", screen always on, etc.. S5 is enabled in the BIOS but the computer hasn't slept in the last 6 days due to recovering the first drive since then.
There seem to be a lot of Event logs that seem to point to the drives going bad, but I know the drives are good. They all work flawlessly in USB enclosures FWIW.
any help? The mobo/cpu are new, swapped from a h67 board and i3-2100 to a z68 board and i5 2500k.
I attempted to open a ticket with Gigabyte, but it's been 3 days and I haven't heard back from them yet. Kinda p/o'd about that.
