Let me get a bit more detailed for you...regrettably. lol
yeah, they are storage drives.
the funny thing is I had connected them earlier when the bios settings were IDE so I know there were working and not corrupted, and they remained disconnected during the entire build up until the problem occured. The pc they were connected to that I was in the process of building had 4 vertex 60gb ssd's that were about to be configured for raid0 using the mobos ich10r chipset. I had done several win7 installs(nothing to do with the storage drives at this point) to test stripe sizes with the ssd's in raid. after each install you need to sanitary erase the ssd's to clear them(like a format) which requires that they be in IDE mode. So I was constantly entering the bios and switching between IDE and RAID. All of this was to test ssd raid performance on the Intel chipset prior to installing an LSI megaRaid storage card I had been planning on using, and wanting to compare performance gains. I did stripe size test installs on the LSI card too, again between each win7 install I would have to Sanitary Erase the ssd's and switch to IDE mode in the bios to do so. So during the final switch I accidentally selected AHCI and didn't realize it. (I was about to remove the ssd's from the intel sata ports and switch to the lsi card ports, so in theory I didn't even need to change the storage settings from IDE to anything.. But it had been many hours with little sleep)
I didnt notice my mistake right away because at this point I was using the raid card and not the onboard sata ports on the motherboard (which is an Asus P6X58D premium by the way). Once I finally connected the drives(there are four 1TB drives, but at first I only connected 2 of the 4, sure glad now I didn't do all four!
![:??: :??:]()
) I noticed that they were asking for a format like they were new. Upon freaking out about that I checked the bios and saw the AHCI setting...smacked myself, and switched back to IDE mode and tried again.. Same "would you like to format" screen. So I disconnected those 2 drives, and tried the other two via IDE mode and no problem.
ALL 4 1TB drives had previously been in the old system and used via IDE mode. And like I said, I had previously checked all four of them on the new system and all four were fine. (before configuring any raid stuff or even the ssd's for that matter) And again only 2 of the four have the corruption, and only the two that were connected via AHCI. SO I am 99.9% positive that somehow the AHCI bios setting caused the corruption. And whether IDE or AHCI the intel storage manager handles both. But obviously its a different driver, which I recall windows 7 automatically installing upon booting up with these two drives plugged up via ahci(AFTER all the testing was done and the 4x60 ssd raid was setup on the LSI card. and they were NOT connected at ANY point in between). So I'm not really trying to figure out how it happened, but more so, how to reverse it.
