Hello. I would like to report a bug in the new version of Intel RST 11.5. Once installed on Windose 8 RP computer hangs and causes BSOD with error iaStorA.sys. My SSD is in the mode AHCI. Windose 8 RTM comes out the other day, and it would be nice if this problem was solved as soon as possible. My motherboard ASUS P7P55D-E. Thx. (Sorry for my English.)
It turns out that the problem is not in the driver Intel RST but in AIDA64 2.50 Final. Since I updated Windose 7 to Windose 8 RP in my startup was this same AIDA64 and loading some drivers are not compatible with the new Intel RST and a system crash BSOD. I just installed the Intel RST on the freshly Windose 8 RP and no crashes. The problem is solved. For those who use AIDA64 download the latest beta version.
Good question about the SATA controller being recognized as SCSI in Windows, that has happened with some beta drivers as well.
I would not use IRST 18.104.22.1687, it was just removed from the download page of the Intel 7-series chipset boards (excepting X79, which uses RSTe) and does not perform as well as 11.2 drivers. I noticed this around 8PM CST on 8/2/12. IMO, IRST 11.2 or earlier versions are fine.
There might be a new driver that is being rolled out since it seems 11.5 may be history. I've seen claims that SCSI drivers do not pass the TRIM command to SSDs. You can install earlier IRST drivers over 11.5, just skip the warning about installing an older driver.
