Board: DZ77BH-55k
AAG39008-400
Bios version BHZ7710H.86A.0057
Windows 7 Pro (64bits)
SSD drives: Intel 520 240Gb and Samsung 840Pro 512GB
I have connected both drives to (BB) blue SATA 6.0 Gb/s connector through the PCH.
Both show up in Bios.
Both have Windows 7 installed.
- Booting in bios with Samsung Pro SSD:
Both drives perform well, both available in Windows.
- Booting in bios with Intel 520 SSD
Intel drive performs well, Samsung SSD does not show up in Windows, needs to be initialized.
On initializing there is an error:
Virtual Disk manager:
Data error: Cyclic Redundancy check
After failing, Windows Disk management shows a 900GB drive but it is not accessible, I cannot open it from here or from Computer>Hard drives.
This Samsung drive performs with no problems, Windows was installed on this SSD connected alone to this board.
Provisional solution: I have attached Samsung Pro drive to a SATA 6.0 Gb/s connector through Marvel 88SE9172 controller (gray). (I have connected the Intel 520 instead with the same outcome)
Problem: Performance degrades noticeably (as tested with AS SSD Benchmark and Samsung Magician)
Questions: I would like to be able to use both SSDs from the blue connectors, do not know why the Samsung drive (When c:/ is Intel 520) needs to initialize, why it fails (when it's not the booting drive), and how to solve it.
Regarding the Bios, I am still using the first one released (0057), I have not updated it after many problems reported, contrary to many other Intel boards I had in the past, where I updated them on a regular basis.
Now with version 0100, would I gain something updating my bios?, is it safe?, or better stay as it is?
