Yeah, I ran across similar posts that indicate that the RAM was bad in some ways. Are you sure the right drivers are being loaded? For example, msahci, RAID. It depends on the RAID controller what driver you need, as long as you're using RAID. If the drives aren't in a RAID array you would be better off using the msahci driver. If you have an Intel RAID ROM on your board, you could use the Intel Rapid Storage drivers.
Have you stress tested components (Prime95, memtest, Windows Memory Diagnostic, etc)?
No RAID being used. No Intel RST. So purely Windows 7 x64.
I am running only 1 SSD off my W520. I plugged the 2nd one in to see what SSD Toolbox would report.
I suppose that I should try both SSDs on another computer. I have a workstation with 48GB of ECC RAM and 2 Xeons.
I have run Windows Memory Diagnostic (Extended tests) for a while without problems.
Will report with what I find to try to isolate the problem.
I just wish the SSD Toolbox provided more detail. I am not convinced of it's "accuracy".
I wonder how many people that use it have it reporting problems...
Early yesterday, you might have convinced me that toolbox has problems (I started posting here about a problem I have that I thought might be related to that toolbox, but no). But there's another guy/gal posting a similar issue (data mismatch) and it turns out the problem was a setting in BIOS related to memory. In that case, the voltage to RAM had to be increased, and that solved the problem. Not saying your is identical.
I believe I can say this: if your system otherwise runs fine, some hardware component(s) is(are) not playing nice(ly). So, how does your system run?
Tracking this down is gunna be a nightmare. Keep us posted.
Hello Platypus, on this case what I can tell you is that the error that you are describing could be related with many different causes, but we have noticed is that the data mismatch detected error is related with R.A.M memory and SATA controller miscommunication errors on most of the cases.
I suggest you to update your BIOS of your system to the latest version use the latest SATA drivers, perform a memory test to confirm that the R.A.M is working properly and you can try also to remove one dim of memory or use the minimum memory for your system and test the Solid State Drive again.
