I have the same problem …
Although here is some info.
it worked fine for 4 days. Then i installed guild wars 2 beta (install is a big word; it means copy 3 files, one being 15Gb) on it.
Since then, i cannot play ANY game that makes some disk access, wether it is on this disk or on another, standard magnetic one. The problem happens even right after installing windows again.
i get maybe 10 seconds of play, then F4 BSOD / auto reset. Kernel dump says it was a write attempt that failed.
I flashed the latest bios for my motherboard and for the SSD, tried disabling ACPI, nothing changes.
BUT if i boot on my other HDD with windows XP on it, and then play guild wars 2 beta from the SSD it works fine (ACPI disabled though so it is not that fine).
got core i3 530
1 120Gb SSD sandisk
1 1Tb HDD
This is not a PSU problem, my voltages are very stable even on high load. The most drop i get is from the 12V line that goes to 11.95V .
Now i bought that SSD to get a working and fast windows 7 64, not to get stuck AGAIN on windows XP, so please sandisk do something.
