Corruption without deferred writes

I've now experienced data corruption on 2 different 2008R2 Terminal Servers after installing Primocache. Write cache on, deferred writes were not turned on. Running v2.2.0. No reboots or crashes. Just progressive corruption.

Same here on Windows 10, seems to happen only when L2 cache is enabled.

@dwright1542, can you give me the detailed cache settings? Thanks!

This wasn't L2 cache enabled. 10G cache size, 4k blocks.

Another 2008R2 now with a corrupt filesystem with write cache on, no L2, no deferred writes. Third time is a charm, disabling all write caching. No reboots, no power issues, no OS crashes on any of these systems.

I'm sorry for the corruption. This issue seems quite weird. We have asked our testers do more long-time tests on 2008R2.

Also try with fully updated Windows 10 and IntelRST.
