The drive cache_type is set to "write back" if it plugged in. The drive is working using if I set the cache type to "temporary write through". So, I think this is the exact same problem discussed here. At the moment I tested the workaround using v3.18.2 (gentoo-sources). Without the workaround the problem also exists using the Kernel v4.0.4 (used gentoo-sources, but I think that should not be related to the problem at all). Is there anything I / we can do, to solve this problem at all in the kernel space (e.g. if SYNCHRONIZE CACHE command is not working, fallback to write through)? -- You are receiving this mail because: You are watching the assignee of the bug.
