smartctl on a Linux box seems to work just fine. The exact same
model drive
also works just fine in an x4540. So I think the assertion that the
drive
returns random data is demonstrably false.
Your statement that it is "just fine" is false:
---
SMART Selective Self-Test Log Data Structure Revision Number (0)
should be
1
SMART Selective self-test log data structure revision number 0
Warning: ATA Specification requires selective self-test log data
structure
revision number = 1

Like I said, there are ways we could tighten up the FMA code to better
handle bad data before going off the rails - most likely smartctl
gives up when it sees this invalid record, while we (via SATL) keep
going. But any way you slice it, the drive is returning invalid data.
