I got that too on my Mac Studio. And I don't know if it's a bug or something real. Seems the code that generate this error is something like this: https://github.com/mirror/smartmontools/blob/0df69a95136fd4299c6887b03d13e3f09bda7ff8/os_darwin.cpp#L578 https://github.com/mirror/smartmontools/blob/0df69a95136fd42... It simply calls `GetLogPage()` on the `IONVMeSMARTInterface`. Apple documentation is as usual devoid of content. https://developer.apple.com/documentation/iokit/ionvmesmartinterface/3521169-getlogpage?changes=__8_1&language=objc https://developer.apple.com/documentation/iokit/ionvmesmarti... But I found this `745` value `0x2e9` might be #define kIOReturnDeviceError iokit_common_err(0x2e9) // the device is not working properly! https://opensource.apple.com/source/xnu/xnu-344/iokit/IOKit/IOReturn.h.auto.html https://opensource.apple.com/source/xnu/xnu-344/iokit/IOKit/... Device not working properly?! Or is it just a shit driver?
