Re: Code error 27

code 27 means the test timed out, it may be caused by multiple reasons: host side, drive side, even connection, if you have concern about the SSD health, please feel free to contact our support and provide full dashboard report

Re: Code error 27

[ Edited ]



got the same error code 27 with


SanDisk SSD Dashboard,

S.M.A.R.T Diagnostic Extended Test,

boot drive SanDisk SSD Plus Solid State Drive, SDSSDA240G, Firmware Z22000RL

Windows 10 Home 64bit (Version 1703, Build 15063.483)

PC HP h9-1250eg


The test never completed on any try.


My workaround: Restart Windows 10 in "safe mode with network" and let run the extended test, dashboard started as Administrator. This is always successful with my machine and the longish test ends without an error ocde.
