Hi there willy chi,

Is the drive recognized by BIOS?
Is your system working properly now? In case it is, you need to get the data off the drive and test it with a brand specific(or a third party one) testing tool, that will provide a SMART report.
In case your system won't boot and you have some data stored on the drive, you will need to attach it either internally(SATA&power cables) or externally via SATA to USB adapter. After that, you can try to access the drive right away or you can use some data recovery tool: http/www.tomshardware.co.uk/forum/id-1644496/lost-data-recovery.html

Let us know how this goes,
