I got the MB star diagnosis SD Connect C4 Dell D630 HDD (hard driver), when i installed the HDD into the Dell D630 laptop. The laptop asked me to select safe mode and required starting windows normally.

Error cause:
You did not normally shut down the computer when you insert the hard drive.

Solution:
Wait for 30 seconds. Start windows normally. Re-start the laptop,it will back to normal.

BTW,check your HDD format is ata or achi. We recommend set to achi mode in Win7 or Win8 operating system.
