I got the 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.
You did not normally shut down the computer when you insert the hard drive.
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.
