Hard Drive works externally but not internally

i found this thread Hard Drive works internally, but not externally. which is opposite to my problem and its been a year since the last post. So i make a new thread.

As you can see in the title. My Hd drives works externally but not internally.

I have 4 HD`s

1.) ST31000528AS
2.) WD500AAKX
3.) WD6400AAKS
4.) ST500DM002 ( this is my local hd)

the rest is my other hd drive but not connected. Now i want to add atleast 1 or 2 hd to my computer. So I start adding the first one which is the #1 drive the ST31000528AS. I plug the cables to the hd then turn on my computer. But its always freezes at the bios screen then it will turn off automatically.

I tried all the other hd drives from 1-3 drives i listed above. They got the same results. So i searched about the problem and i found this thread Bios screen freezes on startup . I also used the disk clean command. To format my hd. But the problem still persists.

That problem occured only when i connect it internally but when i connect it externally its working fine. What do you think is the problem?

I tried replacing the sata cables and connecting it to different sata port. But got the same results :3

The Hard Drive J is the ST31000528AS. Connected externally and it`s working fine.

Hello hinaruu!

Just to make sure if I have understood correctly.

You have 4 internal hard drive, one of them (ST500DM002) is your OS drive, which is 500GB SATA III. You have only the OS drive connected to the motherboard and when you try to connect any of the other three HDDs to any of the ports using multiple cables, your BIOS freezes and PC turns off? But you can without a problem connect the drives externally?

Are you receiving any messages, or beeping sounds from the motherboard? I would first advise you to back up anything important from the OS drive to another one.

Then disconnect your OS drive and plug it to another port and start the PC. Does it work? Then power off again, and plug one of the other three drives on the first SATA port where the OS drive previously was. Try powering up again. This should give you sense if the ports have a problem or the drives.

Then reset your BIOS. Carefully pull the CMOS battery out for about 15-20 seconds then put it back on place. Be very very careful! Then press the power button of the PC for 15 seconds to discharge any remaining power stored in the capacitors. By discharging the power, the CMOS memory will reset, therefor should reset the BIOS. Then connect the drives again, firmly, to data and power. Test again.

I see your motherboard has 4 SATA ports, which are SATA II. Some of the drives are SATA III, but the ports are backwards compatible, so this shouldn't be the issue. But I believe that your motherboard ports may be damaged.

Do post back with results to troubleshoot further! :)
