Solve : Hot Swap SATA Broken?

1.	Solve : Hot Swap SATA Broken?
Answer» Hi all, I have several SATA (3gbs) hard drives. Also a tray-less SATA Rack. This is a removable SATA drive rack. The drives are formatted properly. When I try using these drives on a friends PC they work perfectly. We can plug them in .. view/modify contents. We can pull the drive and plug in a new one and all works well. However, for some reason these drives will not work on my own two PCs at home. It's a very strange combination of problems. I am using Windows XP Pro with all updates and SP2. The drives power source is a proper SATA Power Connector directly from the power supply (no adaptors) My friend has the same main board and such. So something is missing /broken in my system. (I guess) I've tried a full re-install of windows. Any ideas why my SATA drives will hot swap properly on several friends PCs but not mine? Addition strange happening: IF I first plug any of my drives into a "working" computer (my friends PC) THEN I have the following scenerio: I CAN plug it into my own computer while running (hot swap) and it works normally. BUT if it is left in the computer and the computer is shut down and restarted, it will not work and locks up the system. So it will only work normally as a true hot swap and only after the computer has been started first. I can bring the 1/2 dozen drives to my friends house and have him just plug each one into his system and from then on they will work. But why ?? And also why do they CRASH my system if they are already plugged in after a system start ?? Very weird problem. Do you have a spare PSU with SATA connectors lying around ? ? Hook it up to the SATA Rack and see if this helps...Quote Do you have a spare PSU with SATA connectors lying around ? ? Hook it up to the SATA Rack and see if this helps... Already tried that.

Hi all,

I have several SATA (3gbs) hard drives. Also a tray-less SATA Rack. This is a removable SATA drive rack.

The drives are formatted properly. When I try using these drives on a friends PC they work perfectly. We can plug them in .. view/modify contents. We can pull the drive and plug in a new one and all works well.

However, for some reason these drives will not work on my own two PCs at home. It's a very strange combination of problems.

I am using Windows XP Pro with all updates and SP2. The drives power source is a proper SATA Power Connector directly from the power supply (no adaptors) My friend has the same main board and such.

So something is missing /broken in my system. (I guess) I've tried a full re-install of windows.

Any ideas why my SATA drives will hot swap properly on several friends PCs but not mine?

Addition strange happening: IF I first plug any of my drives into a "working" computer (my friends PC) THEN I have the following scenerio:

I CAN plug it into my own computer while running (hot swap) and it works normally. BUT if it is left in the computer and the computer is shut down and restarted, it will not work and locks up the system. So it will only work normally as a true hot swap and only after the computer has been started first.
