I removed the back up drive from my iMac with out reading directions; just unplugged it! Now I replaced the line into the USB and it is not working and not shoiwng up on the computer. What do I...

Before you unplug an external hard drive, you need to unmount it first. If you don't, you can cause all kinds of problems.The term "unmount" basically means to prepare a drive to be unplugged from the Mac. In addition to external hard drives, "thumb drives" a/k/a "jump drives" as well as some cameras need to be unmounted before they are unplugged.When you unmount a drive, Mac OS X checks to see if you have any open files that are stored on that drive. If you do, the drive cannot be unmounted. This is a safety feature because if drive is removed with open files on it, the application that is using those files can become confused and you can lose or corrupt your data.
If you unplug a hard drive that has not been unmounted, Mac OS X will pop up a box with a red Stop icon and a message that you shouldn't have done that. Nice info, but a little late at that point.
I'm not saying that you will lose data every time you unplug a mounted drive, but the danger is there. I recently worked with someone who had his iPhoto Library on an external drive and he never unmounted the drive before unplugging it. It wasn't a problem for a long time but one time he opened iPhoto and all of the photos were missing.
Unmounting a drive is easy. There is an Eject icon to the right of the drive name in the DEVICES section of a Finder window. Just click that icon.
If you have multiple partitions to unmount, you can hold down the Option key when you click the Eject icon to unmount them all at once.
I thought about it and did some looking and I couldn't find anywhere in Mac OS X that states the need to unmount before unplugging, other than the big Stop icon you get after the fact. I don't think it is something you are likely to think of on your own, either. But now you know.

Will erasing my LaCie ext HD impact any files on my Mac Book?

It will only effect thoes stores on the external harddrive. You will have to check the contents of the LaCie drive and see if it has any files you typically access from your Mac Book. Other then that no it will not effect files stored on your Mac Books drive.

There is some thing wrong with file system on your hard disk drive.
Just unplugg it and wait for 1 min, Plugin again.

1) Go to Application -> Utility -> Disk Utility

2) You can see all the drives connected to the machine.

3) Select the drive from left side which acts as external and click on Repair disk button.
