Should I try to connect hard drive after unsafe removal?

Ok, thank you!

So… The (My Book Studio Edition) HD shows up in System Profiler but nowhere else. Also won’t turn off with button and light has been steady (on standby?). Is this the right reconnection procedure?..

…[Power down Mac, unplug Mac power cord (from back), unplug HD power   from the back, unplug FW data cord from Mac then… Reconnect power cords, turn on Mac and plug data cord back into Mac?] …If it does show up I guess the next step will be to decide if  files are corrupt.

P.S.  If I need help with the next step; do I add to this or start new subject/post?  I am new to forums. Thanks again:)
