clean install LION won't recognize my external hard drive

i updated to lion - my system was slow. i bought a hard drive (samsung G3 station) today and backed everything up. then did a clean install of lion - now lion wont recognize my external hard drive anymore.

i really need those files.

my harddrive turns on when i plug it in - Lion won't recognize it tho.

please help

thank you

is your external a mac formatted hd? (hfs)
or a windows one? (ntfs)

if its ntfs u need an app to make ntfs work

if its hfs, do you see the hd in "disk utility" app? press repair if u see it. that wont delete your files btw.

good luck

I upgraded to Lion - it slowed my system. saved EVERYTHING on my external HDD. (it recognized my hard drive then)
then did a clean instal of Lion - everything works fine EXCEPT IT WONT RECOGNIZE MY EXTERNAL HARD DRIVE ANYMORE, even though it did previously, when it was just an UPGRADE.

any help?
