I need your help mga, bro.

hindi na mabasa yung external hd ko, it's an 80-gb seagate, 3.5 ", that i bought back in 2004.
recently, hindi na sya mabasa kahit saang pc or laptop pa sya i-connect. . .i thought it could be the housing so i brought it to cdr king and connected to a new housing pero hindi pa rin nabasa ng pc nila dun

wala it has not been subjected to any shock and there is not any sound coming out of it indicating tha it is damaged

questions:
me pag-asa pa ba 'to?
is there any pc shop (preferably in the qc area) where i can take it that can retrieve the data stored in it?

maraming salamat
