small drives are old and usually unreliable. most of the stuff you'll get will be living its final moments most probably. If I were you, I'ld get a brand new 9.1 - 18 gb drive and use the first 4 gbs. These drives are slowly phasing out and I guess stores are trying to get rid of their stock at the moment, so they're available new. You may need to get a SCA-50 pin, 68-50 pin converter, which can also be found easily.
