auction question

[orange]

lets say I've bought HDD on an auction site (similar to ebay) and it cost 5eur+2eur postage.
if it was broken and I return it, should I pay for both postages (the seller returning only 5eur)?

well it was advertised as 'working'. I specifically told the seller to pack it properly which he ignored and put it in plain cardboard.  then he claimed I can return but its my cost. (I assumed only one postage and returned the item)
he also wants me to give him positive feedback before getting any money back.
what would you do?

hm, I didn't expect an interesting discussion.
well here are more details:
the drive is SCSI (unsurprisingly) and its 18Gb.
it was a local auction, the seller is in the same country and postage was about 2,5eur (as for most things here)
interesting note, the auction did state that it was 'reopened' because the last buyer decided to quit. maybe that should have been a hint.
he has some negative feedback already.
BTW, IIRC I had never left negative or even neutral feedback here or on ebay.
didn't plan on leaving positive now, it was either negative or forget-about-it

I forgot to say, the drive was probably broken in first place.
the (68pin) connector was damaged and HDD behaved like completely dead. the scsi interface couldn't even 'see it'. (it would spin up and then heads start banging)
if only the mechanics was broken it should have been at least 'visible', right? and I doubt the PCB died because of shipping.
