I have an external 5.25 USB to IDE Case (which I used for a DVD drive earlier). It`s something like this. Now I was interested in getting a 320GB Seagate IDE HDD and use it in that case. But the dealer told me that external cases dont work well with drives bigger than 200 GB. I checked the net but i didnt find any size limitation for the HDD to be used in such cases. I dont want to be stuck with a drive I cant use. Can someone confirm this please.Thanx.
