So you will need a SCSI controler. Two years ago I use to have a CLTD controler and now have a overdrive from (Pacific P..). You will have problem with both when lowformating. The solution is to: with CLTD: use genformat (the only one program that will work). with the overdrive do your own overdrive.drive file with the 4520a spec. Some people got the info from me, so {you could post a message for the file in case you have or plaing to get the overdrive... I get 300k read with the overdrive and 4520a, really easy to beat!. The all setup is for around 270$ (both controler, 8k cache for the 4520a and the overdrive is DMA). Have fun.. Stephan.
