Yeah but it takes ages to recognise the card and boot. HDD/CD access is much faster using FastATA but the Powerflyer has caused me some hassle too. I removed it from my A4000 last night as I kept getting checksum errors and didn't know whether it was the Powerflyer or the drive which was at fault. I've never used SCSI before but I am awaiting the arrival of an A3000 that I will transplant my A4000 cards to and I want to give using SCSI a try instead. I am sick of my A4000 playing up!
