    Bit of a simple question, does it matter what position the jumpers are on a 3.5" hard drive? Having a bit off hassle from a Icy box external drive.

    many thanks

    I believe that for most cases you're going to want the jumper 'disabled' or in the cable select position. If that doesn't work, it is certainly 'Master'. You wouldn't want it set to 'slave' in this application.

    Got any more details about the drive? Do you at least have a jumper pinout printed on the drive? If not, you should be able to find it online based on the brand/model.

    Thanks Trepex

    Well its working now, bit strange why.

    It was a Icy box usb / firewire enclosure with a hitachi 500gb hd.

    Looking in disk utility the device would be present but no hd. the device name was garbled and reporting a 2 tb drive? trying to erase or partition would respond in disk utility crash or a inout/output error.

    Anyway put the hd in a old pc to format it in ntfs (cant remeber), put it back in enclosure and its all working fine, just formatted it into apple

    To be honest not overly impressed with icy box, cables a bit on the short side
