I have had a Lacie USB (500Gb) external usb drive for a while. Besides being a very loud drive it's been working up until recently. Its rendered useless when connected to my intel iMac with Leopard because it locks up OS X so bad that I have to physically power it down and restart it. I mostly use Linux but I do admit to loving my wifes mac and use it very often at home. I really thought that it was a corrupted filesystem or hardware issue with the drive but when I connect it to my Suse (11.0) system it mounts it. It appears to be read only but I'm thinking that the ownership and permissions are causing that and will not change that because I would like to resolve the issue so I can move it back to the Mac.
