Hi, One of my HDs, LaCie d2 case 180GB (pre triple interface, has FW400 and USB 1.1, about 3 years old i think) has recently been performing as such... Drive boots fine, no unusual noises. Copy to okay. Copy from, often displays an Error code -36 and then disconnects. Drive history: Not to long ago the drive disconnected itself a few times, which I did think was odd but didn't have time to investigate it. Most of the content on the drive is backed regularly and the stuff that isn't I am working on transferring. I have found that if a file won't transfer that I can shut it down for a while, letting it cool down and then copy it okay upon rebooting it. Apple's disk utility says that it is okay. Any ideas as to what might be causing the error and if a utility like DiskWarrior would fix it? Should I jump ship and get a new one? I really think that this is punishment for having purchased a DS Lite on the tax free day instead of getting a new HD as was planned... the new HD was not a replacement drive but to be an addition. Thanks.
