I'm not sure if it's a faulty enclosure, or what, but it does the darndest thing. The whole system and all services will halt during prolonged disk access with the enclosure. Just noticed it now while I was creating a disk image of a laptop onto the server (a 2009 mac mini). The whole server hanged and services halted (DNS, AFP, LDAP, etc.) I attempted to force quit, but everything was a beachball and unresponsive -- everything except Disk Utility. The progress bar for the image creation was continuing. Instead of hard-shutting down (holding the power button down) the server, I decided to unplug the target disk booted laptop instead. After about 15 seconds, I get the "Improper device removal" notice (along with all my clicking that was queued up during the beachballing), and all the services kick back up again (DNS, AFP, LDAP, etc.).
Is there a specific log I can look at to get more detail on this abnormal firewire behavior?
Thanks,
