Im running my DRU500A in a firewire enclosure I got from compgeek.com (ME-320F). At least once or twice a night my computer total freezes up. If i turn off the firewire enclosure everything comes back to life. I turn it on again and its fine...until it freezes again usually a few hours later. I've burned only 2 DVDs so far and it didnt freeze when it was burning. Just seems to freeze when doing simple tasks like surfing the web. Anyone know what could be cause it? Im running an AMD 2000+, Shuttle AK31A(VIA KT266A chipset), 512mb PC2700, WinXP pro, adaptec firewire card.
