Is that the only time? If it's ONLY a sleep issue, then include that in your search for help! You didn't mention if/that it was specifically related to sleep.
If it's a windoze-based HD, try to wipe it on a windows machine before you return it. All companies have bad batches of products. I don't think it's worth messing with too much - it's your data, after all.
contact and send the other one back to seagate. get another drive asap and copy everything to it. while the prob was caused by seagate, i suspect that 10.5.7 makes it more problematic (as mentioned in this thread). Don't reformat! I meant try it on a mac w/ an older MAC OS! like 10.3.9, 10.4.x or 10.5.6.ġ0.5.7 and my last Seagate 'windoze-oriented' purchase didn't play well together.
