Hi,
[My configuration info is below] My drive, which I purchased from Amazon in December, came with SD23 and very soon after installing I noticed that it would occasionally spin down (and therefore "pause" the system) while I was web browsing in Safari or Firefox. I noticed it most often when browsing Facebook but that may just be because I do that the most. The spin down during web browsing always happened when a page was loading, not any other time. I also found that sometimes when I closed the lid of my laptop to put the computer to sleep, it would go to sleep and within 5-15 seconds I would hear the computer wake up and the HD spin up. If left alone, it would go back to sleep on it's own between 15-30 seconds. I had one experience of the battery dying overnight, possibly due to it self-waking and not returning to sleep. I have since installed SD24 and have had at least one instance of each of the symptoms above, but far less regularly - a step in the right direction!!
Additional notes:
- I'm almost always plugged into AC power, but I think I've noticed symptoms on both AC and battery.
- I currently have Time Machine running (via WiFi), but noticed symptoms prior to turning it on.
- I use a cooling pad that plugs into a USB port, but noticed symptoms with & without it and never have it in when I put it to sleep. Other than that I have no devices attached to the computer.
- The only background utility I have running is Little Snitch network monitor (not the filter) which I had prior to installing my Momentus XT and before the symptoms appeared.
- I have never heard any "beeps" or other unusual sounds from this drive (though I am familiar with what that sounds like).
- Next time a symptom occurs, I will immediately look in the Console for any relevant information and post it for you.
CONFIGURATION:
- Momentus XT 500GB (SD23 -> SD24)
- 15" MacBook Pro 2.4Ghz (Mid/Late 2007) Model A1226
- 8GB RAM
- Mac OS X 10.6.5 (upgraded to 10.6.6 after SD24 update)
- Advanced/Power user of Macs for many years
