Currently Being ModeratedJan 20, 2011 12:33 PM (in response to Cerebro)Id like to piggyback on this. I have very similar setup and condition, 15" Macbook Pro 2.4Ghz Core2 Duo, coupled to a LaCie Quadra D2 320 Gb drive connected with a FW800 cable. I'm running OS 10.6.6.
I have tried erasing, verifying, and repartitioning, the drive (now it only has one drive partition). I have verified the drives on the Mac and LaCie, rebuilt the permissions, zapped the PRAM, and even did a reinstall of the OS (not clean). The setup has worked for a year or so until recently. I can get the drive to operate normally for the first backup only (58Gb)which I suspect is not complete. Then subsequent backups get as far as "calculating changes" with a spinning beachball. This can last for at least a day but on the most recent 2nd time through backup, it had a time out after about a minute. The dialog box that popped up said it could not create a backup folder. In the recent past it has caused the finder to hang and the only way out was to use the power button on the MacBook.17" iMac, Mac OS X (10.4.3)
Currently Being ModeratedJan 20, 2011 8:17 PM (in response to scot)Solution- Apparently the LaCie Drive was damaged. It would not mount a different laptop at all. I have gone back to the wireless Time Capsule and all is well with the world. I think this fell victim to being unplugged without being ejected from the computer first. I caught the wife doing this a couple of times. Points out though the value of Apples no worries wireless backup system being combined with a laptop.17" iMac, Mac OS X (10.4.3)
Currently Being ModeratedJan 21, 2011 7:00 AM (in response to Cerebro)It seems my last fix was the solution to the problem. Deselecting the "Put Hard Disk(s) To Sleep When Possible" option in the Energy Saver preferences did it for me. My computer and Time Machine have both been up and running for over three days without a single hiccup.MacBook Pro 15.4 inch 2.53 GHz Intel Core i5, Mac OS X (10.6.5)
Currently Being ModeratedJan 21, 2011 7:18 AM (in response to Cerebro)First of all, why am I not allowed to edit my own postings? (the forum isn't letting me for some reason).
Anywho, I would still like to solicit people's opinion on the "no sleep" option. From what I gather, the cyclic spin-down/spin-up puts greater wear and tear on the drive. Since the drive needs to be written to every hour (per TM's automated scheduling), that's a lot of constant cycling. My feeling is that deselecting this option is better all around.MacBook Pro 15.4 inch 2.53 GHz Intel Core i5, Mac OS X (10.6.5)
Currently Being ModeratedFeb 11, 2011 11:46 AM (in response to Cerebro)I am getting the same thing, but mine seem to be a little different. About 60-70% of my backups work fine, but a couple of times a day I will go to my computer and see time machine "Calculating Changes" with no end. @Cerebro-I have my "no sleep" option unchecked and also have the update to my Seagate external so it never goes to sleep installed, so I don't think it is the sleeping causing the problem. This is very annoying. What I have been doing is killing time machine with "sudo killall backupd" , then unplugging the harddrive, then running "sudo service com.apple.metadata.mds stop" and finally "sudo service com.apple.metadata.mds start". This is the only solution I have found that doesn't involve doing a hard restart.iMac, Mac OS X (10.6.6), 8 gigs of ram

I too am getting a never ending write to my USB external drive for TM. And this is only a recent matter as of this January. I have been using this drive - also a 1 TB Fantom Drive - for more than a year for manual TM backups. I am using the drive for additional storage and the TM backup files. I preferred to do my own back up timing manually, so every couple days I tell it to back up when I go to lunch. Been working GREAT! Loved it... till now. Now I can't get a completed back up. TM continues to run. I am not a tech user so can't tell you anything about the logs you have posted. Are you reporting this from the Console Messages?
My set up is 27" iMac late 2009, Core 2 Duo, USB direct connected Fantom 1TB ext drive. OSX 10.6.8 3.06 GHz, with 4 G RAM. Also running a second monitor. Nothing all that special. Will try the "Put to Sleep" setting off, mine was on... i have tried the PRAM, Disk Utility to reset permissions, have run cocktail to do all scripts, clear caches and scripts... made sure I had all firmware and OS updated... all software updated... Still same problems... However, been looking at other posts dating back to 2009 and found this interesting link perhaps Spotlight is our newest - revisited problem... http://www.thexlab.com/faqs/stopspotlightindex.html#Anchor-Preventing-49575.
I just forced the indexing to stop on my ext. volume and the the silence is great! I am still reading... but is it possible in the Sys Pref to have spotlight not index a folder such as the backup file/folder that TM creates, yet let it index my additional storage files? Or do I have to choose a complete volume? Each time I try to tell spotlight to not index Backups.backupdb I get a "Privacy List Error - Item cannot be added or removed because of an unknown error."
Lastly, I don't see a solution according to the link... it seems that no matter what, if the appropriate index file is backed up to the ext volume, no matter what indexing will start.
Any comments or thoughts? Does this help anyone here?

Toss me into this group. But I'll add its going to a up to date Time Capsule.
This problem leaves me with the feeling that TC/TM is unreliable and should NOT be used for true back ups.
I used to like it, but I guess glitz trumps function once again.

There's a 15-minute time limit.

There's little hard evidence. Modern drives are built to run 24/7 if necessary. Most have a built-in sleep or spin-down mode after 10, 15, or 20 minutes of inactivity, so they're designed to do that, too.

You have other data in the same partition as your backups? That's not a good idea. See Time Machine - Frequently Asked Question #3.
You can exclude the drive from Spotlight indexing (System Prefs > Spotlight > Privacy), but you cannot keep Time Machine from indexing them. See the Note: in section 2 here: http://docs.info.apple.com/article.html?path=Mac/10.6/en/8991.html
EDIT: See #D1 in Time Machine - Troubleshooting for more.

As an update. I had trashed the TimeCapsule and started fresh. Was great until the TC got full. Now stuck on calc changes again. I'm DONE with TM & TC for back ups. It just pure junk and too unreliable. back ups are the one thing that needs to be perfect (or as close to as possible). CCC and Super Duper for me. (or heck, just dd will work)
