LaCie Quadra runs at times when not in use

I am running Snowleopard with a Lacie quadra as a backup/clone external drive. I have noticed that every so often the drive just starts up and runs for about 10 seconds or so (either I hear it or I see the blue light flashing). I am not running a backup at this time or doing anything with the drive. I don't see any setting set to autobackup on the mac. I have tried reindexing it and still the same issue.
Any help is greatly appreciated

Do you turn the drive off using the switch at the back? If you leave it on and mounted, it will run occasionally when it detects something (I don't know what, but mine does the same thing).

How to have time capsule sleep when not in use

Is there any way to have my time capsule sleep (stop spinning ) when not in use? it runs constantly and gets warm. I need to find out how to make it idle and wake up when my Mac calls for a backup. Does anyone know if this is possible and if so, how to do it? I have the time capsule connected to a router off of a cable modem. Thanks to all

Is there any way to have my time capsule sleep (stop spinning ) when not in use?
Does the disk spin up and down continually? Or is it just spinning non-stop?
What model is the TC? Please give the A1xxx model from the rubber base mat.. and size of the hard disk.
Did you update to the latest firmware? When did the problem start, ie did it correspond with firmware update?
Have you played with it.. replaced the drive etc? If this is stock standard it should spin down almost immediately disk access finishes.

Should I turn off my Mac Pro when not in use or leave it running?

I have been told I should never turn off my computer by some people, and others say that I should always turn it off when not in use! I use my Mac Pro primarily for music recording/editing in my home studio or word processing. Now that I have an iPad I use that for web browsing, email, FBing, etc. and I find myself on my Mac Pro a lot less. I get the basis behind both trains of thought; those who leave it on feel always stopping and starting up puts unnecessary wear on the moving disks, and those who shut down think if the parts are always moving they are bound to wear out faster. I am not as concerned with conserving power as I am with keeping my machine safe! If you have any information on this topic I would love to hear it. Thanks!

Providing you have a robust firewal and are not worried as a result about being hacked then leave it turned on and allow it to sleep. Make sure you allow the screen to sleep as well a that is the item that is more prone to damage by being left on all the time.
I never turn my machine off, never have with any of my Macs ever since my first one back in 1979-ish and have never suffered any adverse affects. Today, the power drain is so small when allowed to sleep that I doubt they would offend even the ardent 'turn off everything and pull out the plug to save the planet' person.
If you have an iPad or iPod synced with the Mac for email and iCal and address Book etc. then if you leave it on it should be up to date as soon as you return home, mine is anyway. With iCloud coming out very soon that may come into play even more so with all its advance pushing etc. Just a thought.
One advantage in leaving the machine on (sleep) is that you can access it from anywhere in the world should the need arise with the appropriate settings, which you can't if you turn it off.
Leave it on.

Macbook air runs hot and makes noise like processor running hard when connected to display - even when not actively using air book

macbook air runs hot and makes noise like processor running hard when connected to display - even when not actively using air book

You could use the free tool iStat Pro to see what changes when you connect your MBA to the display. Without doing anything the CPU pane should show a high percentage for "Idle". If the idle value is too low, launch the Activity Monitor and sort by CPU usage. There is a pane showing the different temperatures of your computer. Watch them for a few minutes after connecting the display.

Should I shut down my computer when not in use

should I shut down my computer when not in use, overnight for instance?

Hello! Leaving it on 24/7/365 is perfectly acceptable. You may save some electricity but personally I think you'll pay for it with a more troublesome system. I do however set the monitors to go to sleep. I like the no startup lag time of running 24/7/365. That said, if I lived in an area prone to electrical outages or if my location was prone to lightening strikes I'd probably shut it down and unplugged. Of course with it being unplugged the pram battery may run down. These old G4's have been running 24/7/365 for years now. I do try to restart every few weeks just for good measure! In the end it's your preference. The hardware works best when a constant temperature is maintained. Tom

Imac shuts down when not in use

I purchased my 21.5" imac July 9, 2011 with Snow Leopard. No problems for 1 month. Then about August 12th or so, my imac started to mysteriously "shut down" when not in use. I'll be working on it, then get up to go pour myself a cup of coffee or something...then I come back to my computer that has now shut off. It is NOT asleep...it is OFF. So I turn it back on and it is fine. This has happened a few times now within a week. Anyone else have this problem?
By the way, I am now running Lyon, as of August 18th. When the imac shut down, I was usually viewing photos or on the web.
thanks!

First thing I would try is to reset the SMC, it can help with power related problems. Shut down the Mac and unplug everything including the power. Press and hold down the power button for 10 seconds. Plug in the computer but be careful not to press the power button as you are plugging it in. Wait a few seconds and turn it on. Hopefully it won't happen again. There is always Apple Support. Don't let the problem persist until your free phone tech support has expired (3 months). I would also recommend using the iMac with an UPS, and at the very least, a high quality surge protector.
If you have MS Word or a similar word processor you could try enabling the autosave feature and set it to 1 minute intervals. Keep a document open and if you come back to the computer and it has shut down, you can look at the last time the document was updated and know what time the comptuer turned itself off. It could be useful in diagnosing the problem.

Photoshop 5.1 bombs when not in use and often disables keyboard

I'm using Mac OS X 10.7.2 on an Intel Core 2 Duo IMac. A few months ago I downloaded PhotoShop 5.1 after having used every previous issue of PhotoShop without a problem.
1. Often when I have Photoshop open on my desktop but not actively using it, it will freeze and I'll have to force quit and restart. When I installed the latest version of InDesign and Illustrator they would also freeze when not in use, however removing and resinstalling them seemed to fix the problem for them, but not for Photoshop.
2.I will be working along on a project when suddenly all of the alphanumerical keys on my keypad won't work. I ultimately have to restart the Mac to get them to work again in any program. This never happens with any other program and I have tried othe keypads, even one just out of the box, and it's always the same.
I have removed and reinstalled Photoshop twice, but still the same issues.
I have called the Adobe helpline and tried all of their fixes, but it still happens. They resolved that it must be my Mac. But Mac says because it is related to a specific software it is not their problem.
Any ideas?

Thanks for taking the time to respond.
It might be Suitcase 3, because I keep having trouble with it and issues with the FM Core.
I'm also getting this prompt which I don't know how to resolve: "Photoshop has encountered a problem with the display driver, and has temporarily disabled GPU enhancements. Check the video card manufacturer's website for the latest software. GPU enhancements can be enabled in the Performance panel of Preferences. (I couldn't find it in the preferences and not sure who the video card manufacturer is.)
Here is the other software that usually is or may be running at the same time as Photoshop: InDesign 7.5, Illustrator 15.1.0, ITunes 10.5.3, Mail 5.1, Preview 5.5.1, Suitcase Fusion 3 14.2.0, Firefox 9.0.1, Microsoft Word 14.1.4 and Excel 14.1.4; less often: PowerPoint 14.1.4, ICal 5.0.1 and Address Book 6.1
When I first had problems with this install as I mentioned I upgraded my operating software and donwloaded MacKeeper to clean things up. It hasn't helped.

Apps wanting to access my location when not in use (and not giving the option to turn it off)

For most apps, I can choose to share my location 1) not at all; 2) when the app is in use (my favourite); 3) always (even when not in use).
Why do some apps not offer the second option?
For instance, I want to use an app that locates the nearest automatic external defibrillator (if someone has a cardiac arrest) but I can only use the app when I allow the app to access my location all the time. Given the fact that I will use this app perhaps only once every 15 years, I see no point in giving them my location for the next 15 years! That's just a waste of battery power and also a breach of my privacy.
Second example: Apple's own weather app. I check the weather maybe once every month. I do not want the app to locate me all the time. But I can only choose between option 1) and 3) above.
Is there a technical reason apps work like this? Or are they just sneakily trying to get as much information about me as possible?
Thanks for your thoughts.
PS: I am using iphone 6, iOS8.3

everything rudegar said is right on. Still, 10% overnight is more than you would expect - so something is still running. try-
double click the home button, and see what apps are listed as recent. one or more of them might be still churning away. it is a good idea to close those out fully every night. Any of those apps with notifications or location services may be checking in every now and then and using your power.
you mentioned airplane mode is 'off'. this may be a terminolgy thing - but having airplane mode 'off', means that the radios are on. WiFi, and 3 G if you have it. turning airplane mode "on" turns off the radios.
with everything off on mine - (except I leave the wifi on) - i use 2 or 3% overnight.
But if you really want it off - do what rudegar says.

IPhone 3g shuts down randomly when not in use.

I'm running iOS 4.0 on my iPhone 3G, which I bought used. It shuts down by itself randomly when not in use a few times a day. It never shuts down when in use or when plugged in. I've seen other posts on something similar but no solution. Please help

I have a similar problem, it shuts down, when it's locked, it shut's down, when im using a aplication, it shut's down when im not using it, it's shuts down when it's even plugged in, some say it can be the battery but i dont think so.

Is it possible to let the TS-HD go sleep when not in use

is it possible to let the Time Capsule HD go idle when not in use for saving energy?

If the Time Capsule is functioning normally, the hard drive will spin up automatically when a Time Machine backup begins and spin down after the backup is completed.
My Time Capsule normally runs for a minute or two for the backup each hour....otherwise the drive is not active.

WHEN TO USE SYS_REFCURSOR AND WHEN NOT TO USE REFCURSOR

SYS_REFCURSOR is a Weakly Defined Cursor
DECLARE emp_refcur SYS_REFCURSOR;
when this is so simple
why this
DECLARE TYPE emp_cur_type IS REF CURSOR RETURN emp%ROWTYPE; my_rec emp_cur_type; ?
Can anyone explain in what situations we should prefer among these ..when both can give same result set .

> WHEN TO USE SYS_REFCURSOR AND WHEN NOT TO USE REFCURSOR
When the requirements define that one is better suited than the other.
There are no hard and fast rules about when to use a specific tool. There are however basic concepts of what the purpose of the tool is, and what typical problems the tool can address.
Ref cursors in PL/SQL.. usually not the best of ideas. Ref cursors are designed for client-server processing.
1) The client makes a request for data/information.
2) PL applies the back-end server logic and construct a SQL statement for the client.
3) PL passes the SQL to the SQL engine where it is parsed and a SQL cursor created.
4) PL passes a reference handle to SQL cursor back to the client
5) The client can now fetch the rows output from the cursor.
Advantages.
- The client does not need to know SQL, db structures, business logic, etc
- The PL code can be improved, modified, new business logic added, without even touching a single byte of client code
So what are the advantages where the "client" in the above is another PL/SQL program? None really.
A "real" client (an external one like Java, C#, Delphi, etc) can receive the ref cursor handle and dynamically at run-time determine the projection (output) of the cursor.
PL code cannot (unless using the latest 11g features). In PL code, a ref cursor is actually implemented as a DBMS_SQL cursor. A DBMS_SQL cursor is to PL code what ref cursor is to Java/C#/etc.
So whether you define a strongly typed or weakly typed ref cursor in PL/SQL code... typical response is "so what?" as ref cursors are not really intended for PL code. Not that there are exceptions - they do come in handy at times.. but as exceptions to the rule.
So my response is "so what?" - it is more important to *correctly" chose what type of client cursor data type you want to use to interact with the back-end SQL cursor. Once that decision has been made (based on technical sound logic), then one can look at (minor) issues such as weak vs. strong ref cursors.

Overheating when not in use

For the last few days my MacBook has started to become extremely hot when not in use. While I am using the MacBook it is not hot, this issue only arrises when I am not using it. The energy savings are 3 minutes for computer sleep and screen sleep. I can hear the internal fan is still working.
Any ideas what has suddenly changed would be welcome. Thank you.

The condition has continued. After selecting sleep and putting the computer to sleep, it will start up again at will without any interaction. This occurs when disconnected from the internet.
There have been no changes in configuration or installation of new software.
I thought this awakening of the computer could be a character of a virus program or Unix maintenance programs. But this didn't occur before and no matter now many times I put the computer to sleep it continually awakes. All I can assume is some component in the system has changed by itself.
It is not really an issue as such, but the problem is that when the computer awakes by itself the fan doesn't run (usually the fan is running when the computer is warm - so the fan is still functioning) so the computer becomes like a hotplate, which could lead to damage of the motherboard. I usually find the computer really hot after being out or in the morning.
Any ideas as to what is causing these self starts would be helpful.

Is Chromium Spying When Not in Use?

I just learned of a tool called "nethog", installed it and watched to see what programs were generating traffic on my computer. One of them was chromium, which is funny because I wasn't using Chromium.
I've known for some time thanks to "top" that chromium runs when I'm not using it. I thought that it was annoying, and that it embedded itself into some autostart file, and was just taking up memory so that it would launch faster for when I actually opened it. However, I never suspected that it was generating network traffic when not in use.
I've since uninstalled Chromium, but I ran whois on one of the IPs that it was connecting to. It was Edgecast, a "Content delivery" service owned by Disney.
Is anyone else seeing this?

So to be clear, other people are experiencing this, and are OK with the idea that Chromium is running, and communicating with websites when the browser is closed (and hasn't been opened in weeks across multiple boots)?
Sure it is open source, but it is also big, complex, and created by a company that is very interested in harvesting your data. I tend to think of Google as a benevolent giant, and I have a certain amount of faith in the open source process, but you could probably hide a small city in chromium's source code, or an vulnerability the size of the San Andreas fault.
Heh, maybe I'm paranoid, or maybe I am after all the only one that experienced this after all. But to be honest, programs running without my explicit permission, phoning home in ways that I could not easily control or understand were a large part of the reason that I left windows so many years ago.
Actually it does have your permission and it *can* be useful. You can just deactivate it with unticking "run in background". I like it as I'm sometimes too lazy to open up another mail program and thus just fire up GMail and get notified of it – even when not running in foreground.
So yeah, there's a not-spying reason for it but we can't really know whether this is the only reason ^^.

Leave iPhone in charger when not in use?

Can you overcharge an iPhone? Shall I keep it in the charger when not in use?

You can not over charge the battery by leaving it plug in for long times.
