What would happen if my mac os hard drive failed

so i have 2 hard drives
1 for windows bootcamp and 1 for mac
as it is now, i boot to the windows boot manager then choose my copy of windows.
what would happen if my mac os hard drive failed right now?
would the computer still boot and be unaffected unless i tried to boot to mac?

failure is usually not dead. It can be a bad sector, but usually it is a directory issue or just the partition table (but which require either quick or long format)
if you have a workstation, you should clone both operating systems; you should not put them on the same hard drive. And you just use the clone you made for each (Paragon Clone OS for Windows $19; Carbon Copy is sharefare for OS X)
both of those allow booting off the new hard drive while you figure what you want to do or what happened.
If you only have two hard drives use the other drive bays.
Basically NOTHING happens if you pull one or the other.

What would be easier to add more hard drive space?

Hi, I have an iMac G4, 1.07 GHz powerpc, 1.25 GB ram and a 40GB hard drive. I would like to have more space and saw 120-300 GB hard drives on Other World Computing and wonder if it something I could do myself (I installed the Ram upgrade myself) or would an external hard drive be better?
I want this for iTunes mostly so I can get an iPod touch for shows and podcasts. Thanks in advance for any help.

Geek Squad is definitely an option? But unless you just absolutely do not know you way around a screw driver and no longer have any dexterity then I would suggest doing it your self. It's really not as hard as you think, it just looks overwhelming.
Just make sure that you get the correct guide from iFixit, get all the tools that they specify, take your time and don't pry... You'll be fine.
If you are pressed for time and do not feel at all comfortable using tools then yeah take it someone to have them do it for you.
If you decide to perform this on your own just report here during the process and we'll be here to assist you with what we can.

Transfer songs from iphone to new mac (my hard-drive failed and has been replaced), some songs i have bought on itunes and others were old copies, any ideas?

hi
i have recently had my mac hard-drive replaced and consequently have lost all my old stuff - had to download a new itunes for example. i synced everything onto my iphone before it broke luckily. some songs i purchased on itunes, others i downloaded ages ago from CDs. how do i transfer these onto my itunes library again so i can sync?

iTunes can transfer your purchases or you can download them again. Downloading past purchases from the App Store, iBookstore, and iTunes Store: http://support.apple.com/kb/HT2519
For songs ripped from CDs, you need to use a 3rd-party utility. Here are two that will help you.

Brand new hard drive failed - is it me?!

Hello (Kate HS's other half here)
I recently had to replace the HD on our iMac (the original one failed more or less on it's second birthday)
I fitted a 250gb Hitachi drive about a month ago, restored data from backups and everything seemed great, until tonight...
I was watching TV via Eye TV when the computer froze - and when i forced shut down and restarted I was greeted by a blinking question mark. Booted from Disk First Aid and it couldn't see the HD. Hardware test shows " 2STF/1/4 " error.
Could it be that something other than HD could be causing this - or some other fault is destroying hard drives? (first time i had warning noises and regular crashes for a few days, this time there was nothing - instant death)
Could I have done something wrong when fitting it?
Or what are the odds of having 2 hard drives fail in the space of a month..?
Hope you can help.

To Apple Discussions!
Since your HD is only a month old it should still be under warranty. I would contact the manufacturer and/or get a new one.
In case it's not the HD, see your computer comes under the following program since you have an 20" G5 iMac. Hopefully, it's a Rev B:

Satellite C660 - My Hard Drive failis to boot up

My Laptop is a saterlite c660-c66od Running windows Server 2008 32BIT with 3gb ram and it started going slow and then the whole system crashed i rebooted it and then it would not load up saying my hard driver failed to boot i then booted it up in linux Ubuntu on a live disk and was able to acsess my Files then i rebooted thinking the hard drive would boot and it still failed. i have tried booting it up again in linux but it wont work
I have Lodes of confidential Documents that are not stored anywhere else and i really need to gain acsess to it is there a way i can recover or fix my HDD or am i going to lose so much data my company is going to crash amd burn

Hi
In most cases the data is lost if the HDD is faulty and you did not create any backups.
But I found also nice offer from Toshiba here:
http://eu.computers.toshiba-europe.com/innovation/services/home
Here choose Data Recovery.
You can purchase different Data Recovery Service for Hard Disk Drives. Such services is good for the future. Now you could ask Toshiba hotline for other date recovery services but of course you will have to pay for such data recovery.

I just backed up my mac to an external hard drive using Time Machine. What would happen if I turn Time Machine off and then plug the external hard drive back into my computer?

I just backed up my mac to an external hard drive using Time Machine. What would happen if I turn Time Machine off and then plug the external hard drive back into my computer?
What I am ultimately wanting to do is make more room on my computer by backing up all of my files onto the external hard drive and then deleting them off of my computer. However, neededing to be able to retrieve them from the external hard drive later down the road.
From what I have read and am trying to understand, is that I probably shouldn't have used time machine. I need to use the external hard drive like a basic flash drive where I can put things on and get things off without having it automatically update through time machine everytime I connect it to my computer.
Not tech savvy at all and barely understand basics. I need very simple and easy to understand explanations.

BIG BIG MISTAKE ..... youre making a linchpin deathtrap for your data trying to shove everything on a single fragile HD.
Dont suffer the tragedy other people make, buy another or 2 more HD, theyre cheap as dust.
The number of people who have experienced terror by having a single external HD backup is enormous. One failure that WILL HAPPEN, and kaput,......all gone!
Dont do it, its all about redundancy, redundancy, redundancy.
follow here:
Methodology to protect your data. Backups vs. Archives. Long-term data protection
Deleting them off your computer is fine....having only ONE copy is extremely BAD.
The Tragedy that will be, the tragedy that never should be
Always presume correctly that your data is priceless and takes a very long time to create and often is irreplaceable. Always presume accurately that hard drives are extremely cheap, and you have no excuse not to have multiple redundant copies of your data copied on hard drives and squirreled away several places, lockboxes, safes, fireboxes, offsite and otherwise.
Hard drives aren't prone to failure…hard drives are guaranteed to fail (the very same is true of SSD). Hard drives dont die when aged, hard drives die at any age, and peak in death when young and slowly increase in risk as they age.
Never practice at any time for any reason the false premise and unreal sense of security in thinking your data is safe on any single external hard drive. This is never the case and has proven to be the single most common horrible tragedy of data loss that exists.
Many 100s of millions of hours of lost work and data are lost each year due to this single common false security. This is an unnatural disaster that can avoid by making all data redundant and then redundant again. If you let a $60 additional redundant hard drive and 3 hours of copying stand between you and years of work, then you've made a fundamental mistake countless 1000s of people each year have come to regret.

What would happen if I were to delete all the files on my Mac Mini?

I was just wondering...Since i've owned my mac mini for a while now, overtime i've managed to have kept A LOT of files on my mac...
I don't want to delete individual files as that would take forever, but what would happen if I would delete every file and restart my mac? Just out of curiosity

What would happen if I were to delete the primary email address linked to my Apple ID?

I wish to completely de-activate my @hotmail email address in order to be left with just my @icloud email address becuase I would find life more managable that way.
I found out that I cannot change my primary @hotmail email address linked to my Apple ID with an @icloud email address as it is an active, separate Apple ID (in itself with a separate purchase / download history etc)...
Also I am aware that separate Apple ID's cannot be merged together...
My question is: "What would happen if I were to delete the primary email address linked to my Apple ID?"
Would I be able to keep and use my purchases, provided they are backed up on my Mac and authorised?
Would I be able to update those transferred purchases even though the email address linked to the apple ID in which the app was bought no longer exists?

You can change the primary e-mail address associated with your Apple ID, so long as it isn't a mac, me or icloud email.
http://support.apple.com/kb/HT5621
Your Apple ID account, regardless of the primary email, can never be 'deleted', just abandoned.
You could always just switch between the two Apple IDs as needed, to access the different purchases.

What would happen if I forgot to click on eject, before disconnecting ipod?

Is it neccessary to click on the eject button before disconnecting my ipod? What would happen if I forgot? Would I lose all my music?

Ejecting is so old school. I just unplug it like I have been doing for years. No problems yet. I figure that the hardware shouldn't be affected even if there is a little data loss and if it is, it's crap and I will take it back.
I think the ejecting legend has become a remnant from old-school mac days that hangs around to keep you from unplugging while syncing. Shouldn't be a problem....at least from what I have experienced on Windows. I am not sure if Macs still require that ejecting stuff on external media...

What's the difference between client combo and server combo? Also, what would happen if I install both?

what's the difference between client combo and server combo? Also, what would happen if I install both?

One is for the base version of the Mac OS, the other is for the Server version. You can only install the one that matches your system.

What would happen if two concurrent threads try and remove ....

Hello,
I have a java test to give back tomorrow and I'm stuck on this question, could you help me please.
Question: What is the difference between java.util.Vectorand java.util.ArrayList?
I read everywhere that: The main difference between Vectors and ArrayLists is that Vectors are synchronized so any method that touches the Vectors content is thread safe, which is not the case for ArrayLists.
This part is ok.
Now the second part of the question is:
What would happen if two concurrent threads try and remove the third object
of such a collection?
I don't know what to answer. I could tell that if the vector or arraylist is smaller than 3 il will return an ArrayOutOfBoundException but what happen if they are longer?
Thank you very much.

I wouldn't say anything about Vector or its methods being thread safe.
Thing is, [Vector javadoc|http://java.sun.com/javase/6/docs/api/java/util/Vector.html|javadoc] does not state anything like that.
Rather opposite, javadoc says Vector hates concurrent modification just like any other non-concurrent collection: +"...The Iterators returned by Vector's iterator and listIterator methods are fail-fast: if the Vector is structurally modified at any time after the Iterator is created, in any way except through the Iterator's own remove or add methods, the Iterator will throw a ConcurrentModificationException... Note that the fail-fast behavior of an iterator cannot be guaranteed as it is, generally speaking, impossible to make any hard guarantees in the presence of unsynchronized concurrent modification..."+
This part is ok.I don't think this part is OK. I would stick with wording given in javadoc: +"Unlike the new collection implementations, Vector is synchronized"+ // synchronized does not necessarily mean thread safe, and Vector is the case proving that

Leopard for G4 867mhz or above. What would happen on G4-400mhz?

what would happen installing Leopard on less than a G4-867mhz?
Would it work but be too slow for apple to be confortable supporting?
Or do those machine lack hardware support?

I'm not really a fan of old OS's, programs, or cobbled machines that I've built. They did the job, but I kept saving my money for better results.
Most of the G4's, expecially the iMac's can not be upgraded with anything but ram. Your done. Some people are trying to get Leopard to run on 400 mhz G4 iMacs with their included video cards and chips on the motherboards. Now if you're talking about a tower like my Dual G4 1.42 Ghz then you're right, I've already added all of the hardware I wanted, including the ram, video, USB2, bluetooth and gigabit ethernet. But I started with a very capable machine that was worth upgrading. The limit here is the speed of the motherboard bus, and the slower G4's should be just put out as a Tiger game machines and save your upgrade money for a new iMac. I've moved the old machine into a back office to run Leopard server, and got the wind tunnel out of my workspace. When the ATI 9800 pro video card bit the dust because of a fan failure, I just put the original card back in and don't need the high end video on a headless server.
The upgrades I did were to keep my production machine up to speed for a couple of extra years, but those years are long past, and my MBP and iMac's run rings around it for less money. Every Mac I ever bought before the Intel Mac's cost $3000 plus upgrades. These new $1100 to $1400 machines blow them away. I played with drop-in CPU's from Newer Technology in the past (they only cost 3 or 4 hundred), and they worked for a short time, but invariably I needed to run special patches from the vendor to be able to even install the later OS's.
I'm not sure what you mean when you say you didn't touch the hardware at all. It seems like you changed everything that wasn't soldered to the motherboard (except the CPU and maybe ethernet). It sounds like you've been able to buy your way up to it's present level, piecemeal. OK. The fact that you got an older machine to run faster than it did has nothing to do with how fast or reliable a machine made in the last 3 or 4 years will run, natively, supported by Apple with all updates and drivers, video improvements, built-in camera's, etc. All of the improvements you made, and much more are already available with much higher performance on the new iMac's. There are so many people who believe that Leopard will speed up their computers just by installing the OS. They should have just stayed with Tiger and got Leopard with their new machine, just like the millions of Vista users who expected speed for nothing.
WinXP will run on an early slow 486 processor. You'll save a lot of money if you do it. What's the point? I don't buy computers based on how little I have to spend to get work done (that's the PC mentality that drives me nuts as I wait for the machine and the hour glass to get back to me). I buy them based on how much work I can get done. When a program's developers decide not to upgrade or patch their program for the new OS or architecture I bid them a fond farewell and move to a company who makes products that perform well with my new machines. These machines and existing programs do not improve with age and developers who want to sit on their laurels and reap income from old work just seem to fade away. Adobe and MS are doing their best to write better code, as are thousands of independent programmers.
It's time for Snow Leopard to re-establish MacOS as a performance OS Leopard is only marginally better than Tiger even on Intel CPU's due to being dumbed down and bloated with legacy code. Losing the PPC processor and compatibility code will improve MacOS measurably.
Programs that won't run on SL, and machines that can't run it need to go away (make it into a fax server or contact management work station or something useful). As long as I can get to the machine on the network, it has value, just not for production.
Sorry, just wrote another chapter

What would happen if I turn off my backup and delete backup data From my device? Will it delete my music and everything for ever or just stay in the cloud but not on my device?

What would happen if I turn off my backup and delete backup data From my device? Will it delete my music and everything for ever or just stay in the cloud but not on my device?

If you have multiple devices backing up to the Cloud, you will see all of them listed. You would click on each device to change what is backed up from that device. You can then delete your individual back-ups.
Once you have all your settings to your liking, you can then go back to Settings>iCloud>Storage & Backup, and click on Back Up Now (bottom of the screen) to create a fresh backup with your new settings.

What should i do if my external hard drive is not detected by my mac

what should i do if my external hard drive is not detected by my mac?
need to have the files saved on it and be able to backup via time machine

Hi:
Here are some of the options I've read about on here that may or may not work:
1. Reset the NVRAM as it may need to be reset to recognize the drive. See below:
http://support.apple.com/kb/ht1379
2. If the drive is a USB drive, put a USB hub between the drive and the unit. As ridiculous as that may sound in some cases it works.
3. If you have some types of hardware problems and want to test them this works:
http://scsc-online.com/Scannerz.html
That's a test tool only. It isn't going to fix anything just diagnose a bunch of possible hardware problems and it costs money, too.
What format is the drive in? Is it a Mac native format like HFS or is it some other format, like NTFS or FAT?
