File level clone of boot drive leaves extra folders, can I remove or hide?

I made a file level drive clone with DiskUtility and then again with Carbon Copy Cloner (to confirm behavior) in preparation to go from 10.5.1 to 10.5.2 and found extra folders on the new copy.
dev
home
net
These folders are in addition to the usual app, users, library etc. They appear to behave like /etc and /var in that there is not a folder for them on a non running OS boot drive. They claim to be empty. Can they be deleted, hidden, turned invisible? Advice?
Thanks.

Kostas is correct. These folders are used by the system, and will be hidden from the users when the disk is running as the current system.

Mystery files clogging up my boot drive!

I just got a message that my startup disk is nearly full. That was a surprise. When I did a "get info" on the four folders on the drive, Applications, Users, System and Library, the amount of space used adds up to about 75 GB. But when I do a "get info" on the boot drive that houses those folders, it says 115 GB are used. The boot drive is a 120 GB Mercury Elite, and I store the majority of my pictures, data and music on another internal drive.
How do I figure out where these "mystery files" are that are clogging up my boot drive?

Surely you can shrink and create a 160GB partition and you have in the past done both? Or use the partition you have. I like to have "current" or working image, a backup from pre-10.8.3, an image from 10.6.8 etc
use CCC or Disk Utility to make a clone or sparse disk image.
Restore image with ERASE and RESTORE.
In future use Disk Utility and it will see that TRIM is present and DU repair disk will perform a trim operation - you will see output on screen at the end of a repair.
Head to the developer home page for TE.

What's the best way to clone my boot drive?

I just bought a new 500GB drive for my G4. What's the best way to clone my boot drive?
Is there a way to put the new drive on the buss as a second drive and then copy everything from my boot drive to the new drive? How do I make the new drive bootable?
Or
Do I have to install OSX on the new drive, put the old boot drive on the buss as a second drive and migrate everything to the new drive with the Utilities Migration Assitant program?
Are there programs available to make this easier? Where & how much?
Thanks for any help I can get.

bamim2:
Dr. Smoke's FAQ Backup and Recovery has excellent advice on developing a backup strategy.
You already have a larger extrnal HDD (Hopefully it is firewire?) The next step is to format and partition the HDD. (see step-by-step below). And thirdly you will need a good cloning utility. Carbon Copy Cloner has already been suggested, and the latest version is excellent. I, personally, prefer SuperDuper for its ease of use and efficiency. Both are great tools and relatively simple to use.
I mentioned the hope that you have a firewire. One of the wonderful benefits of using an external firewire HDD for backing up is that you can make a bootable clone. This gives you an emergency boot drive in case of a problem. It also gives you an external device for running diagnostics and repairs from the extnernal to the computer and vice-versa.
Congratulations on taking the first step toward securing your computer and your data!
Formatting, Partitioning Zeroing a Hard Disk Drive
Warning! This procedure will destroy all data on your Hard Disk Drive. Be sure you have an up-to-date, tested backup of at least your Users folder and any third party applications you do not want to re-install before attempting this procedure.
Boot from the install CD holding down the "C" key.
Select language
Go to the Utilities menu (Tiger) Installer menu (Panther & earlier) and launch Disk Utility.
Option for formatting an External HDD
Connect external HDD to computer
Turn on external HDD
Start up computer and log in
Go to Applications > Utilities > Disk Utility and launch DU.
Select your HDD (manufacturer ID) in left side bar.
Select Partition tab in main panel. (You are about to create a single partition volume.)
Select number of partition in pull-down menu above Volume diagram.
(Note 1: One partition is normally preferable for an internal HDD. External HDDs usually have more than one. See Dr. Smoke’s FAQ Backup and Recovery for tips on partitioning external HDD
Note 2: For more partitions than one, after you have selected the number of partitions you can adjust the size of the partition by selecting the top partition and typing in the size; then move down if more adjustments need to be made..)
Type in name in Name field (usually Macintosh HD)
Select Volume Format as Mac OS Extended (Journaled)
Click Partition button at bottom of panel.
Select Erase tab
Select the sub-volume (indented) under Manufacturer ID (usually Macintosh HD).
Check to be sure your Volume Name and Volume Format are correct.
Optional: Select on Security Options button (Tiger) Options button (Panther & earlier).
Select Zero all data. (This process will map out bad blocks on your HDD. However, it could take several hours. If you want a quicker method, don't go to Security Options and just click the Erase button.)
Click OK.
Click Erase button
Quit Disk Utility.
Good luck.

Possible to use TC as clone of boot drive in Leopard?

Time Machine seems to take FOREVER whenever I run it, so I end up not running it. I was wondering if it is possible to use Time Capsule as a pure hd and clone my boot drive to it for a full backup option? If so, how? Are there reasons not to?

Bad sectors automatically get re-written when new data are supplied. If the new data don't "stick" a spare will be substituted.
If you are happy with your clone, just update it. There is no need to write Zeroes to it. I was suggesting that process for when you make major changes -- it takes several hours to complete.
You may prefer to use you smaller drive, Zeroed, to start a new clone, wait a little while to assure success, then start a Time Machine backup set on the larger Iomega.
Or some other approach that has not occurred to me.

Copy/Clone of boot drive

Hi.
I've just picked up a 1.5TB drive that I'm planning on sliding into Bay 1 to make it my new boot drive.
Is there an OS X native way to clone my current boot drive so that I can just swap the drive over and I'm good to go?? or is CCC the only way to do it? I'd really like to make it as simple and painless as possible.
Thanks

superduper by far in my experience is the best.
however, id be really wary about those Seagate 1.5TB drives right now.
there seems to be alot of complaints on various PC and Mac forums that theyre unstable.
not trying to scare ya, just thought id give a heads up!

I have an iMac 2013 running OSX 10.9.4. I want to use Carbon Copy Cloner to backup user files to an external hard drive to free up space on my iMack Hard drive.
So, say I make the backup today, delete iphoto libraries from my iMac, and then backup my iMac in a week. What happens to the iphoto libraries that are on the external backup drive now that I am backing up the iMac where they no longer exist?
I will have them backed up to a separate second external drive as well.
I'm just very cautious about removing them from the hard drive.
Thanks for helping and understanding my crazy caution!

I'd like to store my Aperture /IMovie Libraries on an external hard drive.
That is fine and recommended.. use the fastest disk you can afford.. ie Thunderbolt>USB3>FW800>USB2.
In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives.
Let me be clear.. you want to partition the one disk.. use it for TM and move your files to the external disk.. and then backup to the same disk.. You can do it.. but that is not a backup.. that is an experiment in how long you can get away with running files and backups on the same disk before you lose everything.. like Russian Roulette.. pull the trigger enough times and laws of probability will do you in.
You must have backups on a different disk .. otherwise it is pointless.
Can I set up a RAID 5 format for redundancy?
No.. you can buy special USB and Thunderbolt external drives that support RAID..
BUT that is still not a backup.. let me show why.. you make a silly move and corrupt your file in aperture.. it is not that rare.
Raid will corrupt all copies of the files.. it is replicated across all disks.
Delete a photo it is deleted across all disks.. you have no recovery.
Alway, always consider RAID system one disk.. backup onto another disk.. and if the photos or movies are at all important to you.. ie your family .. make another copy and store in a relatives house.. There is no such thing as too much redundancy.

I can not upgrade from 10.2 to 10.6 because of missing "itunes.msi" file. How do I repair it? I can not remove itunes and start over.

I can not upgrade from 10.2 to 10.6 because of missing "itunes.msi" file. I can not delete ITunes and start over either.

Download the Windows Installer CleanUp utility from the following page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
To install the utility, doubleclick the msicuu2.exe file you downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

Why are my render files in my boot drive/root directory?

I have configured FCP to use an external drive for my Scratch Disk to render Video Capture, Audio Capture, Video Render and Audio Render as well as the Waveform Cache, Thumbnail Cache and Autosave Vault. Plenty of room on it and for the most part, I see a lot of render files on it, just like it should do.
However, if I leave FCP running for a while, it will start to auto-render again and does so placing tons of huge files on my local boot drive right on the root directory under a folder called "Render Files". It ends up filling up my boot drive every time and need to delete them.
I have searched everywhere to find where to configure this to move it to my scratch drive, but no joy.
How do I get FPC to render these files on a non-boot drive scratch disk?
Thanks.

That's possible that's it going to sleep. But I don't think so. The problem happens when I let the editor sit too long without doing anything in it (get up for a cup of coffee, using another application to generate some text effects, etc). Then its starts rendering on its own and does so only with the local boot drive/root directory.
When it comes back, the "green line" (Preview Render) is gone and the lines are replaced with dark blue, which I think indicates the sequence was rendered in the highest possible res/codec I have selected. That's fine, but why does it insist on using the local drive when I have another specified?

New boot drive question

I'm looking to replace my 250G boot drive with a 1T; Can I use SuperDuper or CCC to move the OS and applications to a FW drive & boot from that? I'm confused about starting up after replacing the boot drive. Thanks for any confidence you can give me

Hi. You can clone your current boot drive to an external FireWire drive and then boot from it - and then install the new internal drive, and clone the system from the FW drive back to the new internal drive. Or install a new system on the internal, if required.
You should make sure that any other FireWire devices are disconnected during cloning. You should also run Disk Utility > Verify Disk and Repair Permissions on the internal before you clone.
You should check that the boot from the FireWire works a few times.
You can select the boot drive before you Shutdown in System Preferences > Startup Disc - or boot holding down the Option(alt) key and select the Startup drive from those offered. Patience may be required, as it's a bit slow to find the boot drives sometimes.
Good Luck.

New boot drive - Photoshop will not launch

I recently cloned my boot drive onto an SSD, which I now use as my boot drive. Everything works fine except when I try to launch Photoshop, I get an error that says, "Could not intialize Photoshop because the disk is not available."
I have both CS6 through Creative Cloud, and CS5. Neither will launch and both give the same error message.
I tried searching for a similar problem on the forum, but I didn't see anything. If this has already been addressed somewhere, please point me in the right direction. Otherwise, any suggestions would be appreciated.
I am running Mac OS X 10.8, and I've repaired permissions several times on my new boot drive.
Thanks.

You could try resetting preferences by starting PS and immediately holding down Cmd + Option + Shift keys. You should get a reset window.
Some users get in trouble when files are moved from default settings after installation. Also, Bridge will not work if temp file is not on boot drive.
Don't know how the cloud works. Think it is installed on computer? If so if above does not work unistall and re-install might be next step.

Possible to convert a mirrored RAID boot drive to a single disc boot drive

hi ... i made the mistake of installing my Macpro with a RAID on the first two drive bays as a startup disc. Although this doesn't pose any problems per se i would like to have a single disc startup drive now but i do not have the time or courage to re-install and re-configure everything (installation&config with all software takes 3 days due to the huge number of software i have on this machine).
is it possible (and how) to get rid of the RAID and convert one of the discs to a normal startup volume so i can reformat the second disc and use it as a work drive ? Since the 'mirrored' drives both contaion a full startup drive this should be possible i think but could not find any info on this.
thx for any help with this ...

hey .. funny how expert opinions vary ... i have a handfull of IT and software RAID experts who disagree with you ... in my case, i'd rather get rid of it ... ( however i still have to find a solution to clone my boot drive that works flawlessly with all my software ... )
anyways ... how exactly do i go about splitting the RAID, to make sure i don't mess it up ....
1. restart from CD
2. Delete the mirrored RAID set
3. remove one of the HDs with the raid slice on it (i'll keep it as a backup 4 the moment just in case)
4. restart from the remaining slice disc
5. ... ?
do i need to do anything specific ... ? what about the name of the Volume .. for the moment my startup disk (the RAID) is called 'BootRAID' ... the slices are called 'RAID Slice (disk0s2)' and 'RAID Slice (disk1s2)' .. in order for everything to work properly, don't i have to rename the new startup disk ?
i'm scared ...
here's a screenshot of my setup: http://kinkajou.net/diskUtility_RAID.jpg

How can I partition, clone the boot disk, no cd?

How am I going to partition my boot disk? I only have the OS that came on the hard drive, no cd.
Tried start up c key on tiger 10.4 but it did not start from that cd where I thought perhaps I could administer this partitioning.
And further, how can I clone once done, no cd.

Let me see if I have this straight:
You want to partition your boot disk. That's it right?
All you need to do is clone your boot drive to another partition, disk, external, etc. You can use either superduper! (recommended), carbon copy cloner, or even just use osx disk utility.
http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html
http://www.macupdate.com/info.php/id/7032/carbon-copy-cloner
Once you clone your boot drive, make sure it boots up first. Then if everything is good, re-partition the boot disk (erase) into however many partitions you need in Disk utility.
Then boot up from your clone you just made, open for example superduper, and clone back to your new partitioned drive. Bootup from the new partition drive, and you are set.
You don't need the CD to partition or even clone using DU.

Does iTunes match need to locate the actual files or just see its record in your library database? I am currently traveling in US and I have US and Australian iTunes accounts. But all my music files are on a hard drive in Australia.

Does iTunes match need to locate the actual files or just see its record in your library database? I am currently traveling in US and I have US and Australian iTunes accounts. But all my music files are on a hard drive in Australia. Can I start using itunes music match while I am travelling without the actual music files attached to my itunes?

In your situation I strongly recommend you read over that KB article. The international iTunes Stores are not cross-compatible.
My understanding of how it would work is that when activating iTunes Match on your US Store account, any songs you have in your iTunes Library that were purchased from the AUS Store account will NOT be matched. As I understand it, those files will be uploaded (which means you need the files on a local HDD). I also do not think it is possible to have iTunes Match active on more than one store ID on the same computer. But since iTunes Match is not available internationally yet, that point is moot for the moment.
To be honest you might want to wait until the service is available internationally so you can guage how will it will serve you.

Two Boot Drives possible?

Hello. I want to know if I can buy a small second hard drive and install windows on it and boot from that drive as well? I only want it for a video game.

Can't tell by your signature but it looks like you have a Mac-BOOK-Pro and this is the Mac_Pro___ forums so the answers vary accordingly.
From what I understand, Windows will NOT install on an external disk. So you would have to install it via Boot Camp onto another partition on your Mac boot drive. OR, you can replace the DVD drive and install another drive there and do it that way also. Search the forums for the different ways and which ones to use, HD or SSD.
Suggestion:
Replace your internal HD with a 1T HD or larger then partition the Windows part for 100gig and buy a cheap external housing for the old HD and use it as your backup ddrive?
There are instructions on different ways to install it on an external drive on Yahoo/Google but it's not supported by Microsoft.

When I back up on my exertnal HD drive with time machine can I erase what on my computer HD for more space?

When I back up files on my exertnal HD drive with time machine can I erase what's on my Mac HD for space without losing what's on external HD?

If the data is valuable to you, redundant backups are essential. Time Machine is an excellent vehicle when you have to restore data that no longer exists on your internal HDD.
Mende1's suggestion of using Carbon Copy Cloner is excellent because it gives yous a HDD that is 'ready to go' should your internal HDD fail (as all HDDs eventually will).
For example, I have 5 copies of my iTunes folder, one each on three MBPs, on a HDD devoted strictly to iTunes and Time Machine (this does not include the iPod). One may view this as excessive but since I have over 100 GB in this application, I am very comfortable with this.
I advocate that the best backup strategy is Time machine combined with a boot HDD and a third HDD for the most important user data. If there is non essential data, the you may certainly compromise and use just Time Machine.
Ciao.
