Dump Previous Systems and Damaged Files?

I just upgraded to Tiger (10.4.6) from 10.3.9. I have two new folders on my Finder now, Previous Systems and Damaged Files. As I have only 25 GB of an 80 gig hard drive left, is it OK to dump them?
eMac 1.24 GHz Power PC G4 Mac OS X (10.4.6)

With 25 GB remaining you should be in no immediate danger of filling the hard drive and killing the system, so you can take your time checking out 10.4.6 before you toss the Previous Systems folder. You can look it over and decide if there are any files in there you want to still use. That said, I kept the Previous System folder around on my eMac after updating for all of maybe three days, so yeah, you can toss Previous Systems.
I'd be more concerned about a Damaged Files folder. I've never seen thaat as part of an upgrade, it suggests there may be directory or physical disk damage. If you open Disk Utility, what does it show for your hard drive's SMART status? If you boot from the Tiger install disk and run Disk Utility> Repair Disk from the Installer menu, does it report any problems? What sort of files are in the Damaged Files folder?

Dumping 'previous system' folders - curious about time required

Hello - In an effort to free up disk space, I've dumped the 'previous system' folder (created during 'archive and install' operation). There were two instances of this, hence two prev sys's. There are 853,563 items to delete and it looks as though it manages to dump roughly 5,000 items per hour.
The math indicates that it could take about 170 hours to complete this process. Does that sound right?
Thanks.

Thanks for your reply. What you told me to do makes sense - I did as you said:
- Stopped the deletion of the prev sys's
- created a new untitled folder on desktop
- dragged two prev sys files from Trash into new unnamed folder
- created two new folders and named them 'precisely' as the old folders
- dragged them onto unnamed folder that contained the two actual prev sys folders
? was not asked for confirmation about replacement
? when I clicked on unnamed folder it contained the two new 'empty' folders plus a folder named "Previous Systems" that I didn't put in there. Within that folder were the two actual prev sys folders.
I tried moving them around - I tried creating a new desktop folder named "Previous Systems" and dragging the empties into that and then that into the unnamed folder. Was never asked for confirmation about replacement . . .
Any hints?
Thank you for your help.

Previous Systems and System?

When I highlight my Macintosh HD the folders all pop up... there is a previous systems folder and a system folder... does anyone know what the difference is between the two? I have a feeling that this previous systems folder with all the crap in it is taking up more memory in my computer than it needs to.

The Previous Systems folder contains files left over after an Archive & Install; it can safely be deleted after verifying that there's nothing in it that you want or need. The System folder is essential for Mac OS X to operate.

Archive and reinstall - can't find previous system and want to delete

Hey everyone,
I just did an archive and reinstall with OS 10.5 and now am running out of disk space. I've been trying to find the "previous system" folder but can't locate it with finder. Any ideas?
Is it in the system folder? What can I delete without killing my computer?
Noob here, thanks a bunch!

Current system is OS 10.5
previous was the latest update - 10.5.6?
I have about 10 GB less space now that I need to recover!
I'm running this: MacBook Pro 2.4Ghz, 2GB 15", 160GB
Thanks.

Immediate help can be only provided by Oracle Support Services. So if you need that, please raise a Sev1 SR . For your issue, as others have suggested already, if you have a valid backup and you are in the archive log mode, using RMAN's BMR(Block Media Recovery) , the issue can be resolved provided there is nothing wrong with the hardware of yours. If that's the case, recovery wouldn't yield any benefits.

File system and LR2 file system view summary

Hello,
Is there a way when navigating a directory via the Folders panel to click on the folder and get summary information about the contents of the folder both from a file system perspective as well as a Lightroom perspective?
file system perspective: number of physical files supported by LR2 in the folder
LR2 perspective: the number of files that have virtual copies, how many total virtual copies total, how many photos are in stacks, how many stacks, etc.
Thanks,
Matt

               No, you can't specify an entire filesystem as something to cluster. I
          suggest using NFS or some shared filesystem and then running a cluster
          off of that.

InDesign file crashing and damaging file...even the backup file.

Of course in times of deadline but I have a lengthy 20 something page document that continually crashes and then gives me a damaged error but attempting to recover just crashes InDesign. I have tried recreating a couple times thinking maybe something corrupt in the doc but even the back up file is corrupt now! UGH! HELP!!!

Hard to tell what you mean by the backup file is corrupt.
It's possible that only the recovery data is bad, and if you empty the (hidden by default) InDesign Recovery folder you will be able to start ID without auto-recovery, then use File > Open... to navigate to and open the last saved version of the file.
If a backup file is also misbehaving it may be that it already had a problem, or else there is something not specifically file-related that is the problem, a plugin conflict, or a bad font are two common errors. Without more information, though, it's impossible to say. What version of ID? Which OS? Do you have the latest patch installed for your version?
If yo are a Mac user you likely have a crash report associated with this. If so, post it on pastebin.com and give us a link to it here and we might be able to narrow things down.

Problems with installation of system and support files with Labview 5.1 on Windows NT.

I make installations disks with Labview 5.1 on Windows NT and I need to add some system files and other support files. When I'm in App Builder I choose them in "Add support files" and I mark their "custom directory destination" (c:\winnt\system32, c:\est\base) but, when I test the installation I see that files don't save in this directory, they save in 'C:\c\winnt\system32' and 'C:\c\est\base'. How can I solve this problem?

Jorge,
I know there were some problems with the LabVIEW 5.1 Application Builder that were fixed in the LabVIEW 5.1.1 Updater. I recommend you download that update to see if this fixes the problem. Also, double-check to make sure you have typed the file paths correctly. If you continue to have problems after installing the 5.1.1 updater, please let me know, and please attach your .bld file so I can examine it for any problems.
Thanks for your patience on this issue, and have a pleasant day.
Sincerely,

Adobe Premier Pro CS6 editing system and mov files

We have just installed a new Adobe Premier Pro CS6 editing system with a HP 820Z (running windows 7) 18 core multi drive system. Our production company has used many mov. files from Ponds. We were a FCP 7.0 studio (still have the system) but the mov files won't import to our new CS6 System... Not trying to import from the mac...have them stored on another PC. We depend on this stock footage for production. Do I need to download a converter? I just had to produce two spots with a still background because I could not get any of our stock mov files to work...
Thanks much for any help!

PP does support direct import of Quicktime files that can be played back on the system.
What is the correct error message after import?
Can you playback the files with the Quicktime Player?
For some codecs like DNXHD you have to install the quicktime codec first...

CREATING SYSTEM AND SYSAUX FILES

Hi,
when creating DB by script, can we choose to have them in AUTOEXTEND OFF or ON like this :
SYSAUX DATAFILE '/d12/ORA_DB/SYSAUX_001.dbf' SIZE 350M
EXTENT MANAGEMENT LOCAL AUTOEXTEND OFF
DATAFILE '/d12/ORA_DB/SYSTEM_001.dbf' SIZE 100M
EXTENT MANAGEMENT LOCAL AUTOEXTEND OFF
Many thanks

The reason why this command fails from the beginning is because you are using 'EXTENT MANAGEMENT LOCAL' right after the datafile size, then you declare the autoextend on clause, this autoextend on is a datafile attribute, meanwhile the extent management local is a tablespace attribute which cannot be declared until you have completely specified the datafile:
SYSAUX DATAFILE '/d12/ORA_DB/SYSAUX_001.dbf' SIZE
350M
EXTENT MANAGEMENT LOCAL AUTOEXTEND OFF
DATAFILE '/d12/ORA_DB/SYSTEM_001.dbf' SIZE 100M
EXTENT MANAGEMENT LOCAL AUTOEXTEND OFFSo, the command, properly rearranged, to create your tablespace is:
SYSAUX DATAFILE '/d12/ORA_DB/SYSAUX_001.dbf' SIZE 350M AUTOEXTEND OFF
EXTENT MANAGEMENT LOCAL
DATAFILE '/d12/ORA_DB/SYSTEM_001.dbf' SIZE 100M AUTOEXTEND OFF
EXTENT MANAGEMENT LOCAL ~ Madrid

HT1710 If I click archive and install and it says moves existing system files to a folder named previous system , will this save my photos tol

I have to restore my Mac mini and i want to click on archive and install and it says it will move existing files to a folder but I need to know wether my photos will be moved too because I have 5 years worth of photos on there. If my photos will not be moved could I take it too a store and they could put them onto a USB stick for me.

"Archive and install" is an option in early versions of OS X installers. It moves some parts of the previous system to a folder called "Previous System" and installs the new OS.
There is also an option to presever user data and settings. See this document. http://support.apple.com/kb/ht1710
If you have 5 years' worth of photos and you do not want to lose them, then you NEED to have a backup. Hard drives can fail. Suddenly. Particularly on aging hardware. Computers can get stolen, set on fire or have drinks spilt over them.
If you do not have a backup, you should EXPECT to lose your files.
You should not need a store to make a copy of your files. Get an external drive, or use DVDs and move the files in the Finder. If you're using Leopard already, then you have Time Machine.

Missing disk space and deleting "previous systems"

Hmm.... I have an 80G hard disk on a 2006 Macbook intel core duo and cannot load any more updates / applications because MAC OS tells me the disk is nearly full (2G spare). However, I can only find 40G of stuff on there including all the big ones such as music, movies, photos, docs, apps, system, previous systems and library.
1 - is there anything I need to do (other than delete stuff) to find or free up the space?
2 - my previous systems folder is 10G - can I delete this without causing damage?
Any thoughts appreciated!
Andrew.

Hi Andrew;
The Previous System folder was created when you did an Archive & Install some time in the past. If everything is working correctly since the A&I then you can delete the Previous System folder.
Running your system with only 2 GB of free space greatly increases the chances for file corruption. I would suggest that you boot form the install media and repair the the system disk with disk Utility.

Can I restore my IPADs operating system and dump IOS7?

Like millions of other faithful IPAD owners, I too updated my system to ios7 last Wednesday. Immediately following the update, I no longer was able to operate many beloved apps. Can I restore my previous system and dump the ios7?

One of my favorite apps was Dish Network for IPAD. After the ios7 update, I was no longer able watch movies. Other apps such as PBS won't run either. I use some things on Dish and PBS for educational purposes in the classroom so the update has interfered with my personal and work usage. Any ideas would be appreciated.

Please help restore DMG missing partition and access file vault.

I am quite emotional at the moment, if anyone can help me access my files, pictures of my baby daughter and important documents.. I would be extremely grateful and willing do make a donation via paypal.
I have a 160 GB hard drive, which was partitioned as 30GB Spare and 130GB with my operating system and user files, including my filevault user directory.
My computer was downloading movies which filled up the 130GB partition, most of the 130GB is contained in my personal filevault user directory, my computer became very slow and unresponsive and i tried to free up space by deleting files which i no longer needed.
The machine became slow and un-responsive and required a number of forceful shut downs and restarts until the machine would no longer boot up, I inserted the OSX CD and attempted to boot from CD and use disc utility which now only displays my 30GB storage space, I was forced to install OSX on the remaining 30GB partition.
Now running OSX on the 30GB partition i used DISK DRILL to scan my hard disk for the missing 130GB partition which it did and i was able to save this as a DMG file to a external hard disk, now i am able to get this DMG to mount in the OSX i am running on the spare 30GB space, however i am not able to access the majority of the data inside the file vaulted user account.
I would like to know, would it be possible to restore the missing partition, as it remains on the HD but seems to be hidden.
Or is there somehow i can login to the user account on the mounted DMG ?
I am not very familiar with using terminal and would be extremely grateful for any advice or support leading to the recovery of my files.

Probably not.    You've now deleted the partition. It was probably useless anyway, though.
When i run disk drill or other disk recovery tools i am able to see the partition including including the files and my personal sparsebundle.
But you can't open the sparse bundle, much less see any of the files inside it, right?
Since you've already recovered the (probably-damaged) sparse bundle containing your encrypted home folder, you'll have to work with it.
I'd strongly recommend making another copy of that on another external HD and putting that "on the shelf" before doing anything else to it.   I suspect you have little chance of recovery, but don't take the risk of further damage.
You haven't answered my earlier questions:
Have you tried to run Repair Disk on either the original or copied partition?
If that doesn't help, this might: http://www.thexlab.com/faqs/fixfilevault.html
Do you have Time Machine backups?
Obviously, now that the partition has been deleted, you can't run repair disk on it, but try it on the recovered disk image.
You need more expertise than either Christopher or I have. Since Apple no longer uses "legacy" File Vault, it will be more difficult for them to help, too.
Is your Mac covered by AppleCare? If so, give them a call.
If not, your nearest Apple Store Genius Bar might be able to help: http://www.apple.com/retail/geniusbar/
Or check for an Apple Authorized Service Provider: http://support.apple.com/kb/HT1434?viewlocale=en_US
If not, one of them may know of an outside service than can help. That will be quite expensive.

Previous System

Under MacintoshHD I have a folder called Previous Systems and inside that System I. It takes up 2GB of memory - can I ditch it without harm? Thanks Ron

the Previous System folder comes from having done an archive and install of the syste,. most likely the 2 Gb in the System folder are swap files or virtual memory which can be deleted with impunity, but (assuming you did the archive and install) it's worth looking to see.
