Previous system folders hav 10gb on an 80mb disk could not repair vol

I'm trying to install Virtual PC. It seems to hang and the reason I suspect is there isn't enough disk space. Can I delete the previous system folders? I shouldn't need them for anything I can think of. There are two of them 5gb each.
I have another problem I ran disk repair and it said one vol could not be repaired in red but it did say 1 vol was repeaired. I'm not sure what this means since there should only be one vol on my hard drive? When I ran disk repair I got the following messages:
Checking HFS+ vol
checking Extents overflow file
checking catalog file
Reserved words in catalog record incorrect data
checking multi-linked files
checking catalog hierarchy
checking extended attributes
Invalid leaf record count should be 6706 not 549
checking vol bitmap
checking vol info on Mac HD
Repairing vol
the vol was repaired
1 HFS vol repaired
1 vol not repaired
I have MySQL Server and PHP installed. I just upgraded from Tiger to Leopard. I need VPC to run and I need space to install Windows on the Mac HD but I'm wondering why disk repair could not repair 1 vol and why it thinks there were two volumns.
thanks in advance,

Is there a second partition for Virtual PC, or other use?
In Disk Utility, each partition should be listed below the main line (with the Drive name/size).
If there are two (or more) then you have multiple volumes.
The one named "Mac HD," that was repaired, is almost certainly your boot volume, so look at the other(s).
See what the format of each is, by clicking on it and looking at the bottom. If it's not some flavor of Mac OS Extended, then DU likely can't repair it.

What to do with Previous System Folders?

First of all, Happy New Year to all!
I just spent two days doing an "Archive and Install" on my iMac at the advice of an Apple Genius who checked out my iMac at the Apple store. He said my iMac was running very slow but couldn't find any reason for it.
The first "Archive and Install" took six hours on the 30th, and then it was several more hours to get the software back up to speed with all of the updates. But after all of that, my system ended up in the Kernal Panic screen on start up. So today I got on the phone with Apple Care and they had me boot up with the Leopard Install DVD in the drive, holding down the C key. That worked, but I was back to square one with my Archive and Install.
The second try yesterday took another 6 hours, and then it took several hours to get my software back up to speed again. The Apple Care guy told me the Install should only take an hour, so that right there tells me something isn't right. Anyway, here I am after two very long days, with my iMac at least functioning again, albeit not faster as I had hoped. It's still running slow as molasses. This post has taken me forever to write due to only being able to type three or four letters, then wait for SBOD to stop spinning, then another two or three letters. It's so frustrating.
But, my main reason for posting here is to ask two questions.
1. The two "Archive and Installs" left me with two "Previous System Folders" on my hard drive that are almost 21 GB's!! I had 74 GB's free before and now have only 53. Can I dump those folders and get my space back? I sure hope so. If so, how do I safely do it?
2. The three folders on my dock at the right end; Applications, Documents, and Downloads, used to be in nice neat folders with symbols on them indicating what they are, but now they're just plain folders with stuff sticking out of the top of them, and in the case of the Applications folder, the Address book app is sitting on top of the folder, rather than inside of it, and all I see is the Address book icon, not the folder. How do I get those folders back to normal? I hate the way they look now!
I'm very frustrated that I'm having all of these problems with my iMac, but grateful at this point that I extended my warranty before the first year was up. I'm definitely going to have to take it back in for more help. I don't think it should take four minutes for iTunes to start up and shut down, four minutes for iPhoto to shut down, or two minutes for a photo to open up in iPhoto after clicking on it, etc., etc. I have the Spinning Beach Ball of Death spinning way more than it should! I'm tired of constantly having to wait for it to stop so I can continue.
Ironically, I installed two more Gigs of RAM less than six months ago so that I would have a faster computer, but I never really noticed a difference. Although it wasn't this slow the first few months.
Thanks in advance to anyone who can answer my two questions up above, and thanks for listening to me while I expressed my frustration.

Hi Deb,
This may be ten days late, and way, way too long, but you might want to try some of these suggestions, especially if AppleCare, or someone else, hasn't fixed it for you. You'll probably need to print out all this stuff. It's all stuff I've found useful in similar situations. There is no particular order to check things, but you might want check the utility "Activity Monitor" first and then try setting up a new account. That has worked for me.
Launch "Activity Monitor" (found in the utility folder inside the root Applications folder) and click on the CPU column to see if some background process or another application is running and using a large percentage of the processor's time. Also check the RAM columns to see if something is using a lot of the available RAM. If there is something that doesn't seem right, you can select it and double click the questionable item - a dialog box will appear that allows you to quit. That may solve the problem of spinning "pizza wheels" of death without a restart. At the least you'll have a good question to ask AppleCare (though they'll definitely suggest Activity Monitor.
You may also want to set up a new account in Apple Menu/System Prefs/Accounts with a different name and password. Then within that account try launching some apps from the Root Applications folder. They may now work in the new account. You can also install some apps you use most within the new account. Those apps will be placed in the Applications folder within the new home folder of the new account - NOT in the root Applications folder (the one you see when you double click the hard drive icon).
If you haven't set up a new account before it will seem strange when you first startup. Nothing is the same - the desktop, dock, etc will be like when the machine was new. But often, using the new account, and finding the sluggishness is now gone, tells you the problem was in the old account - even if you can't find what the problem was. The old account is still there. But setting up the new account will take some additional drive space if you reinstall applications.
Whatever you do, *_don't just delete the old account_* as that will also delete all your documents, videos, photos, etc. You can copy or move between accounts with your administrator password. The Library folder in the old Home folder will contain a lot of stuff you may want to keep, but also can contain the corrupt file that caused the sluggishness problem. You may want to copy the contents of different User/New Acct Home folder/Library folders a little at a time and reboot after changes. If the sluggishness reappears, then pull out the last items you put in and try to narrow it down.
If you don't want to set up a new account initially try some of these suggestions. Uninstall and reinstall the major applications that run slowly. Use the uninstaller that comes with the app. If there is none, then just reinstall and restart. That might solve the problem. Reinstall whatever apps you need. Can't hurt and may eliminate some file corruption.
After you restart, and BEFORE you launch any application, press and hold the Cmd (Apple) Key and then hit tab. You will see which apps are running in addition to the Finder. If there is stuff you didn't launch, keep pressing Cmd-Tab which will highlight each application. When selected, you can quit the application [Cmd-Q ]. Or just release the Cmd-Tab keys with the app selected and it's name should appear at the top left of the menu bar. There, you can pull down the menu and quit it (or press Cmd-Q). If it doesn't quit try to Force Quit [Opt-Cmd-Escape]. Try not to quit the Finder. Then launch the apps you need and see if they are still sluggish.
If there was stuff running and you don't know why, check your Account (Apple Menu/System Prefs/Accounts). Accounts is the first item on the System row (next to last row down). Click Accounts and when it opens, click the the account you're using (if there are more than one). Then click the Login Items tab near the top of the window. You'll see a list of apps that launch whenever you start up (sometimes in the background). If you don't recognize some of what's there you can remove them using the [-] icon. You'll have to unlock the account with your password and then re-lock it to prevent others from changing stuff.
Restart or log-out and log-in and see if the machine is faster without one or more of the removed items. There are things that are best not touched, but you'll probably know by their names. Pretty much anything you'd add will be found in the Applications or Utility folders. Other stuff is added by applications when they are installed. Make a list of whatever you remove if you have to add it back. If an application needs something you removed, you may be asked to reinstall the app.
That's it - hope it helps.

Previous Systems Folders

I have 2 Previous Systems folders on my hard drive, each with an Applications, Library, private, System, and Users folder. Some are empty, but like the Applications folder is full of Mac software. These folders are in addition to the normal folders of Applications, Applications (Mac OS9), Library, System X, Systems Folder 9, Updaters, User Guides and Information, and Users.
Can I dump the Previous Systems folders and free up some valuable hard drive space?
Thanks,
Powerbook G4 Mac OS X (10.4.7)

You can, as long as you have verified all the data from the previous Archive and Installs that you want to keep has been moved over to the current Users folder, and Applications folder. That means checking your iTunes library, iPhoto library, and any documents you stored. Typically if you Save User and Network settings all of them should be moved over. If you ever didn't save User and Network Settings, it might be a problem. Also the contents of the Shared folder which AOL uses may not have been moved over, if you use AOL.
The quickest way to get rid of those folders once you verified all the data is moved over, is first to backup your data, and then use http://www.macosxcocktail.com/
Note, Cocktail is a multipurpose utility which should only be used for troubleshooting and forcing deleting folders when you are familiar with what you are deleting. A lot of its functions which some claim are good for maintenance may actually cause more damage than good if used at the wrong time.

Archiving "Previous Systems" folders (unsuccessful)

I have been trying to archive "Previous Systems" folders on DVD to get them off my hard drive where they're taking up space.
Every time I try to burn them to DVD using OS X's Burn facility or Toast, it starts to burn, but eventually says something along the lines of 'Some of the files could not be burned because you do not have sufficient privileges.'
I tried to compress them using OS X's .zip compress tool as well as just about every third party compression tool available, but got a similar message.
Does anyone know a way to successfully archive on an external medium (DVD) "Previous Systems" so they aren't sitting there taking up room on my hard drive?
Any help is appreciated.
-Mike

you should simply delete that folder once you know everything on your system works. there is no reason to keep it around or back it up.

I am an absolute newcomer to Lightroom. I have downloaded images from camera (OMD EM1) and divided them into folders. Some folders work ok in Develop mode. With other folders I get the words "This file could not be found". What should I do

As an absolute newcomer to Lightroom 5 I have downloaded images direct from camera (IOlympus EM-1) and divided them into folders. When I go into Develop mode, some folders can be developed ok , but with images from two other folders I get the message "This file could not be found". What should I do?

may i suggest opening the files in Olymous Viewer 3 and exporting them (you can do some editing there if you wish or not) asTIFF files. After that you can import the new files into LR. LR seems to like tiiff more than .orf files
The advantage to using OV3 is that it seems to do a much better job converting RAW EM1 files. Colors are more accurate ( my red flower pot turned orange when loaded directly into lightroom)
. The tiff files just LOOK better in LR after the conversion . there is a youtube on this subject and when i tried it myself i was impressed

Erase and Install
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Quit DU after formatting completes and return to the installer. Install Snow Leopard.
5. After restart into Snow Leopard download and install Mac OS X 10.6.8 Update Combo v1.1.

Disk Repair notified me it could not repair the HD. Iam to reformat the disk and restore backed up files. OS Utilities give me a "Restore From Time Machine Backup" option. I have not reformatted the disk; does this restore option do both?

Disk Repair reported that it could not repair the HD Disk. I am to reformat the disk and restore backed up files. OSX Utilities give me a choice of restoring from time machine backup (which I have on MyPassport) but no information on reformatting the disk, which I assume I have to do first. How do I reformat the HD ...or does the restore from Time Machine do both things?

Boot OS X Recovery and use Disk Utility.
If Disk Utility reported the disk cannot be repaired though, you should replace it with a new one.

How to remove preinstalled files of adobe photoshop from my mac mini so that i can install a new version of the same software.The previous version was removed using the app cleaner software.Could not continue installation bcoz of earlier files

How to remove preinstalled files of adobe photoshop from my mac mini so that i can install a new version of the same software.The previous version was removed using the app cleaner software.Could not continue installation of the new version because of the existance of files from the previous version.plz help

What "app cleaner software" ? I ask because installing Photoshop over a previous version has never been a problem. Perhaps your difficulty stems from another source, eg. "cleaner software" ?
If you look in your hard drive, at the root level there is a Library. In there is a folder called Application Support, and in that you will find a folder called Adobe. Files from your previous version are there.
However, I urge you to call Adobe support to make sure you are not doing anything that would mess up other Adobe applications.

Hiya,
The error is because the app tried to import that driver but it was not found. So, you will need
to recheck your project setup, provide locations for imports, etc. I am not familar with Intermec Printer.
The code snippet does not show any information about the DLL import, check there too.
Hope this helps. :)
