My internal HD is partitioned. It was done by the Apple Tech guys when I bought my Imac 25". One section of the HD  is called 'Admin" & the other "Data". The guy said it was a good idea to do this, however I've runout of space on my "Admin" section (the HD was split 50/50). I now want to install Lion but the Imac is saying i've not got enough space. There's no even enough to install software updates.

I've googled  for instructions but I can't "unpartion" using Disk Utility  because I'm being told "This partition is the Startup disk, it cannot be erased". I've therefore come to a dead end. What do I do?

I back up to an external HD using Time Machine.

Also can someone tell me what files you should normally have in an "admin" partition. I seems to have all sorts of files in it. Can I just drag those files over into my "data" section & then delete the file in "admin"?

    The advice you were given was not particularly good, you had no need to partition your drive, all data can be written to the whole drive, an admin partition is nonsense..  I suggest you reinstall your OS, then resore from Time Machine, that will give you the whole drive to use.

    I agree with Miriam, what you can do is either change the size of one of the partitions - or delete it.

     

    To resize (or delete) an existing partition without losing data, you will need to use, for example, iPartition:

    But it is not free.

    Oh, my dog! The 'geniuses' told you to do it? Unbelievable! That's a Windoze thing and completely unnecessary on a Mac. Macs actually run better without partitions.

     

    The best thing for you to do is to back up all your data, boot from your restore disc, open the disc utility on the disc, remove the partition, reformat the hard drive and start again. Do you have a Time Machine back up you can use to restore your machine after reformatting the hard drive?

     

    Just note that, none of your older software will run in Lion.

    Debatable, while the info on solving the OP's issue is appropriate. I've always partitioned my HDs, since that's the only way to run multiple OSs and installers.

    Yes, of course! I have mine partitioned with BootCamp to run Lion. But, this machine was set up to keep data on a separate partition, which only slows down Finder.

    Never have seen the issue, but then I've never tested speeds. Most things just pop up. I have data volumes, volumes with disk images, and volumes for restoring the OS. Can't say any cause any slowdowns.

    Me neither. In fact logic dictates that, wth less 'baggage' to carry, it should speed up the finder.

    Until you search or use spotlight, then there is a marked difference. It is the same as having hundreds of files on your desktop. Finder will search the home folders first.

    You should never have hundreds of files (or indeed any) on your desktop!

     

    I use Easyfind - so much better than Spotlight.

    More FUD. Matt Neuberg in a Tidbits or MacInTouch posting stated:

     

     

    It "used" to be the case the desktop icons were implemented as windows in Mac OS X, so that a large number of icons on the desktop did in fact mean a heavy resource usage and a drop in performance (it could even result in spinning beachballs). But that implementation was changed completely some revisions back (I think it was Leopard), and now it doesn't matter at all how many icons you have on your desktop.

     

    BTW, Spotlight works fairly well if you use a tailored SavedSearch—still won't find everything, but I've filed a bug report against that failure.ss4.png
