Intel Mac :: Can Use A 24" AHT Disc In 20" To Check Hard Disk
Apr 2, 2012
I have a 20" mid 2007 iMac I would like to upgrade to Snow Leopard. My problem is I would like to do a clean install but before I erase my hard drive I would like to make sure it in good shape. I found my AHT disc and found that the version number is 3A127 is for a 24" iMac. I don't know why I have the wrong disc. Is it usuable in the 20" iMac?   Â
I've download a Seagate Diagnostics programme to check whether my external Seagate FreeAgent Desk is working properly or not. However, when I run the programme, it indicates that cannot find the disk.
I have had a problem for about a month whereby my MBP won't shut down, it just hangs after it has cleared the desktop and only the wallpaper is displayed. Now disk utility won't see the disk at all, and Software Update also does not find any updates. It checks for new software for ever. My mac starts up fine, and I can use it as normal.
So my MBP was really making horrible clicking noise and I figured out that my start up Lion OSX disk partition is corrupted. I have three partitions. One for Lion OS X, another for Documents and another for Movies and Downloads. When I run disk utility and verify other two partitions(documents and movies/downloads), they appear to be okay but when I do the same with Lion OS X then it says:Â
The volume Lion OS X was found corrupt and needs to be repaired.Error: This disk needs to be repaired....then use Disk Utility to repair this disk. Is my hard drive gonna die soon? Or will it be okay if I just format my 500gb hard drive completely and install the fresh copy of Lion OS X again? I don't have a recovery disc or what so ever provided by Apple anymore. I have a DMG installation file of Lion OS X and a USB flash drive(4 GB approx). How can I repair the disk partition without the recovery start up disc? Â

My 27inch iMac has suddenly started writing to hard disc at 1.6MB/sec continuously according to Activity Monitor. Very noisy, and slowing computer down.. Cannot establish what it is writing or why. No virus (never been used for internet).
Using OS10.7, my hard disc is full. When I go to "About this Mac - Storage", it shows that it is entirely filled with "Other". Does anyone know what "Other" is so that I can delete some of it?
Recently I noticed that if I run Check Disk in Disk Utility, all the process works correctly but at the end it doesn't tell me that everything is correct (in green).
On the contrary, if I run it in recovery mode, (reboot w cmd-r), it works correctly to the end with the correct green result at the end.Â
a program that allows you to check a disk against a image after you initially burned it? I have a disc that has gotten a few scratches on it, and I want to verify its all ok.
On my previous OS version I simply clicked the activity monitor to see how much disc space was used and how much was available? I can't find that function now.Â

So my brother was upgrading to Snow Leopard from Leopard tonight...and during the install, the time remaining went negative, then shortly thereafter everything froze up so he was forced to power down and since then nothing has been right. He can't restore from backup because apparently there isn't enough space on the disk, then we tried to repair persmissions, it says it cannot and to reformat hard drive...so we do that, reboot and then try to re-install leopard only for now, and when it comes up to choose a destination drive he is just a blank box, his hard drive doesn't show up!
In trying to repair my hard drive, which disc utility said was corrupt, it stopped repairing it because it could not unmount the disc?I booted my macbook pro from my backup hard drive.
Mac Mini but there appears to be some changes on the layout out since my Mac Mini 2009 model. I am trying to see where the software Logic is set up or stored. And I cant find even how to get to Library.Its like its all changed. When I go to Finder (is this library?), under devices all I see is a Firefox icon and my External Hard Drive.But where is the main drive within the mac?? I used to be able to drag an Icon for my hard drive, ex hard drive to the dext top and it wont let me.Â

My hard disk has been indicated as saturated for the past weeK. Despite the fact that I freed Space (90 Gigas of movies) the next day when I opened my mac the Hard disk saturated warning comes up, and when I read the information on the hard disk; effectively there are 0 octets available. It is as if someone is using my computer to store data.
I haven't downloaded any new files and I haven't been working on any stuff that requires huge amounts of space. The situation is that even if I want to save a letter or any small file I have to make space simultaneously. I tried going into preferences to see if there are any malwares installed but it won't open, another thing is that 'mail' no longer downloads my emails so I have to consult them directly on Gmail.
I would be most grateful for any advice or informationon haw to solve this problem,
I am in need of some cleaning up of my hard drive. Here is what I have done so far. I purchase a 2 TB hard drive, I also have a 500 GB, both external. I have created 2, 1TB partitions. One is for the time machine and the other is for my music, imovies, large artwork files and random documents. Now that all of that is off of the internal hard drive, I need to clean up the dirve do that when I look at the drive, it doesn't say 2 GB available.
Gray screen and 'prohibited' logo appeared today without apparent reason.Forced a power down by holding power button. Restarted....eventually reached user login screen but froze again on login attempt after password entered.
Restrated again by forced power down but only got gray screen and spinning gear.
Have now spent many hours going through most conceivable options including...
following instructions on http://support.apple.com/kb/TS2570 re gray screen troubleshooting
have disconnected peripherals; reset smu, smc, and pram;
safe boot w shift key did nothing; Â
safe boot shift+v produced a screen of text that got as far as com.apple.launchd 1
but then several lines of text appeared repeating twice eaxctly same, each headed by disk0s2: I/O error. with [ErrNo 5], then
dyld: Library not loaded:Â Â and Reason: no suitable image found
final line ends with The System bootstrapper has crashed: Trace/BPT trap:5Â
I have tried installing from the original install disk several times but holding C key or Option/Alt key or D key gets no response and I cannot get the install disk to eject either holding down mouse button, eject buttonÂ
I haven't done any recent upgrades or installed new software, no new peripherals attached.
Is this a dead hard drive or does someone have other suggestions that might work?
My hard and back up disk both failed on the same day, strange but the kids were on the computer and things happen.Running Mac OS 10.6 I paid $800 to "super geeks" to recover the pics > 30,000 (many duplicates)I will receive a 500 gig external drive from them today via Fed Ex with the pics recovered . My plan is to move them to my iMac (had a new HD put in) but I do not want to transfer 30,000 pics priorto running duplicate annihilator & thumbnail annihilator on the new external drive. Is there an easy way to do this > looking for help?Can I run the programs on the recovered drive I will receive today prior to my transferring? Or is there a more efficient way of doing this.
I got an OCZ Vertex 2 120GB SSD and it runs fine and it's fast when using the computer. But the boot up time is so ridicules slow, slower then my old 500GB 7200RPM drive. My boot up time is around 37 sec with the SSD. The Apple logo came's up and the spinning wheel spinning forever!.
I think I know what the problem is, it's searching for like 25 sec for the first boot drive, and it can't find my SSD. Other people I know here on Macrumors just checked the SSD in the "Start up" in System Preferences and reboot, then they getting fast boot time. When I check my SSD and press reboot, it's still slow and when I later check the Start Up disk, none disk is selected (neither the SSD or "Network startup"...
Here is how it always look like when going in to System Preferences -> Startup Disk after a reboot, none is selected... (sorry for the Swedish language, I hope you will understand)
What should I do to fix this problem? (I've tried to reset NVRAM, PRAM and SMC, but with no luck).
I have Mid 2011 iMac of 500GB hard disk capacity. Is it possible to add/increase the hard disk capacity internally, say add another 500GB or replace it with 1 TB drive?
I had to power off my iMac by Pressing the power key and holding it several times over the last few weeks. The last time it wouldn't reboot - I'd just get an apple icon. When I tried a safe boot I'd get the icon and it would change to a no entry sign.Next I started up from the snow leopard installation disk with the intent of repairing the iMac disk. The installation disk worked but when I opened disk utility it only found the installation disk. It didn't find the iMac disk.
A hard disk icon started appearing on my iMac yesterday at log in. I have also started having error messages appear about random software or hardware e.g. error message advising mouse is not connected when it clearly is.
I have searched and googled in different forums and found this issue but never found a good resolution or explanation. many of the posts were related to 2009 or around that time. since yesterday I started to hear a noise like clicking or something (it's a hard disk noise that we all know and have heard) from my hard disk. I have no clue where it comes from. my mac is absolutly idle and no huge process or I/O is going on. its happing once in 10 minutes maybe. Well, I want to start observing it on when exactly it happens! but to me it should not happen!
By mistake I now have two Skype volumes on my hard disk. As soon as I click on the icon on my desktop the 'Trash' is changed to an eject icon. Trying different methods all result in some message preventing the delete option. I also have similar difficulties deleting a downloaded GraphicsConverter app.
The problem is that the mac will not boot period.When I press the Option on start up, it takes me to a screen where I could select to boot from the Macintosh Hard disk or Recovery 10.9 disk.Choosing either of these still does not boot up the computer.Â
I think that the hard disk is damaged but what I do not understand is why I can still get the option to choose the Hard disk or the Recovery disk.I am waiting to hear from Apple Support on when I can take my imac to the genius bar and I was wondering if there is anything I can do before then. Intel imac 27-inch bought refurbished in November 2010 with imac apple care.Intel quard core processor, 4 Gig RAM, 1 terabyte HDÂ
