Mid 2007 iMac SSD in optical bay - cannot write to last block of device

Hi All,
I've just replaced my optical drive in my 20" mid 2007 iMac (Dual core, 2.4 Ghz, 2 Gb RAM running Mavericks) with a solid state drive (Crucial MX100). The plan is to transfer my boot disk to this drive while keeping my 1 Tb HDD for media and such.
I followed the ifixit guide and it all went smoothly, however when I try to partition or erase the new SSD using Disk Utility, it tells me "Operation failed - cannot write to last block of the device". After googling, I found some answers here that suggested the optical bay cable may be faulty, so I bought a replacement and swapped it in, but no such luck, same problem. I also saw some threads suggesting that the boot disk should be in the original hard drive spot, but since this isn't the boot disk (yet) this shouldn't be the issue.
My computer recognizes the new SSD but won't allow me to partition it. Any suggestions on how to proceed?
Thanks!

OK. If that's the case, I'll just get another disk.
Lots of problems with that hybrid drives on Mac's on these forums, get another one that's 7,200 RPM and from Western Digital, not Seagate.
With a 7,200 RPM you get more performance across the entire drive, not just what's cached in the small flash portion of the hybrid.

1. Hybrid drives: I'm on number 8 in 6 different machines, no problems at all, what happens when you try?
2. The OP is not using a Hybrid.
3. Lot's of problems with WD drives not booting on these forums though.

I have a mid 2007 iMac and the internal superdrive audio cd won't play, the DVD works. Can I purchase an external cd drive that will work with my iMac?

I have a mid 2007 iMac (Model A1224 iMac 7,1) and the internal superdrive audio cd won't play, the DVD works. Can I purchase an external cd drive that will work with my iMac?

Welcome to the Apple Support Communities
Any external optical drive will work with your Mac. If you want an Apple USB SuperDrive, see > http://www.tuaw.com/2012/04/02/use-the-macbook-air-superdrive-with-any-almost-ma c/
The best option is to take the Mac to an Apple Store and get the Mac's SuperDrive repaired

How do I clean my mid 2007 iMac? The disk space is running VERY low and I would love an idea. I make videos and upload them to youtube and I need space to do that. Thanks for your time!

If you have an idea please respond!

You should never, EVER let a conputer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your iMac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Look though other Apple Mail folders like the junk mail and delete the mail that is in there. Look through your sent items folders and see there is any mail in there that can be deieted.
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Other things you can do to gain space.
Once you have around 15 GBs regained, do a search, download and install OmniDisk Sweeper.
This app will help you locate files that you can move/archive and/or delete from your system.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck!

Connecting mid-2007 iMac to LG TV via mini dvi to HDMI

I am trying to connect my mid-2007 iMac to my 42" LG HDTV to no avail. I am running iOS 10.6 Snow Leopard. I bought the mini dvi to HDMI adapter and plugged the iMac into the TV. I went to the display tab in the system settings and see that the iMac recognizes the tv. I went to the arrangements section and it recognizes the tv. When I click on gather windows it even calls it the LG TV. However, there is nothing showing on my TV. It says no input detected. When I move my mouse to the right side of the screen it disappears like it is going to a second monitor.
Any thoughts?

Hey Corinthone, did you ever figure it out? I have a mid2007 iMac running snow leopard & a 120hz LGTV 42". I was having the same issues as you(yes Frankie, I made sure I was selecting the correct hdmi input). Now with the same setup, my LG recognizes the HDMI input from my iMac. It says connecting but then 'no signal' on the screen. The hdmi2 is still showing a connection in 'inputs' just no picture on TV. I started changed the setting via my mac but still nada. The lg is 120hz. Does that have anything to do with it? Thanks

My mid 2007 iMac doesn't recognise 2GB RAM module in DIMM/1

I am trying to upgrade the RAM in my mid 2007 iMac from 1GB to 4GB. It originally had a 1GB module in slot DIMM/0 and nothing in slot DIMM/1. I inserted the two new 2GB modules, one in each slot but DIMM/1 just reports as being 'empty'. I have tried swapping the modules and different configurations of 1 & 2GB modules but DIMM/1 only reads the original 1GB module (from DIMM/0) and reports 'empty' when either of the two 2GB modules are installed.
I have reset PRAM, checked EFI firmware update and updated OSX to version 10.6.8 (from 10.5.8) but still the same result. The best I can get is 3GB (2GB in DIMM/0 and 1GB in DIMM/1). I am definitely pushing the modules firmly into place. Is there anything else I can try?

Your machine will accept up to 6GB of RAM however you must a) have the correct specifications, no variations at all and b) must push hard with both thumbs to fully seat the RAM. The correct RAM for your system would be the specifications shown here. I suspect 1 of three things with the RAM you bought.
1. Wrong specifications!
2. Incorrectly installed
3. Defective RAM
I would STRONGLY recommend using Crucial or my preferences OWC, which is the memory shown in the link.
BTW I have a late 2007 24" 2.8GHz iMac with 6GB of RAM.

Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion/Mavericks' Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Get an external hard drive on which to store some of your files after which you can
      erase the data from your internal drive to free up space.
5. Also see Freeing space on your Mac OS X startup disk.
6. See Where did my Disk Space go?.
7. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.

I want to dual boot Windows 8 on my 20-inch, Mid 2007 iMac, from an external USB drive.

I want to dual boot Windows 8 on my 20-inch, Mid 2007 iMac, from an external USB drive. The internal drive is completely dead, it doesn't even show up in Disk Utility. I'm running 10.8.2 from the external drive. When I start Boot Camp Assistant, at the Introduction page, when I press the continue button nothing happens. Do I have to have internal drive to run Boot Camp Assistant? Can anyone provide me with the steps to dual boot, with his setup? Thanks in advance!

Hi maczimillon,
Only follow these steps, it works for my:
Open "System Information" and note your "Boot ROM Version" (some like MBP51.007E.B06)
Navigate to "Utilities" in Finder and open the package contents of -BootCampAssistant.app- with right click. Duplicate the "Info.plist" file to the Desktop e.g. and open that with Text Editor.
You must locate the keys "DARequiredROMVersions"and "USBBootSupportedModels"
Add new strings with the information of your machine under booth keys (step 1), always respect the format, such as: <string>MBP51.007E.B06</string> for the frist key and <string>MBP51</string> for the second key.
Save changes and replace the original plist file (it may ask you to enter admin pass)
If you proceeded correctly you will see the checkbox "Create a Windows 7 USB install disk" enabled in Boot Camp Assistant.
Then you can follow the usual Boot Camp installation using your WIN8 DVD iso image . The assistant program will proceed resizing your disk partition and installing necessary drivers for your iMac.
I strongly recomends you to use thirld party's bootloaders like rEFInd (rEFIt) because of the Apple SMC versions of some old machines should not be able to boot properly from external devices like USB drives.

I have a 24-inch Mid 2007 iMac. Should I upgrade to Yosemite?

I have a 24-inch Mid 2007 iMac. Should I upgrade to Yosemite? I was advised by genius bar that it would slow down my iMac.

According to sources such as http://mactracker.ca download database specs for
the iMac (24-inch Mid 2007) your computer can use more RAM than it has now.
Maximum Memory: 6.0 GB (Actual) 4.0 GB (Apple)
Memory Slots: 2 - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMM
•iMac: How to remove or install memory
And so it should work better even if you stay with Mountain Lion OS X 10.8.5.
The hardware upgrade will help the Mac OS + applications, in basic functions.
[This computer is already considered 'vintage' by Apple...]
Depending on the amount of use the computer has seen so far, it may also be
a candidate for a replacement hard disk drive; perhaps a larger capacity, too.
If you consider an upgrade, also consider a complete backup and a bootable
clone of the current (if updated to 10.8.5 with its applications updated) OS X
on an externally enclosed hard disk drive with its own power supply. You can
see a few of these that do not run on Mac port power, & standalone, at OWC.
{The company known as OWC is macsales.com, a fair example of mac-centric
supplier of quality products for Mac community, awhile. Or so people tell me.}
Clone utilities such as superduper, carboncopy cloner, or disk utility can work.
Test a cloned OS X copy for boot-ability and other function before moving on.
Could be you'd be better off with this computer on Mt Lion than a later OS X.
And a newer later computer should also have hardware specs and some up-
ward expandability for use with the expected new & future changes to OS X.
Hopefully you can get some fair use and more years from your iMac 24".
And that means hope for the best, and plan for the worst. Backup, backup...
Good luck & happy computing!

Can I use faster memory in Mid-2007 iMac?

I currently have factory spec (1 GB) memory in my 20" (Mid-2007) iMac. Specs for memory in this machine say I need pc2-5300, unbuffered, non-parity, 200-pin, 667MHz DDR2 SDRAM. I noticed my hardware has an 800 Mhz bus.
1) Can I use 800 Mhz RAM that is otherwise the same spec?
2) How important is CAS Latency (e.g., the installed memory is spec'd as CL=5, the 800 Mhz RAM all seems to be CL=6)?
Any help is greatly appreciated!

I totally agree with lenn5! Many folks here in the forum have reported all sorts of problems, everything from kernal panics to won't even boot when they installed the 800MHz ram. You will see a great improvement in performance by adding another 1GB or 2GB module in the empty slot, or max it out with a 2x2GB kit.

Mid-2007 iMac Running Mavericks Windows 7 Home Premium 64-bit Install

How do I go about installing a Windows 7 Home Premium 64-Bit (OEM) partition on a mid-2007 iMac running Mavericks?
Apple says that 64-bit Windows 7 isn't supported by my model iMac, but I know for a fact that other people have gotten it to work. I'm just a little unclear on how exactly to do it. In any case, I made the mistake of buying two copies of Windows 7 64-bit under the assumption that they would install just fine on my iMac and MacBook Pro (MacBook Pro is from 2007 as well), so I need to get this working.
What version of Boot Camp should I use? What version support drivers should I download? Apple says that Boot Camp 5.1, which is what I have, is incompatible with my iMac, and it says the same thing for every driver download that supports 64-bit versions of Windows 7, but would it be correct to say that this "incompatibility" is only the case if I don't first modify my Windows 7 installation disc according to the instructions in the attached link?
There is a Windows XP partition on my MacBook Pro, so I figure I can get on it to modify the installation disc before attempting a 64-bit Windows 7 install on the iMac.

Will Airplay via Mountain Lion work on 2 GHz Intel Core 2 Duo (mid 2007) iMac

One of the main reasons I would purchase OS X Moutain Lion is for its AirPlay feature, in particular to stream Hulu from my iMac to my Apple TV 2. In reading some of the preliminary reviews of Moutain Lion, AirPlay is not supported on older MacBook Pro's. Will it work on my mid 2007 iMac (model identifier: iMac7,1) running a 2 GHz Intel Core 2 Duo with 4 GB 667 MHz DDR2 SDRAM?
I'm currently running Mac OS X Lion 10.7.4 (11E53).
Any help is appreciated. Thanks!

AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer).
