Mac will not unmount or partition

So I just got my new SSD in today because apparently my old one was a dud. The SSD won't partition or unmount. I go into disk utility on my USB and on my internet recovery. I have the right format and partition table selected. The disk utility takes 20 minutes to try to unmount the disk then it errors and says partition failed and couldn't unmount disk.

NJBloom,
perhaps your internal SATA cable needs to be replaced rather than your SSD? If you have an external drive enclosure, or a SATA-to-USB or SATA-to-FireWire adapter, you can try partitioning your SSD externally. If that goes smoothly, but is problematic internally, then that would point to your internal SATA cable as the culprit.

My mac will not open this specific website.

Ok so I enjoy playing this game called rigs of rods. Very entertaining. Anyway all of a sudden my mac will not open this website no matter what I do. Every time it just times out and says can't connect to server. I know it isn't the website because I can access it on my phone over 4g and over the same wifi network that my mac is on. I have reset safari and logged into the guest account and it still wont work. The only way I have gotten the site to work was by using a IP blocker or booting into safe mode and using safari. I have tried to use 3 different browsers and none will work. I'm almost for sure it has to do with my network settings but I cant figure it out. Help would be greatly appreciated as this is getting very frustrating.

Since you're running Lion, just try a new system install - it won't affect your data or apps, but you should, anyway, have a backup regardless.
Boot to your Recovery partition by holding down the Command and R keys whilst booting. At the Recovery window, first repair permissions again, then verify and, if necessary, repair your hard drive. Then quite Disk Utility and elect to reinstall the OS anew - it will only overwrite system files and the like, not touching your data, apps, etc. It may take awhile to complete.
After completion, reboot and see if the problem still exists. If it does, I'm just at a loss...

My WD 2tb external hard drive will not unmount from my MacBook Pro.

My WD 2tb external hard drive will not unmount from my MacBook Pro. It no longer even shows up in finder, however it does show up in Disk Utility. I have tired so many of the suggestions on the internet all to a fail.
I keep getting the message to be sure that all applications are closed before ejecting the drive. I have no clue how to tell which appliactions are using the external drive to shut them off. I turned off Time Machiene to be safe.
I don't need anything on the external drive, I am just trying to erase it, save my current info, and migrate it to my new MacBook Pro.
I have been about four days now with this issue all over the internet, in this community, and watching videos on everything and nothing about this topic to a fail.
I think I am doomed and have lossed this external drive because of some wierd application that will NEVER close on my hard drive for it to disconnect correctly. It's annoying.
Does anyone have a solution?

Have you trie using another USB port? Can you test the USB ports with other USB devices to assure they are working? You may want to reinstall OS X in case there has been a driver glitch.
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
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. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

External Time Machine Disk Will Not Unmount

This past weekend I did clean installs of Lion on new SSD drives in my MacBook and MacPro. The MacBook backs up to a Time Capsule with Time Machine and is working perfectly. The MacPro backs up fine and says the backup is completed but it will not unmount the external Time Machine disk I use for the backup after completion. This was not a problem using the same setup with Snow Leopard. I looked at the Console which says Backup completed successfully. Any idea what is going on with this? Thanks in advance.

Wait a minute . . . I missed that before.
Is that disk connected directly to the Mac? If so, no, Time Machine doesn't unmount directly-connected drives after a backup, only sparse bundles on network drives.

Mac will not boot up, white screen with turning gear for hours on end

mac will not boot up, white screen with turning gear for hours on end

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. The easiest way to deal with the problem is to boot from an external drive, or else to use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 9
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 10
Repeat Step 9, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 11
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 12
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

The Mouse moves but will not click. Already tried restarting and the pram zap. The problem starts when I log out of my main profile.

Should I just delete the new profile and try again?

If the modem is also a router, either use the modem in bridge and run pppoe client on the TC.. that is assuming ADSL or similar eg vdsl. If it is cable service.. and the modem is a router, then bridge the TC.. go to internet page and select connect by ethernet and below that set connection sharing to bridge.
Please tell us more about the modem if the above gives you issues.

My mac will not show images when on the internet? I think I have inadvertently changed some settings but nor sure which one.

I am going to assume you are using Safari here. If so then go to the Apple menu bar and hit Safari-> Preferences. Under the Apperance tab there is a check box that is called "Display images when the page opens". Check if that is unticked.

Also, pop up blocker works for some time and then just stops working. I have to close and restart Firefox to get it to work again. Help!

I had the same problem, but with Firefox 4.0. My first thought was to update Firefox (after of course restarting FF), but that didn't help it and I had the same problem.
Among others, I had an extension installed and enabled called Tile Tabs 4.10 that I thought could feasibly creating this problem. So I went into my add-ons manager and disabled it, restarted Firefox and the tabs worked properly again. Unfortunately, the Tile Tabs extension is my favorite Firefox add-on and I use it almost every day for managing my web work tasks. I went to the add-on page for Tile Tabs and saw that there was a notice that version 4.10 didn't work properly on Mac OS, and to install version 4.9 of the extension. I saw they had a new, not-yet-reviewed version 4.11 that addressed the Mac OS problem, installed it, and everything seems to be working properly.
I have no idea why all of a sudden I had this problem, as I hadn't updated Firefox or the Tile Tabs extension recently. Also, obviously this might not address your problem, especially if you don't have that add-on installed and enabled. But our problem started at the same time for both of us it appears based on your post time, so its probably not coincidence.
But its worth a look, and you might want to check out other extensions if you don't have Tile Tabs that could be causing the problem.

So now that you have repeated the same thing three times that doesn't make things any clearer at all.
You are copying files from where to where?
How are you attempting to copy files, software or click and drag?
Any other detail would be helpful.
