Try connecting the exFAT drive back to the Windows notebook and use the "Safely Remove Hardware" icon in your Taskbar.
Run a updated malware scan and/or remove any original data and reformat the drive again.
Your issue doesn't appear to be widespread, so I'm leaning towards something that got messed up somehow.
Mac's can read/write MBR/GUID and FAT32/exFAT drives, only can read NTFS, so it shouldn't be having a problem.

Problem not able to start my MacBook Pro 15"

Recently i have updated my Mac OSX Leopard to Mac OSX Snow Leopard.Also i have changed the battery and i have format the hard drive completely when i install Mac OSX Snow Leopard.

That is a kernel panic. Visit The XLab FAQs and read the FAQ on how to diagnose kernel panics.
Without seeing the panic log it's difficult or impossible to know what is causing it. In some cases it may just be a software glitch. Restarting the compute may be all you need do. But if it appears every time you try to start up, then there's a serious problem with the OS X system installation or there is a hardware problem. To help narrow down the problem boot from your OS X installer DVD. If you can do that without a panic then it's most likely not a hardware problem. In this case try the following:
Repairing the Hard Drive and Permissions
Boot from your OS X 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 Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) 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. Now restart normally.
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.
If this doesn't resolve the problem then download a utility such as TinkerTool System or Snow Leopard Cache Cleaner - VersionTracker or MacUpdate - and use it to clear user, system, and font caches as well as old log files. See if this fixes the problem. If not then I would erase the drive and reinstall OS X.
Some other things you can do that may help:

You are experiencing a Kernel Panic, as shown in Apple doc. #HT1392.
Bad or incompatible RAM is, more often then not, the cause of most Kernel Panics. It could also just need to be reset.
Here's the most used site for Resolving Kernel Panics. Please do all the steps in order, even if you don't think you need to do a certain step.

I am not sure what year my Macbook Pro is but it has System Version: Mac OS X 10.6.8 (10K549), will I be able to download Mountain Lion or will I need to upgrade first?

I need to totally format my macbook pro 13" mid 2009, can i use my friend's macbook pro 13's dvds?

my macbook pro 13 is originally shipped with mac os x 10.5.7, now with 10.6.8, but i dont have the dvds with me, i also dont want any of the information on it, can i use my friend's macbook pro 13's dvds? what can i do?
My macbook pro 13" dvds have these on them
    DVD 1: 13 inch macbook pro mac os x install dvd version 10.5.7 2Z691-6468-A Disc version 1.1
    DVD 2: 13 inch macbook pro applications install dvd disc AHT version 3A174 disc version 1.0   2Z691-6458-A
My friend's macbook pro 13
    DVD 1: 13 INCH MACBOOK PRO MAC OS X INSTALL DVD Mac os x version 10.6.7 Disk version 1.2
    DVD 2: 12 in macbook pro applications install dvd AHT version 3A21 Disc version 1.1
Would my friend's dvds work to format my macbook pro to factory settings as if out of the box?
i also had windows running on my mac, i used disc utility to erase the partition for windows, not bootcamp, so the partition is empty, i cant get the main hard drive extended as it was before because it gives me a message saying "could not modify partition map because filesystem verification failed", and when i try to verify it through disc utility it says that i need to my os x dvd and repair it, if i just format it, will that all go away?
thank you

Simple answer is no.
Slightly more complicated answer;
You may be able to boot from the disc and use Disk Utility to partition and wipe the HDD (though it may not boot at all).
You can't install an OS from the other computer's discs. It simply will not allow the installation.
You would also be violating the software licence agreement.
As your originals are 10.5.x, you can buy the Snow Leopard retail installer (10.6.3) and format and install from that.

Can't format my macbook pro using the instructions on here or google or youtube. Please Help!!

I'm trying to format my macbook pro using OS X 10.5.8. I've tried all the instructions that I could find, but still no luck.
Instructions examples:
1) Go into disk utility and erase the hard drive.
Problem: when I do that, it doesn't let me because the erase button is in the "greyed", so I can't click on that.
2) Restart the computer and hold down "c" and follow the instrctions...
Problem: I did that, but it just restart normally, it doesn't take me to some special screen.
3) Restart with the Mac OS CD installer and hold down "c" as it reboots.
Problem: same as number 2.
4) Restart and hold down "option" - disk utility - erase HD
Problem: I did that, and the hard drive icon with the arrow pointing up pops up; however, when I click on it, it just boot up as usual, and when I go into disk utility, I had the same problem as number 1.
This is really frustrating!! Please help!!
Thanks all!

That only works for other drives/partitions, you can't format or erase the boot drive/volume/partition obviously.
2) Restart the computer and hold down "c" and follow the instrctions...

No disk inserted, you need a bootable disk to use the c key at boot.
3) Restart with the Mac OS CD installer and hold down "c" as it reboots.
Problem: same as number 2.
Perhaps you held it too late.
4) Restart and hold down "option" - disk utility - erase HD
Problem: I did that, and the hard drive icon with the arrow pointing up pops up; however, when I click on it, it just boot up as usual, and when I go into disk utility, I had the same problem as number 1.
The option key held at boot gives you Startup Manager, which gives you a choice of bootable options provided the boot cd is inserted obviously.
If you didn't wait for the cd boot option to appear and clicked the hard drive and arrow right away, it's possible you missed the cd boot option as it takes a bit longer to appear on the screen.
If you went all over the above and can't boot from the 10.5 cd, then what likely occured is your operating system was upgraded to a later OS X version like 10.6 or later and the firmware has been updated to ignore booting or recognizing that 10.5 boot disk as that operating system is now obsolete.
Another option is your using the wrong 10.5 disk, like it's from another model of Mac with different hardware drivers, thus can't be used on your machine.
Sometimes the disk is a retail copy, but is only for compatible Mac's that came PRIOR to the release of the retail disk, obviously not for Mac's that came afterwards because of new hardware drivers not on the burned disk.
If your machine is on 10.4, it might not have enough RAM for 10.5.
If your machine is on 10.5 now, then you should be able to boot from the disk that came with the machine, unless it's defective, scratched or dirty.
If your Mac is a Intel processor Mac, then you should be using 10.6 at least now, it's still getting updates to 10.6.8 (not for Safari or Java 6, but you can disable both and use Firefox)
Usually a 10.5 issued Mac is too old for the later OS X versions of 10.7 and later, perhaps the MacPro tower being the rare exceptions.
OS X 10.4/10.5 need to upgrade, 10.6.8 ok still
Also usually a 10.5 era issued Mac is beyond it's end of life stage, likely to die soon and not worth spending great sums of money to upgrade RAM and all software for 10.7 and beyond, your better off buying a new machine for 10.7+ or use it on 10.6.8 max until it drops dead or sell it online.
You didn't state your Mac's model identifier, it can be gleamed from System Profiler or Apple menu > About this Mac > More information.
With the model identifier, current operating system version running and the RAM amount installed, we can look up the machine on our database and recommend a course of action or if you cannot install 10.5 on that machine.

Is there any way to sync notes from iPhone 4 to MacBook Pro?

Is there any way to sync notes from iPhone 4 to MacBook Pro?

If the phone doesn't power on and isn't seen by the computer then you wouldn't be able to pull data off it with the USB connection to your computer.
You could pursue data recovery if the notes are very valuable, but the cost can be similar to having data recovered from a failed computer drive(possibly prohibitively expensive).

Imessage and facetime not letting me sign in macbook pro

I have a mac mini, an iphone and a MacBook pro. I have no problems using imessage and facetime in two of my devices. MacBook Pro is not letting me sign in. Facetime is sending me a message to check my network and I don't have any problem with that and imessage is doing nothing. I write my Apple ID password and it start acting like it is gonna work but nothing happen. In my phone I am trying to set availability to the Text Message Forwarding but is asking me for a code I don't have and is not sending it to the MacBook Pro either. Thanks for helping me!

This could be a complicated problem to solve, as there are many possible causes for it. Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
Before proceeding, test on another network, if possible. That could be a public Wi-Fi hotspot, if your computer is portable, or a cellular network if you have a mobile device that can share its Internet connection. If you find that iMessage works on the other network, the problem is in your network or at your ISP, not in your computer.
Step 1
Check the status of the service. If the service is down, wait tor it to come back up. There may be a localized outage, even if the status indicator is green.
Step 2
Sign out of iMessage and FaceTime on all your Apple devices. Log out and log back in. Try again to sign in.
Step 3
Restart your router and your broadband device, if they're separate. You may have to skip this step if you don't control those devices.
Step 4
From the menu bar, select
           ▹ About This Mac
Below the "OS X" legend in the window that opens, the OS version appears. Click the version line twice to display the serial number. If the number is missing or invalid according to this web form, take the machine to an Apple Store or other authorized service center to have the problem corrected.
Step 5
Take the steps suggested in this support article. If you don't understand some of the steps or can't carry them out, ask for guidance.
Step 6
From the menu bar, select
           ▹ System Preferences... ▹ Network
If the preference pane is locked, click the lock icon in the lower left corner and enter your password to unlock it. Then click the Advanced button and select the Proxies tab. If the box marked SOCKS Proxy is checked, uncheck it. You don’t need to change any other settings in the window. Click OK and then Apply. Test.
The result may be that you can't connect to the Internet at all. Revert the change if that happens, or if iMessage still doesn't work. Remember that you must Apply any changes you make in the preference pane before they take effect.
Step 7
Select from the menu bar
           ▹ System Preferences… ▹ Flash Player ▹ Storage
and click
          Block all sites from storing information on this computer
Close the preference pane.
Step 8
Make sure you know the ID and password you use with iMessage. Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Use the search box in the toolbar of the Keychain Access window to find and delete all items with "iMessage" or "com.apple.idms" in the name. Log out and log back in.
Step 9
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
If iMessage worked in the guest account, stop here and post your results.
Step 10
Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you start up, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start and run than normal, with limited graphics performance, and some things won’t work at all, including sound outputand Wi-Fi on certain models. The next normal startup may also be somewhat slow.
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.
Test while in safe mode. After testing, restart as usual (i.e., not in safe mode) and test again.
If iMessage worked in safe mode, but still doesn't work when you restart in "normal" mode, stop here and post your results.
Step 11
Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/com.apple.apsd.plist
Right-click or control-click the highlighted line and select
          Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
Step 12
Reset the NVRAM.
Step 13
Reset the System Management Controller (SMC).
Step 14
Reinstall OS X.
Step 15
If none of the above steps resolves the issue, make a "Genius" appointment at an Apple Store, or contact Apple Support. When you set up a support call, select "Apple ID" as the product you need help with, not the hardware model. That way, if you're not under AppleCare, you may be able to talk your way out of being charged for the call.

Photos taken on My I Phone 6 do not show up ON my Macbook Pro both on I cloud

I have my I phone 6 with IOS 8.3. Then I have my Macbook Pro w/Retina Display 2014 with 10.10.3 with Photos. I migrated my I Photo Library to Photos and that went well. However since I updated both my I Phone and Macbook pro, Pictures I take on my I Phone 6 do not show automatically up in Photos on my Macbook Pro. Both my I Phone 6 and Macbook pro are signed into I cloud for photos. The pictures I take on my I Phone 6 show up in the Icloud photos but not in Photos on my Macbook Pro. Am I wrong to assume that when I take photos on my I Phone 6 they will show up on my Macbook pro in Photos? Do I still need to hardwire to the Macbook and import my photos off my I phone? Is there a setting I have not turned on, I have looked I do not think I have missed a setting anywhere? Is there a problem with IOS 8.3 or OS X 10.01.3? Just wondering what is up. Anyone else having this issue?

The music being available for redownload has only been possible for a few months. Before this you could not redownload. The owners of the rights to the ringtones do not allow itunes to provide this feature. hopefully they will at some point.
Regardless, you should always maintain a backup.
Sorry.
You can try contacting itunes support and asking for an exception.
