Since it's only 4GB you can't put larger than 4GB sized files on it, so there is no need to format it exFAT on a PC or OS X Extended Journaled on a Mac for larger than 4GB sized files. Just use it like it is FAT32/MSDOS and if it's NTFS, then use Disk Utility to format it: Partition 1, Option: MBR, Format: MSDOS. I too had the same problem. On a PC, you simply right click and select 'format.' The reason I wanted to do this on the mac is because I have an 8gb usb flash drive that for some strange reason, when I deleted all the files it still showed only 1.5 gb available making it impossible to put any more than 1.5 gigs of new data on it.
I went to utilities like the previous posters said and simply clicked 'erase.' No need to partition, don't understand why you would need to do all of that to do a simple format. I too, got the 'couldn't unmount disk' message so I went to the drive on the left, right clicked and clicked 'unmount disk' then went ahead and erased it. Now it's good as new. This is the first convoluted thing on mac that I have come across as compared to windows. I have been a mac user for 2 years now and swear by them but this is probably one of the dumbest things I have seen yet. At least now I know how to erase.
Way too complicated but everything else on a mac is way better than windows. I hope this helps. Apple Footer.

Hi there, just yesterday I bought a used MacBook Pro 2007 and it came with Mac OS X Lion. Unfortunately I erase the disk with the system and now when I try to download a new copy of lion through Mac OS X Utilities I always get “Item temporarily unavailable” (I tried different apple accounts, one of then with lion in history purchase, I tried to correct the date on terminal and even did an reset nvram). My next step was Internet Recovery Mod, but once again no results, option+command+r didn’t work.
Already getting crazy I was hopping to make an bootable usb disk and install from there. I started by preparing my usb 3.0 disk with diskapart command in windows terminal and fallow all the steps in TransMac with different mac os versions but the final result was always the same, when I plug the usb pen in my mac, I turn on pressing option key and I select usb but it always go to Mac OS X Utilities. Any ideas what to do now? Please someone help! Hi there, just yesterday I bought a used MacBook Pro 2007 and it came with Mac OS X Lion.
