When the flash memoryUSB hard drive device appears to malfunction it maybe possible to restoreit by reformatting it using a computer with Windows OS. Insert the flash or USB hard drive into the USB port then Click on Control Panel - AdministrativeTools - Computer Management - Disk Management. Then right click on Disk 1removable drive and click Format. After the flash drive has been formatted itwill indicate that it is Healthy. You need to format the flash or external drive. Format thedrive as primary drive and in FAT32. (FAT32 will allow data to be exchangedbetween MACs and PCs also between XP/Vista and earlier versions of Windows).

The drive will need to be reformatted to the HFS file spec for Mac. You will lose any data on the drive when you do that.

However, you shouldn't need to do anything other than plug the drive into your iMac, then once the icon appears on your desktop (may take a minute), double-click on it to start the Mac install process.

If the Mac install process fails for some reason, it may be because the drive was previously installed on a Windows machine, and you may have to simply treat it as a "raw" new drive, and reformat it using the Mac operating system utilities.

Hope that's helpful.

You have to reformat your memory card.

as the mac has a diffreent format to a pc you cannot connect up the drive to a pc because it simply wont recodnise it. the best way is to network the 2 computers together then alow file sharing on the mac and searcc with windows through the network to find the drive. then copy them across the network to your pc. this will then reformat the files to PC files at they hit your PC

move the auto install file then reformat the flash drive as fat.

Inside the iMac or as an external drive? If internal: Use the OSX Installation disk
