If you follow the instructions above then Windows will, by default, format your disk using Microsoft’s NTFS filesystem, while a Mac might suggest the Mac OS Extended filesystem.Start with a clean USB flash drive and install it in your computer’s USB port. Preparing a USB drive to install Ubuntu is a lot more complicated, but if you want. Formatting Usb Drive For Mac And Pc Access.Start your Journey into Free and Open Source Software Nathan Haines.You may also be preparing the drive for use as, say, a storage device for a media player or to record TV programmes on a TV with a USB port.eraser disk wipe, erase-disk Overwrite the flash (boot device) with. There are free drivers available, but again these are limited to read-only access.The main reason for formatting a USB drive as Fat32 on a Mac is that you want to be able to use the drive on a Windows PC, as well as a Mac perhaps to transfer files between the two machines. However, neither is suitable if you want to move files back and forth between Macs and PCs: OS X can read NTFS volumes, but it can’t write to them, while Windows in its default configuration can’t access HFS+ disks at all.
Format Usb Drive For Windows Full Read AndThis is supported by all versions of Windows and OS X (as well as Linux), but it has the drawback of not supporting individual files larger than 4GB – which can be a pain if you work with large video files or databases.On a Mac, you can format any disk as FAT32 by simply choosing “MS-DOS (FAT)” from the dropdown menu in Disk Utility before you click Erase…. In most cases we recommend you select Microsoft’s exFAT format: this will give you full read and write access in both Windows (Vista or later) and OS X (Snow Leopard 10.6.5 or later).If you need compatibility with systems that are older than this, you’ll need to fall back to the ancient FAT32 format. You can choose this from the drop-down menu in Windows’ Format dialogue, or in the Erase pane of Disk Utility.Splitting up a file into more chunks gives the drive controller more work to do, and makes it more likely that the data will end up fragmented into lots of blocks scattered about your disk, making it slower to access.With a modern flash drive, it’s unlikely you’ll notice much difference either way, so it’s up to you whether you stick to the 4KB standard or pick a smaller allocation unit size. However, this can have a negative impact on performance, especially if you’re using a mechanical disk drive. In practice though, most of the files on your USB drive will probably be many megabytes in size, so the impact of wasting a few kilobytes here and there is negligible.If you plan to save lots of small files to your disk then reducing the allocation unit size might be a good idea. A file that’s only 1KB in size will still occupy 4KB of space, while a 5KB file will take up 8KB, and so on. Simply put, this determines the size of the chunks in which storage is allocated for your files: if you choose 4096 bytes (the NTFS default), every file that’s saved to that disk will be allocated space in multiples of 4KB.Slicing up disk space in this way isn’t perfectly efficient. How to format a USB drive: allocation unit sizeAs well as choosing a disk format, Windows also invites you to specify an “Allocation unit size”.
