For instance, if you DD copy a 4GB image onto a 16GB USB, then even if you can access your drive from Windows, you will only ever be able to access 4GB of your drive, and not 16.įinally, the choice between DD and ISO only applies to ISOHybrid images (not all ISOs are ISOHybrid!), which is a somewhat brittle hack that tries to make optical disc filesystems (ISO9660 or UDF) something that they were never designed to do (which essentially boils down to making it look like a completely different file system, along with constructs, such as a partition table, that are not meant to apply to optical media), so it takes A LOT of trial and error to get something that kind of works, but has some limits. Also, even if you are able to access the content, you will find that the available size you have is a lot less than the total size of your USB. So if you want to modify some settings, or want to access the doc, or, say, copy the firmware for your Wifi card onto the USB, you may not be able to do so. But this can also be one of the drawbacks, as it means you will usually find that you cannot access the content of your USB any longer after it has been created. One advantage is that it doesn't require partitioning or formatting, and it can create USB drives with file systems that Windows is unable to handle on its own (such as ext# or anything *BSD). That's all DD does, and it usually ensures that you get an exact clone of the image or device the maintainer of the distro created. onto the USB, starting at the first byte of the first sector, and continue to copy bytes until the data from the image is exhausted. then what Rufus or any other DD application will do is copy 33 ED 90 90. Basically, this flat copies the image byte by byte onto the USB, so if you look at the image in hex and see it starts with something like 33 ED 90 90.
I confirmed, by performing an internet search, that these values match the ones from the official image.įor an Arch Linux ISO, could you please explain the overall difference, when creating a USB Flash Drive, between Rufus' ISO Image mode and it's DD Image (disk image) mode? I am trying to understand what steps Rufus goes through, depending on which mode is selected, and how that affects the outcome.ĭD is an exact clone of the image onto the USB. If using an ISO image, I clicked on the # button (at the bottom of the Rufus interface), to compute the MD5, SHA1 and SHA256 checksums, which are therefore present in the log I copied.I also tried one or more of the following:.I ran a bad blocks check, by clicking the "bad blocks" check box in Rufus, and confirmed that my USB is not defective.
