Could Not Validate Source Error 254 Iso To Usb

Restore Failure Could Not Validate Source Error 254
encountered the frustrating and almost Windows-like cryptic error message “Could not validate source – Invalid argument” error. Looking in the system log via theConsole app I suspect this is because internallyDiskUtil tries could not validate source - error 254 mac to run /usr/sbin/asr to verify the image, which fails. $ asr imagescan --source ubuntu-rescue-remix-12-04.iso only UDIF and NDIF images can be scanned. asr: image scan failed - Invalid argument. 123 $ asr imagescan --source ubuntu-rescue-remix-12-04.isoonly UDIF and NDIF images can be scanned.asr: image scan failed - Invalid argument. UDIFandNDIF are image formats used by Apple, and Disk Utility is pretty hopeless with anything could not validate source - invalid argument that falls outside of these standards. The iso standard is short forISO9660 and is a standard that defines the format of an image intended for burning to CD. Even after usinghdutil to convert the image to UDRO (a UDIF Read-Only image) Disk Utility will still stubbornly refuse to help. Disk Destroyer Duplicator to the rescue Being Unix based, OSX has the command linedd utility available. Short for Disk Duplicator, dd is a block level reader/writer that makes raw copies from one file to another. But you want to copy the image to a device, right? That’s fine, because everything in the world of Unix/Linux is a file – even devices. Informally referred to as Disk Destroyer, should you tell dd to output to the wrong device then your day is definitely going to be spoiled, so to avoid any mishaps we will make sure we know which devices on your system is your USB stick. You can determine this from the command line: Shell $ ls -la /dev/disk* brw-r----- 1 root operator 1, 0 9 Feb 07:49 /dev/disk0 brw-r----- 1 root operator 1, 2 9 Feb 07:4

2007). Apple Disk Utility comes back with user unfriendly errors citing an ‘invalid argument'. It insists on doing some silly ‘image http://www.onpaws.com/2009/10/fixing-disk-utility-image-restore/ scan' which never actually works, thereby blocking any successful image restore. Delving deeper I thought it was likely some other component utilized by Disk Utility was failing and I found what it was. It turns out that Disk Utility employs Apple's ASR utility, stored at /usr/sbin/asr To learn more you can run ‘asr' by itself in Terminal. While man asr shows could not a lot more, I'll save you from reading that (this man page has even got a History section).
