ISOUSB request

Post#1 by Blaze » 31 Mar 2017, 20:28

Suggestion to add isousb-1.5.xzm (mirror) in Porteus.
A graphical tool to copy a hybrid ISO onto a USB key.
Image
I found this tool here https://aur.archlinux.org/packages/isousb/ and added Russian localization to isousb-1.5.xzm.

But one thing that I don't like and it must be fixed - after use this tool, the file system of usb convert to isofs and I can't to copy, execute, remove, etc in this usb stick with isofs.

Probably, master of bash Bogomips or someone else can fix it (If it's possible) :)

So basically it makes the USB drive a CD!! The files are there and can't be changed. Not necessarily a bad thing. Is the USB drive bootable?

Yes, this tool is format all current data on your USB flash drive and convert USB2CD.

Is this the same app?? http://www.isotousb.com/ Cause it says it is bootable on Windows systems.

We're missing something. A driver maybe? The author certainly wouldn't create an app that creates non-accessible USB drives.

This tool copies raw data from dvd/cd to usb, low level copy using dd, so the filesystem gets copied too and thus you have a complete clone of data including ISO filesystem.
I find this tool pretty unuseful unless you really want to convert a usb in a CD/DVD due to lack of DVD discs and abundance of USB pens.

I really don't know what you want when saying this would be a great tool if usb wouldn't get converted to ISO fs, what you are saying is this tool would be great if it wouldn't work ;-)

If what you want is to get a bootable & writeable usb with all data from DVD that looks like a DVD and also like a usb conventional fs (ext?, vfat...) then you will need to convert it to hybrid ISO, usually this will require original ISO to be built in a special way but you can use tools to patch it (isohybrid, etc)

if what you want is simply put all dvd data in usb pen, it would be better to actually mount iso file and copy all data to usb partition.

hmmm... An interesting point. You have no more discs, or you have a bunch of discs and a new pc which doesn't have a CD/DVD drive so you want to backup the discs to USB drives. Either situation seems reasonable. But with the discs all on USB drives what do you do with the USB drives if they can't be read??? We're missing a piece.

if your main interest is just backup CD/DVD discs the better way is to make it iso files and save them all into usb drive, the only drawback is if you want to boot from them, i.e. if you have a LiveCD you want to backup while still being useful, in this case use hybrid ISO

what do you mean with usb drives that can't be read? you can always read usb drives even those created with this curious tool

I boot standard ISO files all the time with Grub4DOS (non-UEFI) and Grub2Win (UEFI). Windows Recovery, BArtPE, Porteus, etc.

I boot standard ISO files all the time with Grub4DOS (non-UEFI) and Grub2Win (UEFI). Windows Recovery, BArtPE, Porteus, etc.

All those iso images are OS images and yes they are bootable but they are not an ISO 9660 fs but an extension probably "El Torito" extension just to make it bootable, I was talking about ISO 9660 filesystem and booting from usb drive, the only way to boot from USB drive making it also read write is hybrid ISO, maybe you can also get a bootable usb driver if your source is a bootable iso image (such as El Torito extension) without proper patching but not by default in any ISO 9660 and also it wouldn't be writeable.

Hybrid ISO saves MBR with boot code and partion table just for appearing as a writable media to OS, bootable DVD/CD ISO does not.

What Blaze is saying here is he can't write to usb stick (copy, remove...) and thus he cannot write usb drive but sure he can read it since he's able to get a file listing.

OK. FWIW This is the code I use to use to make BartPE ISOs.

Code: Select all

mkisofs.exe  -iso-level 4  -volid "BartPE" -b bootsect.bin -no-emul-boot -boot-load-size 4 -hide bootsect.bin -hide boot.catalog -o "D:\Users\Ed\PEBuilder\pebuilder.iso" "BartPE" 
if errorlevel = 1 pause
goto END

I interpret his use of the word "execute" to mean "not readable".

A little clarity

exactly.

I can clone ISO to USB, and fs of USB stick convert to isofs.
I can read isofs and copy data from isofs to another fs.
Copy any data from another fs to isofs is impossible.
Remove data from isofs is't possible too.

About "execute" I mean bootable usb drive, but this does not happen.

IMHO.

I thought that this tool transfer all data to USB stick and don't touch current file system and probably makes bootable USB stick.
Plus I can work with these data - I mean rwx :)

Sorry about my English.

the better and simple way to achieve this is simply mount iso image file and the copy content to usb drive, something like this (supposing usb drive is mounted in /mnt/usb):

Code: Select all

# mloop myimage.iso
# cp -a /mnt/loop/* /mnt/usb/
# uloop

mkisofs.exe  -iso-level 4  -volid "BartPE" -b bootsect.bin -no-emul-boot -boot-load-size 4 -hide bootsect.bin -hide boot.catalog -o "D:\Users\Ed\PEBuilder\pebuilder.iso" "BartPE"

Ok, so as you use -b option to create iso images you are creating iso file images with El Torito extension and thus they're bootable, as you can see in man page of mkisofs from cdrtools you are using:
-b eltorito_boot_image
-eltorito-boot eltorito_boot_image

Specifies the path and filename of the boot image to be
used when making an "El Torito" bootable CD. The path-
name must be relative to the source path and inside the
source tree specified to mkisofs. This option is
required to make an "El Torito" bootable CD. The boot
image must be exactly the size of either a 1200, 1440,
or a 2880 kB floppy, and mkisofs will use this size
when creating the output ISO-9660 filesystem. It is
assumed that the first 512 byte sector should be read
from the boot image (it is essentially emulating a nor-
mal floppy drive). This will work, for example, if the
boot image is a boot floppy.

If the boot image is not an image of a floppy, you need
to add one of the options: -hard-disk-boot or
-no-emul-boot. If the system should not boot off the
emulated disk, use -no-boot.

More than one boot entry may be specified, see
-eltorito-platform and -eltorito-alt-boot on how to
specify more boot entries. The first boot entry is the
default boot entry. Additional boot entries are
members for a multi boot configuration.

If the -sort option has not been specified, the boot
images are sorted with low priority (+2) to the begin-
ning of the medium. If you don't like this, you need
to specify a sort weight of 0 for the boot images.
