Mounting larger iso files

Post by **ayu** » 15 Dec 2008, 16:35

I'm trying to mount an iso file, but I think it's from a dual layer disc or something because it gives me

mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

The file is 5.5 GB, and I have had these issues before, but I don't think I ever got it solved =/

I tried to mount it with the regular command

root@enma:/home/cats/Desktop# mount -t iso9660 -o loop rld-fou3.iso /mnt

maybe , try and see if it does the same thing with windows, perhaps a virtual machine useing a iso mount program like daemon tools, magic iso, alchohol 120%, ect.. one of those kinds of programs

ive mounted large files like that in windows , not linux sorry

Don't have Windows though =/

I have it on my lappy, but the lappy is only for work, so I wont install any tools like that there ^^

hm, I am not sure if one of these is the reason, but you have not made a subdirectory (don't know if you can mount into /mnt directly) and the mount options are usually done in a different order, so just to be sure try:

Code: Select all

mkdir /mnt/iso
mount -o loop -t iso9660 rld-fou3.iso /mnt/iso

Yeah you can mount into mnt directly, tried with a regular iso file

damn, either DVD DL completely incompatible, or maybe it's just in context with that specific DVD drive.....have another drive so you can check?

It's an ISO file ^^

Reason I said DL was that maybe it was ripped from one, and maybe that made it "different" in som way, I'm not sure =/

ok, it seems DVD images are NOT really iso images, the definition of an iso image is that it uses the ISO9660 file system, DVD images don't, they use the UFS file system.

so try this:

Code: Select all

mount -o loop -t ufs rld-fou3.iso /mnt/iso

nope, same error

Post by **bad_brain** » 17 Dec 2008, 04:38

damn...ok, looks like the image is really corrupted...

VMware will not harm your lappy

maybe slow it down a little thats it.. run windows on VMware just for that game and you should be golden

Why run Windows on VMware on a computer that runs Windows?

No but, VMware doesn't work really good with games, and especially not the newer ones ^^

Also, going around the issue is unacceptable =/
