mount .dsk file

I have a .dsk file which is an ext4 formatted hard drive image created with R-Studio. R-Studio is for Windows and the image was created in Windows.

file image.dsk:

Code:

image.dsk: Linux rev 1.0 ext4 filesystem data, UUID=702bca38-459b-44d3-908f-eade1955f3cb (needs journal recovery) (extents) (large files) (huge files)

sudo mount -t ext4 -o loop,ro,noexec image.dsk /mnt/tmp:

Code:

mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error

sudo dmesg | tail:

Code:

[212374.594038] EXT4-fs (loop0): bad geometry: block count 488315232 exceeds size of device (488315216 blocks)

sudo /sbin/fdisk -l image.dsk:

Code:

Disk image.dsk: 1.8 TiB, 2000139124736 bytes, 3906521728 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

I get too many weird errors trying to run R-Studio in Linux, so I think it would be easier to mount the image, so I was wondering if anyone here wanted to take a stab at it.

I'm hesitant to fsck it since it took 20 hours to create the image file and I don't want to ruin it somehow. Maybe someone knows better than I do.

Thanks.

It appears you left out the -o flag - also there shouldn't be a colon at end:
sudo mount -t ext4 loop,ro,noexec image.dsk /mnt/tmp:

Should be:
sudo mount -t ext4 -o loop,ro,noexec image.dsk /mnt/tmp

Oh, thanks. That was just a typo in the post, when I used the command I did have the -o option.
