How to I resize .IMA file? I got this .IMA (2GB and various others zipped in a guide made by diddy) the problem is that I cannot resize the IMA file with ImDisk's "extend" feature. If I do that, it looses ntfs format and I'm not sure if its usable again.

No, this is "by design".ImDisk doesn't handle images with a MBR very well. It extends the image and the file system, but it doesn't update the partition table. So the filesystem size and the partition size don't match.
Maybe Olof can fix this?

IMDISK is a "filesystem driver".
Use VDK or Microsft VSS driver to mount the image as \\.\PhysicalDrive in order to get access to the MBR.

SureBut ImDisk can read the partition table of an image file to get the size of the partition to mount (at least I think that's the way it works). So it should be no problem to modify some bytes of the image file to correct the partition size. No need to mount it as physicaldrive if you can manipulate the image directly
Posted 15 February 2010 - 04:47 PM
Well I guess the ImDisk driver locks the image file while it is mounted. BUT ImDisk has write access to the filebut if you have the physicaldrive mounted, you have it all accesible, if the image is mounted in IMDISK, the whole image files should be "busy" and you would need to unmount it in order to access the MBR (in the sense of first sector of the image file). (haven't actually tried - needs to be tested and confirmed or denied).

Yep.btw. I just noticed that ImDisk extends the filesystem of a mounted partition even if other partitions directly follow the mounted one, screwing up not only the partition table, but the filesystem (and data) of the following partition as well.
Posted 15 February 2010 - 05:45 PM
And this is reason #2 for using \\.\PhysicalDrive
Posted 15 February 2010 - 06:38 PM
Well, I don't know either but a workaround could be using sparse files and a tool to enlarge them (when offline) before mounting.But then you need to have enough 'free space' on the virtual drive to extend the partition. And that most likely means you need to increase the file size of the image file. ImDisk can do this on-the-fly. I don't know if there are any virtual disk drivers that provide 'PhysicalDrive' access which are able to do this.

Just in case:Writing a tool to enlarge a file shouln't be a problem. I can give it a try if I find some time tomorrow
Posted 16 February 2010 - 03:22 PM
Ooookkkkk
So out of all this, I'm to assume that there are tools to enlarge IMA files? or TheK will write up something? I thought I was in page number 4 (There goes Lama back to read read
)
mkFile -r -g c:\test.ima 3Now you will have 1GB of free space available to extend your virtual parition.

There is. Read section How to create/mount raw disk image with FiraDisk 0.0.1.12 in opening post of FiraDisk thread. You can attach disk image but cannot boot from it.... there must be some command to "Attach" IMG file as another hard disk instead of copying IMA (or IMG) on RAM and then attaching it as HDD.

Partition Logic does not detect any hard disk
second, it maybe VirtualBox but I'm not surprised, how can a person simply rename file extension to change its format?
This concept did work in my media player (mp2 to mp3) but VBox it ceratinly didn't (it saw as Free space instead). While mounting it with ImDisk, it actually got mounted right (but not with 3GB, obviously the partition size has to be increased via partition logic type softwares provided that they're detected by something). QEmu also didn't recognize .IMA
