Pros
Simple, fast, and stable. Runs on a tiny foot-print too. Handles errors as you'd expect. Would highly recommend for iso editing work.
Cons
None so far!
Summary
Wouldn't let go!

Undisker seemed to run fine until the end of the process. When it reached 100% completion of the creation of an ISO file, it didn't ever stop. It hung at 100% and kept accessing my disc. I couldn't end task on it; I couldn't end process on it. I had to take drastic action and bring in KillBox to make it quit. Even so, it took twice with KillBox! I'ma delete it from my system right now.
Summary
Did what I needed it to do

Summary
It may be somewhat slow in unpacking an ISO file, but it did the trick quite nicely. Haven't used it much and certainly wouldn't pay the full registration price unless I really needed it, but again, it did what it was designed to do and there weren't any glitches.
Doesnt' create iso

Developer’s Description

By QSX Software

Create disk image files from your CDs and floppy and hard disks and write them back to disks.

Undisker is a disk image utility that can open, create, and extract ISO files. ISO files are images of CD-ROM disks; they are widely used for storing contents of entire CDs. Usually, you have to burn an ISO file on a CD to see or extract its contents, but now you can simply open it in Undisker. Undisker can work as an ISO extractor: you can open ISO files, browse them, and extract their contents to your hard disk without burning the ISO file on a CD. Undisker can extract ISO images created by all popular CD recording programs. You can also use Undisker for creating ISO images. Undisker can create ISO files by capturing your CD-ROM disks.

You can use ISO files for creating backup copies of your CDs or for transferring CDs through the Internet. The undisker interface is easy to use and familiar for anyone who has used WinZip or Windows Explorer. Drag-and-drop support allows you to handle disk image files just like ZIP archives--you can extract any file from the image by simply dragging it to the desktop, or you can view files by double-clicking them just like in Windows Explorer.
