Basically I've got to write a report on EnCase and how I found it. Thing is I'm struggling to find many disadvantages. I'm only in first year and to be honest Forensic Computing is more of a side stream, so I've not had any experience with other Forensic Softwares. If any can help me please do!!!  

Excuse me for being dense but unless your project is to do a survey, aren't you asking the community to do your work for you?

After all, in your original post you said that you had to write a report on EnCase and how I found it.  

fair enough it does seem like that
however I have wrote about how I found it but I'm told I also need to include the advantages and disadvantages of the EnCase software. Having never used another piece of forensic software I can't really compare it with anything else so I was wondering if anyone knew of any specific disadvantages other than cost.  

Did you find it more difficult to use or understand or get useful information from than the software you use in your primary field of study?  

Download the demo version of FTK and play around with a small drive, be it a flash drive, floppy disk, or a small hard drive with less than 5000 files on it (the demo's limit). I assume from your posting that you have some experience with EnCase? Try some of the things that you did with EnCase to see if there are differences.

Here's another hint, this has been discussed on here before. Do a search to try to locate. it. I believe there was some discussion as to which is better, and in that there were pros and cons of each.

Hope that helps.  

electrogirl there is also a demo of Encase software, i got some spare disks with it if you want one PM me.  

Thanks for your help guys.
@CforPro, I searched and found some useful discussions so thank you for suggesting that.
