Apple computers and Micromat....?

So, here is my latest test of your collective knowledge...

It concerns the mighty Tech Tool Pro for Macintosh made by the fine folks at Micromat. This in my opinion is a great program that has helped me out of a jam or two!

My questions are these...

1. Are there any pitfalls related to installing an eDrive on a hard drive?
(True Tech tool Pro users will know what I am talking about here)

1.2 How does one delete an eDrive or re-partition it if the contents of the eDrive have been deleted? Is the only way to re format the entire drive?

2. Why do hear from full-time technicians that installing any such programs, be it Tech Tool Pro or Disc Warrior etc, on a hard drive a bad idea to do so?
Is it because one program may interfere with another if one was attempting to solve a problem with a specific utility program?

Thanks to all who join this discussion.

B/W G3, Mac OS X (10.3.x)

Are there any pitfalls related to installing an eDrive on a hard drive?

The major pitfall is that it takes up precious disk storage capacity.
There must be a minimum of 6 GB available on the source volume to create an eDrive. (TechTool Pro Help)
The other pitfall is that it can create a false sense of security. If the eDrive is on the same HDD which will need repair, if the drive fails entirely, as HDDs do after a while, the eDrive can do nothing about it. It will probably warn you on the way to failure, but it is no longer usable as an eDrive.

Remove eDrive
Pressing the Remove eDrive button removes the selected eDrive and returns the space it used back to the original volume. The Message Area will indicate that the eDrive is being removed during this process. (from TechTool Pro Help)

Why do hear from full-time technicians that installing any such programs, be it Tech Tool Pro or Disc Warrior etc, on a hard drive a bad idea to do so?
I answered this in your other thread. However, I have never heard anyone recommend not installing it on the boot drive. TechTool Pro recommends it. It is recommended that the eDrive be on a different disk for the reason I mentioned earlier in relation to disk failure.

Good luck.

Thanks again for responding to my discussion again, Cornelius.

Heres a doozey for you though, I made a colossal blunder with it!
In trying to remove it, without the use of the function in TTP (as in booting from the TTP disc itself lets say, and selecting "remove eDrive) I deleted the contents of the eDrive!

Now TTP does not even recognize it!, I cant seem to be able to re - partrition it back into the main drive, (I guess my inexperience with all this is really showing here, how embarrasing!)

My fear is, unless I reformat the entire drive, eDrive, HD and all, this "phantom" eDrive will now occupy a certain amount of disk space which I will not have access to until...well until the HD fails (as you stated in the other thread, they eventually all will) or until I refort it.

any suggestions would be appreciated.

I suggest that you completely uninstall TechTool Pro using AppDelete and all related files, then reinstall and update TTP without the eDrive, if you no longer need it. Do you think that is feasible?

Good luck.

Indeed, I may just do that.

Now the machine is no longer in my possession, I will have to do so at a later time. If this procedure does not work then I will reformat the HD completely.

Thanks for responding.
