PC-3000 Forum

The recent versions of PC-3000 Express/UDMA-E/Portable Ver. 6.4.14, Data Extractor Ver. 5.7.7, PC-3000 SSD Ver. 2.5.8 are available now! The updates bring a variety of enhancements, including new modes and features, a wider range of supported drives and processes to be run in the background, and much more!

Take a look at all the new features here

Hi

I see a new button (function): WinDisk.
I don't see nothing on the feature log.
Can you explain exactly what it does?
Thanks

This new version of DE is putting all copied files in a folder called "Root" when I copy the customers data to an external drive. There is no "Root" folder on my patient drive. This doesn't happen in the previous version. Very annoying as I have to copy everything out of this "Root" folder and delete it. It even makes a "Root" folder in the "!Problem" folder. Can we turn off this "Root" folder creation?

So, I'm playing around today with the new compressed image function of DE. As a test I took a full drive and cloned around 270Gb which it was able to compress down to 140Gb size which is a nice savings of disk space. However, I do notice that there is quite a performance drop in speed when it's reading areas that are full of data. In areas that are mostly blank it'd read at full speed 120Mb/s, but slowed to around 50Mb/s when there was a lot of data.

My questions are this:

1. Will the option to select the compression level be available soon? I see a slide bar there, but it doesn't allow any adjustment as of yet.

2. How well optimized is this compression for multi-core processing? Would it be advantageous to upgrade the host system to something like a Ryzen Threadripper which has 16 cores? Or, is the speed limitation more of just a software limitation? (I see my current processor is hitting around 95%, but not quite maxing out so I don't know if the CPU is the slowdown)

Any insights you can provide as to that? I'd love to take advantage of this feature, but I can't very well have drives all imaging at low speed. A CPU upgrade I can certainly do if it'd be a big benefit.

WinDisk button allows to add the drive to Windows Explorer and work with the drive, powered by PC-3000, as with common HDD connected to PC directly.

This ROOT folder creation is driving me nuts every time I have to copy data off an image. Probably going to go back to the previous version.

I went back to the previous version.

+1 the ROOT folder is annoying.
But moving data out of ROOT folder takes only a few secs.
So will not go back, but I hope it gets fixed.

During the task creation, if we select DE-Storage as the destination drive, there is no possibility to change the compression rate because it's locked for PC-3000 own forensic format.
But, if you want to change the compression rate, you can choose any other forensic format by pressing right mouse button onto partiton in folder tree, for example, then Export to forensic format->Add, select the file type and here the compression rate selection is possible.

Yes, definitely, more cores - more perfomance in compression procedures.

Thank you for replying to this. I'm planning to upgrade my host system as a year-end tax write-off spending item. I'll let you all know how much faster it is with a 16 core processor. I did notice that when I had the compressed imaging going it was running 82 separate CPU threads so it seems it'll be able to take strong advantage of a lot of cores.

This version has several issues, the "ROOT" has been already mention, also when I open my utilities keeps asking me to choose "Utility run parameters" even when I click on "Use as default". DE keeps asking me to mark "Read only drives" every time even when they area already marked. DE does no gives the ETA to copy data any longer

Do you know when we are going to get RAM access to WD Spyglass drives? Just curious if its weeks, months, years away. Thanks.
