DE-Storage Compressed Format Glitches
Posted: 15.01.18, 21:29
So I've been playing around with the new DE-Storage format, running a few cases with it and I'm finding some glitches. The speed issue I earlier reported seems to have been resolved by upgrading my CPU to a $1000 Ryzen Threadripper with 16 cores, so that's better now.
One glitch I've found is that you can only have one DE-Storage task open in each instance at a time. Otherwise, it gives an error about being out of memory (which can't be true I've got 32Gb). So I can't have one task open for imaging and also open another task to copy some files or check something.
Another glitch, which has me confounded, just happened today. I had a task that was 100% imaged with no bad sectors. It was from a DVR so it was a 100% full disk beginning to end. The customer wanted a clone drive, so I did a data export to another drive to provide the client. It got to 99.99% (actually looks like it finished) then spit out a bunch of IO errors regarding the source. I checked the target/destination drive and only about 20% of the data even copied. So for 80% of the time it was just pretending to write data, or was just writing zeros instead of writing the actual data.
I think this format needs a bit more testing.
