A drive dropped out of the Pool and it took some time until I discovered this. I expected to get an email, but didn't receive one. How ist the email send? How can I test, whether email notications work (e.g. "Test notification" button)?

With BETA 3116 both the wrong disk size and the wrong error scanning has gone. Thanks.

With BETA 3116 both the wrong disk size and the wrong error scanning has gone. Thanks.

I have to drives: one USB-Drive and one of SATA drive attached to an external eSATA case (the latter of which reports a wrong disk size of 1000 instead of other tools and the windows disk manager). I did a "chkdsk /f /r" which also scans the surface and I have no read errors at all! However, when I start a StableBit scanner, it produces lots of read errors. What is wrong?

Could you please add an option to BINARY compare the files for integrity? This possiblilty was also often discussed in other threads since a couple of months. Currently there is no means of really verifying integrity. If I have 3x duplication and one file is differs from the other, then it is easy to have the third copy replaced by the others ones. Also with 2x duplication a conflict should be detectable. I also had the problem, that I copied some 100 GB of data from one disk to another and a binary comparison afterwards showed differences. This problem cannot be detected by DrivePool currently and should be fixed, at least with the command line option and even better in the management interface, to have a scheduled full or partial verification.

Yon the built in external eSATA port. Which information do you use. BitFlock id 388I14TA. However: The Window disk manager also gets the correct size of the disk. I also tried HD-Tune (freeiware and professional version) which also reports the correct size. So still think it is a bug.

I have an Seagate ST31000529AS drive attachted to to x510 Datavault server eSATA case. StableBit reports 1,8TB as the disk size, but the disk has only 1TB. See attached screen shots. I have version 2.5.2.3103 BETA

Does it also do a binary comparision of the file parts, or does it only check, if the file is there and timestamp and size match?

The recalculation bug seems to be fixed in 2.2.0.634, but the "unduplicated" problem is still there, even though I did a "remeasure" with this version. Now I have 2.35MB of "unduplicated" files, but don't now, how to find out which files are not duplicated. Also why does a "remeasure" not fix the problem. There should be 0 "unduplicated" files.

Any news on the verification checker or Fileafe?

Any news or improvements on the verification tool?

The "recalculation bug" from point 2 is till there in the latest beta.

How exactly do I turn on verification and how to read the results? I worked with Raid mirroring in the past and had inkonsistencies there. Recently I had a drive, where I discovered that some files were not identical to copies I had on another drive (laptop), even though the files did not change and also all files were readable and the SMART-attributes did not show anything special. So we really badly need a verification tool which can make two types of checks (mayby configurable): 1) Check whether all files have been duplicated formally (my issue of not duplicated files is still open and I cannot find our what the problem is. Also you were not able to the solve the problem from the log files I send you). 2) Check binary integrity of the duplicates. So please: Make a verification tool, where we can check the type 1) and type 2) integrity as soon as possible. Also this tool should be schedulable (e.g. once a month). Even more urgent is ANY way to resolve existing inconsitencies (like my problem of having several MB unduplicated and the "recalculation loop").

I upgraded to the latest beta 2.2.0.599 and both problems are still there. But since this version also the "Troubleshooting" option is missing, so I cannot activate logging. How to do this with this version?

I didn't find any information about the SMART data dialog and its interpretation. Questsion I have are: * Some attributes have a green background. Which is the meaning? * How to read the precentages? * How to read the bar graph? It is some red bar and a black bar. * It is possible to see the attribute id? * Termperature is logged and there is a graph. Is there also a graph and history for other attributes (would be fine).

Any news on that? I would like to have a bitwise integrity check e.g. once a month. Any there any means to do it now? Also I would like to do it manually, e.g. after chkdsk problems.

1) I also have the problem to find out the "unduplicated" files? I still have 5,6MB of unduplicated out of 4TB duplicated. Which are these 5,6MB files? 2) There seem to be a problem with the "File Protection > Folder Duplication" dialog: When I open this dialog, all directories are set to x2 and it starts calculating. However this process never finishes but starts over again and again after about 60% of the pool size. Also when it starts measuring the readings for "size" and "duplication" are identical but differ after some time I have DP version 2.1.1.561.

Are there any news to solve the problem? The fix should not be too difficult.

I have a single Pool which should be completely duplicated. However after some days now the dashboard shows 43GB out of 3,5TB non-duplicated files. The last organisation took over a day the organisatio bar now just shows "not optimal", but is almost completely filled green. Why didn't Drivepool duplicate all files? How can I find out which files are not duplicated? How do I now when the duplication process is really finished, i.e. all files are protected like specified?

I still have problem to understand the state of the pool and the balance marks. 1) When I have a mixture of duplicated and unduplicated folders in the pool, how do I now that the duplication is complete (i.e. all files which should be duplicated are indeed duplicated)? 2) I have two drives in the pool (see atttachment) Over the unduplicated files there is a mark showing -38,6GB. The other drive has + 38,6GB. What does this mean. Does it try to move 38,6GB from one drive to the other?

As said, in the balancing I said, that a certain folder must only be on a certain drive, and also checked "Never allow files to be placed on other disks". But the folder is still not on the disk I want. I wanted to wait until this empty folder appears on the correct disk, where the data is already outside of the DrivePool directory, to be able to simply move the files on the same disk into the hidden DrivePool directory. So I would expect that hard file placement rules for a certain disk shoud be obeyed quickly, even before DrivePool starts balancing the drives for space distribution which is really just optimization not hard rules as the file placement rules (never allow files to be placed on other disks). Two other questions: Why is resetting neccessary, after moving files to the hidden pool directory? I did migrate lot's of files without resetting and without starting and stopping the service and it seems to work. Was this dangerous or to I risk inconsitencies? How does DrivePool on which disk it finds a certain file? I suppose "Remeasing" builds up a database of where to find files. So after moving files to the hidden directories, DrivePool would needs a "Remeasuring".

As far as I remember it was just "Waitint to scan" nothing more. Maybe there was a tool tip? In the GUI there is a scanner setting: "Don't interfere with other disks on the same controller". This was unchecked. What is the difference to ScanMaximumConcurrent?

Yes as you said, you have to know on which disks are files stored. The hierarchy is as follows: Files are stored on filesytems -> Filesystems are stored on volumes --> Volumes are are stored on either partitions or dynamic disk space ---> Partitions and dynamic diskspaces are stored on disks You are only interested in volumes (containing files) and disks, but not on the middle part of partitions and dynamic disk space, so you can query directly for volumes and disk. In diskpart (but also possible with Windows API of course): Query for all volumes: list volumes Query for all disks: list disk Query which volumes a disk contains, e.g. disk 3: select disk 3 detail disk

Yes new dynamic disk use only one (MBR) or two (GPT) partitions to store all data and metadata. You only have "volumes" no partitions any more. If you type "detail disk" you see the volumes on the selected disk. Here is a good article on the disk layout on dynamic disks: http://www.howtogeek.com/school/using-windows-admin-tools-like-a-pro/lesson4 My questions is: What does DrivePool has to do with partitions? Shouldn't it only look at volumes?
