  1. Moving data to the Pool while retaining the data on the same drive is called seeding and it is advised to stop the service first (https://wiki.covecube.com/StableBit_DrivePool_Q4142489). I think this is because otherwise DP might start balancing while you are in the process of moving drive-by-drive. I am not sure but I would think you would first set settings, then do the seeding. (I am pretty sure that) DP does not "index" the files. Whenever you query a folder DP will on the spot read the drives and indeed show the "sum". Duplicate filenames will be an issue I think. I think that DP measures the Pool it will either delete one copy (I think if the name, size and timestamp are the same or otherwise inform of some sort of file conflict. This is something you could actually test before you do the real move (stop service, create a spreadhseet "Test.xlsx", save directly to a Poolpart.*/some folder on one of the drives, edit the file, save directly to Poolpart.*/some folder on another drive, start service and see what it does?). DP does not go mad with same folder names, some empty, some containing data. In fact, as a result of balancing, it can cause this to occur itself. I have no clue about snapraid. I would speculate that you first create and populate the Pool, let DP measure and rebalance and then implement snapraid. Not sure though. You may have to read up on this a bit and there is plenty to find, e.g. https://community.covecube.com/index.php?/topic/1579-best-practice-for-drivepool-and-snapraid/.
  2. Yes, DP does not need nor use drive letters for the underlying drives.
  3. Do you have this option checked in Scanner: Settings -> Advanced Settings and Troubleshooting -> Advanced Settings -> DirectoIO -> Unsafe check.
  4. I had DP running on a Celeron 430 or somesuch, 8GB without any issues. DP is rather lean and simply does not need much.
  5. If you are comparing single SSD vs a Pool of spinners, then yeah, the SSD will load way faster. However, if you compare a single HDD vs a Pool of spinners then the difference should be negligible (or perhaps sometimes a bit better but I have hardly ever seen that happening).
  6. And here I was thinking HBA==IT.... Turns out I was wrong.
  7. So I don;t really know. I have a SAS HBA, an IBM1015 butcalled Dell H310 or somesuch. I never understood the LSI chip/card numbering. In any case, I did have to get the latest bios for my card, P20* or something. Also, with Scanner, I had to Settings -> Advanced Settings and Troubleshooting -> Advanced Settings -> DirectoIO -> Unsafe check. Never had an issue with that and SMART is read. I would try the Scanner setting first, reboot and see how it goes.
  8. Not a dev either. Another problem might be that once one starts writing a file, it may not be yet known how large that file will be. Sure, a simple copy should not have that issue but what if you save a stream of as yet unknown length? Writing to the disk with most space free seems to be the safest option (and personally, I like safe). Also, I find it hard to think of a scenario where a subsequent reshuffle of files would measurably impact performance.
  9. That's why I'm asking for the exact model.
  10. Yes, you can simply uninstall. no files will be lost. Unless you do something weird.
  11. So many have no such issues at all. Could it be there is something somewhat specific to your situation is going on? Some here will be trying to help but it helps if you provide a bit of sensible information. So, again, have you checked Event Viewer (for IDE/ATAPI/DISK errors specifically but any other errors might be relevant) and what model HDD s this exactly? Also, can you try to copy some represntative files to that drive F:\ instead of to the Pool?
  12. Have you checked Event Viewer and what model is thus exactly? And if the data you want in the Pool is already on the disks you want to add to the Pool, then there is a much faster way of getting them in the Pool.
  13. Adding a drive does not mean that you can not store data outside of the Pool on that drive. The Pool data is located in a hidden folder (PoolPart.*). I think you want to move the data outside of the Pool on that drive into the Pool. This is called seeding and how to do it is described here: https://wiki.covecube.com/StableBit_DrivePool_Q4142489
  14. I know there is an SSD Optimzier plugin but AFAIK it only serves as a write cache, you can't dictate which files should be on the SSDs for fast reads. There are also File Placement Rules where you can map certain folders to specific SSD/HDDs but there I don't think you can use a single SSD for both functions (not sure, maybe you can).
  15. Remeasuring just checks whether the duplication that is actually there agrees with your settings. So if you have no duplication as setting but some files are duplicated, DP will correct that too.
  16. Don't panic. If the drives do not show up in BIOS, chances are you made some sort of silly mistake that will be easily correctable. Just take the drives out, connect just one and see if you can get that one recognised. If that works, try it on a different port and with a different power cable. Add on drives as you go. I had a PSU with detachable cables. None of my HDDs worked. Turned out cables were not connected to PSU. A brief scare for a few minutes but only something silly. Probably something like that with you.
  17. I don't have enough info to try to diagnose this but remeasuring seems like a sensible thing to do. Screenprints illustrating what you say is the case help.
  18. Have you tried reading https://stablebit.com/? Anyway, DP combines volumes into a large NTFS volume. It can have redundancy if you want. Either for the entire "Pool" or just certain folders therein. If one drive fails, the most you can lose is the data on that one drive. The data on the other drives will still be available. If all was redundant (we call that x2 duplication) then the Pool will reduplicate the lost files, provided you have enough space. Each drive you add to the Pool is not exclusively for the Pool. It will create a hidden PoolPart.* folder within which the Pooled files will be stored. You can use the rest of the drive as well outside of the Pool. DP simulates a NTFS drive but it also uses plain NTFS on the drives that are part of the Pool so any recovery tool that works on NTFS will work. x2 duplication is a bit like RAID-1 in the sense that it requires twice the space to store data. Parity/checksums are not supported by DP. You might be able to learn a lot actually from just reading a few threads here on the forum.
  19. Why not use the 30-day trial period so that you have time working thus out with support?
  20. What you can do is deactivate the license on the old machine, build/install the new one and active the license there. Write down or somehow copy the license key. Deactivating the key will not delete any files in the Pool. I think the Pool remains accessible just read-only perhaps.
  21. What I think I know and would do is : Yes, you can use the C:\ drive as part of the Pool. The OS itself won;t be in the Pool but part of the Pool will be written to the hidden Poolpart.* folder that will be placed on the C drive. Personally, I would consider doing it with a separate partition as it makes it easier to backup/restore/reinstall the OS itself. It is in fact possible to use one SSD with x2 duplication (even though I consider it a bug and would not do it). You would have to split the x2 Pool first into two x1 Pools and then create a Hierarchical Pool consisting of the x1 Pools and let that Pool have x2 duplication. You'd be doing a lot of seeding. The SSD would have to have two partitions, each would serve as SSD cache for the x1 Pools. Haven't done it, it has been written in the forums, I would not do it. AFAIK, there is no immediate/delayed duplication option in DP (but I could be wrong). Does Plex use Hardlinks? I don;t know Plex nor understand what hardlinks are but DP does not support them as I read on this forum. Still, many use Plex so some setup must be successful. Anyway, that is going to be a nice server (and network)! GL.
  22. This is what you are looking for: https://www.google.com/url?q=https://wiki.covecube.com/StableBit_DrivePool_Q4142489&sa=U&ved=2ahUKEwjwmvXEvNXqAhWQ2aQKHW54CW8QFjAAegQICBAB&usg=AOvVaw2GKZPsTgAT1LC_a4XMvhJB
  23. Yes, drives larger than 2TB are not supported by MBR. So you had to convert to GPT if they were MBR. That did not increase space, it just allowed to access the entire drive. You already have access to your entire 16TB drive.
