  1. I have never experienced your problem of files getting corrupted when moved off the cache drive to the archive drives in the pool. I have never used the DrivePool Verify After Copy feature because I have not had the issues you are reporting. I don't know how DrivePool would respond if a verification failed, but I suspect it will alert you and will probably leave the file on the cache drive and try again the next time it balances. But, I really don't know as I have never used that feature. I once had a problem with a USB 3.0 HDD caddy and transferring files into/from DrivePool. Files were getting corrupted in that transfer and I solved that issue by plugging the caddy into a USB 2.0 port and slowing all the transfers down. For some reason, my corrupt file transfer issues went away with USB 2.0. Maybe the caddy had a buggy USB 3.0 engine? I would still encourage you to use something like MultiPar with verification files to narrow down your issue. If you had a test folder(s) with files and .par2 files, you could verify the folders first and then transfer those files to your DrivePool cache. You could immediately run a verification on the files in cache to see if they transferred without corruption into DrivePool. Then after the cache flushes to the archive drives, run the verification on the folder again using the .par2 files. In that way, you could verify the files on your initial device or computer, in the DrivePool cache, and in DrivePool archives. Also, you might consider trying a different interface cable on your archive drive to see if that makes a difference. Cables can go buggy and cause intermittent corruption. Just enough to drive you crazy because you probably can't verify it was a bad cable unless a different cable solves your issue. Good luck. I hope you find the solution to your corrupted files issue.
  2. I have not experienced your specific problems, but I have a few things I might try. You might want to turn on the verify after copy option. Goto Settings Cog>Troublshooting>Verify After Copy. This feature is normally turned off because it will slow down your system. However, in your case with suspected bad copies, it might be worth it to check out that feature. I use the free program MultiPar to create .par2 files for file verification and rebuild. In your case, you would tag the movie file, or folder, and create .par2 files. When you run MultiPar on the .par2 file, it will verify if the original file is intact or if it has been damaged. If damaged, it will attempt to repair the file(s) with the .par2 files you created. You can adjust the % of .par2 files for rebuild anywhere from 0% (index only) to 100% complete blocks for total rebuild. I have my MultiPar set to 10% .par2 files which is enough to verify the file(s) in the folder and will rebuild some damaged and lost files. Of course, I would recommend a good offline backup plan. If your files become corrupt, and MultiPar cannot rebuild the damaged files with the .par2 files you created, then you can pull the backup files and reload them. I really don't understand why DrivePool would be corrupting your files when it balances the pool, but maybe some of these ideas will help you narrow down the cause of your problem.
  3. My DrivePool SSD as a front end cache has been working just great for about 1 year. However, I recently experienced something with my computer that reset my DrivePool settings, removed the SSD cache, and spent weeks telling me that Duplication was inconsistent. Since DrivePool was in an error state, I attempt to use "Troubleshooting" and recheck duplication. Never fixed itself. Thinking my DrivePool was reaching its max capacity, I added another 4TB drive to the pool and within couple days DrivePool was able to fix the Duplication inconsistent situation. So I added my SSD drive back into the pool, as an SSD, and reset the settings to where I think they were set before I had the problems. Unfortunately, my SSD cache no longer flushes to the archive disks as expected. Before, I had the SSD set to flush at 100 GB and had no problems. Furthermore, if I wanted to force a flush of the SSD cache, I would just tell DrivePool to rebalance itself and it would flush the SSD cache to the archive disks. Now, DrivePool will write to the SSD cache, but it does not flush the data to the archive drives when it reaches the 100 GB limit, and when I attempt to force a manual flush of the SSD it will not work. So my SSD eventually reaches a point where it is almost full and then new data will be written to any drive on the pool with the most free space. Something got broke and I don't know how to fix it. For the time being, I have to manually "remove" the SSD to flush the cache and then add the SSD back to the pool. Although this is a viable work around, it is not a solution to my problem. A SSD cache that will not flush itself automatically is not really a cache. Any suggestions would be much appreciated.

    Blank UI - Drivepool

    I have not had your problem. However, when I do have any problems with the DrivePool UI on my server, I usually just restart the server and the problem(s) seem to go away. If that does not work, I might suggest uninstalling/reinstalling DrivePool with the latest updates. Failing that, I would suggest contacting support and open a ticket. Like many issues, you might not know if this a Windows OS issue or something to do with the DrivePool UI itself. FWIW, I have experienced unexpected results on my programs after Windows completes an update. But usually a reboot solves these temporary issues. Hope you get your problem fixed.
  5. If you want to protect your data, then you really need a good backup plan. IMHO, no online pool system - RAID, DrivePool, etc... - is adequate to protect your data. But that is just based on years of having these online systems fail and data not backed up being lost. As to your specific concerns: 1. RAID 1 - takes a lot of HDD to mirror your data. Does everything in your pool need to be duplicated? If not, then RAID 1 may be too costly as your pool size grows. 2. DrivePool w/ Duplication - I only have a few directories selected for duplication in my DrivePool. Duplication in DrivePool is not designed to be a backup solution. It is there if you have a HDD failure and you could probably recover the pool faster from the duplicate copies. However, if you have some kind of file corruption, DrivePool cannot tell you if the original or the duplicate copy, or both have been corrupted. 3. DrivePool w/o Duplication + Scanner - Scanner might be able to save your data is the HDD has signs of pending doom and there is time enough to evacuate that drive. However, in my experience, with these newer larger TB HDDs, you might not have enough time to evacuate the drive before it fails hard and loses all data. I had a couple HDDs that were starting to fail and they were able to be evacuated without data loss. Hurray! However, I had a couple other drives that alerted and died within hours with no where near enough time to evacuate the drives. Lost data on those drives. Good thing I had a backup plan and archive HDDs stored elsewhere. Other options to consider.... 4. DrivePool with SNAPRaid - there are a number of people using DrivePool for their main data and SNAPRaid to offer recovery options. I personally don't use SNAPRaid because I have very little data on my DrivePool media storage center that needs that extra protection. But maybe your situation is different. 5. DrivePool with MultiPar - This is my method. I use Multipar to create 10% .par2 files for folder verification and rebuild. For my applications, 10% .par2 files is enough for me to verify if the files are still all there and intact, or if some of the files are missing or damaged, then there is probably enough .par2 file blocks to rebuild the damaged file(s). You can set the .par2 file setting all the way up to 100%, but then you would probably be better off with DrivePool duplication or RAID 1 options. I prefer to use MultiPar on my album folders, because DrivePool will send your album tracks to any number of HDDs in your pool. If you lose a track or two from a HDD failure, then MultiPar will fail verification and attempt to rebuild the missing files. Since I have all my data backed up on HDDs I keep in the closet, I don't really worry too much about lost data and if there are not enough .par2 blocks to rebuild the folder, then I'll just pull out the archive HDD and reload that album if I still want it. DrivePool itself cannot tell you if the folder is intact with all associated files, and if the data was damaged somewhere, then your DrivePool duplicate copy might be damaged as well. MultiPar will tell you if the files are verified or not, and you can decided what to do after that. Anyway, good luck on setting up your system.
  6. Don't have an answer to your question, but just noticed that my DrivePool balancer settings were automagically reset and my SSD was no longer working as my front end cache. So, I am trying to figure out what caused DrivePool to lose its settings. I have spent the past few days trying to tell DrivePool that my SSD is not an archive drive, but it still treats it the same as all my archive drives. I don't know why my settings were changed, but I'm having a problem getting DrivePool back to where it belongs.
  7. That's a nice looking chassis you have. 45 HDD's - nirvana! But let me say that I really don't know much about your type of setup because I have never used one. What has me most confused is that your card is for a RAID system. Do you have your controller card and chassis to run in a RAID system, or are your drives listed separately in file explorer? AFAI, DrivePool was designed to work with regular NTFS drives in a non-RAID environment. I have about 19 HDDs connected via USB 3.0 on my system, and it works fine. But I do not know how DrivePool would talk to a RAID controller. So I might be totally off base, but since nobody else has chimed in on your concern, I would be looking at RAID card and maybe that is slowing down your transfer speeds. FWIW, my USB 3.0 drives can transfer data about 120 MBs from my SSD to the archive drives. All my USB 3.0 drives are standalone drives, but I don't have drive letters assigned to the pool drives because DrivePool does not require drive letters. I hope someone can help you. DrivePool is a great software program, but I suspect you might have a hardware issue somewhere with your setup.
  8. My MediaSonic 4-disk ProBox bit the dust last week. So 4 HDDs in my DrivePool were reported as missing. For better or worse, my DrivePool is now up to 19 HDDs (via USB 3.0) and sitting at about 80TB. I was able to remove some HDDs from USB enclosures I had in storage and finally got those 4 missing HDDs from the pool back online. However, DrivePool is not liking the new pool setup. After the missing disks were put back online, DrivePool measured the pool, which seemed to go OK. But then it did a duplication check and erred out on that task. So I forced a trouble shooting duplication check and for the past 2 days, DrivePool has been Measuring... Duplicating... Calculating... etc. With an 80TB DrivePool, it appears that a task is working on the animated status bar flashing, but I have absolutely no idea what % of the task is complete, or if the task is hung up and not progressing. It can be flashing the exact same task on the status bar for hours and hours, overnight, and into the next day. I have just been letting it run on it's own, because in the past I have seen that DrivePool does eventually seem to correct itself - it just might take a very long time. And with an 80TB DrivePool, I am seeing that it is taking over 48 hours and still counting. My suggestion is to add a percentage complete display to the task bar so a person can verify the program/task is still working and not hung up. FWIW, I know all my data is still safely on the HDDs that were in the ProBox. I really don't care if DrivePool takes a long time to correct itself (with an 80TB DrivePool) as long as the task is eventually completed. I just want to be sure that everything is still moving forward and not hung up in a death loop.
  9. @Rob Manderson, Thanks for the offer. Attempted to send you a PM with some info.
  10. My ~10 year old MediaSonic ProBox died today. Will no longer recognize the USB interface. So my DrivePool is now down hard because I have 4 drives offline. At first I was just going to replace the old MediaSonic ProBox with a new one. However, current price on the MediaSonic ProBox is now close to $200. When I bought my ProBox, it was $50. OK, sticker shock. But this leads me to question other options. Individual USB enclosures are around $25, so about $100 for 4 enclosures to replace the ProBox. Have also looked at dual docking stations for about $36 each, or $72 for my 4 drives. Are there other options I have not considered? Don't know if anyone here has some recent advice on enclosure purchases, but would appreciate any help in deciding how to move forward. Thanks.
  11. Follow up: I moved my CineRaid USB Docking Station to a USB 2.0 port instead of a USB 3.0 port, changed the TeraCopy default from asynchronistic mode to OFF, and checked the default copy/move command to verify. Since then, I have had no further problems. I suspect the main benefit was moving the USB Docking Station to USB 2.0 and just slowing down everything. But that is just a guess. At any rate, I no longer have the problems I was complaining about in this post.
  12. I don't think DrivePool would like to see 2 hidden directories with the same directory names. If you took the HDDs offline, I think you could simply cut and paste the whole hidden folder within the drive containing 6TB of information, and then only connect the new drives back into DrivePool. IIRC, DrivePool only checks for the hidden PoolPart directories and does not care what the HDD serial number or name is. But you don't want 2 HDDs with the same hidden directory names. +1, that is how I would go about this transfer. Then I would "remove" the old drives using the remove command in DrivePool and let DrivePool clean itself up. That has happened to me, too. So I have one computer without DrivePool on it and that is how I perform any and all "offline" tasks with DrivePool HDDs.
  13. I'd like to have a 256PB disk, too! If upgrading to 2.3.0.1244 Beta does the magic, I think I'll upgrade now! More seriously, I have not seen this issue with v2.2.5.1237 Stable, so let's just hope it's a beta issue that can be worked out before final release.
  14. What is the size our backup system file? Is it possible to write the backup file to your system HDD first, and then transfer it to DrivePool? I have never seen the Status_Wait_1 error you mentioned, but I don't use the "old" Windows Backup System in Windows 10 (Labeled as Windows 7 Backup) that you mentioned. I have used some other backup software, and it worked fine on DrivePool. Assuming you have at least one pool drive that can accept the complete system backup file, I don't know why the process is timing out on you. But I have never tried to write a file that takes an hour or two to complete.
  15. I don't have an answer. I have never seen this error. I'm signing on to see if anyone else knows what is going on.
