  1. Yep, I know but the weird thing is that the other data was actually data that was duplicated. I guess it was leftovers from all the balancing / moving around data, so I ended with the same data thrice. In any case, all taken care of
  2. Hi again Christopher. Thanks for the explanation about dedup! I think I will refrain for using it on the drives that are linked to the pool. I was able finally to remove the drive, took a while and had to disable NTFS compression on all the files. The only strange thing is that there were some leftover files marked as 'Other'. I compared them with one of the healthy drives and all of them were there, don't know why they were not removed. Now I am formatting the drive and ready to send it for RMA. Thanks!
  3. Thanks Christopher! Much appreciated, I will disable NTFS compression (also to check what savings I was getting). I upgraded the DrivePool version with the provided Beta and the disk removal is progressing. I see some nice visualization bits added so thanks you and Alex for the hard work! I will report back as soon as the disk is out, and talking about dedup, I guess enabling Windows Server Dedup on the DrivePool kinda defeats the purpose of data duplication, right? Is this something even supported / recommended? I saw some posts regarding this but no so sure what to get out of them. I guess that deduplicating the files will incur in data loss if one of the drives in the pool fails, plus the fact that the drive is not even recognized if you plug it into a host which does not have the deduplication feature enabled.
  4. Generally not enable it ever, or just not with DrivePool? I think I will stay away from it anyway due to the recent events, but could you please elaborate a bit (if you don't mind) on the possible issues that might happen with NTFS compression? I use it regularly on non-pooled drives and never had an issue so far (fingers-crossed!) Force removal btw didn't work ,so I will upgrade as soon as the current balancing task completes. Thanks for the super-quick answer btw!
  5. Ok, just checked that enabling NTFS compression does not change the md5sum of the file, so I am not so sure anymore if it has something to do or not I will wait for the rebalancer to finish to see if the files go away from the damaged drive since I cannot remove it (Access is Denied). Is there a new version I can try with? Logs that I might need to collect?
  6. Hello everyone! Another happy user of Drivepool with a question regarding NTFS compression and file evacuation. A few days ago I started having reallocated sectors counters on one drive. Stablebit scanner ordered drivepool to evacuate all the files, but there was not enough space so some of them remained. I bought another drive, which I added to the pool, and tried to remove the existing one, getting an "Access is Denied" error. Afterwards, I tried to force evacuation of files from the damaged drive using the appropriate option in the Stablebit scanner. This triggered a rebalance operation which was going very well, but then I notice several hundreds of GB marked as "Other" not being moved. Then it stroked to me that the new drive has some files without NTFS compression, whereas the old drives in the pool did have. I think somehow since the checksums are not the same for compressed and uncompressed files this is somehow confusing the scanner. What I did so far (for consistency at least, hope this doesn't make things worse!!!) is to disable compression from all the folders I had it enabled (from the old drives, including the faulty one) and wait for the rebalance to complete. Is this the right approach? Is this also expected to happen when using NTFS compression? In drivepool is actually not worth the hassle to have it enabled? (I was getting not fantastic savings, but hey! every little helps, and wasn't noticing perf. degradation). Hope the post somehow makes sense and also hope my data is not compromised for taking the wrong steps! Thanks! DrivePool version: Beta Scanner: OS: Windows 2016 Attached DrivePool screenshot as well
