hhmmm yes, seems a hierarchal pool was inadvertently/unintentionally created. i have no idea of your skill level so if you're not comfortable with any of the below... you should go to https://stablebit.com/Contact and open a ticket. in any event removing drives/pools from DrivePool in the DrivePool GUI should NEVER delete your files/data on the underlying physical drives, as any 'pooled drive' is just a virtual placeholder anyway. if you haven't already, enable 'show hidden files and folders.' then (not knowing what your balancing/duplication settings are), under 'Manage Pool ^ > Balancing...' ensure 'Do not balance automatically' IS checked, and 'Allow balancing plug-ins to force etc. etc...' IS NOT checked for BOTH pools. SAVE. we don't want DP to try to run a balance pass while resolving this. maybe take a SS of the settings on DrivePool (Y:) before changing them. so DrivePool (E:) is showing all data to be 'Other' and DrivePool (Y:) appears to be duplicated (x2). i say this based on the shade of blue; the 2nd SS is cut off before it shows a green 'x2' thingy (if it's even there), and drives Q & R are showing unconventional total space available numbers. the important thing here is that DP (E:) is showing all data as 'Other.' under the DrivePool (E:) GUI it's just as simple as clicking the -Remove link for DP (Y:) and then Remove on the confirmation box. the 3 checkable options can be ignored because DrivePool (E:) has no actual 'pooled' data in the pool and those are mostly evacuation options for StableBit Scanner anyway. once that's done DrivePool (E:) should just poof disappear as Y: was the only 'disk' in it, and the GUI should automatically switch back to DrivePool (Y:). at this point, i would STOP the StableBit DrivePool service using Run > services.msc (the DP GUI will disappear), then check the underlying drives in DrivePool (Y:) (drives P, Q, & R in File Explorer) for maybe an additional PoolPart.XXXXXXXX folder that is EMPTY and delete it (careful don't delete the full hidden PoolPart folders that contain data on the Y: pool). then restart the DP service and go to 'Manage Pool^ > Balancing...' and reset any changed settings back the way you had/like them. SAVE. if a remeasure doesn't start immediately do Manage Pool^ > Re-measure > Re-measure. i run a pool of 6 spinners with no duplication. this is OK for me because i am OCD about having backups. i have many USB enclosures and have played around some with duplication and hierarchal pools with spare/old hdds and ssds in the past and your issue seems an easy quick fix. i can't remember whether DP will automatically delete old PoolPart folders from removed hierarchal pools or just make them 'unhidden.' perhaps @Shane or @Christopher (Drashna) will add more. Cheers

FWIW... current version WizTree 4.13 has support for DrivePool. https://diskanalyzer.com/download scroll down to changelog v4.13 to see all new changes. works great. 193,000 files in my pool and it took about 20secs to show them all.

hi. in windows/file explorer enable 'show hidden files and folders.' then go to: https://wiki.covecube.com/Main_Page and bookmark for future reference. from this page on the left side click StableBit DrivePool > 2.x Advanced Settings. https://wiki.covecube.com/StableBit_DrivePool_2.x_Advanced_Settings if you are using BitLocker to encrypt your drives you will NOT want to do this, and will just have to live with the drive LEDs flashing and disc pings i assume. i don't use it so i don't know much about it. the given example on this page just happens to be the exact .json setting you need to change to stop DP from pinging your discs every ~5secs. set "BitLocker_PoolPartUnlockDetect" override value from null to false as shown. if StableBit CloudDrive is also installed you will need to change the same setting for it also. opening either of these json files, it just happens to be the very top entry on the file. you may need to give your user account 'full control' on the 'security' tab (right click the json > properties > security) in order to save the changes. this worked immediately for me, no reboot necessary. YMMV... good luck

yes. 1x means no dupes. 1 complete file only. 2x = 2 dupes. 2 identical complete files. 3x = 3 etc. all (each) on separate physical drives (assuming enough drives are present). DrivePool will NEVER split files. it may/will split folders across different underlying drives to achieve whatever balancing ratio you have set up using the various available plug-ins. the 'drive usage limiter' plugin (called 'file placement limiter' in the manual, maybe it was renamed) will allow you to choose which discs hold which types (duplicated/unduplicated or both). 'file placement rules' ensure certain type files go to certain discs/directories. parity is a long requested feature for DrivePool. as a long time reader of these forums i can say with some confidence it will NOT be included as an option. many many users report success using SnapRAID for parity. i don't use it so i have no guidance there. my pool has 6 spinners and no duplication since i have backups and backups of some backups lol so i would suggest RTFMs and the forums, even running a non-production test pool should be useful. here are some links to get you started... https://stablebit.com/Support/DrivePool/2.X/Manual https://stablebit.com/Support/DrivePool/2.X/Manual?Section=File Protection https://wiki.covecube.com/StableBit_DrivePool_Knowledge_base

aaahhh the dreaded 'not knowing torrents were involved' syndrome i have read conflicting advice here in these forums as to whether torrenting is a good idea with DrivePool. for simplicity's sake i keep all that separate from DP. for torrents i finally settled on 2x4TB drives in Raid1 on an Oyen Mobius Pro 2C on a separate USB adapter card from the card where DrivePool lives in a Syba 8 Bay. i only continuously seed full seasons of some TV shows and some hard to find movies, so i have plenty of space there to work with. ok so snapraid has been paused while you work this out- good idea for sure. i assume you've paused torrenting and downloading as well, if those clients d/l to the pool. the 'math' involved in keeping a large pool balanced is a lot to say the least, even more so if you have real-time duplication enabled and/or a steady trickle or stream of torrents and downloads are present. regardless of either, DP now has a huge task to spread data across 25.5 TB of new space, while then having to calculate which files/folders will be moved from the already present disks to meet the DSE plugin's percentage requirement. so in this case i highly doubt you're gonna see drives running at full speed until the rebalance is complete. maybe the existing pooled drives haven't been defragged in a while? if you are torrenting to the pool there is a likelihood of major fragmentation there so... something to consider. maybe @christopher or @shane will have more pertinent/better explained info. if so you will want to have posted details of your DP settings about duplication, performance, etc.

yes. my point exactly. and S1D4 shows 7.95TB capacity. could these drives actually be partitions on drives larger than 8TB (file explorer will report an 8TB drive as 7.27TB and DP will show the same drive as 7.28TB in the GUI)? it is certainly a possibility. but not likely. which is why i suggested a reset of DP's settings. of course i could be totally wrong here, wouldn't surprise me a bit lol

hi. follow this link and bookmark it if you haven't already. https://wiki.covecube.com/StableBit_DrivePool_Knowledge_base you mentioned that you've been using DrivePool for a few years. so you must have a good idea of what your DP settings are (under the pie chart in the GUI, 'Manage Pool ^ > Balancing...' and the 3 tabs there within). before you do anything, i recommend you take screenshots of all your settings, plug-in settings, EVERYTHING under all 3 tabs that is pertinent. yes, this is a PITA, but once it's done, you're golden right? no need to do it again unless you discover that some of your settings are sub-optimal and need to be altered. if you are using the 'Drive Usage Limiter' plugin, have all the correct checkboxes been checked? from your screenshot- S1D2, S1D4, S2D2, and S2D3 seem to be reporting erroneous info. i.e. how can a 7.28TB capacity drive have 7.46TB of data on it and still have 260GB left to fill? this craziness may all be due to DP's internal math. i would: follow Knowledge Base Q2299585B and reset DP's settings. maybe even Q2150495 as well. this is where your screenshots will help. if you implement Q2299585B i would at the same time, in the same mouse movements after the reset is done, IMMEDIATELY click the Manage Pool ^ and under the first tab put a nipple on the titty 'Do not balance automatically' and UNCHECK 'Allow balancing plug-ins to force immediate balancing (regardless of the automatic balancing settings).' click SAVE. THEN: refer to your screenshots and set your settings back up the way you had them. then alter any settings on the first tab. SAVE. i hope any of this is helpful. none of what i have said has much if anything to do with the 'speed' issue you brought up initially. left to its own devices DP is just slow and steady. i would get happy with my settings then let DP just do its thing in the background.

and 104F = 40C, so it is likely the same crappy firmware on yours that was on the 2 that i returned. i guess they can get away with it as 'most' users will just buy it, install it, and not really monitor it. so these errors and notifications are never seen by joe average user who runs games from it and is suprised when it fails suddenly (check out all the 1 star reviews on the amazon page lol). i have 4 SSDs. all are WD. 1x Red SN700 500GB NVME boot drive. 2x Red 1TB 2.5" and 1x Blue 2TB M.2. they all show up fine SMARTwise in Scanner and HDSentinel. i guess this makes me a WD 'fangirl,' but really that's just how it worked out. before i tried the Silicon Power drives, i tried both the LEVEN JS600 SSD 2TB and the fanxiang S101 2TB SSD. all 3 were underwhelming performance-wise compared to the WDs. gotta love amazon's 30 day return policy iceman1337 is correct and he's echoing christopher (drashna). SMART on SSDs is all over the place as manufacturers just make it up as they go. your SP might last for years ignoring whatever errors it shows. but i wouldn't trust it for mission critical data. just my .02 cents...

in Scanner go to settings with the wrench icon > advanced settings and troubleshooting and on the first tab is where to bu/restore its settings. it will create a zip file containing many json files and want to put it in 'documents' by default so just back it up elsewhere. note that i have never actually restored Scanner using this procedure but it seems easy enough. as for DP, any duplication settings are stored in metadata on the pooled drives poolpart folders and the pool will be automagically detected by DP when installed on the new machine and all original pooled drives from the old machine are reattached. balancing settings are not saved anywhere that i know of. i imagine this is because of possible hardware changes. i went old school and made screenshots of all my balancer settings in the UI and i back them up in a folder with a text file containing snippets C/P from forum posts for future reference. if you have edited DrivePool or CloudDrive json files then you know you can find and copy them from C:\ProgramData\StableBit DrivePool\Service and C:\ProgramData\StableBit CloudDrive\Service. perhaps grab a copy of C:\ProgramData\StableBit CloudDrive\ProviderSettings.json as well if you have a CloudDrive that you want to keep easy. i don't use CD so i'm not sure about that last one lol. and you may need to reset permissions on the pool as well. https://wiki.covecube.com/StableBit_DrivePool_Q5510455 all that said, i haven't needed to restore any StableBit software yet, but i feel like i'm prepared enough should i someday need to. hopefully someone more knowledgeable will chime in here and add info if needed. hope this helps... good luck

welcome to the world of cheap SSDs. a few months ago i bought 2x2TB Silicon Power 2.5" SSDs from amazon. hooked them both up to system SATA bus. one drive reported 1863GB and the other 1907GB. diskpart was ineffectual. both were locked at SMART temp 40C (idle or high I/O). writing to them from my WD Red NVMe was ~300MB/s so much less than advertised. there is a downloadable SP monitoring tool similar to the WD dashboard. i did not notice an option to upgrade firmware when i ran it. so after a few days of this i returned them to amazon easy peasy. aside from a much needed firmware update from SP, i doubt scanner can do much other than report whatever the drive is feeding it. the drive itself may be perfectly fine and ignoring the warning is probably safe for now. i myself cannot abide that type of discrepancy staring me in the face. YMMV, but if it were me i'd return it and get a WD, which is what i actually did.

i notice the red X error message says 'format must be valid.' check and make sure you include the { and } before and after the actual numbers/letters

i do not believe any 'solution' is necessary here, as DP will show up in Disk Management as 2047.97GB per local pool. i.e i made a new 'test' pool from 2 500GB hdds for a total size of 1TB (931GB available) and Disk Management reports that pooled drive as 2047.97GB, same as my primary pool drive which is comprised of 4x 8TB and 1x 4TB hdds. in Disk Management, 'right-click > properties' on any pool partition showing 2047.97GB will give you the pie-chart dialogue showing the total/used/free size of the combined underlying disks. so... the (any?) pool drive that is shown in Disk Management is seemingly just a kernel/filesystem 'place holder' where DP can dream big dreams but chdsk won't work as there is no actual 'disk' for it to check. as for the pool not showing in Scanner, i think it's by design that it's not there. the disks comprising the pool are all there (at least for me, so i'll assume for you as well), so unnecessary overhead is avoided. it would probably throw errors in much the same way as trying to run chkdsk does, as it's a 'virtual' 2047.97GB 'place holder' and not an actual physical disk. pooled drives will show in the GUI for DrivePool as they can then be added to hierarchal pools. if i had to guess, i'd say Stablebit DrivePool/Scanner are working fine for you in ALL respects (knock on wood ) hope this helps. CHEERS

I haven't earned a gold shield yet lol... Scanner is almost through with all my disks on its 2nd monthly pass. But HDSentinel gave me a scare recently. I have 2 x Mobius Pro 2C enclosures both set at RAID 1. In one of them the primary (top) disk threw a Threshold 165 for SMART #3 'spin up time.' 0% health failure predicted. I just let it run as the drive LED remained blue, while I rummaged thru warranty paperwork and made screenshots. Day and a half later the error just disappeared. Back to 100% health Threshold 24 just like the 5 other identical disks i have (HUH728080ALE601). Computer had been up at least 4 days before error occurred, and was days after error cleared before a reboot. The drive survived a few reboots since then and recently passed its first StableBit Scanner run (it is not part of my pool and had excluded it from my testing during trial period). During Scanner's surface test only the primary disk was read from/tested anyway so there's that 'lucky' quirk. I understand that Scanner works with just what the controller feeds it. HDSentinel sees both physical disks in the array so I could test the secondary disk with it, but I've been wanting to break those arrays for a while and I now have a good excuse. I will add it to DrivePool and mark it duplicated only. So yeah, spooky deus ex machina type stuff goin' on lol... good to know I'm not the only one.
