Hi and hope everyone had a good weekend (and thanksgiving in the US). I have had stablebit drivepool and scanner for the past 3 plus years. It has worked great. I have a mirrored setup of two 4TB drives in my pool. This is housed in a windows server (essentials 2016) that backs my home client PCs nightly and also has server folders for the family. The server is also backed up into an external 8TB drive every day. I am planning on replacing the internal 2 4TB with 2 8TB drives as I am almost out of space. I do not however have an available spot inside the computer to add one or two more drives during the upgrade. So I was wondering what my best (fastest or safest if they differ) options for migration were? 1. Remove one of the two HDDs probably via the DP UI ( i presume i would need to force it to cancel duplication when that happens?) and which of the two should I start first with, given that I believe that one of them tends to have slightly less space maybe from the VSS. Then I pop the first new 8TB drive in its spot, add it via DP, and wait for the over 3TB data to be copied over. Then repeat with the second drive? Or would this be too many writes. A to B and then back to A 2. Switch of the PC, pull one drive out and clone it to the 8TB drive and then do the same for the other. When i put the two new 8TB cloned drives back will DP recognize that these are the same content as the previous pool except for the size? Or does it use serial numbers of the old drives and would that be an issue. 3. Connect one or both of the new 8TB drives to the PC via an external USB enclosure such as the one I have: Unitek 2 drive unitek enclosure Then ask DP to add them to the same pool and do its magic and move the files to the two new drives? This may take a while given in my experience the external enclosures are slow even if they claim to be USB 3.0. For options 1 and 2, I presume I should stop all actions in the server like client back up and server backup before I start I presume? Thank you for your time. Best AK

All, I have a 16TB encrypted drive on Google. At sometime, over the past week, folders have gotten corrupted and are no longer accessible to me. Some remain viewable/explorable. I have attempted to run chkdsk to hopefully repair whatever issue there might be, but the process hangs at the same point each time I attempt. Are there any other suggestions to try and regain access to the data and folder structure? (Although the data is replaceable, it does amount to a not-insignificant time-sink for me to recover from other places.) Thanks for any help!
