My motherboard died, and one of my hard drives had errors checkdisk couldn't fix, so I purchased new motherboard, processor, RAM, some case fans and 1 HDD. After the rebuild the drive letters had changed. I reset the paths in qBittorrent settings to the new drive letters. The data is on one of the drives that didn't fail. The torrents were copied from the dying drive to the new drive and look OK. I installed v4.5.4.
qBit shows Missing Files. After forcing recheck it shows Checking resume data and 0% progress. After a long wait it shows Errored: Incorrect function. If I reopen the torrent file it says torrent is already present. One of the 781 torrents now shows completed and seeding, but I can't figure out why. If I right-click on an individual torrent then click on torrent options it shows the old drive letter but changing it to the new letter doesn't seem to help. Suggestions will be appreciated.
UPDATE: I used disk manager to change the drive letters of the HDDs where the torrent files and downloaded files were stored back to what they used to be, and that fixed the problems.
