I'm running Windows 10 Enterprise LTSC (C drive). I had 3 cloud drives on Google set up, E, F, G. 16 TB each and each half full. NTFS, default settings. 100gb cache for each on a 1TB SSD exclusively used for cache (D). A week ago there was an unexpected shut down so all three drives started to re-upload their cache. Except the "to upload" for E just kept growing until at around 670 the D drive was completely full. This was despite the fact that my upload speed appeared to be maxed out for days. F and G seemed fine after cache re-upload with no activity. E, however, was regularly downloading data despite no reason for it as no other applications to my knowledge were accessing it. I unchecked indexing options for each drive in Windows explorer. Eventually I destroy E drive in the hope that will solve the problem. Now F is displaying the same symptoms as E. Any ideas what is going wrong?
