Download a file to a particular drive

I usually d/l on my data disk, drive H. Recently, for some reason I cannot now. I using Utorrent. When I do, an error shows up: "Error: The system cannot find the path specified (WriteToDisk)." Excuse me??? I have enough space on my drive. I am forced to use another drive, drive G; but this drive is skating on thin ice as far as space is concerned.  The drives I wanted to d/led the file is 2.3Gbs; the space on the drive is 14.5Gbs. Do you think Microsoft update in May could have caused it? On the same token wouldn't it affected drive C, which it didn't? What I did was d/l the file to Drive F (USB drive) and when done, transferred the file to drive H. In the process, a window appeared and told me I have to have special permission to transfer the file. Should I continue? I chose yes and it did. I went to my files and looked up the properties of the folder download in drive H. In the permission, every check box is checked expect FULL CONTROL and the property window is greyed out. I can't do anything to the window!!! Very frustrating... :-(  I am the administrator.

UPDATE:   I used: drive H alone and it started downloading. Any other folder won't.  NOTE: In drive H, there are 4 subdirectories. The last one was just administrated, the video file. In that folder, I looked into the properties. In the subtab, security, FULL CONTROL is allowed. It is still in relief though. The other 3 subdirectories DOES NOT allow FULL CONTROL, also in relief. Also, in 3 of the previous subdirectories of drive H, I checked in the Permission category and I cannot add nor remove any permission status; but the last subdirectory I can. Would someone please tell me what am I doing wrong???
