Losing space on my C:-drive without downloading to it!

[Flaringo]

Hi, yesterday I noticed one of my disks were constantly making noises, so I thought they might be low on space. I checked my C: drive (my system drive, nothing but windows and applications there, maybe some cached stuff too), it had about 150 megs left. I ran CCleaner, but that only cleared up about 50 megabytes, so I just waited a while, checked again and to my surprise I was now at 500 megs, checked a minute later and another 300 megs were free, shortly after I was up to about 1,3gigs, which is how much I had free from the start. My drive was still working loudly, so I had to restart my PC.

The drive has been quiet until just now when I started µtorrent about 15 minutes ago. It took a little while (maybe 5 minutes) before my c: drive started making noises again, and like last time, losing space, then getting it back again shortly after.

I was downloading and uploading at the time, but that was to and from my E: drive, so it shouldn't affect my C: drive, at least not in that way.

So do anyone have any ideas what this might be and how to fix it? Because to me, it's a mystery.

Need more info...

1. Where is utorrent installed?

i presume you left it on default C:\program files\utorrent

2. Did you configure utorrent to "Reserve all the space at once" or "incremental" ?

it seems like you have it on "incremental"

3. Where is your utorrent Download directory?

my guess you have it on C:

4. Where is your utorrent Completed directory?

seems like you put it on E:

Hard drives making "noise" is never good. Unless you're talking about old models where you can tell when it spins up and the read/write heads seek across the disk. As far as space being used and then freed.. what other programs are you using? If you're not using uT why did you post it here, heh.

AllGamer:

1. Default, yes.

2. I'm not sure, where do I check this?

3. Should be on E: -- if not, where could I set it?

4: Yes, on E:

jewelishheaven: Disks are pretty new, when I say noises I mean normal working disk noises, just alot of it.

Other programs? Well there's alot of them, but they havent interfered before, so I doubt they're the cause!

AllGamer is referring to the "pre-allocate" option under Ctrl-P -> Downloads .. Also if the drive is NTFS check for Ctrl-P -> Advanced diskio.sparse_files . . . That will tell Windows to "allocate" the space (i.e. show it as 1 Gb file) but not actually USE IT (shown in properties (size of file vs actual size on disk)).. until you download it
