Reprojecting raster taking hours, not sure if it's even working

Hello,

I'm trying to reproject a couple single band landsat images to use in my analysis. I've had the first reprojection running for almost 2 hours and it's at 0% progress. I reprojected a DEM covering the same extent and it took 10-15 minutes. Is there any way to see if it's even working? No error messages, but no progress either. I have parallel processing factor at 100%. Any help would be appreciated.

what parameters are you using?

nearest neighbor? did you specify and output cell size? did you use a snap raster to align to your other data?

lots can affect the time but 2 hours seems a bit off

I used nearest neighbor, specified the output cell size as the input size for the same raster, did not use a snap raster. I left it running all night but when I woke up this morning it had crashed. I'm trying it again as we speak but in model builder so I can see more details, but it's been running for 10 minutes and there's been no progress once again. Here's what I see in the model builder dialog box:

I figured out the problem: It was cell size. I was defining the cell size by using the input raster and it was using degrees, so the cell size was extremely small. I thought it would convert those dimensions to meters, but as soon as I selected Preserve Resolution, it changed them to meters and the projection took no time at all.

filenames and paths with space aren't great, and are you projecting from utm to geographic? or the reverse
