Windows 7: Transfering large files make W7 Slow Down to a Crawl?

Transfering large files make W7 Slow Down to a Crawl?

My main HDD is comfigured into two partitions, C: for W7 and D: for data/downloads/etc. Whenever I copying a large file from Partition D: to Partition C: and vise versa, the transfer slows down to a crawl and the HDD activity light on my case stops blinking.

Anyone else have an issue with W7 slowing down to a crawl when transferring a large file from one partition to another partition?

Doomie, does this happen with any other files? Or just that one file?

It happens with other files too but here is the odd thing. I tried another large file and the transfer never stopped.

Welcome to the Se7enforums! doomie22

Seeing slowdowns when transferring large files between two partitions or even two separate drives is not limited to 7 alone. I've been seeing that over the last several years between XP and Vista as well working on video projects or copying a large volume of files stored in a collection of sub folders under one main folder being backed up.

That will tend to place a load on cpu time where things will start to crawl if you are running programs at the same time as the transfers are taking place. Yet moving files and folders between partitions on the same drive is instantaneous most of the time.

If it is just that file, then I would recommend moving it another way, or moving it in parts.

That is a logical function. The files themselves do not move, their "addresses" are modified.

Thanks for the welcome!

Could it be maybe that there are errors on the partition and running scandisk might help? I know that the files are located on a partition that is heavily fragmented. Would defragging the partition help?

This is the first time I've encountered this issue. I never had this issue with XP either.

I am using the W7 default HDD controller drivers and I was wondering if using the HDD controller drivers that came with my motherboard would help?

I was starting to like W7 and now I'm not too sure.

Is Media Sharing enabled on the target machine? If the target folder is being indexed during the transfer, you would get this slowdown.

And yes, defrag the files would be appropriate.

If you are finding a heavy level of fragmentation that would be the first step to take to see how far you can bring that down. Vista and 7 both see an improved SuperFetch over XP's PreFetch memory manager where the defrag tool is loaded at a minimum background level running quietly there keeping the fragmentation down to 0% in most cases.

With XP however a regular checkup and periodic defrag was often needed if you saw the levels climb. Any heavily fragmented files, folders, even an entire volume will slow everything to a crawl. I think you found the solution to your own problems!
