Reinstalling windows on C, need to keep files on "D"

[ijuro]

Hello, i want to reinstall windows which is currently on my C drive and my files are on D drive. I created logical partition "R" backup, where i want to put some my files from D drive, then format C and D drive, create new C 100GB partition and remaining space will be on D drive. But will my files on R logical partition stay there ?

If u're not formatting or deleting R partition all will be there after reinstalling.
Cheers

Thanks for your respond but i have one more question. When i copying or moving files to R, that transfer is so slow that it takes 5 minutes to copy 1 GB file. It starts at 70MB/s but suddenly after 3 seconds transfer speed drops to 7-11MB/s .

What make and model are the drives? What sata ports are they plugged into?

It's transfer between partitions on 1 drive which is Seagate 1TB, 64MB, SATAIII, ST1000DX001 SSHD and i have it conected to first sata port. But this also happens when i transfer files between internal and external hdd or when i plug second hdd to sata port 2. Always same situation and i need to backup files which are 15 gb and it takes too much time (4 hours to transfer 15 gb)

So are C:. D: and R: all on the one drive? A 1TB SSHD? Is it plugged into a sataIII port? How much ram have you got?

And you have other drives in the PC as well?

Right now i have only one 1TB drive in pc and all partitions are on this drive. Yes it's in sataIII port . So i don't have any other drive conected right now. I have 8 GB ram.

Fragmented data can increase transfer times, as it takes longer for the read/write heads to find the scattered pieces of related data.

The SSHD should work OK - http://hdd.userbenchmark.com/Seagate-Desktop-SSHD-1TB/Rating/1784

It runs at 7200 rpm.

Is it any better with data transfer speeds to and from another drive?

I have discovered that this is happening only when i transfer big file. When i transfer folder which is 20 GB large and contains files which are about 300mb to 1,5 GB transfer is fast. But when i try to move file which is 15 GB large it get stuck on 7 MB/S after copying 1-2 GB. And it's same when i copy/move files from or to drive. For example i tried copy something to and from external hdd to this seagate hdd and when file is large it will be slow. Also when i conect my other drive which is some toshiba hdd from notebook the transfer from external hdd is slow. Right now i'm installing new windows and wonder if this problem will be solved.

Maybe then its to do with only having 8gb cache. Any file below that is OK. But above that it has to be broken up and re-assembled.
