[SOLVED] Secondary HDD transfer rate drop

post #1 of 11
Thread Starter 
Hello,

I recently changed my secondary 160GB Hitachi HDD to a 320GB Fujitsu for more storage and randomly transfer rates drop to almost zero. Primary storage is an Intel 520 60GB SSD, moving a video file for example, transfer speed is 118 MB/s, moving more then 1 file at the same time at around 80% completion speed drops to zero and hangs there for a long time. Drive was taken out and works great in another machine. The laptop is a DV9815 with Windows 10. I know no driver support but the Hitachi HDD was working flawlessly. OS is fresh install. I've tried to screenshot a HDTune benchmark but looks like there are some serious problems because I'm not able to save anything on any of the drives.
I should mention, I've updated the standard IDE driver with the standard AHCI driver right after installing Windows.

EDIT:

I forgot, waking up from hibernation the laptop does not boot with black screen message: boot device not found

Well when using a Mechanical drive and you are writing something in a spot, you can't really ask it to write something else at the same time to another spot. It hasn't finished the process and now it's kinda confused where to stop the one file and start the new one really. Maybe the cache size is way different on the other one you put in there and it's not just a bigger drive, but a way slower or cheaper drive? I know what you mean tho when trying to write another file before the other has finished. It usually won't do that anymore because that very reason. It's best to wait til the file finishes or to just move both at the same time, meaning you choose both files, choose where you want them and then start the move / transfer at the same time so the drive knows what it's doing before hand. I have moved to only using SSD's tho now and that's a thing of the past for me really. I just can't stand mechanical drives anymore, even if it's just for storage purpose.

I put a 512gb Samsung 950 Pro in my new laptop and took the 1tb mechanical out. I want more storage space tho for the 2.5" drive bay, but I'm waiting until I can buy a 1tb Samsung 850 Evo SSD or bigger to put my storage drive in. I really only want to be using ssd's over using a mechanical at all. I am tempted to put a 7200rpm 1tb mechanical drive in there tho since that's what came stock in my laptop and it's just sitting there on my shelf doing nothing LOL.

Maybe I did not express my self clearly, moving x from A to B no problem, good transfer rate. Later moving xyz from A to B random speed drops and hangs. Im not trying to do multiple coping, If I ever did I always pause the file that I do not need asap. Clearly there is some problem with my device because taking out the HDD and connecting it to another device works flawlessly.

About mechanical drives, in a laptop yeah. Even if you upgrade to SSD for less heat was already worth it, not mentioning faster speeds.

Ah, I see. Well that's strange then. Hmm. I'm not sure on that.

So what if later you just wanted to move x or y or z back from B to A, instead of xyz from B to A, does it still drop the rate like you say?

Reading it is worse. Moving anything from B to A drops below 1 MB/s and there is more. Anything that is trying to access the secondary drive immediately enters not responding state. I think I'll do a fresh OS install, I might have messed up the drivers earlier.

When you put that drive in as your secondary drive to use, did you do a fresh format on it even if it showed up as being usable? I mean going in through " Computer Management / Storage / Disk Management " , then delete volume of that secondary drive, then create new simple volume and assign the letter you want to use for that drive ( as in S: for Storage , or D: for Data ) or name it?? I always do that type of format and not just go to "This Pc" and right click the drive and do quick format. The way I do it is still a quick format and all, but I've never had a problem when doing it that way. It's worth a try before having to install a fresh OS again.

That's why I started this thread, all out of ideas. Will reinstall OS later.

In DV9815



Same drive in another device



Any ideas what could cause this?
Could be the drive stuck in PIO mode? HDTune says it's UDMA 5.
