Perplexing hard drive transfer rate issue ?!

ferret face · 6 Aug 2009 at 11:41

Hi

I have a weird problem that maybe some one can shed some light on?

I have a Samsung F1 1tb drive and sometimes when I try and transfer large files to it such as DVDs etc it will suddenly slow down the transfer rate.

For example, I can sometimes copy over a DVD file in iso format in about 4 minutes or so. Then other times the time will slowly creep up and up to say 10 mins, then up to 180 mins etc.

I then have to reboot the pc and will then be able to transfer at normal speeds again for a while until it starts creeping up again.

Does anyone know why this is happening?

Cheers Ferret

I defragged it the other day so its not fragmented, I'll check event viewer when I get in tonight to look for errors.

Cheers

I am cutting and pasting large iso files and mkv's from one drive to another, there are no cd/dvds involved.

The Samsung drive has the firmware it came with from Overclockers.

Yes both drives have been defragged this week.

Seems weird that it only happens with one drive though?

If it was antivirus, indexing or chipset drivers etc then wouldnt it happen with all drives?

mmmm... I couldn't see any processes eating up cpu but I just noticed when it slows down its going into PIO mode and I also get an error in event viewer

Event ID 51
There was an error detected on ......hardisk1/d during a paging operation.

This only happens when transferring large files, not sure why

Any ideas?

Ok, I've sorted it out. I changed the cable! Must have been faulty

Cheers
