Had this strange issue start yesterday on my HP Microserver. Now it is very old and slow and the drives are oldish too, but particularly, a 1tb drive yesterday started to go incredibly slow when I read photo files off it, either loading large thumbnails in explorer, or in Windows Photo viewer, or in a photo editing program called DarkTable, and i'm reading these files on my PC, over the network. The disk goes to 100% load and 100% active time, but read and write basically stay at 0, and fluctuates up to small 30-50kbps, with occasional bigger blasts and eventually, the thumbs will load, or one image will load in full, but it takes minutes. I can see each image loading via Resource Monitor. It is really odd, even earlier in the day it was fine, and then it went slow, around about the time I was transferring files. Only thing I can slightly remember happening at the same time was I accidently ctrl+z'd a folder delete or move, so I cancelled it, so not sure if that has got it confused.

I cleared the thumb DB on both computers, which no improvement.



What's strange is, I backed up the whole photos folder to another drive, and that completed fine, 20-30mbps.

If I leave the photos alone and play music, stored on the same drive, it loads and plays fine over the network.


So i'm not sure if the drive is failing or when loading photos RAW + XML's and jpg, something is making it lock up.


I done a very quick test of loading the photos on my computer over the network on the drive I copies the photos to, and that seemed ok, but I need to test more, as I only had a couple of mins before work.


Any thoughts would be great. Thanks
 
How big was the Folder that was deleted that you then accidentally undid? If it's large enough (and had lots of small(er) files) and it was putting it all back, it might have just been restoring whilst you were working and thus you got the weird access and transfer times.
 
Yeah that's what I thought, and I was actually doing another copy at the same time.

Somewhere between a 1gb-4gb, full of 10-20mb files and some smaller xmls, so not massive, and its had plenty of time since to sort its life out :D.
