An indication of lots of disk damage? what gives The TR4UT-B is listed as being USB 2.0/esata, TR4UT+B is listed as USB 3.0/esata, to answer your question, yeah, 36 hours is a long time for one 2TB drive on USB 3.0, for USB 2.0 that might be correct. Are the drives over heating in the enclosure? Scanner will throttle the performance back if your hitting the max temp setting, I'm not familiar with this enclosure, but if you have a manual fan control kick it up to full speed, when scanner is running. Also, if your accessing those disks for other requirements, scanner will stop until there's little to no traffic on the controller and then restart Quote Link to comment Share on other sites More sharing options...
0 jhw Posted September 25, 2013 Author Share Posted September 25, 2013 No overheating, and server is not on any other scheduled tasks. Internal SATA drives scanned (7 HDDS) in less than an hour, but scanning USB connected drives is taking literally forever... Quote Link to comment Share on other sites More sharing options...
0 Christopher (Drashna) Posted September 25, 2013 Share Posted September 25, 2013 Can you verify that there is no other activity? Does the "scan" section say that it's throttled? Also, you can check the performance by right click on the column header, and select "performance". That will list the activity speed of all the drives in Scanner. Also, do you have a lot of smaller files on the drives? Worst case here, try restarting the Scanner service, or reboot the system. Quote Link to comment Share on other sites More sharing options...
0 dbailey75 Posted September 26, 2013 Share Posted September 26, 2013 also confirm the model number of your enclosure, the model you provided is USB 2, that could be the issue if it is USB 2. Quote Link to comment Share on other sites More sharing options...
0 jhw Posted September 26, 2013 Author Share Posted September 26, 2013 At the moment I think the enclosure is set up/connected USB 2. Sorry - but I will be out of town and away from the system for at least a couple weeks: I can remote in via my PD connected to the server, so will at least hope to get all the current drives "checked" over that period of time, then be in a position to restart server, check BIOS setting to be sure I really have USB3 enabled, and start again from there. This all started (i.e.everybody was playing nice) until about 6 weeks ago when I had an old (>3-4 years) 1.5 TB drive go bad, overheat, and die. I've replaced it and actually managed to migrate all the data from the remaining 3 drives in that enclosure, however have had recurring problems since. And yes, some of my data is photos (jpeg and a few mpg) but the bulk of data stored is videos (iso) files that are big and space-hungry. Oh, if only HP still made a MediaSmart server which was soooo reliable - but it's motherboard dies (after 7-8 years) and so I built my own server. Woe is me. I'll reactivate this message chain when I can get back hands on. In the mean-time thanks for all your suggestions and directions! Quote Link to comment Share on other sites More sharing options...
0 Christopher (Drashna) Posted September 26, 2013 Share Posted September 26, 2013 They do sort of still make it. Check out the HP MicroServers (the N40L or the N54L, IIRC). They don't have WHS built in, but it's a very similar form factor and design. Quote Link to comment Share on other sites More sharing options...
0 Alex Posted September 29, 2013 Share Posted September 29, 2013 Scanner is taking > 36 hours to scan a single disk. Is this normative? An indication of lots of disk damage? what gives As the developer I should mention something important here. The disk scan speed is really not our top priority. While we have a very fast surface scanner (as is advertised in the Features tab), it is not always running at full speed. Because we're running in a multitasking environment, our top priority is not to interfere with other applications using the disk. You can override this behavior under the Throttling tab in Scanner Settings and have faster scan times at the expense of system slowdown, but I don't recommend it. In short, the StableBit Scanner is tuned towards not interfering with any existing disk access more than getting the absolute fastest scan time possible.
