Need Tech help on plotting
I will try to explain this so when you all start to answer you will know where I am. 2 days ago I upgraded my HDD's went from 10ish TB to 25TB 1X5TB and 2X8TB all Seagate external HDD's. I run Win 10 I have the newest AIO wallet with the v1.0 XPlotter. Started to plot the 5TB first using the plotter that is apart of the AIO 12 hours later I was still at -n 60k but the writting the scoops was barely breathing it had only written 12% scoops. I stopped there reformatted the 5TB HDD and decided to manually do it. using the ADMINISTRATOR command prompted I set the script set the -id and -sn set thread at -t4 -path E:\burst\plots -mem 15G. error came up saying cannot plot to plots. ahh ok went back to the download for XPlotter by @Blago read and reread noticed i could change the path to just -path E:\plots -mem 15G. that was 2 days ago. My puter has 32G DDR4 ram 6th gen I7 4.4 Ghz GPU Nvidia Titan X 15Gig I have 6 external 3.0 usb slots and 2X 3.1 usb slotsso no way to mess up were to plug in the HDD's. Anyway still day 2 I am at 28% generating -n happen to really look at what is going on im at 2602 nonces/min instead of what was my typical 13k/min HMMMM looking at HDD: writing scoops: its clicking away but slowwwww exp. 16.96 to 16.97 takes about half of a sec. so now I am asking please tell me if i wrote the string wrong or what I don't know.
@croydan1 what I usually do is to generate first that file E:\Burst from the AIO wallet when selecting write plots. Then I close it (no actual need for it opened anymore) and set everything as you did in the RunThisAsAdmin.bat file. Keep in mind that if you click on the running console it stops/pauses, if pressed enter starts running again :) When you formatted what allocation unit size did you use? And how big are your plots?
@vExact formatted at NTFS 16K and plots are 30,720 nonces
@croydan1 use better 64KB
@croydan1 that may have been 64K brain is tired
@croydan1 and you get what speed?
@croydan1 2600 nonces /min
@croydan1 I am guessing i should stop plotting so that the \burst file is in place?
@croydan1 thats a bit slow for the specs you have. I have similar procesor and if I use my 8 threads I can get 12k/min
Also don't forget to actually right click on the bat file and run it as administrator! :)
@vExact ok np and I was just going strait to admin cmd promp but not thru the .bat file
so I will change that also. I will post wether this has helped or still the same later.
@croydan1 your drives is SMR? https://forums.burst-team.us/topic/2394/shingled-magnetic-recording-smr/25

and plotting at 14K/min the writting of the scoops is the slow part and to answer the question you asked I really don't know I do have http://www.seagate.com/www-content/datasheets/pdfs/bup-dt-hub-amerDS1894-1-1605-AMER-en_US.pdf that is the 8TB pdf and for the 5TB is http://www.seagate.com/www-content/product-content/backup-plus-fam/backup-plus-desktop-drive-v2/_shared/docs/backup-plus-desk-v3-ds1757-6-1505amer.pdf
@croydan1 Both the 8TB and 5TB drive are SMR drives i guess ... thats what i had in this external drives ...
Look in the description of the above drives, both SMR.
SMR drives are no problem in general if you just write to them in one squence, therefore i suggest you plot to a 'normal' PMR drive and copy over the optimized plots to the SMR drives.
Maybe you have a 2TB or 4TB already with existing plots? Copy them over to the SMR drives and after that plot that 'source' drive again and repeat.
I just plotted 4TB PMR drive (http://geizhals.eu/seagate-desktop-hdd-4tb-st4000dm000-a903248.html) in one optimized plotfile with xplotter ... took ~24h.
How can I tell if an external I have is an SMR drive?
Multiple ways ...
- As far as i know only seagate uses SMR drives
- visit manufacturer page and search for tech info on your external drive
- open the external case (will void warranty!) and google the drive product code
- post link to your external drive ... and somebody maybe knows
- trust me if i tell you 5TB and 8TB external usb3 drives from seagate are SMR (not sure on other capacity)
List of SMR external drives:
@socal @luxe You can also use CrystalDiskInfo to get the model number and serial number of the drive without cracking it open: http://crystalmark.info/software/CrystalDiskInfo/index-e.html
I gotta say, it's a very handy tool. By looking up the model numbers I can confirm that all my 4TB Seagate Externals have Desktop (PMR) drives in them, and all the 8TB Seagate Externals have Archive (SMR) drives in them. It also shows drive temperature, firmware version, and of course lets you know if your drive is about to die by reading the S.M.A.R.T. data. I was getting very slow read times from jminer all of a sudden and I narrowed it down to one of my 8TB Seagate NAS drives. Sure enough, CrystalDiskInfo flagged it as CAUTION and I noticed the firmware version on that drive was SC60, whereas the firmware version on the drive which is still running fine is SC61. So I sent that bad boy in for RMA.
I imagine the tech at Seagate spinning it up and wondering why there are massive incomprehensible data files on it in a mysterious "Burst" folder. :)
@luxe How about WD My Book 8TB. Are those SMR drives as well?
- As far as i know only seagate uses SMR drives
@pr0cesor So i would say no they are PMR ... this one even uses 8TB RED drives:
