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.pdfCroydan

@croydan1 Both the 8TB and 5TB drive are SMR drives i guess ... thats what i had in this external drives ...
http://geizhals.eu/seagate-desktop-hdd-5tb-st5000dm000-a1118253.html (5TB)
http://geizhals.eu/seagate-archive-hdd-v2-8tb-st8000as0002-a1204027.html (8TB)
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?
-
@socal
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)

@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?
-
@luxe said in Need Tech help on plotting:
- 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:

i got a WD 8GB feck they expensive or what! if i didnt win a 1 of auction, it wouldve cost $550! AU$ thankfully i won the pokies got it for $450 AU
*Anyhow its an over rated lack box looks like a black witch craft novel and it heats up too. i watched a short film how to take it apart and use the drive in the pc? I might just do that. A new model released looks like a seagate like enclosure they even have a gold colour to mach the huge premium lol
-
@ZapbuzZ Are u sure WD8GB or TB? In my country one WD 8TB cost around 279 EUR. Where did u get that crazy price?
Edit-
Forgot it;s an Australian currency :D But still too expensive for a WD. Look on ebay or amazon.
-
sorry i meant 8tb lol i'm from the days of floppy disks haha im not used of terrabytes
-
@ZapbuzZ If u have that WD 8TB it was a good choice. Me myself I will get one of them
-
I can't complain but the new design is so seagate-ish and comes in colours
