I need to buy a new hard drive and clone my old one onto it (because the old one is corrupted and I don't want to risk an operation like chkdsk (which would write to the drive) on the original). The reasons for the clone are detailed elsewhere on this forum here, where I am already being helped by some of the kind pepole on this forum.

Since the drive I need to clone holds a copy of Windows XP, I've been looking for a 2TB drive (the max. XP supports I believe) with 512 byte sectors (XP predates Advanced Format I believe, and doesn't support even 512e drives). I also want the new drive to be a least as fast as the old one was (it was a 7200rpm drive), so my video editing software etc. runs smoothly as it did before. The drive in the topic title (Seagate's BarraCuda Pro ST2000DM009) seemed to fit the bill, but I have some queries about certain details of the drive.
  • Is this really a 512 native drive? Seagate's data sheet for the BarraCuda Pro series lists all the drives as having 512 byte sectors, but I have seen at least one of the larger models (12TB or 10TB) listed for sale as a 512e Advanced Format drive, so the data sheet might be incorrect.
  • Is this drive suitable for stand-alone use (ie. not in a RAID)? (I ask because the 'Pro' in the title leads me to worry that this might be an 'Enterprise' model with TLER/ERC enabled).
  • When was this model released? My hope is that it is new enough that Seagate have fixed whatever it was that made some of their BarraCuda drives rather unreliable (somebody sued Seagate I believe).
Are there any other important factors in selecting a hard drive to buy (for an old PC) which I may have overlooked?

1. Yes. See page 4 of the manual.

2. Yes. 

3. Not sure. Contact Seagate. I think Oct or Nov 2016 per the manual.

Interesting.  Must be one of the few 512 byte native drives they still make.  According to this briefing, all new drives released after 2011 were expected to be Advanced Format.

 

I haven't got any of the Barracuda Pro models, but I do have a 2 Tb ST2000DM001 and a 3 Tb ST3000DM001, and they are both Advanced Format (512e).

 

My understanding is the Barracuda Pro models are marketed to the high end desktop sector (creative professionals etc.), and feature a longer warranty than the non Pro models.  They are not intended for use in servers (although the bumf does say they can can be used in "Home servers" which honestly any old drive can be).

Thank you both for your replies and sorry I did not acknowledge them at the time. You provided some reassurance which led to me buying one of these drives which is now in my PC (still in the progress of recovering from the problems with the old drive as JohnC_21 will know as he has been helping me with this in another topic).

 

Anyway, I am posting here with an update since I have been running smartctl on the new drive and it is reporting a 512 byte sector size so that's good for me.

 

What's not so good (I think) is that I just ran

smartctl -l scterc /dev/sda

and the result was as follows:

SCT Error Recovery Control:
	Read: 	70 (7.0 seconds)
	Write: 	70 (7.0 seconds)

Just as I thought I was getting close to having my video editing PC back; now I'm not sure if I can trust the new hardware which seems to be designed for a RAID and I am not using it in a RAID.

 

Does anyone here have experience with TLER/ERC and in particuar whether there is a way to turn it off and be sure that it won't turn itself back on? If so, I'm assuming turning it off would be a good idea?
