Ken R. Posted February 9, 2011 Share Posted February 9, 2011 I foresee a problem up coming with the two new Hitachi 5K3000 HD's I received today. Both disks are being precleared now, looking at the disks in unmenu I see that they are reporting a size of 1,953,514,584 where as my existing disks all report 1,953,514,552. Is this going to be a problem assigning them as data disks or will the size be smaller when they are formatted? Link to comment
BRiT Posted February 9, 2011 Share Posted February 9, 2011 Do you have or ever had the drives (old or new) connected to a Gigabyte motherboard? If so, make sure you have any BIOS options for "Backup BIOS to Hard Drive" turned off or disabled. It may be creating an HPA (Host Protected Area) on your drives. Wow, I misread the numbers, so strike that. For further debugging purposes can you post a full syslog of your system for us to analyze? Also possibly 1 dump of hdparm -I /dev/sd# where /dev/sd# refers to the full drive (such as /dev/sdc or /dev/sdg), may be of interest to us in finding out how this Hitachi drive behaves. This is the first time I've seen a 2TB drive report anything other than 1,953,514,552 as the total sector size. If it does indeed report a larger number of sectors than other drives, the only possible solution moving forward is to make the first one the parity drive. Link to comment
Ken R. Posted February 9, 2011 Author Share Posted February 9, 2011 Oh rats, you were supposed to tell me they will be fine after partitioned. Here's the syslog. Never owned a gigabyte board. syslog-2011-02-08.txt Link to comment
BRiT Posted February 9, 2011 Share Posted February 9, 2011 I'm looking through the syslog now. I also updated the previous post as initially I misread the numbers. I haven't used unMENU on newly unformatted disks so I cant say, however I think it will be alright after it's formatted. I'm basing this on the fast that your syslog reports identical number of sectors for your existing 2TB drives (WDC EARS, Seagate LP) and the Hitachi drives. They show 3907029168 sectors.

BRiT Posted February 9, 2011 Share Posted February 9, 2011 Updated previous post. I forgot editing a post doesn't display a new post indicator, so forcing one now. I think you'll be fine. Link to comment

aiden Posted February 9, 2011 Share Posted February 9, 2011 Please keep us posted, as I will be building a new server this weekend using 2 of these drives. Link to comment
Ken R. Posted February 10, 2011 Author Share Posted February 10, 2011 Drives cleared perfectly with a Total Elapsed Time 25:07:52 and a high temp of 27c. No changes in the smart report, No problems adding to the array and the formatted size is correct. Link to comment
BRiT Posted February 10, 2011 Share Posted February 10, 2011 That's a relief. It's good to know at least 1 new Hitachi 5K3000 drives is within the expected performance ranges for 2TB drives on preclear and so far it's working. Link to comment
