Spinpoint F4 HD204UI 2TB 5400 RPM working good so far

Hey everyone,

I just installed 2 of these drives in my ReadyNAS duo myself.
I updated the firmware to 4.1.7-T60 and started a Factory Default from FrontView, after which I used RAIDar to set the device to Raid 1 mode.

Everything seems to work fine, it's syncing now at 90 to 100MB/sec ... however Hingy here said the partition logs for him now show "disks are aligned for the 4K sectors"
I've looked in partition.log and can't find anything that would suggest 4K sectors :-/

The Log looks like this now:

Raidiator_version.log says. RAIDiator!!version=4.1.7-T60,time=1287008617

Is this OK ?
Thanks!

That's fine. You can see the start numbers are divisible by 8 and the first one is 32, which is what you expect to see with 4k sector alignment on Sparc ReadyNAS. Remember 512 bytes * 8 = 4k

mdgm

if one wanted to add another one of these 4k drives in the future can they be added without a factory default if the previous drives have already been aligned with a factory default?

Thanks very much! Sync is done now, and it looks like everything's working just fine :)

I think that should work.

thanks mdgm.
i now have running 1 hitachi 2TB off the HCL and 2XSamsung F4s with 3.6T total
I plan on adding another samsung 2TB next week for a total of about 5.4TB

i factory reset the first three drives and everything looks ok but wanted to make sure i got 4K properly set up.
below is my partition log:
thanks again for all the help on the forums!

I basicly asked the same question yesterday, and since this was mdgm's answer:
"You can see the start numbers are divisible by 8 and the first one is 32, which is what you expect to see with 4k sector alignment on Sparc ReadyNAS. Remember 512 bytes * 8 = 4k"

I think you're fine :)

thanks i did see that after reading the post closer.
thanks again for the confirmation- always good to have another set of eyes!

I currently have 3 HD2030WI drives in an NVX Pioneer with firmware 4.2.15 and want to add a 4th drive. Does anyone know if I add a new HD2040UI, would I have a problem with sector alignment since this is the first 4k drive added to my volume? Or would I still have to do a factory default?

Thanks.
