As you see below, DNS-323 see 1.5 T WD as 500G Drive:

 Vendor       Model       Serial Number       Size
 WDC     WD15EADS-00P8B0     WD-WMAVU0180057     500 GB

H/W: B1
F/W from 1.05 to 1.08

any ideas ? Do any of you have seen similar behavior ?

Someone else posted a similar story, they formatted to 500gig.  I suspect this is a real issue with the firmware.

I have 2 of those drives in a RAID 1.  They formatted to 1.5 TB and have been working fine for a month now.  Firmware 1.07

Hi,

Actually i have four of those drives, each of them is working fine with PC. Only diff i have found is serial number eg:
WD-WMAVU0172667 works fine
WD-WMAVU0180057 - DNS-323 shows only 500G

(Even HD's FW is the same - FwRev=01.00A01)

What serial numbers your drives have ?

Regards

[mrg]

i will check tonight.

Where the drives previously installed and formatted on your PC? If so I would recommend inserting them back into you PC and removing all partitions before formatting in the DNS-323.

Here is my drive info.

Looks like it is a kernel level problem. i checked my disks on DNS-323 with telnet support (modified FW 1.05), results are below:


 WDC     WD15EADS-00P8B0     WD-WMAVU0172667

SCSI device sda: 2930277168 512-byte hdwr sectors (1500302 MB)
SCSI device sda: drive cache: write back


 WDC     WD15EADS-00P8B0     WD-WMAVU0180057

SCSI device sda: 976817134 512-byte hdwr sectors (500130 MB)
SCSI device sda: drive cache: write back

As i said before, regular PC recognizes this drive correctly:

[    4.253642] scsi 2:0:0:0: Direct-Access     ATA      WDC WD15EADS-00P 01.0 PQ: 0 ANSI: 5

[    4.253732] sd 2:0:0:0: [sdc] Write Protect is off

root@lpl-pc-gb:~# smartctl /dev/sdc -a | grep Serial
Serial Number:    WD-WMAVU0180057

root@lpl-pc-gb:~# uname -a
Linux lpl-pc-gb 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux

Any ideas ?

What does it do with the latest beta?

[rlukawski]

What does it do with the latest beta?

i checked out with 1.08b05 and 1.08b07 (without telnet support) - web interface showed 500G so i think kernel behavior most probably is the same...

[rlukawski]

Hi

Do you have any idea which kernel version is in 1.07 or 1.08b05 ?

Works fine here too.

Hi All,

It seems i've solved the problem, this is not DNS-323 related but WD.

I've noticed not only i had that bizzare situation when OS/Device raported 500G instead of 1500G - problem is HPA (Host Protected Area) which was set like that:
user area: 500 G
hidden area: 1000 G (Drive was brand new, originally packed by WD)

I hope it might be helpful - if you encounter similar problem use SW which allow to change HPA, eg: http://www.hdat2.com/

Kind Regards
Rafal
