Installer shows incorrect disk size

Hi all,

I tried to do a test install of VE on a HP Microserver Gen8 and encountered the following discrepancy when choosing the target disk.
Currently 5 drives are installed:
2x 1TB WDC WD10EACS-65D6B0 which are correctly shown as 931GiB
2x 2TB Hitachi HDS5C3020ALA which are incorrectly shown as 1TiB
1x 120GB Vertex3 SSD which is also correctly shown as 111GiB

I'm a bit confused why only the 2 Hitachi disks seem to be not recognized with their full capacity. Does anyone have a idea what could cause this?
I guess that's not the normal/expectad behaviour of the installer?

Regards Flo

I see what you mean - it's a display bug (cutoff after the decimal point instead of rounding) - but as said only a display bug - the disks will be used with their full capacity

We'll try to come up with a patch to fix this :)

Thanks for reporting the issue
