Installation error. Command returned status 36

[Viacheslav Chumushuk]

Hello.
I'm trying to install FreeBSD 7.0, but I have next problem.
When installation program write new partitions structure to disc it exits with 
next error: "Unable to make new root file system on /dev/ad1s1a! Command 
returned status 36".

And at the start of installation process I have warning about wrong disk 
geometry.

My HDD is Segate ST340810A 40Gb, and I was trying write geometry (which I 
found on its case and in BIOS), but without success.
The same problem with FreeBSD 6.2 and another my HDD.
But hardware looks good, because Linux and OpenBSD was installed without any 
problems.

Thanks for help.
