R1A2 Intallation to HD Partition

Hi, I have (actually had now) R1A1 working nicely on a PATA HD partition booting from GRUB 2 menu and it worked very well. Have just tried to install R1A2 to the same partition but the installation keeps locking up with a "general error" either during or just after copying the libweb .so file.

I have tried re-initialising the partition but it makes no difference.

My hardware is
Intel Core2Duo 6400 @ 2.13GHz
Gigabyte EP41-UD3L
4GB RAM
ATI Radeon 4850
Maxtor 7Y250P0 PATA IDE drive

Does anyone have any ideas? I seem to be able to install R1A1 just fine.
