I have an Epox motherboard with VIA chips (incl. KT600), AMD Athlon XP2700+,
512 MB RAM (400 MHz), 2 IDE ATA hard drives, 2 IDE DVD drives and a recently
installed Maxtor 160 GB SATA drive. I've installed the latest BIOS updates,
XP upgrades including SP2 and VIA's latest 4in1 and v3.00 SATA RAID driver.
The PC hasn't had problems when I save, copy or move data in and between the
IDE hard drives. However, when I copy or move files from an IDE hard drive to
the SATA drive, the whole transfer (the biggest ones I've tried where 5-10
GBs) is sometimes fine, but more often it gets only partly done before
suddenly either my PC tilts and boots or I get the good old "Windows Explorer
error message".
Reading from the SATA drive (e.g. DV AVI video to Media player) seems to
work fine.
I've tried a.o. by changing the SATA Interrupt setting in the BIOS to IntB,
with no improvement in the situation. Also tested with slowing down PC speed
by decreasing the multiplier, but no success with that either.
What might be the magic behind the problem and the fix.
