Never had any HD corruption problem with the Promise controller on my
two A7V133 boards I used for years.
Same here, no problems for years. One reason for corruption especially
on large files was reportedly due to cross talk with sound blaster live
cards.

"Question I am having trouble with a system using a VIA chipset
including a 686b southbridge and a Creative Sound Blaster Live card.
Answer When the 686b southbridge was first released, motherboard
manufacturers and VIA discovered a problem when trying to transfer files
between the primary and the secondary IDE channels on motherboards using
ultra-DMA, when a Sound Blaster Live was plugged in and drivers
activated. This issue was caused because too much noise is transferred
across the PCI bus by the Sound Blaster Live driver set. In an attempt
to fix this issue, some motherboard manufacturers modified their BIOS.
In some instances, these modifications to the BIOS caused a data
corruption error even when not using a Sound Blaster Live. VIA released
a patch which resolves this issue, which is incorporated in the 4in1
drivers from the 4.31 version onwards. Motherboard manufacturers were
advised to change the modifications made to their BIOS to eliminate the
data corruption issue. If you are experiencing data corruption or lock
up when transferring files between two IDE drives: 1) Make sure you have
the latest BIOS from your motherboard manufacturer. 2) Make sure you
have the latest 4in1 drivers 3) Make sure when you set up your system
that you install the 4in1 drivers both before and after you install the
SBL to make sure that the drivers see your SBL and install the correct
patch. The patch will only install if the SBL is installed. "
