My Gigabyte 7dxr motherboard may be one of the first motherboards to be released into the distribution channel. My revision level is 0.2
In most respects it has performed quite well, however there have been numerous anomalies having to do with the IDE channels. I have spent a substantial part of this morning diagnosing a situation where I have been plagued by extremely poor performance when copying a hard drive from the primary IDE channel to the secondary IDE channel, (referred to as IDE one and IDE two on the GB mainboard). It is my practice to you use drive cloning software, (ghost, drive image, and bootit have all been used during this diagnostic process with equally poor performance).
Last night I set two identical IBM deskstar disk drives cloning from one to the other. The drives are 45 GB in total capacity and around 35 GB was in use. These are almost new ATA 100 disk drives that should be capable of fine performance . This 35 GB process took eight hours at an average speed of 67 megabytes per minute!
A short while ago I set these drives up on the promise controller which had been put into ATA 100 mode , (not a raid controller). One of the drives had a 40 wire cable so it was not even running an Ultra DMA mode and yet the average transfer rate was almost 700 megabytes per minute , just about ten times as fast as the two drives ran when one was primary master and the other was secondary master.
My primary question is, “Why is the disk-to-disk transfer so slow from primary ide master to secondary ide master?
