A number of my replies in this group have either been cancelled or first
appear, then disappear on various servers (not due to no archive or time
limits).
So, I will keep reposting the substance of the replies, I don't have
time to track down whoever is doing this.
In diagnosing a box that keeps ruining drives, I ran benchmarks using
Fresh Diagnostics. Rod Speed asked if these were accurate. I can only
say that the 2MB/sec. speed I got from this program on the slave 8GB
(now part to 7GB) WD drive was confirmed by a manual timing of a 500MB
transfer. Even though WD DLG program reports the drive running in the
UDMA-66 mode, the figures I am getting do not reflect this. Since
resetting/cleaning the power connections I have had no further drive
crash problems, but I think transfers from one directory to another in
the Master 20GB drive still are extremely slow on directories that
appear to be on disparate areas of the drive. I now have hdtach, but not
sure if I have the complete version that allows both read and write
testing; also reports of bugs with this program under win98.
The figures for the master drive are 20MB/sec read and right,
approximately, so am not too worried about that drive. But 2MB/sec is
definitely too slow for the other drive. Thinking of replacing the cable
and slave drive with a seagate.
Found some more tests of flat vs round cables and generally the round
cables are superior in speed to the flat cables. The reading I have done
suggests that the flat design is more prone to cross-talk and other
interference and twisted pair round cables are better, so will probably
go with a quality round cable no more than 18" (as per Rod's
recommendation).
Now I am saving my posts so I can easily repeat them if they
"disappear". Maybe they are on servers I am not using, but I checked
several servers and they are gone.
