Rogue Cancels in this group?; was Gremlins..

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.

That is just plain wrong, and they flout the ATA standard.

And no non defective legal cable will produce
that dramatic reduction in thruput, to 2MB/sec.

so will probably go with a quality round cable no
more than 18" (as per Rod's recommendation).

Havent noticed them going here.
