hd jumpers - is "Cable Select" best?
I have a Compaq Presario S4020WM purchased from Wal-Mart last year. I
replaced the original hard drive with 120G and 80G drives. My question is whether it makes a difference in performance whether I selected Master and Slave for the jumper settings, or Cable Select for one or both of them? I can't remember offhand. Of course I can open up the computer case and look, but I'd like to know beforehand if possible. This question is prompted by the fact that I'm getting slow hard drive access with my primary application, slow enough that it is slowing down that program significantly, and I don't think that is supposed to happen. Most other people using the same application and ordinary PCs don't report such a problem. I suppose this could also be a problem with bus speed and the motherboard, but I don't know about such things. Also in reading I notice that the channels used by the drives are important, but I don't know how to check them. Any advice appreciated. They're both Maxtor drives, and of course they're on the same Maxtor IDE cable - one at the end connector, the other on the middle connector. Here's some system specs: 2.00 gigahertz AMD Athlon XP 992 Megabytes Installed Memory Board: KM266-8235 Motherboard Chipset VIA VT8375 ProSavageDDR KM266 Bus Clock: 133 megahertz BIOS: Phoenix Technologies, LTD AM37320 08/01/2003 S3 Graphics ProSavageDDR [Display adapter] MAXTOR 6L080J4 [Hard drive] (80.05 GB) -- drive 1, s/n 664213219209, rev A93.0500, SMART Status: Healthy Maxtor 6Y120P0 [Hard drive] (122.94 GB) -- drive 0, s/n Y31WBLZE, rev YAR41BW0, SMART Status: Healthy -E |

The original IDE cable is a Cable Select cable. so the drives should be

I found that the drives were jumpered for Master and Slave. I made the
change to Cable Select for both drives. It didn't work at first, and I don't know why. I had to reseat the jumpers and power plugs and reboot several times before the main drive would boot. But now it's working OK, and there appears to be no change in performance for the drives. Thus as long as it's working, there's no reason to change to Cable Select from Master/Slave. But of course I didn't know until I tried it. A negative side effect of my adventure under the hood is that my processor's fan now has a loud, high-pitched whine. It's too loud and annoying, so I'll have to fix it. Naturally I blew out the dust while I had the computer cover off, but that apparently caused the fan noise to start. I tried repositioning wires leading to the fan, but that has no effect. I'll have to take the fan apart and use some WD40, or replace it, I guess. -E "HH" wrote in message ...

If you blew the fan enough to make it spin, you may have damaged it.
Some fans do not want to be spun except by the power. GH "Euclid" wrote in message nk.net... I found that the drives were jumpered for Master and Slave.

Oops...
I took the computer cover off again and did some trial & error disconnects. It was the 80G hard drive that was putting out the high-pitch whining noise, not the fan. I didn't change or do anything that should have affected it. Possibly it was making the noise beforehand and I got used to it, so didn't notice it. But it's annoying enough that I unplugged it, now all is OK. I don't really need it except for occasional system backups, then it's easy enough to plug it in again temporarily. I won't replace the 80G drive with another IDE/ATA drive because I want a SCSI drive next time, for the extra speed. My special application needs it. I suppose that will require a PCI adapter card, but I've got 2 open slots so that shouldn't be a problem. Don't know anything about SCSI otherwise, except rotational speed is a factor - at least 10,000 rpm, preferably more. -E "GH" wrote in message ...
