Can someone unravel this Harddisk engineering mystery; Seagate ST336754LW 36GB SCSI U320 15K rpm 68pin 8MB Hard Drive 1platter Very high frequency Samsung HD 160G 7K 8M SATA2 HD160JJ R 2 platter High frequency Western Digital HD 250GB 7200RPM 8MB WD2500JB% 3 platter High frequency Maxtor D740X-6L NO...

Felger I said the same thing after your first post. I think this is an electrical noise problem and NOT an mechaical noise problem. As I have mentioned before, I have noticed this on Graphics cards, and most notably on Ethernet cards (or built into the mobo), however, Feleger has got me thinking ag...

I think he has an electronic problem, not an acoustic problem.

wearing earplugs will eliminate the annoying high frequency headache so it is accoustic/sound waves

Okay, I misunderstood what you meant by comparing to EIDE drives from other systems. Do you know anything at all about the rotational speed of the EIDE drives in question? The frequency of the noise in 5400rpm drives is lower than 7200rpm drives. It is the rotational speed which will determine the ...

I am comparing the eide/ sataI from other systems That is a mistake. You should: 1. Remove all hard drives from your main computer and power it on. See if the noise is a problem. Obviously, the computer won't boot up, but you can still POST. 2. Unplug all fans except for the PSU fan. With the PSU f...

The noise might not be from the hard drives if it's the motherboard and/or power supply interacting with usage of the SATA/SCSI ports. However, it seems strange that it would occur specifically with SATA II but not SATA I. Theoretically, there should be no difference. Are you SURE it's not somethin...

As I was reading this post, I started thinking Electronics NOT platters/motors etc. Felgers post made me post myself. SATA whines but PATA doesnt, that makes no sense to say that the noise in mechanical as the mechanics are identical, however the electics arent. I have noticed quite a few mobos wit...

If it's high frequency noise, then it should be possible to absorb/block it with some thick foam-like obstacles. I have had success with putting pillows all around my file server. The intakes/exhausts are all to the rear, so I have a large gap between the rear of my server and the wall. Against the...

That would probably be the whine of the motors of those SCSI drives you have installed. Most SCSI drives run at least 10,000rpm and the higher end ones will go all the way up to 15,000rpms. They are NOT meant for silent running. In fact, you might say noise is not a concern in the design at all. Lo...

Hi, I am setting up a custom desktop and tried to install 3 different types of SCSI and SATA II drives and I instantly get a headache being next to the desktop. Although I cannot hear the noise the "ultrasonic" sound waves affect my ears and then cause disorientation...I am fine with ear plugs... ca...
