Hard drive questions

Hard drive questions.

I a little confused on how to find out what type of hard drive
purchase.

I have an ide cable going to the hard drive.

So will any ata100 drive work?

One reps said they are not backwards compatible with non-ata or lower
ata specifications

My current drive info say
It is a western digital

ATA # Supported 5,4,3,2,
MW DMA Suport 0,1,2
MW DMA Cycle/Word 120ns
MW DMA Active
Ultra DMA support 0,1,2,3,4,
Ultra DMA Active 4
IORDY Support Yes
PIO Mode Support 3,4


So what type of Ata drive do I have?

There should be a label on top of the HDD that will tell you the make,
model and capacity of the drive.

What are you purchasing it for? A replacement or an additional drive? You
can add just about any drive on the market if you wanted to depending on
your budget. Have you ever installed one before? What System will you be
adding this to?

Okay, I'll play your silly game.
Drive fits the 2nd ATA convention specs.

For all practical purposes, ATA = IDE

 

[Al Dykes]

Any desktop PC purchased in the last bunch of years will work with any
IDE disk you can buy today, and vice versa. There will be, at worst,
very modest performace redustions.

The only thing to watch for is a disk larger than 132 GB in a machine
more than a year or so old. There are some OS and BIOS issues, none of
them unsolvable.

Duh, But ata133 is different then ATA100 and so on.

That much I do know.

Here is the drive I have
http://support.gateway.com/s/HARDDRV/Westernd/5502165/550216502.shtml


WD400EB-00CPFO

At the bottom of the page it says
Optional feature ATA 100

Optional?

I am going to be putting the hard in a xp computer. I just don't want
to have to buy a pci card to make the hard drive work.

I am assuiming it came without that option.

No, I don't have a gateway computer.

Where and what resulted in this as your choice of hard drives? You want a
40 Gig drive sold by Gateway that is 5400 RPM and made by another
manufacturer?

 

[Bob I]

It should work just fine, plug in the actual model number from the drive
in here for everything you ever wanted to know about the drive.

I didn't say I was going to pick this drive. This is the drive I
currently have without the ata/100 interface.

IT DOESN'T MATTER. Any 40G disk will work fine in any PC made in the
last 5 years, or more. If your PC is older than that , it'll work but
you may need a trick to get abeyond the old 32GB wall.

ATA, IDE. It's all the same thing for your purposes.

Because the UDMA Support level is Mode 4, this particular drive
is not ATA-100, which is UDMA Mode 5. If this drive is attached
to the same IDE cable as an ATA-100 drive, the latter drive will
function in UDMA Mode 4.

Uh, I think you are referring to a problem from years ago. All current
PCs maintain independent speed tables for each IDE HD, and so each HD
transfers data at the max. speed which both the PC and that HD support,
without regard to the speed used by other HDs on that or other IDE cables.

 

[Jonny]

So the hard drive backpedals to UDMA100, so?
