Hi all,

my dual g5 ADC Student order was placed yesterday; from then I begun the search fot the internal 250MB model number. Here at MacNN I went to this thread:

http://forums.macnn.com/showthread.p...hreadid=179077

where "whitey" said that Apple System Profiler calls the internal 250MB a Maxtor 6Y250M0.
Well, checking at Maxtor this HD model do not exists, while the 6Y200M0 and 7Y250M0 both exist.

So, what is the truth? Is Apple cheating HD capacities (I heard something somewhere) or simply it is an OEM model not available in retail stores?
Checking at www.otherworldcomputing.com I've found both 6Y200M0 and 7Y250M0 from Maxtor but not the infamous 6Y250M0.

What I have to do if I want to pair my internal 250 HD when the dual arrives?

Thanks
Sam

Model numbers should not be an issue between two drives. Just install and go!

I wouldn't be suprised if the Apple hard drive is made directly for them by Maxtor, using a model code that is different than what you can buy retail. I wouldn't worry about it. Get the Maxtor drive that looks like it has all the same specs and you'll be OK

The bit about "cheating" with hard drives is something different - the fact that hard drive manufacturers advertise 1GB as 10^9 bytes , while your computer considers 1GB to be 2^30 bytes , which is about 75 MB more than 10^9 bytes. This is in addition to the fact that formatting a drive uses some capacity also. Back when hard drives were sold by MB, nobody really cared all that much, but now your 250 GB drive will show up at around 230 GB because of this odditity in the math. There was a lawsuit filed against this practice that is going after not only the HD manufacturers, but the computer retailers that use those HD size values, including Apple.

(It should be noted that 10^9 is the proper interpretation of GB according to the SI, and they are trying to call 2^30 a GiB instead, but nobody likes a Math geek.

)

Yeah I'm wanting to buy another 250, do you think the 7Y250M0 is basically the same thing? Are there any other retail 250Gb drives other than the maxtor and WD?

I just did a 6Y250M0 Google search and about a bazillion pages showed up.

Note the 250 part too, which means 250 GB.

Typo. If you look at the first link they show both 250 GB and 160 GB in the same ad.

Look at the other links. It exists, it's 250 GB, and it is for sale.

Then maxtor.com did not update its site. I hope...

Or is not a DiamondPro9 but a MaXLine Plus II which exists as a 250 GB and the code listed by Apple System Profiler is wrong.

You're really not searching very hard. It's a Maxtor DiamondMax Plus 9 250 GB drive.

The Apple System Profiler is correct. I already gave you the Google search results. It's right in there.

Hard drive manufacturers have always used different part numbers depending on whether the drive was made for OEM or retail sale. Owners of OEM drives must obtain warranty service thru the reseller, while retail drives can be RMA'd directly to the drive manufacturer for service or exchange.

Eug . . . you've got to stop covering for Apple. They obviously are advertising this machine with a 250 GB hard drive, but really only selling it with a 160 . . .

Oh, I know what it is, Apple OVERCLOCKED the hard drive to increase it's capacity!
