New Hard Drive - Form Factor

  Zak 20:25 31 May 2003

Just about to buy a Maxtor DiamondMax Plus9 60GB UDMA133 HDD.

It is to be fitted into a Dell Dimension PII 400Mhz. I have internal bays for 1 inch high HDD.

It seems to me it that my choice should fit ( 2.6cm = 1 inch)

However the Dabbs Product Information gives these details, part only.

Device Type Hard drive - standard
Width 10.2 cm
Depth 14.6 cm
Height 2.6 cm
Weight 0.6 kg
Compatibility PC
Hard Drive
Form Factor 3.5" x 1/3H
Enclosure Type Internal
Capacity 60 GB
Interface Type DMA/ATA-133 (Ultra) Fast Drives

I am confused by Form Factor value of 3.5" x 1/3H. I am OK with 3.5" - HDD diameter, but what is the 1/3H?

I just want to be sure it will fit the bay in my case.

1/3H = one third height - or 1". See click here for an explanation

Incidentally, the 3.5" refers to the size of the floppy disk - it does not actually relate to the diameter of the HDD platters. However, it is the commonly used description for a standard HDD.

Order it, I'm sure it will fit :)
