    physical dimensions of hard drive
    « on: June 06, 2011, 05:06:34 AM »
     :-\

    I have an HP / Compaq Presario C700

    I hope to upgrade to 500Gb hard drive,

    I have been looking for a bargain priced one,

    I saw there was a 1Tb hard drive for sale because "It was too big to fit in the laptop purchased it for",

    I then wondered if this laptop would have any issue with physical size,

    I did consider the external option,
    But I learned of "partitions" - this would give us a bit of a safety net with a new internal,

    I could use the old hard drive for external storage

    I didn't have any luck with the HP website,

    The current hard drive is showing as 80Gb?
    Only have 11Gb left after 3years

    Thanks

    I don't understand what you are saying.

    Laptops like the Compaq Presario C700 use 2.5-Inch hard drives. The C700 specifically uses the SATA interface.

    As long as the new hard drive is a SATA 2.5" hard drive, it will work in the laptop.

    The use of the phrase "fit in" makes me think it was a 3.5 inch drive purchased in error (laptops take 2.5 inch drives). This is such an elementary error that I wonder if he might have meant that the laptop was an older one and the BIOS did not have LBA support and hence could not see a disk bigger than 137 (decimal) GB or 127 (binary) GB. Sometimes this can be got around sometimes not. However the C700 does not have this limit.

    Too big to fit could also mean the drive was too thick to fit in the caddy and/or opening.  This only applies to laptop drives.  Early drives were 12mm thick, later ones 9.5mm.
    "2.5 inch" drive: (2.75 in x 3.945 in x 0.374 in = 69.85 mm x 100.2 mm x 9.5 mm)

    But 1 TB drives are pretty late historically aren't they?

    So far, but there are plenty of 750 GB laptop drives that are 9.55 mm high.
