What is the maximum hard disk size on windows?

Answer 1

The current maximum size of an NTFS partition is 16 exabytes (18 billion gigabytes). Assuming you can divide up the drive into four primary partitions, you can have 64 exabytes on a hard drive. Of course, Windows still uses BIOS addressing to find the size of a hard drive, so it is still limited by what the BIOS can see. Currently, the newest BIOSes support a maximum of 144 petabytes (144 million gigabytes).

Answer 2

If you have loaded XP over an older version of Windows it is possible that you're still running FAT-32, in which case your partition size is severely limited.

However, if you've converted your file system over to NTFS your maximum disk size and maximum partition size is 18 billion gigabytes.

That also depends on having a BIOS that is capable of handling the larger disks.

Answer 3

Windows XP relies on the BIOS to get the correct drive geometry, so it can't use more than the BIOS supports. With LBA48, most BIOSs these days can support hard drives up to 144 PB (which don't exist yet). The NTFS file system supports up to 16 Eib for a partition.

Answer 4

Whats the biggest one that you can afford. The operating system doesn't determine the max size of the Hard Drive. However XP does limit the size of your usable RAM (memory to 4 GB). The difference would be determined by what type of interface your motherboard uses to connect to the hard drive. It would be either IDE (really wide plug with 40 pins and a ribbon cable) or SATA (small plug with about 4 pins and a cable about the size of a phone cord). Although a large hard drive (500GB to 1TB) can be found for either one it is easier to find (and sometimes cheaper) for the SATA.
