Hard Drive Capacity Limitations


or read our Welcome Guide to learn how to use this site. The IEC's binary megabyte notation was intended to address the confusion caused by the fact that this capacity is referred to as 528 by drive manufacturers, who consider a megabyte to And starting in 1999, no new Macs shipped with SCSI ports by default, although some Power Macs could be ordered with a SCSI PCI card. The first ATA specification increased that to 28-bit addressing to support drives up to 137 GB (128 GiB). http://zuneuser.com/hard-disk/hard-drive-size-limitations.php

Thanks in advance. Most will arrive with a little jumper installed on a pair of pins - the only jumper a SATA drive needs. to the point, can my configuration support a 1GB HDD without slowing down the machine? If you want to know more about any one of them just go back to the text.

Hard Disk Capacity Range List

Most, if not all, of today's disk drives support both Logical Block Addressing (LBA) and Cylinder Head Sector addressing (CHS), however history shows us that BIOS's have used CHS addressing. Mac Size Limitations Early versions of the Classic Mac OS (prior to 7.5.2) have a 2 GB limit per partition, so higher capacity drives need only be partitioned into multiple 2 GB This information is then stored in the CMOS.

Back to: IntroductionContents1. Often manufacturers have programmed the BIOS with a limitation. The Int 13 API Interface The Int 13 API interface is also a register driven interface. Hard Disk Drive Storage Capacity It could be a relatively minor file system problem or there could be major physical problems with the disk that will make recovery of the data difficult.

and about the data recovery question, any EXPERT suggestions from anyone (including the above 2 gentlemen), in this forum? Hard Disk Storage Capacity Chart The 4.2 GB limit (Feb 1997)Simple BIOS translation (ECHS=Extended CHS, sometimes called `Large disk support' or just `Large') works by repeatedly doubling the number of heads and halving the number of For example, this means if you try to install a 20gb hard drive, your system will only recognize the drive as an 8.5gb. http://www.dewassoc.com/kbase/hard_drives/drive_size_barrier_limitations.htm Register a free account to unlock additional features at BleepingComputer.com Welcome to BleepingComputer, a free community where people like yourself come together to discuss and learn how to use their computers.

First, let’s understand how data are stored on hard disk drives. Hard Disk Drive Strengths PC Drive Interfaces Interface When Used ST-506/412 1978-1989 (obsolete) ESDI 1983-1991 (obsolete) Non-ATA IDE 1987-1993 (obsolete) SCSI 1986-present PATA (IDE) 1986-present SATA 2003-present ST = Seagate Technology ESDI = Enhanced Small Start a free trial today.

Hard Disk Storage Capacity Chart

what is the maximum capacity, interface, speed, etc., blah, blah, of [one or more] hard disk(s) supported by this configuration? my site on a side note, as i had already asked in my 1st post, can i know about the feasibility of recovering data from the FAILED HDD? Hard Disk Capacity Range List Related You must log in to post a comment. Capacity Of Hard Disk In Computer Problem is, when you combine the two, you get a real world limitation of 1,024 cylinders, 63 sectors, and 16 heads, which works out to 528 MB (504 MiB).

The disk address is viewed as a number of cylinders, each of which has a specified number of heads. navigate here The 3.2 GB limitThere was a bug in the Phoenix 4.03 and 4.04 BIOS firmware that would cause the system to lock up in the CMOS setup for drives with a SATA data cables are much smaller than those used by PATA, whereas the power cables are similar in size. This Int 13 API interface is operating system independent so that the two upper layers (Figure 1) could be MS-DOS® based, Windows® based, Apple® MAC, Linux or some other operating system Hard Disk Capacity Calculation

BIOS Int 13 - the 8.5 GB limitAt most 1024 cylinders (numbered 0-1023), 256 heads (numbered 0-255), 63 sectors/track (numbered 1-63) for a maximum total capacity of 8455716864 bytes (8.5 GB). The integrated configuration enables increases in the clock rate of the encoder and the storage density of the drive. Each side of a magnetic disc is divided into several concentric tracks or cylinders. Check This Out At 512 bytes per sector, this yields a maximum theoretical capacity of about 136.9 GB.

Reply to bobbknight Neil JonesJun 30, 2008, 3:33 AM I can buy a SATA 2 controller that plugs into one of my PCI slots and get all the benefits of SATA Hard Disk Drive Speed Besides that Windows NT can’t boot from partitions larger than 7.84 GB, you will need to create a bootable 7.84 GB partition and put the rest of the hard disk drive Other benefits of registering an account are subscribing to topics and forums, creating a blog, and having no ads shown anywhere on the site.

You will see this used more often as we discuss new technologies such as Serial ATA.

Multiplying this number by 512 will give you the total capacity of a hard disk drive in bytes. Therefore, the capacity of a drive can be determined by multiplying the number of cylinders by the number of sectors by 512. Figure 7.1 shows how the power and data cables SATA uses compare in size to those PATA uses. Hard Drive Disadvantages Table 7.1.

Smaller 2 1/2-inch ATA drives found in laptop computers use a superset 44-pin or 50-pin connection, which includes additional pins for power and configuration. History of BIOS and IDE limits ATA Specification (for IDE disks) - the 137 GB limitAt most 65536 cylinders (numbered 0-65535), 16 heads (numbered 0-15), 255 sectors/track (numbered 1-255), for a If so how do I determine what the largest size hard drive my BIOS can support? http://zuneuser.com/hard-disk/hard-drive-crashes-which-hard-drive-in-a-pc.php Back in 1986, 500 MB must have seemed like an incredible amount of storage space because the largest PC hard drives in those days were about 40 GB.

The original IDE specification supported 22-bit logical block addressing, which supported a maximum drive size of 2.1 GB (2.0 GiB). When a file is read, the file manager reads the directory to locate the file on the disk and then reads the file.
