1 GB = 1024 MB I thought & not 1028,or am I wrong? All Macs are PCs but not all PC's are Macs. Try explaining that to someone that only understands Windows.-----Original Message----- From: Peter <[EMAIL PROTECTED]> To: g3-5-list@googlegroups.com Sent: Thu, 4 Sep 2008 20:22:49 -0700 Subject: Re: Disk Partition Size Limit On Sep 4, 2008, at 1:09 PM, insightinmind wrote: > 1GB = 1028MB, and not 1000 MB, > If you read the device's characteristics, it says it's capacity is 1000 megabytes. > and that when a disk is formatted, you "lose" space due to maintenance > / indexing / allocation needs of the system ... maybe even bad sectors > being mapped out. The maintenance cylinders are not visible to the user, although they are there. The manufacturing process provides the user with 1000 megabytes of fully usable, fully contiguous blocks, with blocks numbered from zero to n-1. Even with the least complicated initialization for MacOS, there will be around nine partitions which are present and are reserved for system use, such as holding the SCSI boot loader, or the IDE boot loader, or the Firewire boot loader, or the SATA boot loader, plus a patch partition, etcetera. The first user-accessible partition starts after those partitions. The initial director space comes out of the user-accessible partition space.
