It is not only IE 9 but before April 2014
USB 3.0 is going to be common and right now Windows XP 3 don't support it and as far as I know, it is never going to be supported.
Hard drives are about to undergo one of the biggest format shifts in 30 years. :'(
By early 2011 all hard drives will use an "advanced format" that changes how they go about saving the data people store on them.
512-byte sectors have been the norm for decades. The 512-byte size was itself inherited from floppy disks, making it an even older historical artifact. The age of this standard means that it's baked in to a lot of important software: PC BIOSes, operating systems, and the boot loaders that hand control from the BIOS to the operating system. All of this makes migration to a new standard difficult.
Instead of storing 512-byte sectors, hard disks will start using
4096-byte sectors. 4096 is a good size for this kind of thing. For one, it matches the standard size of allocation units in the NTFS filesystem, which nowadays is probably the most widely used filesystem on personal computers. Secondly, it matches the standard size of memory pages on x86 systems. Memory allocations on x86 systems are generally done in multiples of 4096 bytes, and correspondingly, many disk operations (such as reading to or from the pagefile, or reading in executable programs), which interact intimately with the memory system, are equally done in multiples of 4096 bytes.
Phoenix produced preliminary BIOS support for the specification in 2005, and Microsoft, for its part, ensured that Windows Vista would support the new sector size. Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 all support the new sector size. MacOS X supports it, and Linux kernels since September 2009 also support it.
The big obvious name missing from this list is Windows XP (and its server counterpart, Windows Server 2003). Windows XP (along with old Linux kernels) has, somewhere within its code, a fixed assumption of 512 byte sectors. Try to use it with hard disks with 4096 byte sectors and failure will ensue.
