|Windows Vista support for large-sector hard disk drives|
Hard disk drive manufacturers will soon start producing hard disk drives for which the physical sector sizes are larger than the traditional 512 bytes per sector. For example, sectors may be 1 kilobyte (KB), 2 KB, or 4 KB. This change will enable manufacturers to improve the capacity, the performance, and the reliability of their hard disk drives. This article discusses Windows Vista support for large-sector hard disk drives.
Important: Dynamic discs are only supported in Windows Vista Ultimate, in Windows Vista Business, and in Windows Vista Enterprise. Generally, dynamic discs are not supported in Windows Vista Home Basic or in Windows Vista Home Premium. However, when you upgrade your computer from Windows XP Media Centre Edition to Windows Vista Home Premium, some dynamic discs are supported.
|After you connect an external hard disk drive or a USB flash drive to a computer that is running Windows Vista, the Import option in Windows Media Centre may not be available|
After you connect an external hard disk drive or a universal serial bus (USB) flash drive to a computer that is running Windows Vista, the Import option in Windows Media Centre may not be available. The Import option is used to copy files from removable storage devices to a computer for use in Windows Media Centre.

In Windows Vista, when you try to use the Create CD/DVD feature in Media Centre to create a slide show on a DVD or to create a video DVD, the computer stops responding. Or, you receive an error message that resembles the following:
Low Disk Space
|Incorrect report on disk free space under DFS|
The Disk Free Space reported in Windows Explorer or in a Command Prompt on a Distributed File System (DFS) client for a DFS share is always the Disk Free Space of the drive containing (hosting) the DFS root.
|Power consumption may be more than expected on a portable Windows Vista-based computer that uses a SATA hard disk that does not support Host-Initiated Link Power Management|
Power consumption may be slightly more than expected on a portable Windows Vista-based computer. This problem occurs if the following conditions are true:
|You cannot remove the volume after you convert the Windows Vista installation partition from a Basic Disk volume to a Dynamic Disk volume|
After you convert the disk partition on which Windows Vista is installed from a Basic Disk volume to a Dynamic Disk volume, you experience the following symptoms:
|A hard disk or a removable media appears as a RAW volume after you try to complete a full format in Windows Vista|
After you try to complete a full format of a hard disk or a removable media in Windows Vista, the full format is not completed. When you try to access the hard disk or the removable media, neither can be accessed. The hard disk or the removable media is a RAW volume.
Note: A RAW volume is a volume that has never been formatted and does not contain a file system. Examples of file systems are FAT, FAT32, and NTFS. Typically, programs that do not require a file system write to a RAW volume. These programs perform direct I/O operations to the RAW volume.
|The disk-drive numbers on a Windows Vista-based computer may not correspond as expected to the SATA channel numbers|
Consider the following scenario. You have two Serial Advanced Technology Attachment (SATA) hard disks attached to channels SATA0 and SATA1 on a Windows Vista-based computer. However, Disk 0 may not be assigned to the hard disk on SATA0, and Disk 1 may not be assigned to the hard disk on SATA1. You expect the disk-assignment numbers to match the corresponding SATA channel numbers.
|Windows ReadyDrive does not work in Windows Vista if the first partition of a hybrid hard disk drive has less than 32 MB of free space|
In Windows Vista, Windows ReadyDrive does not work if the first partition of a hybrid hard disk drive has less than 32 megabytes (MB) of free space. When this problem occurs, the operating system does not recognize the hybrid hard disk drive. Instead, the operating system uses this disk drive as a traditional disk drive.
|The option to upgrade a basic disk to a dynamic disk is not available on a portable computer|
When you try to use the Windows Disk Management (Diskmgmt.msc) console to upgrade your laptop or portable computer from a basic disk to a dynamic disk, you cannot do so. If you move an existing Dynamic disk from another system to a laptop, the disk will appear as foreign in Disk management. However, the option to import it will be dimmed.
|You receive a "Disk read error has occurred" error message when you use the Winnt32.exe program to reinstall Windows XP on a computer that has both Windows XP and Windows Vista installed|
When you use the Winnt32.exe program to reinstall Microsoft Windows XP on a computer that has both Windows XP and Microsoft Windows Vista installed, you receive the following error message:
Disk read error has occurred.
Additionally, the computer stops responding (hangs).
|Error message when you try to move a folder to a mount point folder that is located on the same disk in Windows Vista: "Access Denied"|
When you try to move a folder in Windows Vista to a mount point folder that is located on the same disk, you receive the following error message:
Destination Folder Access Denied – You need permissions to perform this action
This problem does not occur when you move the folder to a mount point on a different disk. Additionally, this problem does not occur when you copy the folder to the mount point folder instead of moving the folder.
|Problems with the network, hard disk drive, or storage drivers cause a program to stop unexpectedly in Windows Vista|
You start or run a network-capable program in Windows Vista. Then, the program stops unexpectedly (crashes) in either of the following cases:
Program_name has caused an error and must be closed.
|All dynamic disk volumes are removed and then re-created when you restore a computer by using Complete PC Restore together with the "Format and repartition disks" option in Windows Vista|
Consider the following scenario. You restore a computer by using the Windows Complete PC Restore program in Windows Vista. You use the Format and repartition disks option. In this scenario, all dynamic disk volumes are removed and then re-created. This behaviour occurs even if the dynamic disk volumes are not included in the restore process.
|You receive an error message when you try to save a file to a hard disk drive or to a flash device in Windows Vista|
In Windows Vista, when you try to save a file to a hard disk or to a flash device, you may receive one of the following error messages:
X:\Folder\FileName You don’t have permission to save in this location. Contact the administrator to obtain permission. Would you like to save in the Documents folder instead?
Access to X:\Folder\FileName was denied.
|You cannot access a locked Sony USB hard disk drive in Windows Vista|
Windows Vista does not recognize a locked Sony USB hard disk drive. Therefore you cannot access the drive.
This problem occurs because the USB device sends an incorrect status code to Windows Vista. Also, the device sends no additional sense code information before the device is unlocked. Therefore, Windows Vista does not recognize the device.
|Performance is slower than you expect when you read from or write to an IEEE 1394 (Firewire) hard disk that uses a VIA Technologies 1394 host controller in Windows Vista|
Consider the following scenario. You connect an Institute of Electrical and Electronics Engineers (IEEE) 1394 hard disk to a Windows Vista-based computer that uses a VIA Technologies 1394 host controller. However, performance is slower than you expect when you read from the hard disk or write to the hard disk. For example, you may experience decreased reading and writing performance of approximately 20 percent in Windows Vista when you compare it to Microsoft Windows XP with Service Pack 2 in the same test environment.
|You cannot install Windows Server 2003 successfully after you use Windows Vista or Windows PE 2.0 to create partitions on a hard disk|
You use Windows Vista or Windows Preinstallation Environment (Windows PE) 2.0 to create partitions on a hard disk. After you do this, you try to install Microsoft Windows Server 2003 on the hard disk without using Windows Server 2003 to repartition the disk. In this case, you cannot install Windows Server 2003 successfully.
Windows Server 2003 Setup will successfully complete the text-mode part of Setup. However, after the text-mode part of Setup is complete, the computer cannot be restarted successfully to enter the GUI-mode part of Setup. Additionally, the computer may stop responding. You may receive an error message that resembles one of the following:
A disk read error occurred
Unable to load operating system
Error loading operating system
When you deploy a Windows Server 2003 sysprep image to a system, the system may continuously restart after you start the system for the first time. If you press F8 and then disable the "automatic restart" option, you may receive the following Stop error:
Stop: 0x000000ED (0X81F85678, 0xC000014F,0x00000000,0x00000000)
Additionally, if you view the disk in Windows PE 2.0, the disk may appear as "raw."
|Disk enumeration optimizations are disabled on certain Windows Vista-based computers that are using a hot swappable drive bay|
Windows Vista disk enumeration optimizations are disabled on certain Windows Vista-based computers that are using a hot swappable drive bay. This behaviour may cause some perceived decrease in performance on start times.
|Event ID 12 and event ID 57 are logged in the System log when you "hot detach" a removable drive on a Windows Vista-based computer|
When you "hot detach" a removable hard disk device from a Windows Vista-based computer, a Warning event that resembles the following may be logged in the System log:
Event ID: 12
The device device_name disappeared from the system without first being prepared for removal.
Additionally, if the disk is formatted by using the NTFS file system, a Warning event that resembles the following may be logged in the System log:
Event ID: 57
The system failed to flush data to the transaction log. Corruption may occur.
This issue may occur if the disk is "surprise removed." For example, this behavior may occur if you remove the disk without using the Safely Remove Hardware icon in the notification area to stop the disk first. This issue may occur even though the disk uses an interface that supports surprise removal, such as a universal serial bus (USB) interface or an IEEE 1394 interface.
|The partition that hosts Windows Vista may disappear if you use Windows XP to create a partition on a computer that has both Windows XP and Windows Vista installed|
