When you launch Adobe Flex Builder 3 after installing the web version of Flex Builder 3, you receive a “No Disk” error message.

Consider the following scenario:

• On a ThinkPad X300 computer that is running Windows Vista, you enable the Disable optical drive option on the Power Management tab.
• You leave the system idle for more than 10 minutes, and the optical disk drive turns off.
• You perform a suspend-and-resume cycle or a hibernate-and-wake cycle on the computer.

In this scenario, the computer’s optical disk drive is intermittently not displayed in My Computer or in Device Manager.

Consider the following scenario:

• You are running a Windows Vista-based computer.
• To provide additional space on the computer’s hard disk, you run a disk management program to expand the size of a logical unit number (LUN).

In this scenario, the LUN size is not updated after you run the disk management program. This issue occurs if you use a computer that includes GUID partition table (GPT) disks.

Note: A master boot record (MBR) disk does not experience this issue.

When you try to extend a volume using Disk Management in Windows Vista or Windows Server 2008, you may be unable to click Next in the Extend Volume Wizard.

Consider the following scenario:

• On a ThinkPad X300 computer that is running Windows Vista, you enable the Disable optical drive option on the Power Management tab.
• You perform a suspend-and-resume cycle or a hibernate-and-wake cycle on the computer.

In this scenario, the computer’s optical disk drive is intermittently not displayed in My Computer or in Device Manager.

Consider the following scenario.

• You are running a Windows Vista-based computer that has more than one hard disk.
• Windows Vista is installed on the primary hard disk.
• There is a partition on the secondary hard disk.
• You disable the secondary hard disk.

In this scenario, the computer must be restarted. This occurs even when no files or folders are open on the secondary hard disk when you disable it.

The first time you launch an Adobe Flex application in a new workspace after installing Adobe Flex Builder standalone from DVD, you may see a “No Disk” error message similar to the following:

You connect an external hard disk that is based on the Institute of Electrical and Electronics Engineers, Inc. (IEEE) 1394 standard to a Windows Vista-based computer. However, the external hard disk is not detected.

This symptom occurs on dual-capability external hard disks that can be connected by using an IEEE 1394 connection or a USB connection. However, this symptom only occurs when the external hard disk is connected by using an IEEE 1394 connection.

Windows Vista disk enumeration optimizations are disabled on certain Windows Vista-based computers that are using a hot swappable drive bay. This behavior may cause some perceived decrease in performance on start times.

Microsoft released a slew of updates on Tuesday, which extended beyond security related fixes. They also made available the Release Candidate for Service Pack 1, which among other things, is said to improve performance when copying and moving files. If you’re running Vista on your production machine, you probably won’t want to install SP1 RC, as it’s not quite ready for prime time. You can now get the disk performance improvements without installing SP1 RC through an official Microsoft Update that was also released on Tuesday. Keep reading →
