Alguns trechos do texto:
Description
The following issues may occur on Windows Vista* with a supported Intel® RAID controller hub:
- Timeout errors reported by iastor or iastor(v) in Microsoft Event Viewer
Cause
Various desktop Serial ATA devices such as hard drives and CD/DVD drives have been reported that do not comply with the Serial ATA Link Power Management (LPM) device specification and display erratic behavior when LPM is enabled.
Solution
Install Intel Matrix Storage Manager version 7.5 or later. These versions workaround this issue by disabling Link Power Management (LPM).
If you are experiencing installation issues, you can also use one of the following additional workarounds:
- If available, install updated firmware for the device.
- Attach the device(s) to ports 3-5 on the Intel® 82801HR/HH/HO I/O controller hub (ICH8R) or port 3 on the Intel® 82801GR/GH I/O controller hub (ICH7R)
- Switch to IDE mode in the system BIOS.
Note : This change will disable RAID functionality. Contact your BIOS manufacturer for instructions on how to switch to IDE mode.
