Lenovo G500 - Intel Rapid Storage Technology" SATA disk on Controller 0, Port Unknown detected"

Question

Hi Folks,
I have a lenovo G500 laptop which i had purchased during thanksgiving vaction in 2013. The machine was working fine till June 2014 when I stated getting Blue Screen of death with error messages "irql_not_less_or_equal" The OS was windows 8.1. This created lot of problem while booting , the machine would not boot at all.
Along with this message I started getting this message "Intel Rapid Storage Technology" SATA disk on Controller 0, Port Unknown detected".  This message was coming very often.
I along with Lenovo support did all the things possible, like factory reset etc. Finally the machine was sent out to depot for repair in July 2014. They replaced the hard drive and sent the machine back.
I got the machine back on 22nd July and since last week ,ie, 14th July I have started to get the issues again. My IE and Firefox will suddenly hangon and the blue screen will appear again with same message "irql_not_less_or_equal" occasionally. Yesterday i started getting Sata disk message again.
I wanted to understand why this message is coming back along with blue screen of death. Is there some problem with Windows OS or hard disk seems to crash again?
Thanks in advance

hi Shailesh,
Welcome to the Lenovo Forums.
From this article, this is the IRQL_NOT_LESS_OR_EQUAL possible cause:
"This bug check is issued if paged memory (or invalid memory) is accessed when the IRQL is too high.
The error that generates this bug check usually occurs after the installation of a faulty device driver, system service, or BIOS.
If you encounter bug check 0xA while upgrading to a later version of Windows, this error might be caused by a device driver, a system service, a virus scanner, or a backup tool that is incompatible with the new version."
From your description, It's possible that the HDD or the RAM is faulty but it's also possible that it's a software (driver) issue -- which is the hard drive (SATA) controller.
To verify, I would:
1. Run a diagnostic on the HDD (via Lenovo's Storage Quick Test or via HD Tune)
   - http://www.hdtune.com/faq_1.html
2. Run a diagnostic on the RAM (via Memtest86+)
   - RAM - Test with Memtest86+
3, Read the BSOD dump file to see what file caused the crash
   - How to solve Windows 8 crashes in less than a minute
   - If the file is associated with the Intel Rapid Storage Technology Driver (SATA Controller), uninstall the software from the Control Panel > Programs and let Windows install a generic Windows driver.

If you get an error after running the diagnostic test, I recommend you contact Lenovo and report the issue.
