Drive is intermittently disappearing


My 2017 ASUS computer running Windows 10 is such that my E drive is intermittently disappearing. I've checked it with chkdsk and it's fine. I've also checked it with the defragmenter and it isn't fragmented at all. 

To get the drive back, I have to reboot. Sometimes I can do Restart. Other times, I have to Shut down and then restart. 

When my E drive disappears, I get this message:

Intel Rapid Storage Technology
SATA available disk: Removed

I have a C drive, an internal D drive, an internal E drive, a CD-ROM F drive, and an external G drive. 

Sometimes when I plug my phone in to a USB port, it appears and disappears every minute or so. Which seems like a similar problem only faster. I don't think the E drive ever reappears, however, until I reboot.

Helo JimAndrews,

Thank you so for the additional information provided.

Based on the description and after checking the reports, I don’t consider that this behavior is directly related to the Rapid Storage Technology Software. 

This could be more related to the storage device or even the SATA controller of your board.

In this situation, I would recommend checking with your computer manufacturer to make sure that you have the latest SATA controller and check a possible hardware failure of the drive.

Please check the following link to check your Computer Manufacturer Support Website.

That being said, we strongly recommend checking with them and hopefully the issue will be resolved.

If you need any additional information, please submit a new question as this thread will no longer being monitored
