RAID Drive becomes unavailable

I am running Win 10 Pro 64 bit. I have a RAID drive set up on my F drive. When I turn on my system it runs fine and is available, but after the PC sits idle for some time none of the files inside of it are available. In My PC I can still see the F drive listed, but I cannot open any of the folders/files inside of it. Any suggestions? Currently my PC is set to never turn off monitor/never put PC to sleep. Thanks in advance for any help you might offer.

Tell us about the RAID.

What level is it. Specifying RAID without the level is meaningless.
Is it software RAID, implemented by the motherboard, or a separate controller.
What drives are being used.

Sorry, it is an external RAID array. I can see it in device manager/disk drives/ HzW RAID10. I have it as my F: drive

I believe that makes is a separate controller.

It sounds like power saving mode , the Drive has gone to sleep or been turned off to save power, either in the Power Scheme under Hard-drives or perhaps at the Controller if you allow Link Power Management ,which you may also see in your Power Scheme.

External Drives Hibernate too ....

I have the same enclosure actually but the non raid version but have it running on USB3 instead of esata as my MB's Esata ports didn't do port replication properly , so I could only see 1 drive.

how old is it ? I know for mine there was a firmware released for a HD spindown issue But that was 3 yrs ago I think ?

are you connected to MB or Mediasonic's add in Esata Card? it may need a newer Driver version ?

It's not on the Product page but on the Forum there is a SW download for the onboard Raid Controller so you can manage it http://forum.mediasonic.ca/viewtopic.php?f=112&t=979

I still suspect a power/hibernation issue , did you disable link power management too ?

are you set for s3 suspend in the Bios?

I am connected to my MB through eSATA. I have never updated the firmware on it and have owned it for more than 3 years. Where did you see the firmware update link ? I looked at the post, but the download links were no good. My firmware is V0.958 [11/17] Do I need it? I couldn't tell from the instructions as they don't mention that firmware.

I have a P8Z77-V PRO motherboard, and I am not sure if it supports Port Multiplier w/ FIS-based switching. I can just see the one drive, but that's what I thought would happen with the RAID 10 setting. Should I change the setting from eSATA

The link was to the JMicron Raid Controller Software for your ProBox , not to the Firmware which is in this post, but you need to email them for it at rma_east AT mediasonic.ca. (replace the AT and spaces with @)

Note: If your enclosure does not have firmware version
0.20.03.00.04 on it. or the serial # of your enclosure starts with ***13 *** 14
(i.e. FEB13, APR13 etc..) Do NOT USE these Firmware Bellow

NOTE: Not for Rev. 02 or Rev. 03 enclosures

are you sure about that firmware version ? What revision is the ProBox ?

Your 4 drives would show as 1 as you are using Raid , unlike my non-raid version , so I just used USB3 since I saw no advantage to esata , and I would of had to buy a esata Card with Port multiplier capability to get it.

Try it with USB3 and see if you have the same issue.

That was the firmware version I saw in the JMicron Raid Controller Software that you sent me earlier. Maybe that's just the software firmware version....

The serial number on the back is FEB 13***** So that means I do not need to update the firmware, right?
