USB3-SATA-UASP1 Sleep and Large Volume Firmware Update

This article is no longer relevant. Please see our firmware update page here.

Customers purchasing the USB3-SATA-UASP1 can take advantage of a firmware update with the following features:

  1. Improved support for 512e “Advanced Format” drives 2 TB and above.
  2. Spin down disks after 10 minutes of inactivity, resume on access.
  3. Spin down disks on system sleep, resume on system wake.

Firmware version 121026910000 avoids drive sleep and spin down to eliminate issues with inaccessible volumes, however customers may prefer the sleep features available on firmware 130107917d00.  Almost all units of the USB3-SATA-UASP1 that have shipped to date already have this update applied.  Only if you are noticing that your drives stay running after your system sleeps or during extended (over 10 minutes) periods of inactivity is this update relevant.

For OS X users, please note that a Windows PC or Virtual Machine (VM) is required to update- updating firmware on the USB3-SATA-UASP1 is not supported for OS X.  Mac users can email to make alternate arrangement if they are unable to access a friend, neighbor, or library Windows PC to complete this update.  Again, please note that this update is only relevant if you are noticing that your drives stay running after your system sleeps or during extended (over 10 minutes) periods of inactivity.

    The article doesn’t mention where to get Firmware version 121026910000 if customers prefer to not have the sleep features. Could you please provide that link? Thanks.

      Hi Steven-

      Thanks for posting!

      Because it is not recommended for most users to disable drive spindown, we do *not* distribute this firmware publicly, however we’ve emailed you a link to download it in private. Any other users interested in firmware 121026910000 can email

      Best wishes-

    Is the drive spinning down after 10 SECONDS of inactivity one of the “FEATURES” of this firmware. I am using this with my Plugable USB 2.0 dock on Windows 8.1 Toshiba Encore and the drive goes to sleep after 10 SECONDS, its ridiculous.

      @ZIM I had the exact same 10 second spin down problem with Windows 10 and Surface Pro 4. Tried to fix it by going to the Windows Power Options Advanced settings, but there was no Hard Disk or USB settings options, like there used to be in Windows 7!

      Turns out, they are hidden by default, and can be turned back on using this Regedit tweak:
      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power, then change the value of the CSEnabled key from 1 to 0 and restart.

      Then in (Power Options/Advanced settings) I set:
      Hard Disk/Turn off hard disk after/Plugged in: to never
      USB settings/USB selective suspend settings/Plugged in: to Disabled

      Now the drive only spins down after the 10 minute interval controlled by the docking station. I don’t know if I needed to change both of those. Maybe just one would have done the job.

    Is it possible to have the firmware so the drive just goes to sleep as per windows power settings, sleep, shutdown, idle etc. Instead of the built in 10 minutes?

    • Gary Zeller Reply

      Hi Dale,

      Thanks for posting the question!

      At this time there isn’t a way to have the enclosure pass through a spin-down request per the Windows power settings.

      I’ll add it to the suggestions list and we’ll explore this possibility during our next firmware upgrade cycle. If anything changes regarding this, we’ll certainly put up a blog post about it as well as update the information on our hard drive dock firmware update page:
