Fixing Windows 7 can't return from stand by (sleep) or hibernate when Readyboost is used

It has been almost a year since I moved to Windows 7, and the only problem I find with Windows 7 is Windows 7 often failed to return from Standby (Sleep) or Hibernate when Readyboost is used.

I waited for an update from MS, and they did not came after a year.  Perhaps that is due to Microsoft never actually experiences this issue.  The solution is very easy actually, and I should not have to wait it for a year but apply the solution right away: formatting the USB device in exFAT.

I always format my USB device in NTFS and combined with my HP dv2 laptop the computer is often can't resume from standby or hibernation.  I knew the problem lies on the USB driver (or perhaps hardware?) for quite a while as the computer is pretty often announces that one of my USB device is plugged into USB 1.1 port.  This happens usually after the computer resumes from Standby or Hiberate.  But things got worse when the drive is formatted in NTFS.  I'm unsure what made NTFS partition more problematic compared to exFAT, however these are my diagnostics 

  • With a Readyboost drive attached, the computer took a long time to resume from standby or hibernation.  Probable cause: USB device stop working and reverts to 1.1 and shuts the Readyboost down.
  • Then Windows can't find the cache it was looking, therefore Windows kept waiting.
  • With complex NTFS format, it is even harder for the Windows to resume from standby, and then the OS surrenders and restarts.

There are two solutions to this problem.  First, remove the Readyboost at all which I did not wanted that to happen, or try other ways.  Second try to change with simpler file system.  Then I just follow my instinct to format the partition as exFAT, since exFAT is a lot simpler compared to NTFS but supports larger drive and file compared to FAT32.  Large file support is the important thing, as Readyboost requires large file support.

To change into exFAT partition, first you can open your Start Orb, and choose Computer.  Then right click on the drive you wanted to format with exFAT and choose Format.  Please note, by formatting your drive, you will loose every file, data and everything on that drive!  That will bring this form:


Using exFAT, I've never been able to experience this issue, or even when the USB drive fails.  The Windows just resumes after quite a while.  However, my data security will be at stake, since exFAT is not as secure as NTFS.

FYI, Readyboost in an exFAT partition is faster compared to Readyboost in NTFS partition.

That's all folks, I hope this all helps!
