Two weeks ago I reloaded Vista Ultimate (32-bit) on a Dell Latitude D620.
The only significant change in the system is that I enabled BitLocker
Before reloading the OS I was using ReadyBoost on a 1GB SanDisk Cruzer
Titanium. Since the reload I've noticed that the ReadyBoost.sfcache file
will disappear after a while. The time between enabling ReadyBoost and the
cache file disappearing hasn't been consistent. Sometimes it's almost
immediate earlier today it took an hour.
As far as troubleshooting goes:
- tried switching USB ports
- disabled RB, rebooted, and re-enabled
- full-format and chkdsk of the Cruzer
So far nothing. As I'm typing this out I realize that I haven't tried a
different flash drive and will here shortly.
But has anybody else seen this happen? Any ideas on a cause?
