Ubuntu One :: Way To Get U1 Back To Original Unobtrusive Self?

ubuntu one takes like 30s to start all of the sudden (it used to be almost instantaneous on log in). This is an issue for two reasons: first is the fact that system performance is drastically compromised while ubuntuone-syncdaemon starts since it is accessing the disk as much as it absolutely can, which means that other programs also take forever to launch; second, when it finally does start, I am prompted to unlock the keyring, which interrupts whatever I am doing in a fairly annoying fashion and prevents the screen from locking properly if the computer is suspended.

While ubuntuone-syncdaemon is taking its merry time to launch, the status of the process is "uninterruptable," and an entire processing core is used at 100% with IOwait, as it is furiously accessing the hard drive.Is their any way I can get u1 back to original, unobtrusive self? Could this be indicative of a hard drive issue.
