A Microsoft engineer slammed Vista’s ReadyBoost feature as the source of a maddening bug, only to withdraw his charge the next day.
Whether or not ReadyBoost is to blame for the bug — which brings laptops to a crawl when resuming from sleep or hibernation mode — the problem remains a mystery for many who use Vista.
Microsoft engineer reports ‘Vista suckage’
In a July 7 post entitled “Vista ReadyBoost Suckage & Vista resume sluggishness,” Microsoft security software engineer Robert Hensing identified an apparent bug in which Vista can take several minutes to resume after a portable computer is put into sleep or hibernation mode.
“The disk just freaking thrashes and the HDD [hard disk drive] light stays on pretty much solid and the whole machine is pretty much unusable for about 5–8 minutes until the disk ‘settles down,’ ” he wrote.
During the sluggish resume, Hensing noticed that Vista was writing several hundred megabyes per minute to the Flash drive he used for his ReadyBoost cache. ReadyBoost is a new Vista feature that uses a USB Flash drive as additional memory, as described by Microsoft. Hensing discovered that his notebook computer resumed Vista in just a few seconds if he removed the Flash drive during sleep mode.
