5 minutes to boot if there isan USB drive

[Jeje]

Hi,

my Vista computer can takes more than 5 minutes to boot if I have an USB
hard drive connected.
if I unplug it before starting the computer then I boot quickly.

any idea?

Thanks.

Jerome.

Likely a BIOS option "Legacy USB" is enabled. This causes USB
devices to be mounted ( enabled ) prior to the Operating System
booting. Not all USB devices cause this delay. I had a Maxtor
One Touch USB that used to cause the type of delay you describe.

If the USB Bios is already set to DENY USB LEGACY then your problem
"might" be the actual drive. Many have some fast memory and the rest of the
memory is much slower.

Is your Flash Drive fast enough for Vista's Readyboost

The Big Marketing Lie on Flash Drive Performance

Gleaned from Newin.net
Windows ReadyBoost is a great technology, caching things on USB drives to
improve system performance, but Windows Vista insists on checking the drives
for certain speed requirements before enabling the feature. If you have a
USB drive that is just a hair to slow to beat the test, or you want to use
an external hard drive (slower speed, loads of cache space), Matt Rajca
posts at Channel 9 how you can force Vista to let you use ReadyBoost on an
unsupported device, whether it wants to or not :

1. Plug in the device.
2. Open the Readyboost tab on the device properties.
3. Select "Do not retest this device"
4. Unplug the device
5. Open regedit (start->run->regedit)
6. Expand - HKLM (Local Machine)->SOFTWARE->Microsoft->Windows
NT->CurrentVersion->EMDgmt
7. Find your device.
8. Change Device Status to 2
9. Change ReadSpeedKBs to 1000
10. Change WriteSpeedKBs to 1000
11. Plug in the device.
12. Enable Readyboost!!!!
