spinning up memory sticks.

I've only just noticed this happening, but its possible its been this way for quite a while. When I try to mount my cameras memory stick using a usb multi-card reader, it now prints this message..
sdd: Spinning up disk

waits a while, and then prints

.............ready
SCSI device sdd: 253888 512-byte hdwr sectors (130 MB)
sdd: Write Protect is off
sdd: Mode Sense: 00 00 00 00
sdd: assuming drive cache: write through
sdd: sdd1
Attached scsi removable disk sdd at scsi0, channel 0, id 0, lun 3

Did something recently change which could affect this ?

caveat: I've only tested this with a Fedora kernel so far, but afair, we don't patch anything which could affect this.
