Strange Spinning Circle Caddy in Optical Bay

[Magnakai]

Hi all,

i've been doing some testing on a rather large laptop for a few days now, and encountered something strange. i completely emptied all the HDD bays, and i am operating 1 system disk by SATA via a caddy in the optical bay.

navigating through windows, i noticed that i get strange 'interruptions' quite occasionally, even after the system has completely booted. well not really interruptions it's not really lag, but that spinning circle when windows is loading something. i only got fresh windows on at this stage, no other application software. just some diagnostics. all optimal hardware drivers installed. power plan set to high performance. disk set to write-caching.

this should not be happening? while i know it's not the fastest processor, it's at least a true 4-core i7 on 16gb patriot viper. my test disk is old and small (250gb) but at least 7200rpm and should not be getting these circles so frequently. RST reports drive is only running on SATA II but i think that's because of this HDD's low specs. HD Sentinel Pro reports Performance & Health both at 100%.

what do u think is the problem? do u think i need special firmware drivers for caddy? i always thought a caddy is just a fancy brace with an immovable plastic sata interface, and sata is just sata, going through the optical bay to the main pcie exchange on the motherboard.

any suggestions?

thanks
