3 questions about external enclosure & advanced format drives:
I just got a 750 GB WD Black 2.5" (mobile) -WD7500BPKT- and I want to use it in this external USB3 enclosure -http://tinyurl.com/c5qbuzl. I'm wondering if I can use a standard USB3 cable, or if additional power is needed. The enclosure comes with a "Y-cable", which is double-USB to a mini-USB.
The enclosure has a note: "CAUTION!! When using USB 3.0 interface mode, external power is needed when HDD consumes power over 900mA".
Is this the power spec I'm looking for? Does this mean it draws 1150mA, exceeding the capabilities of a single USB3 cable? If so, can I use the included Y-cable, or must I get the power supply accessory from the maker of the enclosure?
> Question 2: This is an Advanced Format drive (http://www.wdc.com/wdproducts/library/WhitePapers/ENG/2...). I'm wondering if I need to run the special alignment software, for compatibility between machines (will be using with clients). For example, if I format it on my Win 7 machine (AF-ready), will it be usable on a client's Win XP machine?
> Question 3: Will alternative allocation unit sizes work with an AF drive, or must I stick to 4096? I believe there is a difference between sector & cluster size, & I'm not sure whether this is even relevant. I personally will stick with 4096 for now, but I sometimes assist folks with workstation setups, who might be interested in a larger allocation unit size.
