USB2.0/eSATA Enclosure for 1TB Samsung F3

[bremen1874]

I just tried to install a 1TB Samsung F3 into an Akasa Integral P2 eSata/USB 2.0 3.5" enclosure I had spare.

Unfortunately it looks like the Akasa PSU isn't supplying sufficient current when the drive tries to spin up. You can hear it trying, but it never quite manages it. I've tested the drive on a standard PC PSU and spins up okay.

The Akasa PSU provides 1.5A on the 12V rail and 2.0A on the 5V rail. According to the Samsung site the max spin up current is 2.3A but it doesn't specify how that's split between the 5V and 12V rails.

Has anyone else run into this problem, and was there a fix that didn't involve buying a complete new enclosure?

Even if I wanted to get a new enclosure the PSU specs don't seem to be quoted so it would be a bit of a lottery.

Thanks.

Quick update.

I found that the PSU for a D-Link DNS-323 uses the same connector and pin out but provides 3.0A on both rails.

With this PSU the spin up problems disappear. Unfortunately this PSU isn't spare in the long term as it belongs to a client.

I've dropped Akasa a line on the off chance that they can provide a higher capacity PSU. I'm not going to hold my breath.
