Also I'd simply get another PSU (or complete case) from Hong Kong. Likely the PSU wasn't a good one in the first place.

Most of the time, replacing the failed capacitor(s) will get the power supply working again. It's always worth a look, before throwing it away.
If the mains fuse has blown, check the bridge rectifier, then the chopper transistor, though if the latter has gone short circuit, often the controller chip will have blown too, and repair may not be worthwhile.
The datasheets normally give a typical circuit diagram - in my experience the whole power supply is usually very much like the typical circuit given in the controller datasheet.
Finally, remember that all a power supply does is give out voltage and current. One power supply can be substituted for another. In the case of your HDD enclosure, it's almost certainly a +5v and +12v supply at about 1 amp max. If you really can't fix it but still want to use the enclosure, you can cut off the output lead from your dead PSU and wire it up to another one, as long as it provides the same voltages.
Power supplies can be salvaged from other modern junk equipment. Of course, as Michael points out, these days HDD enclosures can be ordered very cheaply online. Sadly our throwaway society means it's often cheaper to order a whole new HDD enclosure from China instead of just buying a replacement power supply. But it's still fun to try and fix things!

That's not really relevant, because, whether or not I can repair the SMPS, I can access the HDD data by fitting it inside my computer. As it happens, though, there was no HDD in the external enclosure at present, because I had removed it at the time the SMPS died.

But what if there is data on drive and drive is expensive and a dodgy PSU fries the drive?
