I've never been able to find any Toshiba tools at Toshiba's web site, but I tried again today.
"Your entry doesn’t appear to be valid. Please double-check that your product is from the US or Latin America and try again."
I tried both "HDD1F15" and "MK1633GSG".
In any case the OP is already using the most appropriate tool for the job. The problem appears to be that the drive has "slow" sectors. If the data are important, the OP should boot to a tool such as ddrescue and clone the drive. Otherwise, if the OP wishes to test the drive, then a full surface scan with MHDD will identify any slow blocks and report their access times. That's something that manufacturers' tools such as WD's Data LifeGuard and Seagate's SeaTools will not do. Manufacturer tools appear to be designed to minimise warranty returns rather than providing a real assessment of the drive's health. They're just concerned with whether a sector is readable or unreadable, not how long it takes to read it.
The most obvious problem in the OP's SMART data is the raw value of the Reallocated Sector Count, namely 232 bad sectors. Neither Data LifeGuard nor SeaTools will report this number. IMO that's dishonest. It certainly is misleading, especially in Seagate's case.
Moreover, some drives, particularly WD's, record a number of SMART attributes which are not reported to the user. To see them, you need to dump the firmware and analyse the relevant SMART modules. I have written a tool that does just that:
Hidden SMART attributes in WD HDDs:
http://www.hddoracle.com/viewtopic.php?f=59&t=127&p=155Often I find that these hidden attributes have hit the threshold, which means that the drive has technically failed, but the user is never made aware of this.

Here is what a WD "engineer" has to say on the subject:
http://community.wd.com/t5/Desktop-Mobi ... d-p/525826That should tell you what really goes on inside WD's Tech Support. It's a very enlightening read, for all the wrong reasons.
As for a USB enclosure, don't bother, unless you wish to retain a failing drive for non-critical storage. The best way to test your drive is in situ with MHDD. MHDD accesses the drive directly, at the register level, without going through BIOS or DOS. You cannot get any closer to the drive than that, at least not with DIY tools. A Windows environment adds a huge amount of obfuscation, and a USB enclosure adds even more.
