This sounds interesting. i think i will try this out over the weekend, just  
for the heck of it! Just out of curiosity, what is the reasoning behind this?

i found this document from Corsair through Wikipedia 
(http://www.corsairmemory.com/_faq/FAQ_flash_drive_wear_leveling.pdf). It talks 
about wear levelling, and at the last paragraph:

Will my Corsair USB Flash drive last more than 10 years?

Yes. All Corsair flash drives are built with memory components that can handle 
AT LEAST 10,000 write cycles; typically they will handle an order of magnitude 
more than this. So, this means that in order to exhaust the drive in ten years, 
one would have to write to EVERY BLOCK in the device about 2.7 times per day, 
every single day. We simply can’t conceive of such a usage scenario; this would 
mean that on a fairly typical 8 GByte drive, one would need to write over 21 
GBytes of data to it every day for ten years! USB flash drives simply are not 
used in this way.

If one thinks he or she might actually try this, we suggest buying a Corsair 
Flash Voyager GT or a Corsair Flash Survivor GT USB drive. They are built with 
components guaranteed for 100,000 write cycles. With these, one can write over 
210 GBytes of data to the drive each day, for ten years!

i think i may get one of these Corsair drives! Based on my usage, it should 
last at least as long as the portable hdd.


Just another update, this morning, i tried plugging in the USB hdd again 
(without trying the freezer technique yet), and it was detected! So i started 
copying out the other stuffs as well, and it managed to do that, but ran into 
the same previous problems about halfway through. hmm...



Thanks and Regards,
Edwin
