Ok. What I did find most interesting, after some painful googling is:
http://scottstuff.net/blog/articles/2005/01/08/anatomy-of-a-drive-failure

It is of course anecdotical, but interesting. Basically it seems that
the seek_time_performance stuff is more or less noise, at least when it
oscillates.

However those lines I found in his opinion seem more worrisome:
Nov 21 03:52:23 voynich smartd[7451]: Device: /dev/sda, SMART Usage
Attribute: 195 Hardware_ECC_Recovered changed from 253 to 252
Nov 21 04:22:23 voynich smartd[7451]: Device: /dev/sda, SMART Usage
Attribute: 195 Hardware_ECC_Recovered changed from 252 to 253

what do you think about?

I already have looked for a new hard drive, and tonight I will launch an
extended self-test.

By the way, for the new HD I found those two interesting:
1)Hard Disk 320 Gb Western Digital WD3200KS, Sata II 300, 7200 Rpm, 16
Mb Cache
2)Hard Disk Hitachi 320gb HDT725032-VLA360 S-Ata2, Ata 300,7200rpm, 16mb
Cache, Rohs	

I always heard good about Western-Digital; the WD drive is also the
least expensive so I'd choose it. However any advice is welcome.
