i overwrote the whole disk with ddrescue -f /dev/zero /dev/sdb.After one
and a half hours later it stopped with the message "no space left on
device" - i guess it indicates no problem ?
i also tried the badblocks program with -w option. It took a long time
5+ hours but did not report a bad sector.

I checked the seagate site and there is no firmware upgrade for this
model. On further googling, i found that seagate is only offering
firmware upgrades for 7200.12 model onwards.
Now to be absolutely sure, i downloaded the seatools program and it ran
a short and long test which both said PASSED.
Inspite of all these, gsmartcontrol shows the same.
What are the indications before a disk is going bad which a normal user
can catch with bare eyes and ears ?
