The drive is obviously fairly old, if it only has 156 GB.
For this kind of work, I prefer System Rescue CD
. Boot from the CD, and do both a SMART check with smartctl --test=long /dev/sda
(you can continue working while the test is going on -- note there's two hyphens before "test") and a bad blocks test with badblocks -c 10000 -s -v /dev/sda
. The badblocks command can take a while to run, especially if it does find bad blocks.
Once badblocks is finished, check the SMART results with smartctl -a /dev/sda
Windows alternatives are Speed Fan
for the SMART test and HD Tune
for the bad blocks test.
I've seen disks whose bad blocks were repaired by doing badblocks -c 10000 -s -v -w /dev/sda
. This destroys the data on the disk, but since you were planning to install Windows, you're obviously not concerned about the data.
