Water spilled on drives. Still ok??

I had carelessly left my little two bay drive enclosure next to an low end table. My drive enclosure had its cover off and I had left a glass of water sitting on the table above. As nature's laws work, I knocked the glass over, spilling about half of the water on the table which then spilled over the edge of the table onto the drives waiting below.

After the momentary shock of realizing what happened, I moved the open enclosure away from the table and ran for paper towel. The drives were not soaked, but the top drive (there were two in the enclosure, one above the other) which was new and without files received a shallow puddle of water. The backup drive below received much less fortunately, but still had wet spots. The bottom of the enclosure with its power supply was also wet as the water from above dripped and trickled down.

I turned the enclosure so its rear end was down and the water would drain off the label side of the drives where most of it sat. This also kept the internal part of the PS from receiving any more water.

I then toweled everything down carefully as the fear and dread set in. Tonight, after about a week of doing nothing, I gathered the courage to plug the drives in and test them (Seagate, 1TB). Both worked fine and made no unusual sounds. All my files were accessible on the backup drive. The PS of the enclosure gave off no odors or smoke indicating shorted or water damaged parts.

My question (after all the above details) is, would a windows bad sector scan uncover any damage done? I ran the test on both drives and received no notices of bad sectors.

My other question is, if this test is not sufficient to determine any damage, is there any test or tests that would? I'm kind of in limbo as to what to do because the water exposure was not good, but maybe did not get into the platters to contaminate them.

I don't mind the idea of spending on a new drive, but it may not be necessary. Or is it better to avoid taking any further chances?

Thank you.

Solution
In the future, you can use silica or rice as a desiccant. Just pour either into a bowl, bury the electronic and this will speed up the drying process

Should be fine. If it was just water, it would of dried under a week. Remember, the sector part of the drive is sealed so that air/dust can't get in it. If a single speck of dust hits a disk, the drive could be destroyed. So I doubt any water got in there. The only place of concern would be the green circuit board on the back of the hard drive. As long as that was dry, I can't really see water doing much damage.

Thanks for the replies. Two things I neglected to mention are:

1) The power was disconnected to the enclosure

2) The drives and enclosure sat without use for over a week.

About water getting on the circuit board side, a little bit did - maybe a few drops on each drive. I got them off carefully with paper towel.

Both drives ran for about 8 hours yesterday as windows scanned the surface and reported nothing back. Maybe I should check the logs, but all of my files are there and open normally.

My only concern now is down the road. There's always the possibility some minute amount of water got into some crevice and weakened a part or crept inside the drive.

To reiterate my original question, does anyone think that the windows surface scan could reveal any damage or potential damage?
