As far as I know, the hdparm program does not allow you to scan for bad sectors. It only allows you to control if a hard disk does the bad sector management or not. This sounds dangerous, and I would not use ths manually.

The mke2fs command can check for bad sectors when you specify the -c parameter. If this parameter is found, it will start the backblocks command in the background (which is part of the programs that come with the ext2fs tools). You can run badblocks manually, but again, it has some dangerous parameters, so you should be very careful. If you for example specify the -w switch, the program will actually write to the sector in order to find out if it's bad. This of course will destroy what was in the sector before. So don't use this on an existing partition.

The command usually lives in the /sbin directory, which is not part of the search path of a normal user, and it's also not executable by a normal user. This means that you have to be root in order to run this program.
If you read the man page, it is however strongly suggested that you do not run this command in stand-alone mode. You may not even be able to tell what's wrong. The program was written as a companion application for mke2fs when used with the -c switch.

If you must run it, the following will most likely not damage your hard disk (but  I cannot giving you any guarantee!):

/sbin/badblocks -s -v /dev/hdaX

Just replace /dev/hdaX with the partition you want to check.
