Many computers give you the option to set a “hard disk password” along with operating system passwords and BIOS passwords. This is different from encryption — a hard disk password doesn’t actually encrypt your files.

From what I've read using Solid State Drives and drive encryption will wear the drives down quicker, and Truecrypt recommends not to use it on a SSD. Does using this HD password wear SSD's down less? I'm not too familiar with this HD password feature from manufacturers, my laptop doesn't have it from what I've seen. But if it was easier on an SSD I can see that being a good alternative, especially since Truecrypt recommends not using it on them... but if there is not less wear than I def. agree encryption would be the better option.

I'm also curious about SSD.
is more safer "hard disk password" on SSD?

If encryption writes/erases from the SSD, then yes, it would wear down the SSD quicker. I personally don't know exactly how encryption works, but if TrueCrypt suggests not encrypting an SSD, then at least TrueCrypt probably writes/erases from the drive. I don't know about other encryption methods, but I bet it's similar.
The article here pretty well spells out that there is no write/erasing to the drive with an HDD password, just a lock in the firmware, so yeah, this solution wouldn't wear down an SSD any faster than just using it normally. So yeah, in the case of an SSD, a HDD password might be better than encryption.

All of my SSD drives are encrypted. We will see I guess.
FileVault2 on the MBP and Bitlocker on my Windows 8.1u1 Enterprise.

There’s no real reason to use a hard disk password. Encryption provides much more security and is more convenient to use. Skip your computer’s hard disk password feature and encrypt its hard drive if you actually want to protect your files.
Well, there is a reason. There is a performance hit with encrypted files that is noticeable with platters. With SSD, it's not noticeable, but then it will result in faster wear.
If you don't encrypt your drive at all, then it's trivial for someone to remove your drive, mount it, and read the data off of it. Your Windows account password doesn't protect the data.
Therefore, the hard disk password is a decent compromise. No performance hit with some security. An average thief is not going to do forensic analysis to get personal data off your drive.
You can think of this analogy:
HD password = locking front door
drive encryption = locking every file cabinet in your house
no HD password or encryption = unlocked front door

This is what exactly happened with my Samsung notebook. I set a hard disk password in the BIOS and all out a sudden the hard disk refused to accept my password (I am really pretty sure I entered the exact password which I set in the BIOS settings.)
Actually I have a thread on the old HTG forum: http://www.howtogeek.com/forum/topic/forgotten-hdd-password-on-my-samsung-netbook
I made a lot of research regarding this problem of mine. But to no avail, until now still can't find the workaround to solve this problem (Most of the dead end are the corporate groups that offers this removal services but its very expensive and mostly international, too far from our place). The notebook is still functioning, I'm using a bootable USB with Zorin OS inside it, but you know this is really incovenient.
I hope someone here could maybe possibly know how to fix this,
