The HD board is at least 2" narrower and quite a bit shorter.Quote:

turn over a bunch of hard drives, and open a bunch of Frisbee drives. it will explain itself. that is how easy it is.Quote:

There will be 40 pins on each board (Assuming they're IDE- Most will be).
The hard drive boards have more chips, though. A hard drive will need more controller functions than a CD Drive will.
The chips are the difference. Of course, you'll want the largest hard drive boards possible. ;)
Hard drive boards are the width of a hard drive and cd/dvd boards are the width of a cd/dvd drive.
Well, there's that too...Quote:

great answer...thanks for sharing your knowledge with us...thats what i was looking for
I'll sort them for you at $5.00/Lb.!!
this is a little bit off the topic but does anyone know what type of screw (the head) is in the hard drives? also, where to get them?
Yeah....that style screw head is called a ford screw. The best tool to use is a toxic bit in a drill or screw driver. I think it's a size T6 or T8
Ahhh....got to love spell check. **Torx ** bit
sry but my spoon is worn out. You need to do some home work. Google is your friend. (sometimes)
The screw heads for the motor are usually under the platters. Not always, though.
There are about 20 million different ways the platters can be attached, though.
you definately need some torx bits if you're gonna do any work with computers...sometimes they hide the screw heads under a sticker

The smaller harddrive boards are this same width too . But with more chips.
I found a nice cheap screwdriver set, yellow and black handles, for NZ$10. With the Torx bits, there's one size torx bit missing but I have only found that size screw once.
For that, I reground a broken drill bit 'backwards' (as a left hand drillbit would be) and unscrewed the screw by 'drilling it out' with that drillbit. It drilled a bit, then caught, then unscrewed the screw once the screw came loose.
You will probably find the same set at harbourfreight. They are mounted in a 'fan like' array on a cheap plastic backing.
Pozidrive bits, flat bits, torxbits
With experience you will find it easy to tell the difference. I find the color of the the HDD boards and CD/DVD boards have a marked difference along with the feel and overall appearance. So after a few hundred of each you sould be able to pick them out easily, I know I can. Mike.
they almost always hide them under the stickers. nowhere near sometimes for me... it's 99 out of 100. it's a warranty thing.Quote:

even if you have no trouble telling the difference, why handle them an extra time? into the proper bucket it goes the first time you touch it, unless you are do math on yields or something similar.Quote:

Exactly. I try to handle my boards one time unless they need more processing to increase their value.Quote:

i should have thought of that from the beginning but i was so happy taken those drives apart and seeing that gold that i just threw everything into a plastic storage container but now i'm facing my day of reckining...sorting them out
I know when i break down computers i have all my bins in front of me and each item goes in the appropriate bin. When it comes to hard drives or CD drives. i just toss those in separate bins and when i have nothing else to do or the bin starts to overflow i just pull those out and sit in front of the tv and go to town. Simple and easy and makes the process easy to see what i have instead of having stuff everywhere.
I also pull the small jumper on the plug in end and save them till I have nothing to do at nite.
Split them with wire cutter on the edge and look for the gold wire inside. A little adds up a little bit at a time.
