Hello Everyone,

I have a 500GB IDE HDD. I'd put it in a plastic bag, as I'm currently moving HDD's around. I took it out of the bag the other day and noticed that Pin 40 (Ground pin) had broken off.

Secondly Pin 39 appears to be shorter than the others. Or at least appears to be pushed further in. Is this correct? I don't believe it should be at all.

I've managed to get the data off, thankfully. But I don't really understand what either pins do. Is it safe for me to use?

My intention is not to use it, but I'd rather have a reason for not doing so. I'm also going to wipe the drive, before I dispose of it.

Thanks for your time.

Matthew :thumbsup:

Kind Regards,

If you can retrieve your data I would do so and abandon that hdd. If you have a dead IDE hdd you can cannibalize the connector from it and install it on the circuit board of the damaged one. It's tedious work as you will need to unsolder all of those pins from the circuit board.

Every other pin on an IDE connector is ground, one missing won't make a difference.

With a 40 pin configuration pins 2, 19, 22, 30, and 40 are grounds. The 80 pin configuration has the alternating ground wires, one for each data lead.

Pin 39 is a LED driver.

Id go with DC3's advice, since you say you have the data off, just toss it. Soldering can be a bad thing for a good portion of people, and its not to hard to get a great deal on 500gb IDE HDD's.

Thanks for the replies.

If not being able to fix it, what would be the technical reason for chucking it? Considering it is still working...

I'm trying to find out what the ground pin did, and doesn't do now.

Cheers for the advice.

Kind Regards,

There is no technical reason for chucking it considering the fact that it works fine. There are multiple grounds for redundancy and to minimize crosstalk between the data lines.
