Fried three hard drives

By richardjcam ·
Bad day...

I was moving my pc innards to a new case. Everything was fitted, powered up: smoke. From the front, so I suspected a hard drive. Checked I hadn't made any shorts in the case etc. and tried again. This time Win 7 started up but THREE of the drives (five total) were not detected. Nor detected in BIOS. After switching around sata and power cables, and trying the drives in another PC and external HDD case, discovered the three drives had been damaged - none of these spin up nor are they detected. Freezer etc. methods will be tried on the drives to recover data, but Im also concerned about the cause so that I can prevent it from happening again. Suggestions? Power Supply or motherboard (both which worked fine prior to being moved over and work fine now with the surviving two drives in the new case)?


MB: Gigabyte P55-UD4PA (Rev 1.0) BIOS F14
CPU: i5 750
PSU: Antec ion2 460W
GPU: Sapphire Radeon HD4870
RAM: 2x2Gb G.Skill Ripjaws DDR3 1600 AND 2x2GB G.Skill Trident DDR3 1600

Surviving HDDs:
Samsung 1TB HD103SJ
Samsung 250GB SP2504C

Dead HDDs:
WD 750GB Caviar Green WD7500AACS
Seagate 1TB ST31000333AS
Samsung 250GB SP2504C

Any suggestions much appreciated.

Same thing happened -- mushroom cloud -- to the tech replacing a $3000 motherboard in my welding machine.

Ribbon cable, it turned out, was attachable either way.

So what did the welder do to

Trash the Circuit Board in the Welder?

Yep I know that they are trough but even still the people who make the welders know this too and design accordingly. Or should.

Business at the time

by santeewelding In reply to So what did the welder do ...

Thankfully, was in a trough back in the early 90s. I was down for a month. Took that long for a replacement MB from Appleton, Wisconsin (Miller TIG).

Meantime, I kicked back with my feet up and embarked on an intense course of study, all day everyday, with tomes I had always meant to read -- history, law, politics -- shooing away the few customers that did show up.

Seminal, it was.

Also, it propelled me into later courses on IT hardware, and software, and the people who populate the industry. The tech had to eat the cost of the MB. I made sure -- and, am making sure with my presence here -- that I have a clue about what's going on. I don't fancy eating $3000.

Did that with a power supply once

by NickNielsen In reply to Condolences

The mixing board in the college radio station main studio was dead one morning. No lights, no amplification, no nothing, but the passive circuits worked just fine. Ordered a power supply board, pulled the old one out, and inserted the new one, oriented the same direction. Powered up the board and POP! Ordered another PSU...and the service manual.

When it came in, I checked the service manual and discovered from the schematics that inserting the power supply backward was guaranteed to cause damage because the output and ground connections were in the same relative position on opposite sides of the edge connector. No wonder it popped! I also discovered that the boards used an arrow at the top left corner of one side of the board as the key indicator.

Before I inserted the new power supply, I unplugged the mixer and verified all the other cards in that board were inserted correctly; only half of them were. Installed the new PSU and we were back in business on that board.

We eventually found out that the late night DJ hadn't felt like going back to his room after he signed off the air one night, so he decided to see what was inside the mixer board. Being neither mechanically nor electronically inclined (but a damn good chef!), he didn't pay attention to orientation as he pulled each card out and reinserted it.

As he was the one who told us, we tried to bill him for it...the day after graduation. Bet you can guess how well that worked.

Only thing I can think of here

by HAL 9000 Moderator In reply to Fried three hard drives

Is if you used too long a screw on the HDD to hold them in place it could have gone through the case and damaged the Circuit Boards on the bottom of the HDD.

Only other possibility is the case itself is badly designed and causes the Circuit Boards on the 3 Dead HDD to touch the Metal Parts of the case causing a Short Circuit.

There really isn't much else that is possible under these conditions.

There are possibilities

by NickNielsen In reply to Fried three hard drives

I'm inclined to agree with Colin that the failure was an electrical one-off caused by a physical short. Your data is probably intact on the drive platters.

If you're very careful, you might be able to recover the data from the dead SP2504C by moving the controller board from the good one to it. You may also be able to find replacement controllers for your other dead drives at a local computer shop, or even (God forbid the price) from the OEMs.

Good luck.
