Re: Old HDD discussion
I attempted reformatting to see what would happen. The format process seems to be stuck at 20%. I'll swap the master/slave positions of the ST380011A and ST3120026A to see what happens.Comment

Re: Old HDD discussion
Done. Nothing seems to have changed much, except that the pending and uncorrectable counters on the ST380011A have gone up another 3.Comment

Re: Old HDD discussion
I found an option to erase the drive in HDDScan. I started it for the ST380011A and will see how it goes.Comment

Re: Old HDD discussion
It might be "healing" itself. The pending and uncorrectable counters have reset to 0 and the reallocation counter is unchanged. Although the ST340014A is dead, maybe this one will survive.Comment

Re: The aftermath
Scratch that. The pending and uncorrectable counts are up to 90 and the reallocations have gone from 26 to 30. The runtime is 39,473 hours. Looks like this one has had it.It seems fine now.
At least the ST3120026A is still hanging in there.Comment

Re: Old HDD discussion
As it happens, I have another ST340014A with a broken ceramic capacitor (the rest of the board seems okay). Measuring that position on the ST380011A showed it to be +3.3V. My plan in mind is to take the capacitor from the same position on the dead ST340014A. But that's for later...
Also, I don't know how bad this is, but I discovered that the 7200.7 PCBs originally had three small inductors which were later (after October 2003 but before February 2004) replaced by 0Ω resistors.Comment

Re: Up to 10,000RPM
One word: Understatement....the Raptor is louder.
Sure the ST3120026A is not the quietest drive ever but it's far, far quieter than that Raptor is when seeking. The WD800JD-00LSA0 (which should actually be called a WD800JS as it has SATA 3Gb/s support) is quieter again and has the same access time as the ST3120026A. I can't get AAM to work on that Raptor, so any plans of using it in my main system go out the window.Comment

Re: Old HDD discussion
My main hard drive is a Seagate. I can't remember the model, but:
*Can't remember where I got it
*160 GB capacity
*7200 RPM
*1 platter
*SATA II (3 Gbps, but only running at SATA I/1.5 Gbps because my motherboard doesn't support faster)
*Made in 2009.
*Main system drive, 30% full.
Seagate ST-157A-1
*Bought for $50 on eBay 2 years ago
*3(?) platters
*42 MB (not GB)
*IDE
*PIO Mode 0 only
*Stepper motor for seeking
*Probably from about 1990
*Cat landed on it while running with the cover off, still worked until it happened a second timeLast edited by cheapie; 04-22-2013, 11:49 AM.Comment

Re: Old HDD discussion
I'm guessing your main drive is either an ST3160813AS (7200.11) or ST3160318AS (7200.12).
The ST-157A is indeed a 3-platter drive, according to the Seagate Desk Reference. There's also a 2-platter 30MB model (ST-138A).Last edited by Shocker; 04-22-2013, 11:03 PM.Comment

Re: Old HDD discussion
What's more, a set of tests I just did in HDTune shows that if you short-stroke the ST3120026A to 37GB, it only falls short of the WD360GD-00FLA1 by about 1ms. So I can only say 3 words about that Raptor: Not worth it.Comment

Re: Old HDD discussion
In fluid-dynamic bearings (used by Seagate drives since the Barracuda ATA IV) there is no solid contact between bearing surfaces in-motion. As I remember, FDBs contain an oil circulated by the rotation and grooves in the bearing surfaces. The shaft entry point is not sealed - the oil contains magnetic particles and the casing is magnetised.Comment

Re: Old HDD discussion
That would explain why old hard drives are so noisy then - must be ball bearings.
I'd like to know why seeking gets louder with age though. It even seems to apply to old drives too - the self-test on that one ST-251 that had never been used was quiet, and then you have more used drive that sound more like whhhhiiiirrRRRRrrreeEEEEEeeBANGBANGBANGerrrrrrrrr...Last edited by cheapie; 04-23-2013, 08:21 PM.Comment

Re: Old HDD discussion
Correct.That would explain why old hard drives are so noisy then - must be ball bearings.
Head assembly still uses ball bearings. Fluid-dynamic bearings can only sustain rotation in one direction and rely on the rotation to circulate the oil.I'd like to know why seeking gets louder with age though.

I thought I'd throw out some of my personal experiences in the last 12 months with Intel iMacs, 2.5" SATA SSD drives and Fusion drive data recoveries.
As a backgrounder, Apple never fitted a 2.5" SSD's to these iMacs. Apple's SSD option was a system of 32GB NVMe blade drive (NGFF connector) and Seagate 1TB 2.5" HDD, married together in software to become a Fusion drive. Non Fusion systems have just the 1TB Seagate HDD.
So, the most common reason an iMac comes across my bench is because it's either ridiculously slow, or it fails to boot at all. The most...12-18-2024, 10:34 PM -
Hi.
I am starting to learn about UEFI BIOS.
At the moment I have Lenovo laptop with bad BIOS.
I tried to clean ME region and transfer EC region from a known working BIOS, but the laptop does not POST (just fan spin).
So there is something else bad.
If I flash a know working BIOS, the laptop POSTs and boots into Windows.
But the problem is, that the serial numbers, Windows key, and every thing else is from another laptop.
Where do I start to transfer the S/N, Windows key and other information from one BIOS to another?

Yes I am the idiot that paid monthly for all these years. I found a broken Tivo HD XL with lifetime service on eBay for $40 (Tivo 3), I bought it, it was a bad power supply, I re-capped it, good as new. So the plan was to cancel Tivo 1 and use Tivo 3 in it's stead. So I... -
