    Portable HardDrive "Corrupted and Unreadable"

    It's a superb value, no doubt. However, to use it on customers' drives one needs the professional license, the price of which is $95 USD (still a terrific bargain!).

    How do you organize donors?

    Same here. For organization, I built a Open Office database app to key in donors, with an auto-incrementing inventory ID field and fields for typical match parameters. Drives are stored in storage bins, organized by Brand then ID. Works for me.

    Best place to get these ?

    Mouser has some that may be suitable (although not with that part number) and more quickly available. Where did you get that part number?

    Which tools do you use to check scratches on the platters?

    I have seen a video made using a tool prototype for inspecting between the platters and it seems to work really well. I'll inquire about permission to post it. Permission granted (Thanks, Nikola!). Here is what the tool shows, inspecting a scratch between platters.

    Particle Counters

    Thanks for the tip, Nuno! That was an excellent price, so I bought one. I'm pleased to say my clean chamber is at least Class 100. It reached that reading in about 3-5 seconds; it's very responsive meter! :mrgreen:

    JpegDigger

    I just used Disktuna's JpegDigger to extract JPG files from corrupted NEF files and it did a terrific job. It's freeware and did what several other programs I tried couldn't do. Files recovered from a drive image looked perfect in Nikon's View-NXi but when they were exported as JPG/TIFF or...

    Cleaning HDD Heads & Platters

    I tried that a week or two ago and the head got so dirty it could not be cleaned, even after two sessions in the UC with 99% IPA. The top surface of the platter ended up quite a mess and my donor was a write-off, which makes me hesitant to try that again, unless I use dead heads. :( Here's...

    Seagate UltraSlim (Rosewood)1TB and 2TB Technical Reviews

    I've solved the comb-falling-out-while-examining-heads-under-the-microscope issue, with a paper clip. LOL Works really well. I bent the clip so the ends are parallel and just a bit closer together than the width of the comb+actuator arm. The lower portion fits between the actuator arms and...

    Seagate UltraSlim (Rosewood)1TB and 2TB Technical Reviews

    Sam, in the case I mentioned, the HDA connector was in place and the comb just barely touched it but it didn't provide enough of a block to allow pushing the comb between the actuator arms. It just kind of tipped the comb, IIRC. Anyway, I'll be interested to hear if you find an idiot-proof...

    Rosewood PCB swap to test HSA compatibility killed donor?

    Ha, mystery solved! When I re-sealed the drive with Kapton tape after the RnR, I accidentally covered one spindle motor contact. No wonder it wouldn't spin up. Cleared that and it spins up fine. Phew! Thanks to Jol for the suggestion to try it with the HDA connector isolated. It was after...

    Rosewood PCB swap to test HSA compatibility killed donor?

    Working on my first Rosewood case and swapped patient PCB with donor HDA to see if donor would spin, implying HSA would likely be compatible. That was probably foolish, given the Rosewood tech nightmare. Anyway, the swap seems to have killed my donor, as explained below. Anyone else tried...

    Seagate terminal access -- timing of read channel shorting

    I have a Grenada (ST2000DM001 9YN) with a media cache problem and I'm finding it impossible to get F3 T>, no matter when I short the read channel. I've tried shorting immediately before "(P) SATA Reset" and immediately after that, but no joy in either case. Tried holding the short for 5 - 10...

    Particle Counters

    I received this particle counter yesterday but it came with no user guide. At the moment, I am unsure of the units of measure in the "USA" display. I made a few measurements in my clean chamber and on the desk beside it, and noticed that the values varied considerably over time, so I took...

    backblaze drive stats q2 17

    I'm confused at how they came up with such astronomical failure rates for those Seagate, with the figures provided, but I don't doubt them. No doubt they are projecting failure rates on a daily basis, rather than the quarterly results shown.

    7200.11 Platter swap - tape method

    The practice drives were all 7200.11s (as was the patient), but 500Gb vs 1.5TB. The practice drives(*) all had issues but could at least calibrate and scan a few million LBAs before the swap. With the patient drive, it clicks as if it's almost going to calibrate but gives up. (I'll try to...

    DIY Read Channel Shorting Tool

    I finally got fed up trying to short read channel VIAs using tweezers while madly hitting Ctrl+Z, so I just made myself a shorting tool. No way I was going to pay 35 Euros +VAT + S/H ($72 CAD) for a ready-made tool. Ten spear-pointed pogo pins cost me $22.24 CAD and 5 tactile push buttons cost...

    7200.11 Platter swap - tape method

    Hi Amarbir, I'll have to make a video and post it later. BTW, the platter swap went without a hitch but the drive clicks. Swapped heads from a perfectly matched donor (19 days apart) but it too clicks. I forgot to transfer adaptives, which I'll do and try again. It could also be platter...
