IT developments – continued (my own stuff)

Internal drive that’s been in my possession the longest
Did do a lot of disk-checking and a “file repair” on the internal HD that is still alive. Did not attempt the SeaTools “repair option” as it does not seem necessary at this point. That PC also seems to have power supply issues to do with USB ports, I think. May need a more powerful power supply, not an uncommon issue in older computers. (No, am not gonna bother.) The HD seems to have 6 bad sectors at the moment and it passed its recent DST (after failing it a few times), so that is not too bad. Will do some more stuff in a minute, just to see if anything has changed. Will also do a good clean in the case soon. 

(Also, it has two easily accessible USB ports from which the connectors slip much too easily, which I don’t like for external HDDs. Am gonna do a search on that issue in a minute as I have no solutions for it and there may be an easy fix. Update: Oh, LOL. A screwdriver to move those pins a little. OK. Will do that when I give the inside a clean.)

Internal drive that’s been in my possession the shortest
Other than take a look at how it’s sitting in the case, I haven’t done a thing with the HDD yet that seemed to have between 400 and 500 years of operation and that seemed to have failed big time. Came as part of a refurbished computer and I guess I simply lucked out with that purchase. (Though you never know with these “hardware heroes” around, hah hah.)

External drive
I’ve removed some screws to get the external HDD entirely out of its case. I can see why SATA bridges (the little plugged-in thingy on the right; see first photo below) are an easy point of failure – so flimsy – but that does not seem to be the problem here. Also, nothing looks funny about it. The chances of it having been loose are close to zero; I had to remove 6 screws after all.

That as much as I can do at the moment (take the thing out of its enclosure). I could plug it in again and see what it does, but there is no point at the moment.

 

Below are some photos of my home-made clean-air compartment. It does not photograph well, but I admit I barely made an effort. Has a HEPA filter type vacuum bag on the right and an opening for a vacuum cleaner on the left, so that you can suck air with dust out and filtered air in. At least, that is the idea. But the main point is that it is very hard for dust to get into this compartment so when I open the drive up, I will do that in this compartment. Wouldn’t it be cool if I eventually manage to get enough data off this thing in my DIY fashion? I’ve done this kinda cool stuff before and I tend to be pretty good at doing things considered impossible (in the sense of hard to achieve), so, we’ll see.

  1. Okay, am going to try one more thing before I open it up. What if… I am dealing not with a failed but with a failing SATA bridge? Theoretically, anything is possible. Since I have no way of ruling that out, I am going to have to try that before I open it up as that of course would entail some risk to the drive. The drive still wants to do stuff, every once in a while, making me think that it could even after all be a bearing/spindle issue – that it is spinning but not fast enough and that viscosity of lubricants plays a role, hence temp – and every once in a while it shows itself a little bit (not on the screen but in HDD software). It’s even now given me its model number and serial number but that is as far as it will go. (It would be nice to know where that serial number is stored on this drive. Could be the platters, could be the PCB.) It does not know what kind of partition it is and it shows as unallocated space. So my guess is that it is on the PCB, but if that is the case, then maybe the SATA bridge is indeed the culprit.

    The serial number seems to indicate that this HDD has only one head? Hmmm. (No, possibly 4.)

    None of this was necessary, you folks in Portsmouth. This was all preventable, just like many other things that have come my way in Portsmouth, but I won’t go into details as it serves no purpose. And yeah, you guessed it, not all freezes were caused by you, but I also know that you screwed big time with this particular Seagate.

    And for those non-believers out there… things that happened recently on this particular Seagate also happened on the newer computer’s now totally dead drive and on the other external HDD (i.e. messing with read/write permissions). Confirmation could not be clearer.

    And whoever is doing this seems to have hardware-hacking as his speciality…

    (And if you do not know what hardware-hacking is, that’s on you.)

    • Holy cow. The serial number printed on the box is not the same as the serial number that the drive gives me on the screen. Finding matching replacement parts could be interesting that way.

      • The HDD in my 32-bit computer remains a source of concern. While disks says it is “okay” now, R-Linux still flags it with “caution” because of its reallocated sectors count.
