I believe this is a common problem with these PCBs, ie not a misadventure by the user.CrazyTeeka wrote: ↑Thu Nov 16, 2023 7:44 pm Hmm. New batch of drives arrived from eBay seller. One of them, a Quantum Fireball (IDE) has a burnt chip. Wonder how that happened?
It just shows how much of a bubble these gusys are in. I don't think there is a data recovery or storage related forum on the English speaking internet where Franc isn't an active member, usually correcting the pros with his seemingly unlimited knowledge.
Yes, this is more or less what I expected. Thanks for asking him!lcoughey wrote: ↑Thu Nov 16, 2023 6:30 pm Here is a response from Serge:Serge@DeepSpar wrote:We’ve noticed cases like this several years ago, i.e. drives which would read 1 of 8 logical sectors from a single physical sector. We thought it might be a bug with our tools, so we spent some time testing this, concluded that this is real drive behavior sometimes, and dropped the subject. It’s a bit hard to remember at this point, but I seem to recall that this 1 logical sector that comes back as successful isn’t actually a real read, i.e. it’s garbage data that’s coming back due to some firmware bug of the drive. You guys can check this out, i.e. read that suspicious good sector and check if hex values seem valid.
A key point of larger sector sizes is to combine the ECC together because less space can be spent on ECC that way, so it’s extremely unlikely that any drive is able to successfully correct only 1 logical sector from a physical sector, it should be all or nothing. IIRC drive firmware doesn’t even have a concept of logical sectors internally, there is just a conversion that takes place at the end.
LOL!but your facts are wrong because you are assuming that you know and understand what SpinRite is doing.
You got friends?CrazyTeeka wrote: ↑Thu Nov 16, 2023 9:35 pm I'll have more time after the weekend. Going to see friends over the weekend.
