Windows 10: BSOD ATTEMPTED_ SWITCH_FROM_DPC while using AOMEI Backupper

    FYI, I couldn't get AOMEI Backup to work under Gandalf's Win10PE. Complained about a bad driver. I will try AOMEI's WinPE, perhaps tonight. Meanwhile, I used FastCopy to selectively get all the important things I could think of off the drive. (It's the first time I used FastCopy & it lived up to its name! Also didn't choke on long paths.) Dell is supposed to come tomorrow to replace my hard drive.

    Looking at the benchmark result it indicates that the HDD is failing.
    I am curious as to what aspect of the Benchmark test led you to conclude the disk is failing? The absolute numbers? The performance pattern in the graph? Something else?

    Thanks for all the help.

    Look at the amount of the transfer rate minimum and the pattern, it is 0.3MB/s and an average of 2.2MB/s. This means that the hard drive reads data at a minimum of 0.3MB/s, at best 57.2MB/s and normally 2.2MB/s. This is slow.

    The lower the transfer rate is getting, the slower the HDD is going to perform. Ultimately it will take a long time for data to be read and the mechanics of the HDD is physically failing what could result in an unbootable HDD.

    This is just for comparison.
    From what I read, your HDD has a 7.200 RPM. I have a laptop with a HDD of 5.400 RPM. The HDD reaches a maximum of 120MB/s and a minimum of roughly 50MB/s after a few years of use, which is reasonable.

    I see. So basically, it's the incredibly slow performance that is the telltale sign. That explains a lot of things. My machine's been getting progressively less responsive in the last year, especially for things related to the file system (e.g., opening a common dialog). I had thought it was just the OS getting choked with all the detritus that I accumulate over time - I was planning to do a wipe-reinstall because of that, which is why I decided to do a full system backup (aside from my regular incremental CrashPlan backups). Odd this degradation - my disk is only 3 years old. I have other disks on other machines that have been running for a decade or more.... But this machine is my main workhorse now. I'll report back in a week or so after my disk is replaced and I've loaded it up & broken it in. I'll try Backupper again & see what happens.

    BTW, FastCopy managed to do most of the copying at the top of the Benchmark speed. I was impressed by it. (I'm looking forward to being more impressed when I'm back to normal high-speed performance, though!)

    Thanks again for all the help.

    Odd this degradation - my disk is only 3 years old
    Degradation happens for various of reasons, like
    - amount of usage, expected
    - amount of crashes (BSOD, powerloss), unexpected.
    Generally speaking, HDDs usually lasts only a couple of years (3-4), with some luck twice that time.

    An example of the mentioned unexpected reason, something that happened to me.
    A large amount of BSODs could cause the HDD to degradate, not because of the BSOD itself but the cause what triggered the BSOD, the BSOD is there to protect the system and your data.
    When I had my laptop the first couple of months, 4 years ago, I had a ton of BSODs. Everytime a BSOD occured I couldn't boot, everytime this was resolved by starting all over again. However, after some time I couldn't clean install anymore, I ran the Dell diagnostics that I accessed through the boot menu. The diagnostics revealed that the HDD died. I presume that the HDD died because of the amount of BSODs I had, in other words the forced powerlosses and possibly bad data written to the disk, another factor was that I was terrible at maintenance at the time but a novice like me wouldn't have thought about that at all.
