    Windows Storage Space not Accessible after Hard Reboot

    I want to apologize of front if this gets a little long and winded but here is my story:

    Lately I have been having intermittent trouble with my video card. When playing one particular game I would have the driver crash. I have noticed the temperature of the video card running on the high side when stressed. This latest crash it locked up the PC so I had no option but to do a hard power cycle off and back on.

    When I powered it back up the system would hang in the BIOS at ‘press F2 or delete to enter setup’ right before windows would normally start. Pressing either of the keys didn’t have any affect. Several more attempts and the same result. I decided to strip out all but the absolute components necessary to run. I pull the video card and switched to the one on the mother board. I disconnect all of the USB devices except the keyboard/mouse dongle. And I pull all the hard drives except C drive with windows on it.

    Again, no dice, same thing. My next idea was to clear the CMOS. I jumped the CTLR pins, no luck same thing. I removing the battery didn’t help anything, removing the battery and jumping the pins, no luck. I tried every combination.

    Eventually I did get it to boot to BIOS where it gave a different message. I don’t exactly remember how but now it said something like press some key to recover bios settings. I thought great, we are making progress. Pressing that key did nothing, so I unplug the wireless keyboard/mouse dongle and plugged in a wired keyboard. This got back into BIOS setup, loaded the default settings and it booted to windows perfectly.

    I hooked all the storage drives back up and that is when the storage space wouldn’t load. This is what it showed:

    This is where I should mention that (4) of these drives are connected through a RAID card but not in any type of array and just exposing the disks individually. I pulled the RAID drives and got this to show:

    More messing around I got the drive that showed 'error' to just show a warning like the others. Keep in mind the drives that just showed the yellow triangle with the exclamation point were disconnected when I did the screen capture. Using crystal disk info all of the drives showed up and didn't have an warning in the s.m.a.r.t. data.

    Then I thought maybe I just got the the four drives on the RAID card out of order. So I tried every possible combination (there are only 24 total using 4 drives) Took about an hour but no change.

    Here is what disk management shows at the present time:

    At this point I have stopped trying different things. It could be totally fubar, and I have a full back on another storage space I keep offline, I hook it up once a month do a full mirror then power it down. I started this after I got hit with ransomware (thank god for windows shadow copy)

    It is just about 20tb of data and of course about three weeks of lost files. Anyone have any ideas how i can dive deeper into windows storage space and possibly get more info on what exactly the errors are?

    I appreciate you help,

    Given the complexity of your configuration and the impossibility of determining its resilience, and the potential multiple failures - if not of the drives, then the configuration- it seems impossible to suggest a clear way forward.

    Storage Spaces are not known to be friendly and robust when things go wrong- throw in part of it as a RAID configuration...

    Further, it has seemed few here use Storage Spaces.. so I rather doubt you will get the help you need, I'm afraid.

    I agree with Dalchina.
    I would say that you had a kind of array that was damaged with a change on the drive order on the 9650SE RAID controller.

    So you have a Raid card but don't use that Raid function, but instead uses Storage Spaces that is a bad raid solution.
    changing the disk order can break the raid array(depending of how smart your raid bios is). But as you do not use the hardware raid but only uses it as a extra disks. you might be lucky enough it don't matter.
    I don't know windows "Storage Spaces" solutions as it is not recommended to use it. But try to restore your computer with windows restore-points and see if you are lucky that windows is pulling the pool back together.

    I forgot to mention.. Login to the raid bios and check for disk messages/error messages..

    I appreciate everyone's comments and suggestions. I know the RAID controller probably wasn't the best idea but it gave me 4 more disk ports and allowed me to have a full backup of my storage. My motherboard has 6 SATA ports. At this point in time I probably have around 20 TB of data and it keeps growing. My storage backup is on (3) 10 TB disks also set up as a windows storage space and is fully functional. Once I rebuild the new storage space it will take a couple of days to copy all the data from my backup to the new array. And it pushes the drives hard while doing so, if one of my back up dives fails during the transfer then I am in real trouble. Over the years i have been replacing the smaller drives with new 10 TB ones. And I don't mind buying more.

    I would say by the end of the year i will be up to about 25+ TB of data. Given that what configuration would be my best option for resiliency and ease of recovery when I get another drive failure?

    As you have a hardware RAID card, configure as RAID 1 (Mirror). For each active drive you will need another (same size) for the mirror.

    You may also install a NAS drive and run a synchronization software every night.

    It is an old RAID card with only 4 ports and doesn't support 10 TB drives. I don't mind buying a new RAID card, it would need (6) ports and 10 TB drives to do RAID 1 and at some point in the near future i will outgrow it and be faced with a very large upgrade task. Also, it doesn't protect me from a ransomware attack which has happened to me in the past. So since I am faced with buying more stuff what would be my best option in your mind?

    No disk-setup protects against a ransomware attack if it slips by the antivirus protection software... all connected drives will be affected... and if it is design to spread over the network, every computer will be affected.
    The only way to protect yourself from ransomware is offline storage or to sett the drives in a write-protected mode so they are in read only.

    Raid/windows storage
    depending of you setting it up for performance or redundancy storage.
    Raid0 is better in performance but if one drive fails.. all data is lost in the pool
    Raid1 or mirroring is slower as you only get 1disk speed. but if one drive fails the data is still there and no downtime to restore the data thru backups and you lose 50% storage space and you have to have even number of disks
    Raid10 (1+0) is a combo.. you get better speed but has mirroring you lose 50% of storage space as with raid1 and as raid1 even number of drives.
    Raid5 you get more speed and you can lose 1drive in the pool without data loss or downtime so if you have 3,4,5,6,7drives you only lose 1drive of space
    Raid6 same as 5 but you can lose 2drives in the pool at the same time. so if you have 4,5,6,7 drives you will lose 2drives of storage space.
    it is really rare that two drives fails at the same time. I have never experienced that. (then in the 90's when an lightning strike and killed 20drives in one millisecond.)

    as for windows storage space.. i have no clue if it even has a redundancy setup as raid 1,10,5,6 has. (i would not use it even if microsoft payed me)

    when you using raid (software raid or hardware raid) CMR drives is preferred then SMR as they are a bit faster (never mix CMR+SMR in the same pool)... and also best and most common practice is to have the same size on the drives in a pool even if some setups do allows it.
