    Lost Drives after upgrade


    I upgraded from win 7 64 bit to Windows 10 "c drive" and lost my two drives (E and F) that I use as backups to my primary drive.

    My primary "c" drive is actually 2 drives that are mirrored so if one would fail I can replace it and not lose a thing. These are 1TB drives so total space is 1TB

    I have two additional drives (E and F) that are 3TB in size and while I use Robocopy to keep these drives in sync, They are technically an additional 6TB of space I can use. Anything of value from C drive is Robo'd over to E for backup. Then I Robo the Entire E over to F so I have two backups on C and one backup of E.

    After my upgrade E and F are gone. I will lose Data if I can't get E or F back.

    You will notice that my C no longer looks to be mirrored and from File explorer I would agree it no longer is.

    How do I get my E and F back. They are disk 2 and disk 3 and if I right click on them all options are Gray except help if I Right click on the 2gb space or offline, properties, help if I Right click on disk 2.

    :)

    Windows 10 incorrect start up PXE over IPv4 and start PXE over IPv6

    Not connected to a LAN.

    Previous Windows version 8.1.

    The upgrade to Windows 10 was made a long time ago. Read online about someone who lost there D drive after upgrading to Windows 10. I don't use the D drive often, so not sure if I lost it when I upgraded to Windows 10. Don't remember for sure how I upgraded
    to Windows 10. Thought I went to Microsoft's site.

    Another user had a similar problem as yours, he ran chkdsk on the drives affected, and it fixed his problems.

    That did not fix anything.

    You can use Easeus partition master free to first recover the data on disk 2 and 3, then repartition the two disks and save the data on them again.

    From the screen shot, the 2 partitions are GPT Protective partition
    This type of partition protects GPT disks from previously released MBR disk tools such as Microsoft MS-DOS FDISK or Microsoft Windows NT Disk Administrator. These tools are not aware of GPT and do not know how to properly access a GPT disk. Legacy software that does not know about GPT interprets as GPT Protective partition when it accesses a GPT disk. With this type of partition, you cannot format, assign letter.

    OPTION 1: use a free third party partition manager such as: AOMEI Partition Assistant Standard to convert these 2 disks into MBR disk type without data loss since Windows Disk Management tool does not have this feature.

    OPTION 2: Connect these 2 disks to the previous versions of Windows such as XP, Vista, 7 then you'll see them again which you can backup your data to another disk then re-initialize them to be a GPT type disk since the 2 disks you have both 3TB. With GPT disk, the partition can be greater 2TB while MBR type disk is limited to 2TB.

    Hope this helps !!!

    Thanks Topgundcp,

    My concern is why they are now a GPT protected drive. Before the upgrade They were already a single 3TB partition. Because of that I think I will go the route of putting them into another windows 7 box. I would be concerned that I will have some data loss if I convert to mbr since I would expect there must be some files that would fall in the slice between the 2TB and 1TB partition.

    Am I off base here?

    Yes, to be safe, just connect them to a Windows 7 box then try to save data to another MBR drive and test with Windows 10. Once done, re-initialize the 3TB to GPT type disk, format and copy back your data.

    Here is what it looks like in a win 7 box. If I initialize it, will scrub the data on it?

    and a second question is what is a good boot utility that I could use to just look at the disk to see if the files are still on the drive?

    Try this app, made by one of our members, just put these files on a usb stick. Then boot it up.
