    2TB drive showing as 8TB


    I got a drive enclosure from an old server loaded with 2tb drives, there's 5 total and I'm 100% sure the slot the drive is in works. When moving drives between slots checking if the slot was dead all other drives registered as 2TB and worked however this one drive displays as an 8TB and also doesn't want to be formatted or erased via computer management>disk management.I've tried converting to GPT via cmd prompt found something else online however its already GPTsubsequently tried converting to MBR and that also didn't workshows as a regular disk in diskpart but not in computer manageme

    :)

  2. If I have a 2TB D: secondary drive in in Win 11, can I replace it with a 4TB, or larger?

    Currently I have a 2TB C: drive, and a 2TB D: secondary drive, both SSD devices.

    Can anyone tell me how much larger a drive I can add as a D: drive?

    4TB, 6TB, 8TB?

    I'd be happy with 4TB, but can it be done?

    Thanks in advance.

    Cloning from 1TB to 2TB hard drive

    Whats a good free imaging/cloning program? I have a 1TB hard drive with Win7 and I want to seamlessly migrate my stuff to a 2TB hard drive. Any suggestions?

    Windows Disk Management incorrectly detects USB 3 drives over 2TB

    Problem: Windows 10 Disk Management does not correctly detect drives over 2TB connected via USB 3.0 to SATA adapter.
    Instead of the correct size, it shows 16380GB (aka 16TB) no matter what drive I connect. No drive letter can be assigned and all partition options are gray.

    I am using the following setup:

    • Windows 10 x64 Home on an Acer Predator notebook
    • LogiLink Adapter USB 3.0 to SATA (AU0013)
    • Larger than 2TB drives, formatted previously GPT on Windows 7
    • All drivers up to date, all drivers re-scanned for force-update

    Other details:

    • I have 2 adapters that I tested and they behave the same (simultaneously too).
    • I have tested with 3TB Seagate older HDD and 8TB WD Pro HDD. Same size is incorrectly shown: 16384GB.
    • I have tested smaller than 2TB drives and they are detected correctly.
    • I have checked diskpart and it shows the correct size for each drive.
    • Disk Management lists the partitions as "GPT protective partition"
    • I assume the problem is with the bridge translation, but how do I fix it ?
