Hello,

To keep it precise;


  • - I have a Seagate 3TB External HDD bought around 5 years ago as far as I remember.

    - About half a year ago I had it encrypted via bitlocker and till two weeks ago there were no problems.

    - About three months ago I've set it to get unlocked automatically on my PC which runs on 8.1; once again no problems till two weeks ago.

    - The issue was that disk usage would remain at a constant 100% and explorer would keep trying to load it for hours to no avail. Similarly, anything that relies on explorer would hang too. As a result I haven't been able to reach the files inside the HDD.

    - I have managed to unlock the bitlocker encryption through cmd (manage-bde -unlock) and still got access to all the keys necessary in case if you'd be wondering. Yet having it unlocked does not change a thing as it still hangs.

    - Recovery software cannot access the drive either, despite all of them being able to see the drive with the letter.

    - The drive also appears as perfectly fine, working and functional on disk manager with a letter assigned, no unallocated space, no raw partitions, appearing as online. Displays a 'bitlocker encrypted' text over it if not unlocked through cmd. The said text disappears after unlocking bitlocker on the HDD through cmd.

    - I have also tried connecting the HDD inside through SATA after having disassembled it to give it a shot. Naturally so it is inaccessible through SATA as it is bitlocker encrypted, yet it made me wonder why it had an accessible ~350 GB partition (the 3TB is displayed as 2.7 on windows, so I am assuming it could be the remaining partition without encryption) on top of two seperate RAW partitions which seemed to be encrypted. Why two? I have no clue.

    - SATA2USB adapter seems to be functional as the PC has always recognised the HDD except for once when connected through it. HDD seems to be fine physically too, at least as far as I can tell, since it gets recognised, does not have any strange noise output, does not grind, click or anything.

    - The blue led on the stat2usb adapter inside the external hdd case sometimes just keeps blinking rather than remaining solid.

    - Tried everything I could also on my laptop, which runs on windows 10 and is fairly unused/clean. Unfortunately yields the same results.
To sum it all up: the disk usage is a constant 100%, it hangs, sometimes freezes explorer and if bearing too much load overall, also the computer or other processes, overall slowing down the PC.

Have no clue what to do at this point. Don't want to resort to bitlocker repair as I don't happen to have a spare HDD that I can use to have everything cloned to that is 2.5TB (that's how full the exHDD is).

Thanks in advance and ask away whatever info you might need from me; cheers!

Trying to but it's currently freezing both until unplugged, like a messed up CD would back in the days.

Will try to work around it and get you a screen hopefully.

Update: Well, can't replicate what I did before to enter disk manager without it freezing while the HDD is plugged. But when I could it said that the drive is intact and displayed the correct letter and allocated size.

At this point I'm not so sure that even bitlocker repair would work, as it would freeze to just like anything else.
 
Not sure, if it has that functionality then yes. This is one of the reasons that I won't use it, 1. nothing is that important that someone already in your house won't have access to more important things, 2. it makes really simple activities in emergencies much much harder.

I agree, bitlocker I'd pretty useless for me. Didn't actually need it after a while but never bothered turning it off. Well then, I'll need a new 3tb drive or borrow it from someone to make that happen.

Chances are though that it'll get stuck and bitlocker repair won't also work :/
