I've got a 2TB Toshiba drive (formatted as NTFS) that has become very slow and I was wondering if anyone here as any ideas what the problem could be and how I could fix it. All the data I'd need off the drive is backed up, but I would at least like a drive to put it back on to!

In short, it became slow after I had to force power-off the system it was connected to (Pop OS installed on another external drive which I unplugged by mistake) and I haven't bothered to try to fix it in the six months since.

I've tested it on Pop and it takes about 10-20 minutes to mount, and 2 minutes to unmount and safely remove. The data itself seems fine but performance is slow, accessing a 20MB image takes several seconds and selecting the drive in GNOME Disks caused it to freeze.

The drive sounded louder than normal, especially after plugging in.

On Windows, the drive was recognised and browsable immediately, but browsing through folders was very slow - opening some folders causes Windows Explorer to freeze for a while. Some of my double-clicks were mis-recognised as click-to-rename, which took several seconds to activate and during which time Task Manager reported the average response time between 5000 and 11000 ms.

Attempting to load an audio file resulted in lots of buffering. Task Manager reports an active time of 100% (even when not loading files or folders) and the activity never exceeded 100 KB/s (and doesn't sustain it for more than a second). Ejecting the drive takes forever - after ejecting it using the tray icon, the tray icon is not removed (even though there are no other drives connected or listed) and the active time is still 100% with the indicator LED blinking non-stop. The system did not enter sleep right away after me asking it to either.

All of that to say, does anyone know what the issue could be, or how I could find and fix it? Thanks!

Edit: fixed and normal functionality restored (at least so I can check the drive a bit easier) using Scan & Repair in Windows (see my comment).

Here is my understanding of Bitcoins, would love to hear from people more knowledgeable than me on what I am getting wrong

• Only a certain number of bitcoins can be mined
• if the price of bitcoin goes up, it makes mining seem more profitable which encourages more mining
• If there is more mining, the difficultly of mining eventually increases, & so miners consume more electricity until mining becomes less profitable again
• Bitcoin is already consuming so much energy that countries are starting to actively discourage mining

This implies that any substantial increase in bitcoin price will result in substantial regulation of the bitcoin industry as it impacts the supply and price of electricity to other industries

• Bitcoin is highly volatile, and over time has increased in price substantially
• A significant portion of bitcoin investors are speculating on an asset rise
• If the asset stops rising, some speculators may start to sell
• Increased selling activity will lower the price
• A lower price will force more speculators to sell

This implies that if bitcoin does not keep rising, it will start to fall

• Other crypto currencies are highly correlated with Bitcoin price movement.

Therefore if bitcoin falls, other crypto currencies fall.

• Bitcoin is the current default for accepting cryptocurrency as payment
• Bitcoin has a limited number of transactions it can process (3-7 a second)
• If too many people want to process transactions, the fee will rise

Therefore one or more other cryptocurrencies that uses proof of stake, must become the default for accepting cryptocurrency as payment.
