Having issues with WD My Passport External HDD

I have a WD My Passport 1TB External HDD that is (or was last I accessed it) set up as one big partition for the whole disk formatted as NTFS.

Windows recognizes the drive when I plug it in but if I try to access it (via explorer or command prompt) it says "G:\ is not accessible, the parameter is not correct". If I look at the drive in the windows disk management tool, it claims its a "raw partition" and keeps saying "you need to format this partition before you can use it". Running chkdsk on that partition it correctly detects it as NTFS and has spat out "Error detected in index $I30 for file 27." as the only error so far (its only on "stage 2 of 3" though)

Eassos PartitionGuru can see the disk and its files and can copy files off without an issue (but that doesn't help me as I have nowhere to actually copy the contents of the disk to unless I go and buy another 1TB external drive)

When I ran "WD Drive Utilities" earlier it passed the "Drive Health" check or whatever it was but the other checks of the drive itself failed.

Anyone know what might be going on with my drive? Is there a way I can recover the drive to normal working order? Would re-running chkdsk and telling it to fix whatever errors it found help? Should I copy the data off somehow and reformat the drive? (e.g. using PartitionGuru since that seems to work) Should I be worried the hardware is failing (or has failed) and stop using the drive completly?

Biggest problem I have is that I dont have enough disk space on other drives to copy whats currently on this one onto and no money to buy a new disk for such a purpose (even assuming the drive is stable enough to read data from which it might not be)

That said, the failing drive isn't mission critical (it was purchased just over 2 years ago as a way to back up the then-contents of my other storage disks before I moved house and had to trust that the airport baggage handlers wouldn't damage my stuff when moving my computer to the other side of the country and from memory I dont actually have anything on there that I couldn't live without so maybe I should just ditch the drive and move on)

If it was as simple as copying the data off to somewhere else I would have done it by now...
But I dont know that the drive is stable enough to read all the data off of, nor do I have anywhere I can put said data (unless I spend money I cant afford to spend buying another 1TB external)

How likely is it that the drive will get worse if I leave it disconnected sitting in a drawer? (until I decide whether its worth trying to recover stuff from it/can afford to buy a new drive to put the contents of the old one onto)
