Hi, if I tape the hole of HD diskettes, can I use those without problems on MSX or is it strongly recommended to use 2DD disks only?

For swapping files taped HD disks are fine... For storing anything that is valuable for me I would take DD disks... and make backup anyway to some more modern media.

The dencity is different. If you've got pre-formatted HD disks, it's almost guaranteed they will NOT work as DD. Not ever formatted as HD may work some time.

They DO work. You can even format on MSX.

but as NYYRIKKI said, data saved by DD drives on HD disks tend to be unstable, so don't trust them to actually store files, just to transfer files.

No, they will not. https://www.msx.org/forum/msx-talk/hardware/trouble-floppies

Ok, with some luck they'll work some time, but it's very unreliable. I would say: just forget it and get real DD floppies from somewhere.

It is not that black and white... let's put it this way... HD disks work like summer tires work on icy road... I would not recommend driving trough the country with them, but if you only need milk from local store then most likely the trip goes fine... but not always... Naturally the drive it self and the quality of the individual disks have huge impact to experience. It is not that weird that some drive can't format HD disks at all while other drive may keep the data readable even for years.

After the mid nineties new DD disks became scarce.
As we never used recycled disks (except for a future disk which had their logo on the shutter... hmm... insider jokes Running Naked in a Field of Flowers ) we finally had to go for HD disks.
It must have been 1996 when this disk was released:

Still works like it was new.

This is just one example, there are more... But still I would not recomend HD over DD... It's more like a worst case solution.

If you really need DD disks, I can send them to you. I have many on stock. Most are used and there's also a large stock of new (but written to and labeled) PC-Active disks.
No guarantee that they work.

That's the problem with every disk right now.

Unfortunately, there are some tasks you most likely will still need a diskette to perform. And I'm not talking about copy-protected disk software: Flashing my Sharksym MMC/SD v2.2 is one of them (there aren't new firmware versions thou). I'm not sure, but I think this is the same case on other modern mass storage devices.
