HW hack - change old slow HDD to a CF card?

[trodas]

Segate 13G ST313021A on Pentium 90 @ 125MHz:

Average - 6.4MB/sec - now this is SPEEED!

...

I wonder, if anyone have in operation slower HDD

...

Therefore I wonder, if someone have a experience with replacing such SLOOOW HDDs with PATA to CF adapter and CF card(s)? The latest models promise very fast speeds - 160MB/sec is quite above PATA possibilities:

...and since the adapters are just wires, connecting the CF card to PATA interface (CF cards work on same PATA interface!) and only in best cases, you can choose the voltage (3.3V or 5V) and you get the power and activity lights:

...then there should not be any problem of using CF cards as old PATA HDD replacement(s). Only problem I hear, that there should be changed bit on the card somewhere, that change the device type from removable to fixed. Then it should act as normal HardDriveDevice.

But maybe I missed something...? Do anyone have experience with this? Could someone share tips, software for the change (from removable to fixed) and experience in general?
