UAE USB Amiga Hard Drive

[Thomas]

Try to run WinUAE with the -disableharddrivesafetycheck command line option.

Try to check the drive with RDB-Salv or RDBRecov to see where the data is and why it is not seen. Perhaps the USB controller somehow differently translates the drive geometry or uses part of the drive for itself, leaving a different amount of blocks for the OS.

Just tried both programs & they both fail to open the device giving me the error "unable to open uaehf.device"

Then you did something wrong. If HDToolbox can see the drive, those tools can either. Make sure you use the right unit number.

And I am quite sure that at least RDBRecov does not say "unable to open uaehf.device" but "unable to open uaehf.device unit n". I know that because I wrote it :-)

Must be something to do with the USB controller although Ive never had any problems with it in the past using Windows drives.

Did you connect those Windows drives in your Amiga and tried to mount the DOS partitions ? Are you sure that sharing a drive between the Amiga IDE controller and an USB IDE controller should work ? Perhaps there is nothing wrong with the USB controller. Perhaps (probably) it is just a matter of "works as designed".

I still cannot believe that HDToolbox sees the drive and RDBRecov doesn't. Could you make a screenshot of HDToolbox showing the drive and of the CLI window after you ran RDBRecov.

What does HDToolbox see when the drive is connected to the A1200 ?

Please run RDBRecov again with the values used by HDToolbox when run on the Amiga.

How many partitions are on the drive ? Which file system is used ?

I would like to see a dump of the first few blocks of the drive. Could you run the following program once on WinUAE and once on the Amiga for comparison:

http://thomas-rapp.homepage.t-online.de/download/blockdump.lha

use it like

blockdump uaehf.device 2 0 16 >ram:dump

where 2 is the unit number of the drive as it is used by RDBRecov, too. 0 is the first block to read and 16 is the number of blocks to be read.

If the dumps are totally different, could you please try to find the blocks dumped by WinUAE on the drive when connected to the Amiga. I guess they come somewhat later on the drive and that's the reason why WinUAE cannot find the RDSK block. It's just cut off by the USB controller.
