Weird Hardisk problem...

[Fnac]

Hello,
I have a problem with my Amiga 1200.
Sometimes when trying to save files to HD, the workbench takes a long time, as if you were saving a large file, and the system is very slow. After a while, the system reboots and does not boot from the HD.
I have to do a hard reset. When I analyze the file on the disk it has the size of -4.
I have already formatted and installed the operating system.
I changed the hd to compact flash adapter to a SD card.
And the problem remains.
Does anyone have any idea what it might be the problem?

My system:
Amiga 1200
ACA 1232

Thanks

@Pat the Cat
Thanks for you suggestions.

I have some questions:
I have 3.1.4 roms installed and the i'm using the FFS v.46.20 that came with 3.1.4. Should i replace with the PS3AIO instead?
The max transfer rate of the drive is already set to 0X1FE00.

I read that ACA1232 with amiga 1200 could have timming issues (http://wiki.icomp.de/wiki/ACA1232).
Can be this also the source of the problem ?

Thanks
