OK, after I issue the read-cmd and the ABRT occured, I directly fetch
the sector buffer and it contains:

7a424c0c0000100000e158023f001000

When I ignore the ERR-Status and read 512bytes anyhow, I'm reading
always this:

051760290510151037332e303455000d
0201251c120141123001530822015b1c

[...]

00000000000000000000000000000000


I've tried to read block 0, 1 and 2 - all reads are aborted, sector
buffer is always the same.
