<i>&gt; &gt; IBM DPES 31800 will crash the partiotiontable if you use the mustel</i><br>
<i>&gt; &gt; driver on sga (iif the disk is sda)</i><br>
<i>&gt; The same goes for wrong access to a Yamaha CD-Writer as well... ;)</i><br>
??? How does this "work" ?<br>
<p>
<i>&gt; I made the mistake, that once I took an external CD-ROM out of the system,</i><br>
<i>&gt; and due to that all the SG devices behind it "moved forward" (sgc -&gt; sgb,</i><br>
<i>&gt; sgd -&gt; sgc). Unfortunately, that meant that the CD-Writer became sgb while</i><br>
<i>&gt; the second disk became sgc... Bye bye partitiontable..... :(</i><br>
Ah - yet I see - It was killed by CD-Writer-SW accessing the HD ...<br>
<p>
<i>&gt; I've done the same to the scanner (attached to a second box), and</i><br>
<i>&gt; I'd recommend this to everyone.</i><br>
I'd rather recommend that we fix the drivers to bail out safely, if the <br>
device attached is not what the driver expects. <br>
<p>
IIRC you can ask the SCSI-Inquiry data portably between devices, so you can <br>
check, if the device is right before sending any vendor-specific commands,<br>
right ?<br>
