<i>&gt; &gt; i'm using sane 1.0.1 and have tried both the src-0.8 and src-1.0 patches </i><br>

<i>&gt; </i><br>
<i>&gt; Right now I don't have any suggestions for other things to try. I guess</i><br>
<i>&gt; you could try sending me a sample image or two to look at (though if</i><br>
<i>&gt; it's the same problem as I've seen before, that might not do much good).</i><br>
<i>&gt; </i><br>
<i>&gt; Try seeing if images less than 64kb long scan OK. It's probably best to</i><br>
<i>&gt; use greyscale for this. I assume that the problem is the same</i><br>
<i>&gt; regardless of the scanning mode, right? With what I've been told before,</i><br>
<i>&gt; the first 64kb or so of image data is OK, and then after that it becomes</i><br>
<i>&gt; garbled.</i><br>
<i>&gt; </i><br>
<p>
ok, finally have gotten my scanner to cooperate with my scsi hard drive so<br>
i can go back to getting this thing to work. i have checked what you just<br>
said and i am able to get greyscale images less than 64k to scan in ok. i<br>
tried a color image at 59.9k and the top half of it was fine, but then it<br>
got worse towards the bottom. if you'd like to see i can send you some of<br>
these. i should probably note that i'm basically going blind because the<br>
preview in xscanimage/xsane isnt showing me much. i can choose pretty much<br>
any section which is &lt;64k an it will get at least part of it scanned in<br>
ok. very small scans (~15-20k) seem to come out great.<br>
<p>
<i>&gt; A fellow mailed me a couple of days ago saying his SnapScan 600 would</i><br>
<i>&gt; scan in colour mode really slowly (about half an hour for a full-size</i><br>
<i>&gt; image). He found that there were two sg.h files on his system, that they</i><br>
<i>&gt; were different, and that the scsi driver and sane seemed to be using</i><br>
<i>&gt; different ones. You might want to run</i><br>
<i>&gt; </i><br>
<i>&gt; find /usr/include -name "sg.h" -exec ls -l {} \;</i><br>
<i>&gt; </i><br>
<i>&gt; on your system and see what it turns up. Maybe something similar is</i><br>
<i>&gt; going on here. It's a long shot, but worth trying. </i><br>
<i>&gt; </i><br>
<p>
checked that and it doesnt find anything. i also did a<br>
<p>
diff /usr/src/linux/include/scsi/sg.h /usr/include/scsi/sg.h<br>
<p>
which i saw someone else mention and there was no difference.<br>
<p>
<i>&gt; BTW what versions of the kernel and SANE are you using? (Sorry if I asked</i><br>
<i>&gt; this before)</i><br>
<i>&gt; </i><br>
<p>
kernel 2.2.13 and sane-1.0.1.<br>

if you have any other suggestions, just let me know. i should be able to<br>
pick at this now. let me konw if you'd like to see some samples of what<br>
i'm getting in as well as what the previews are looking like. thanks,<br>
