I have seen these lines (in fact, a swapped bit within
a RLL encoded bitmap, for example TIF compressed) on
two occasions:
1) years ago, an editress *copied* pictures from her peecee to
an Novell 3.x server (Win 95, Token Ring adaptor, IPX/SPX transport).
Almost every picture (even small screenshots) was corrupted, her computer
has been the only one exhibiting the problem at an ~500 nodes network.
Because her computer was running stable, assumingly the adaptor
was faulty. The has never been done much investigation onto the problem
because the company moved to a new location two or three month later
and almost the whole computing equipment got replaced.
2) ASIP 6.2 server running on G3 b&w, 100 MBit network,
256MBytes of faulty RAM:
That server has been running just slightly unstable -- a crash every
three or four days. Copying files to the server or from the server has
never been a problem -- *BUT on opening* files from the server with
Photoshop almost every file larger than one or two MBytes got corrupted.
Opening the same file several times in a row, corruption was visible
at different locations in the picture. btw, *saving* a file from PS
right to the server has never been a problem as well.
After month of troubleshooting server software, network cabling etc.
the RAM got replaced and no file corruption anymore. Turned out
the RAM apparently wasn't completely up to specs (both modules --
not "no name", but cheap brand -- had to be replaced).
hope this report gives you an idea where to investigate (hardware!),

Please tell me more about these lines appearing as a result of disk error.
