Hi,
I had a look at DLA on wiki http://en.wikipedia.org/wiki/Drive_Letter_Access . In the references I followed the instructions of Argentuma http://www.argentuma.com/backup/software/dla.html . However, the IBM DLA did not install itself, the Dell DLA v5.00 was simply nowhere to find and the Dell DLA v4.98 made my Sony Vaio crash very badly. So, if it comes to DLA drivers for my computer, it is zip, nada, nothing until now.
For your info, the Vaio drive is a SONY DVD RW DW-U54A (firmware v1.5a) drive.
Have you any knowledge of DLA soft which is reliable in your opinion?
Johan
