I have been an MX-2424 owner since 2000 and it was my main production machine for many years but have not used the machine in a long time. I am looking to export and archive some old projects and in an attempt to update to the latest OS it appears I have corrupted both the flash memory on the machine and on two Tascam-supplied SmartMedia cards. I am hoping to format the SmartMedia cards and copy the latest (3.12 I believe) MX-2424 OS to them, and then install on my machine. I am running Windows 2000 on an old Dell, with both MX-View and Viewnet installed as well as Mac OS 10.13.6 on my mid-2010 MacBook Pro. I have a Lexar card reader that both computers are recognizing but the SmartMedia cards are not showing up on either. Your help would be very much appreciated. I'd love to get the machine working again and utilize the batch download feature in the latest MX OS so I may transfer files via ethernet. Thanks!
