Hey all, I have a TDS-754C that I've posted a few threads about as it appears to be a singularly problematic device. It has various problems, not communicating over GBIP when in unlocked mode being the primary issue, and I'm trying to dump the NVRAM EEPROM using the tdsNvramFloppyTool-extra tool in the tektool repo so I can avoid bricking the device while working on it, but unsurprisingly I've run into a bizarre issue. The scope seems to write to the floppy fine, and I can see the backup files on the floppy, but the backup process appears to have altered the floppy filesystem such that nothing can be read from it. I've attempted formatting the floppy both on a windows machine and in the scope itself, and the backup seems to create files on the floppy in both cases, but nothing can be read from the floppy once the backup has been created.
My only option for reading/writing the floppy is a USB floppy drive, which reads and writes everything fine _before_ the firmware backup, even if I've formatted the floppy with the oscilloscope, but afterwards it only shows the files on the drive, reading and writing throws a variety of errors depending on which operating system I'm trying to use.
Just as an example, I'm current using a Ubuntu system to try to read the floppy. I format the floppy in the scope, move it back to Ubuntu, copy dumpall.app and startup.bat on the floppy, then insert the floppy into the scope and power it up. A few seconds after powering up I get a message that the backup succeeded along with a beep. When I check the floppy in Ubuntu again, I see that the original dumpall.app and startup.bat have been renamed to d and s (this doesn't happy every time), I can see all of the files on the floppy, but trying to copy them results in "Error splicing file: Input/Output Error".
I'm honestly leaning towards getting rid of this scope since it's been so much trouble at this point, and appears to be causing problems that no other version of this scope does. But I figure if I can at least backup the memory I can start making more drastic changes.
