So last night I hooked up a GPIB adapter and cleared the error log on my TDS 784C. While I was in there I enabled option 2C just for the heck of it, re-enabled the write protect and rebooted, congratulated myself that 2C was now showing in the list of options but something seemed a bit off about the list. Went back and checked an older screenshot that I had and sure enough, HD was missing from the list. Checking the file utilities confirmed that the hard drive is not listed anymore. What the heck? I just used the hard drive a few days earlier, I honestly don't know if it was listed when I powered up and connected the GPIB interface, I wasn't paying attention to that. Is it possible that I somehow disabled the hard drive?
Thinking the drive failed, I removed the PCMCIA drive and popped it in an old laptop, the drive enumerates in Device Manager but doesn't show up anywhere as a disk. So I tried a CF card in a PCMCIA to CF adapter and that mounts as a drive in the laptop but put it in the scope, power it up and still no option HD. Opened the lid on the scope and had a look around, everything looks fine, all the cables connected, power it up and I can hear the drive spinning. Not sure what to try next, anyone know if the drive is a standard FAT format? Should a CF card in an adapter work? Is there any diagnostic function for the hard drive built into the scope? I've looked around and it seems there's almost zero information about this feature.
