ASR10 Woes

Just seeing if any one has ever encountered this issue. My Asr10 Rack will load the OS from floppy (in this case SD card) but not will not load or save samples. I have all other functions as far as sampling goes..however I cannot save. Each time I get a "Disk Error Lost Data" prompt. Originally I had installed an SD card reader because I thought it would solve the issue, but it has not.

I've replaced the ram checked the fuses and installed the SD card reader. No luck. Any Ideas??
