I have just recently moved, I had a HR-22 hooked up to my external hard drive, well when I had the new install done, the HR-22 would not boot up, so my direct tv tech replaced my old HD DVR with a new HR-24-100. (which I rewarded him for, for helping me out) Anyway, when I had this done, I also had the whole home dvr activated. After this was completed, I reformatted my 1tb external hard drive, which was done by my I.T. department at my work site. I took my hard drive home, unplugged the power cord to the HR-24, hooked up the esata cable to the back, then turned on the external hard drive, then plugged in the HR-24. Well, when it powered back up, i went to my playlist, and it didn't reconize the external drive. I repeated this process 2 other times, and tried with a different hard drive, i'm using a western digital 1tb, also tried a seagate 1tb, to no avail. Any help on this matter would be greatly appreciated.
