mfsadd - Can you undo this?

Sticking at 'powering up' suggests that the B drive is interfering with the A drive. This could be due to a jumper problem.

There's no way to undo mfsadd. All you can do is restore a backup to the drive. Your recordings are not likely to survive this under most circumstances.

 

I had the EXACT same problem a few weeks ago with my first upgrade.

I made a back-up of the stock 40 gig drive, performed "mfsadd" with a 120g Maxtor as "b" drive (PC indicated upgrade was sucessful), and no matter what the jumper config, it would get to "A few more seconds" screen, and reboot.

I sucessfully restored my backup image to the stock drive (38 hours of recordings still on stock drive), and removed the "-s 127" from the restore command, and performed "mfsadd" a second time.

Instant success! I don't think I did ANYTHING different, but "mfsadd" worked the second time no problems - 144 Hours. Weird. My recordings are still entact on the old drive, and all is well on the new drive.

I see that you got everything working after you did a second mfs add, but did your original drive just work by itself after doing the restore withtout the -s 127 option? I ask because I originally did an mfsadd and couldn't get both drives to work together, then ended up just restoring my backup to a larger drive and putting it in my tivo and it worked fine. However, what I want to know is, after having done that mfsadd, can I restore my backup to my original drive without the -s 127 option and have it preserve recordings but still function in another tivo by itself?

The only way your recordings will survive is if the partitions created by mfsrestore line up exactly with the partitions already on the disk.

Obviously, changing the size of any of the partitions will move the other partitions.

 

I tried to add a 40gig B drive to my existing stock 60gig, I was getting the same errors at startup that was discussed in this thread. I now have a 120gig that I want to use with the 60, how do I go about getting it to work. I have tivo 14***.

 

hey i just read ur post about after doing an upgrade getting stuck at the few more minutes screen, well i was a dumb butt and didnt back up my original drive, do i need a new image/os of tivo, what do i do?

 

If the A drive is fine, you can backup from that.
