and

fdisk -l

returns nothing except for the command 'fdisk -l' being echoed back to the screen.

Even though I can boot with CWM; when booting CWM, it displays the following error messages

E: Can't mount /cache/recovery/command
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log

When trying to install "NookColor-emmc-repair-partitions-1-4-5-6-7-8.zip", I get:

-- Installing: /sdcard/NookColor-emmc-repair-partitions-1-4-5-6-7-8.zip

Done. YOU MUST REBOOT TO RELOAD THE PARTITION TABLE

Install from sdcard complete.

Then, rebooting and installing "NookColor-emmc-format-partitions-5-6-7-8.zip" generates the following output instantly, with absolutely no delay when the formatting should be occuring:

-- Installing: /sdcard/NookColor-emmc-format-partitions-5-6-7-8.zip

Trying "NookColor-emmc-repair-partition-2.zip", ends with:

-- Installing: /sdcard/NookColor-emmc-repair-partition-2.zip
E:Can't mount /cache/recovery/last_install
E:failed to open last_install: No such file or directory

and then after not making progress with those; trying "NookColor-emmc-stockrecovery-CWM6012asAlt.zip" returns:

-- Installing: /sdcard/NookColor-emmc-stockrecovery-CWM6012asAlt.zip
