On an Acer Aspire One 522 netbook, the boot process stalls with the message: "The disk drive for /media/SDbackup is not ready yet or not present. Continue to wait, press S to skip or M for manual recovery."
If I eject the relevant SDcard and re-insert it (essentially using the wait option), boot-up continues normally, and the card is mounted.
If I press Esc, the message displayed is:
fsck from util-linux 2.20.1 Ubuntu: clean, 382442/1343488 files, 1480572/5349632 blocks
If I press M, the message displayed is: Filesystem check or mount failed
Interestingly, on a Dell Inspiron laptop, a similar SDcard is mounted automatically on boot-up without the above-noted message appearing.
To provide some background on the netbook system, listings from the fdisk command and the contents of the fstab file are appended below.
Note that using "/dev/sdb1 /media/SDbackup/..." or "UUID=AAC4-9403 /media/SDbackup/..." in fstab produces the same boot-time message; however, the latter entry also produces double listings for SDbackup in the (Gnome Classic) "Places" menu. Consequently, it is currently commented out in fstab.
I have run fsck on the card. This did not identify any errors. I have also re-formatted the card. I used a different SDcard in the card reader. Nothing seems to make a difference to the boot process stalling.
There seem to be multiple bug reports about similar issues with this boot-time warning message but I am unable (in what appears to me to be a complex logging system) to determine if there has been any fix.
Can anyone suggest another approach to mount the Sdcard automatically on boot-up? The intention is to have this available for "real-time" backup of a data partition using inosync.
