All the following was done in the live system: sudo fdisk -l returns only /dev/sda1 blkid returns /dev/sda1 (whose label and UUID confirm that it is the USB drive) and /dev/loop0. I found the mountpoint of /dev/loop0 using mount, but it appears to be completely empty. Well, the usual directories, /bin, /boot, /home and so on, are there, but they are empty. I ran cat /proc/partitions, and it returned entries for loop0, sda and sda1. I attempted to mount /dev/sda, and got the error that it was already mounted or the mount point was busy. The output of mount only lists sda1 being mounted. But I guess sda is a partition on a device, not an actual device. I ran lsblk , and it returned the same devices, sda, sda1 and loop0. I was confused by the message that all the devices I could find are already mounted, so I thought maybe the local hd is already mounted somewhere. I tried a brute force approach, looking in all the directories listed in the output of mount, and couldn't find the files on the hd. I then realized it would be faster to run: find -name name_of_my_local_regular_user_home_directory This returned nothing, so that confirms the local hd is not mounted. But I already suspected this. The UUID shouldn't change, should it? Isn't there some way I can mount the device by UUID using the mount command? All the web pages I could find are about setting up /etc/fstab to automatically mount by UUID. I don't believe any changes to /etc/fstab will persist after reboot on the live usb. My reading of the mount man page led me to believe that sudo mount -U uuidnumber mountpoint should work, but it returns 'no such partition found' Thanks, J -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.22 (Darwin) Comment: GPGTools - https://gpgtools.org iQEcBAEBCgAGBQJUNBTyAAoJED6rE5ImPwfDcdsIAKKFVLQETNQX4bDLpMLklRQ8 ih9ySXMDDALWq9DqG1i7F1H5ASq9c03hNWLWlIMwH+pcBiuHsB44UOBbPYw9ITiV ajhDIg2q1g1ho/UY/kwCQ0Xfnglsq65CRbEQSwE2HxH0GUtc4+aEMPVqWYmrFFro Od2dwKub22tFXbvC2kosUMz4IQR4ma9CLMDeUCVry2TQ7fTSTn4c1m99NBbZzt0p 1ClyXmCuau94olvUFExZB2M2fpPk66itkTC1aLDyMtXiVHTXk9VBM3kEE3EP1tFU U8knKiiTaAIbSQ55jQrN6hL5n5i27ppv9DeTHc+E/ac30Lc0zlOMcKeHTFYHj9E= =Yoz6 -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
