Re: Re-mount a drive using its label name

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



@Mauricio: Yes the drive's sd name keeps changing with removal and
addition. Thought labels can be used as alternative to maintain
consistency. As you can see in my dmesg output, sdf changed to sdj

@zep: No I do not use partitions. I use the entire drive.

@mark: This is my dmesg output,
