Re: [PLUG] stick drive that mounts as /dev/sda (or sdb....)
|
I don't think you can have a drive without a partition table. Most thumb drives have 1 or 2 partitions on it by default. There are a lot of them that come with a separate partition with some proprietary junk you probably don't want. What does "fdisk -l" output?

Is there a reason why mounting a formatted usb stick drive with no partition table would be a bad practice?
During a meeting about two months ago, I mentioned I had a 4GB usb stick drive that I could only mount to /dev/sda (or b or c etc..). I eventually learned I could mount it to /dev/sda (instead of sda1, or sda2 etc..)
The drive mounts fine and I tried putting some large files in it, which also worked fine.
A comment was made at the meeting that the stick drive had no partition table, which was true. Though fdisk shows me a partition table, the data looks random, and a warning is printed that the device probably has no partition table.
Someone was also surprised I could successfully mount this drive to /dev/sda. I have googled and seen a few sites discussing doing the same thing.
All seems well. but is there a reason this is NOT a good practice (using the drive with no partition table)?
Here is some log information and a "df" command below:
