The main page of this article lacks a description of volumes used in non-FAT file systems.
The article could be improved if there were a few paragraphs on the usage of volumes in non-FAT file systems. Dexter Nextnumber (talk) 01:39, 11 January 2010 (UTC)
According to sections 5.6, 5.7 of part 3 of ECMA-167 (which is the framework for the UDF standard used in removable media such as DVDs,Blue-ray discs, etc.)
A Logical Volume is defined as: A logical volume is a non-empty set of partitions.
A Partition is : An extent of logical sectors within a volume. (An extent means a set of contiguous sectors)
The above definition for logical volume seems quite different from the one mentioned in this article.Of course, the definition might be only within the scope of the ECMA-167 and UDF documents, but these are major standards, and may still be a cause for confusion. (It certainly caused me confusion,because my idea of what a Volume is, was based on this Wikipedia article)
Any expert on the subject can clarify this? —Preceding unsigned comment added by 94.59.101.245 (talk) 14:16, 2 July 2010 (UTC)
On an IBM Series/1, under the EDX operating system, the name "volume" referred to a concept which was quite similar to a partition in that it was of fixed size and could not have any sub-volumes (except on floppy disks), and was used as a directory with a fixed number of entries. A "partition", however, was the name given to a segment of the main storage (RAM). --Jost Riedel (talk) 15:15, 1 September 2010 (UTC)
what exactly is a "boot volume"?
the term "boot volume" is used in the article, but it is not defined. -- 15:19, 12 November 2011 78.180.70.199
Volume (compression) is an unreferenced stub with content similar to Volume (computing). It could be added in a separate section, or perhaps simply just redirect. Senator2029 ➔ “Talk” 22:01, 12 July 2013 (UTC)
"Mount points have been left at defaults." What does that mean in regard to the following table ? There´s no column header, that says "mount point."
Volumes go back at least to OS/360 in the early 1960's, if not earlier. The article makes it seem that they started with MS-DOS, or some similar system. For OS/360, volumes can be either tape or disk. Even more interesting, OS/360 allows for multi-volume data sets, especially on tape, though also removable disks. This feature, and tape volumes, do not seem to have survived into MS-DOS or Windows. Note that OS/360 volumes continue through MVS and z/OS. Gah4 (talk) 21:51, 29 July 2015 (UTC)
Why is the term volume defined as it is and where does this definition come from?
Later in the article it is stated, that Windows Server 2008 and later (in #Differences between volume and partition) volume is used as a superset that includes partition as well, while the definition that a volume is a single accessible storage area with a single file system is not referenced anywhere.
The reason I ask is that I cannot find such a definition anywhere. What I can find, is, that partitions and volumes are used everywhere in articles and books about storage techniques, but not defined. An example is Mac OS X Disk Utility, where creating partitions will actually call them volumes, so they are the same (in this context at least).
Also, this statement is false:
While the first sentence might be true, the second is definitely false. A floppy disk can be partitioned, easily. Just use Linux or another operating system that lets an expert user decide what he or she wants to do, manually. The reason that floppy disks are not partitioned is that it is just not viable given the storage capacity. (Likewise it was possible to use 100MB ZIP-Disks with or without a partition table.) On the other hand, higher capacity storage devices, e.g. HDDs or SSDs, can easily as well be used without a partitioning scheme at all, again easily when using Linux. (Microsoft called this superdisk, and like it is not supported to use partitioned floppies in Windows, it is not supported to use unpartitioned USB pen drives, even though it would work easily...) So why is this not the common practice and why is it not recommended? Because, if such a storage device would be accessed from, say, Windows or another operating system than the original, it would be seens as "empty" because it lacks a partition table. In that sense a parition table is just a precaution for multi-boot-systems, telling another operating system that the disk (or a part of the disk, i.e. ore or more partitions) is actually in use by another system (hence the partition type - Windows will ignore unknown types, yet honor the fact that they're there and that they might be in use).
Another reason is, of course, "magic". Modern operating systems want to see "headers" to make automatic configuration and use possible. As such, if Linux finds a partition table, it will look for suitabel partition types. It will then search the headers of those "volumes" (actually, partitions) for further information, like LUKS headers, LVM structures or file systems. All this would be a bit harder without the partitioning struction, but it would be possible.
Windows (like macOS) also uses such "magic", thus requireing certain structures such as partition tables in the first place.

There is a link here about a merge with volume serial number, but there is no discussion here. I think merge is fine, but with one complication. OS/360 and successors use the volume serial number to keep track of disks and tapes, even NL (unlabeled)tapes. In that case, the volume serial number is only written on a sticker attached to the reel. I suspect that this defintion doesn't apply to other systems. OS/360 will request that a tape be mounted, if specified as NL will verify that the tape actually does not have a label, and then allow it to be used. One thing to know, if the tape is blank (not previously used) it will run off the reel searching for a label. In any case, NL tapes should be included in the discussion.

AFAICT (disk) drives should be the physical storage hardware, and thus only "Hard Disk 1" and "Hard Disk 2" are drives. -- 林博仁 (talk) 05:46, 25 February 2021 (UTC)
