JBOD Just a bunch of disks

Hey, as the title states, I’m amassing quite a few hard drives, and my lettering in Windows My Computer is tedious to look at and navigate around, like TV 1 (F: ) and TV 2 (G: ), all the way till the latter parts of the alphabet
so i was reading about JBOD, and figured something that can assign 1 drive letter to multiple drives would be useful, like if (F: ) accessed my 200 and 250gig drives, so that (F: ) = 428gigs total

would i be able to accomplish this without a seperate hardware controller, and if it’s capable with software, any drawbacks in using this to sort out my drives??

For what I know JBOD can be obtained only with a RAID controller, because is “de facto” a RAID mode.

In JBOD mode you sort of “merge” all your discs in a unique large drive. But an hardware RAID card is a must.

Yes, you need a controller, either on the mainboard or a PCI card. I think Windows Dynamic Discs might have something similar, but this method has some drawbacks. Similarly, a RAID array such as JBOD will mean that all the data is lost if just one drive goes down.

That’s why RAID 1, 5 etc. has a purpose.

Windows XP PRO can do this in software without a hardware raid controller.
However, I’d recommend a hardware controller. It’ll be faster & less prone to dying for no apparent reason …

Dynamic disks and volumesDynamic disks provide features that basic disks
 do not, such as the ability to [b]create volumes that span multiple disks
 [/b](spanned and striped volumes), and the ability to create fault tolerant
 volumes (mirrored and RAID-5 volumes). All volumes on dynamic disks are
 known as dynamic volumes.

There are five types of dynamic volumes: simple, spanned, striped, mirrored,
 and RAID-5. Mirrored and RAID-5 volumes are fault tolerant and are
 available only on computers running Windows 2000 Server, Windows 2000
 Advanced Server, Windows 2000 Datacenter Server, or Windows XP.
 However, you can use a computer running Windows XP Professional to
 create mirrored and RAID-5 volumes on these operating systems.

Regardless of whether the dynamic disk uses the master boot record (MBR)
 or GUID partition table (GPT) partition style, you can create up to 2,000
 dynamic volumes per disk group, although the recommended number of
 dynamic volumes is 32 or less per disk.

For information about managing dynamic volumes, see Manage dynamic

Limitations of dynamic disks and dynamic volumes
When using dynamic volumes, the following limitations apply:

When installing Windows XP Professional. If a dynamic volume is created
 from unallocated space on a dynamic disk, you cannot install Windows XP
 Professional on that volume. However, you can extend the volume (if it is a
 simple or spanned volume). This setup limitation occurs because Windows
 XP Professional Setup recognizes only dynamic volumes that have an entry
 in the partition table. 
Portable computers. Dynamic disks are not supported on portable
 computers, removable disks, detachable disks that use Universal Serial Bus
 (USB) or IEEE 1394 (also called FireWire) interfaces, or on disks connected
 to shared SCSI buses. If you are using a portable computer and right-click a disk in the graphical or list view in Disk Management, you will not see the
 option to convert the disk to dynamic. 
Dual-boot computers. Dynamic volumes (and the data they contain) cannot
 be accessed by, or created on, computers running MS-DOS, Windows 95,
 Windows 98, Windows Millennium Edition, Windows NT 4.0, or Windows XP
 Home Edition that are configured to dual-boot with Windows XP
 Professional or Windows XP. If you want computers running these operating
 systems to be able to access the data, store the data on basic volumes
 instead. For information about basic volumes, see Basic disks and volumes. 
When extending a volume. If a basic volume is converted to dynamic (by
 converting a basic disk to dynamic), it may or may not have an entry in the
 partition table depending on whether that volume was a system or boot
 partition. If the converted volume was a system or boot partition it retains
 an entry in the partition table. You can install Windows XP Professional on
 the volume, but you cannot extend it. If the converted volume was not a
 system or boot volume it does not have an entry in the partition table. You
 cannot install Windows XP Professional on the volume, but you can extend
On Windows 2000, volumes converted from partitions have an entry in the
 partition table. On Windows XP Professional, volumes converted from
 partitions do not have an entry in the partition table unless the partitions
 were system or boot partitions. In Disk Management, you can see if a
 volume has an entry in the partition table by right-clicking the volume. If
 Extend Volume is disabled, the volume has an entry in the partition table.

You can install Windows XP Professional only on simple and mirrored dynamic
 volumes, and these volumes must have entries in the partition table (which
 means that these volumes were system or boot volumes).

I’d recommend against JBOD, period. All the risks inherent in a vanilla striping array with no performance gain.

I agree :iagree:

Why don’t you just remove the drive letters from the partitions & then mount them in an empty NTFS folder on your main HD?

I recently had the same problem, so I did this :wink:

As you can see …
D_Store, Main(ALT WINXP), S1_Store, S2_Store & Super_Store are all different HD partitions mounted on my Main OS HD.

It’s freed up 5 drive letters.

i originally planned to use JBOD so that I wouldn’t have to go thru a bunch of drives to see everything i got…like drive E for music a-l and drive F for music m-z. I’d rather open My Computer, and go into one drive, and see everything, so that it would be C for OS, D for Everything (music/apps/movies).
somehow it’s like connecting to a couple ftp’s to find something, whereas i want to connect to one massive ftp that has all i need.

any way to accomplish this??

Mount F: in your Music (A-L) folder in the FTP shared folder.
Mount E: in your Music (M-Z) folder in the FTP shared folder.
Mount D: in your everything folder in the FTP shared folder.
