Leave it be. I tried earlier also to absorb that into my usable partitionable formattable territory. Ended up simply continuing to work my plan of rePartitioning, reFormating my harddrive as C & D logical drives. That little bit apparently belongs to something within the harddrive. Leave it be. 🙂

Addendum: later post by dg1261 labels this as a first cylinder reserved for the partition table…see later post by dg1261.

No, you cannot. 7.84MB is precisely the size of one cylinder* on a traditional MBR-type disk, so it’s evident you setup the partition layout as a single logical volume within a partition of “Extended” type on a MBR-type disk.** In such a scenario the first cylinder is reserved for the partition table so cannot be included in any logical volume.

It is very unfortunate that Easus persists in marking this as unallocated space. Yes, it is technically “unallocated” to any logical volume, but by displaying it as such it leads people to think they can allocate it for something when they cannot. Smarter partition managers would not display space to the user that the user cannot allocate.

As a practical matter, think about how little space you’re fretting over. 7.84MB is the size of about 7 floppy disks. It’s 1/90 of a typical CD disc, or about 0.001% of a regular DVD disc. Seriously, how much more utility would that space provide if you were able to use it?

Footnotes:

* 7.84MB = 255×63 sectors of 512 bytes/sector on most computers. HP/Compaq/Lenovo computers notably use 240×63 sectors per cylinder, or 7.38MB.

** Unlike a Primary partition, an Extended partition may contain multiple logical volumes. Microsoft refers to these logical volumes as “logical drives”, but they are part of a single partition of “Extended” type. Because of the way you setup the partition layout, there is a tad more wasted space because there are two partition tables–the primary table that defines the Extended partition and the secondary table that defines the logical volume within that partition. If you had setup the layout as a single Primary partition you would have wasted less space… but, again, think of the miniscule amount we’re talking about here. It is not worth repartitioning to reclaim such a small amount of space, so just leave it be.

dg1261, when I first started using Acronis Disk Director 10, later 11 & 12 — I wasn’t “told” by ADD this 7+MB was unusable by anyone. So, hopefully, future editions will do so.

GUG,

With a MBR disk you can have up to 4 Primary partitions (only ONE Active).
With the new GPT disk type you can have as many as you want, however Windows only allows up to 128 (should be enough?).

David,

See Using Mounted Drives here. HTH :cheers:

I looked at the link but (maybe I just did not look close enough) I still don’t know what Windows does when the 27th Basic drive goes on line. Not that I envision ever having to deal w/ that situation :p

David,

You can “mount” partition #27 to a folder in a drive with an assigned letter. ( Instructions ).

So you could have a Drive Z and with in that drive have a folder called DriveAA. You would then mount the 27th partition to that folder. Following on you could have a folder called DRIVE AB and mount the 28th partition to that folder, etc. Yes it makes the references a little longer since they would be z:DriveAA… but it would allow you to mount unlimited (of in Windows case the other 101) partitions.

I hope this makes sense and that I’ve understood what I’ve read about this feature. Unfortunately, I’m traveling and don’t have access to a machine that I can test this on. HTH :cheers:

In English its painful and annoying ‘but’ leave be and ignore it. It’s a hard drive thing and just has to be
The tech bit has all been said above, I would not suggest playing around with it thou

Unless you use Bitlocker or you do not have a GPT formated boot drive you can indeed remove or on a clean install never create the System Reserved partition. You sure don’t recover much of a modern hard drive though.
