Windows has countless drive cloning programs available, each with their own strengths and weaknesses. It's almost impossible to pick the perfect one, but if you have a drive to clone, we recommend starting your search with DriveImage XML. DriveImage XML's biggest advantage over other cloning apps is that you don't have to reboot your computer to run the cloning process.

It can "hot image" your drive so you can start cloning while you keep working. Also, while it isn't the most advanced cloner on the market, it can do pretty much any basic cloning task in one simple program which is surprisingly uncommon in some other apps —you can clone a disk to another disk, copy a disk to an image, or clone individual partitions. Since it's designed for backup, you can also do scheduled, incremental backups as well, and even restore one of those images from a live CD if your computer won't even boot.

DriveImage XML is far from perfect. While it gets the job done, it's a little ugly, and not the most user-friendly app on the market. The live CD creation is especially difficult. It works great as a simple drive cloner for migrating data, but if you're going to use it for regular backup, you'll want to try burning that live CD before you start relying on it.

If you want something a bit more user-friendly, you'll probably have to shell out for something like Acronis True Image, but for regular cloning jobs, DriveImage XML does the job as well as anyone else—and with no rebooting required.

As we said before, there are a ton of different cloning apps for Windows, and they all do certain things a little differently. When it comes down to it, it's hard to pick the "best cloning app"—you really need to search for the best cloning app for the job. Here are some of our favorite alternatives. Acronis True Image is a great program if you're using drive cloning as your main backup utility. If you're looking for a great backup system, it'll do the job, but if you just want to clone some drives, it's probably overkill.

That said, if you're running a Western Digital drive, you can snag it for free from WD's web site. Clonezilla is a fantastic live CD for advanced cloning jobs.

In fact, we talked about it in our data migration guideand barely scratched the surface of everything it can do. It isn't very user-friendly, but if you're an advanced user that has advanced needs, it's a great tool. EaseUS Partition Master is my personal favorite of the bunch. It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform a lot of tasks at once, instead of just cloning drives.

You can move partitions around, resize them, defragment, and more, along with the other tools you'd expect from a cloning tool. It won't hot image your drive, and if you want to create an image instead of clone to a new disk, you'll have to use their separate imaging toolbut together they give you almost everything you could need and they're perfect for migrating your data to a smaller drive, like an SSD.

Again, this is far from a comprehensive list, but these are some of the best apps we'd recommend checking out.

This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread.In computing, a rigid disk block RDB is the block on a hard disk where the Amiga series of computers store the disk's partition and filesystem information. Instead it points to a linked list of partition blocks, which contain the actual partition data. The partition data includes the start, length, filesystem, boot priority, buffer memory type and "flavor", though the latter was never used.

Because there is no limitation in partition block count, there is no need to distinguish primary and extended types and all partitions are equal in stature and architecture. Furthermore, its position is not restricted to the very first block of a volume, instead it could be located anywhere within its first 16 blocks.

Thus it could safely coexist with a master boot record, which is forced to be found at block 0. Nearly all Amiga hard disk controllers support the RDB standard, enabling the user to exchange disks between controllers. From Wikipedia, the free encyclopedia. Redirected from Rigid Disk Block.

Block (data storage)

You can help Wikipedia by expanding it.This chapter describes the nature of and relationships among the logical storage structures in the Oracle server. It includes:. Oracle allocates logical database space for all data in a database. The units of database space allocation are data blocks, extents, and segments. At the finest level of granularity, Oracle stores data in data blocks also called logical blocksOracle blocksor pages. One data block corresponds to a specific number of bytes of physical database space on disk.

The next level of logical database space is an extent. An extent is a specific number of contiguous data blocks allocated for storing a specific type of information. The level of logical database storage above an extent is called a segment. A segment is a set of extents, each of which has been allocated for a specific data structure and all of which are stored in the same tablespace.

For example, each table's data is stored in its own data segmentwhile each index's data is stored in its own index segment. If the table or index is partitioned, each partition is stored in its own segment.

Oracle allocates space for segments in units of one extent. When the existing extents of a segment are full, Oracle allocates another extent for that segment. Because extents are allocated as needed, the extents of a segment may or may not be contiguous on disk. A segment and all its extents are stored in one tablespace.

Within a tablespace, a segment can include extents from more than one file; that is, the segment can span datafiles. However, each extent can contain data from only one datafile.

Although you can allocate additional extents, the blocks themselves are allocated separately. If you allocate an extent to a specific instance, the blocks are immediately allocated to the free list. However, if the extent is not allocated to a specific instance, then the blocks themselves are allocated only when the high water mark moves. The high water mark is the boundary between used and unused space in a segment.

What is the significance of the file system block size? So if my application wants to read say 16 bytes at offset then a 4K block starting from offset will be read? You are right. The block size is the unit of work for the file system. Every read and write is done in full multiples of the block size. The block size is also the smallest size on disk a file can have. If you have a 16 byte Block size,then a file with 16 bytes size occupies a full block on disk.

The book "Practical file system design" states:. Normally when you have to deal with files in programming you should use Stream abstraction. Block size on fs refers to mapping disk surface; minor the size of the single block major the number of blocks and so the elements in the table that keeps information on allocation of files. So OS's so can map file on disk discretely based on block size and have a smaller "map of files".

As I know this doesn't affect stream abstraction in API's of programming language. Learn more. File system block size Ask Question. Asked 8 years, 3 months ago.
