exFAT file system (Extended File Allocation Table)

DATARECOVERYUNION.COM15 years ago4 years ago14 mins

exFAT (Extended File Allocation Table) is a file system designed and patentend by Microsoft and released in all versions of Windows, starting with Windows Server 2008. In addition Microsoft has released an update for Windows XP and Windows Server 2003, to add support for exFAT formatted drives.

exFAT is considered the successor to the FAT16 and FAT32 file systems. exFAT has a number of advantages and disadvantages over NTFS and FAT32. It has a theoretical maximum disk size up to 64 ZB (Zettabytes) or 64 billion terabytes, versus a 32 GB maximum under a FAT32 partition. It also allows for up to 2,796,202 files per directory, increased from 65,536 under FAT32. Finally exFAT supports Sector sizes between 512 and 4k, and a cluster size of 32 MiB (mebibyte, large megabyte).

Advantages:

Scalability to large disk sizes: 64 ZiB theoretical max, 512 TiB recommended max, raised from the 2 TiB limit of FAT32 partitions. Note that the built-in Windows XP format utility limits new FAT32 partitions to 32 GiB.
Sector size between 29 (512) and 212 (4,096) bytes.
Cluster size up to 32 MiB.
File size limit of 64 ZiB (512 TiB recommended max), raised from close to 4 GiB in FAT32.
Free space allocation and delete performance improved due to introduction of a free space bitmap
Support for up to 2,796,202 files per directory, increased from 65,536
Support for access control lists (not supported yet in Windows Vista SP1)
Support for TFAT, a transactional file system standard (optionally WinCE activated function)
Provision for OEM-definable parameters to customize the file system for specific device characteristics
Support for UTC timestamps (starting with Vista SP2)
Timestamp granularity of 10 ms (better than previous FAT versions’ 2 s, but worse than NTFS’s 100 ns)

Disadvantages:

Windows XP and Windows Server 2003 users must have Service Pack 2 or later and install an update to support exFAT
Windows Vista must be Service Pack 1 or later for exFAT support
Devices formatted using exFAT cannot be read by any version of Windows prior to Windows XP or by any version of DOS or OS/2 (unless emulated as otherwise).
Devices using exFAT are unable to use Windows Vista’s ReadyBoost capability (Windows 7 adds support for ReadyBoost on exFAT formatted drives and enables a larger ReadyBoost cache due to the removal of the 4GB file size limit of FAT32)
Microsoft has not released the official exFAT file specification, and a license from Microsoft is required in order to make and distribute exFAT implementations
Limited or no support outside PC environment at present — most current consumer electronics, such as televisions and A/V receivers, can only handle previous FAT versions (this may change with the new SDXC cards and Memory Stick XC requiring exFAT)

What is the difference between a primary and extended hard drive partition in Windows

DATARECOVERYUNION.COM15 years ago4 years ago12 mins

A hard drive can be divided into primary and extended partitions. Partitions function as physically separate storage units. This allows you to separate different types of information, such as user data on one partition and applications on another. A hard drive can contain up to four primary partitions, or up to three primary partitions and one extended partition, for a maximum of four partitions.

There can be only one extended partition on a hard disk, so you should include all remaining free space in the extended partition. Unlike primary partitions, you don’t format extended partitions or assign drive letters to them. You divide extended partitions into segments. Each segment is a logical drive. You assign a drive letter to each logical drive and format it with a file system.

How to Access Motherboard BIOS?

DATARECOVERYUNION.COM15 years ago4 years ago04 mins

The BIOS is a program pre-installed on computers (with the exception of Macs) that the computer uses to start up. The CPU accesses the BIOS before the operating system is loaded. The BIOS then checks all your hardware connections and locates all of your devices. If everything is OK, the BIOS loads the operating system into the computer’s memory and finishes the boot-up process.

Some of the most common single key commands are:

F1, F2, ESC and DEL.

Some of the most common key combinations are:

CTRL+ALT+ESC, CTRL+ALT+DEL, or CTRL+ALT+INS.

How to configure a WD EIDE hard drive using the Alternate Jumper Settings?

DATARECOVERYUNION.COM15 years ago4 years ago04 mins

When NOT to use Alternate Jumper Settings:

* If you are running Windows 2000/XP/Vista.

* If the system can boot with just one jumper on the drive without locking up.

* If the drive is installed on an IDE controller card that is providing support to access the full drive capacity.

When to use Alternate Jumper Settings
The most common scenario when a drive should be configured with the Alternate Jumper Settings is when the system hangs up or freezes upon boot up after auto-detecting all IDE devices. The reason for this error is because the drive capacity is larger than what the system can support.

What happens after the drive is configured with the Alternate Jumper Settings
The full capacity of the drive is not recognized. In order for the system to boot properly, the BIOS will recognize smaller drive capacity. Depending on your BIOS, your drive will recognize one of the following sizes: 2.1GB, 8.4GB, 32GB.

Configuring a single (alone on the IDE cable) drive with the Alternate Jumper Settings
If you are connecting your drive as the only IDE device on the cable, place the jumper shunts on pins 3 & 4 and 5 & 6. Connect the drive to the black connector at the end of the cable.

Configuring a primary or dual Master drive with the Alternate Jumper Settings
If you are connecting your drive as the Master drive on the cable with another IDE device, place the jumper shunts on pins 1 & 2 and 5 & 6. Then configure the jumper on the other IDE device as Slave. Connect the Master drive to the black connector at the end of the cable and the Slave device to the gray connector located at the middle of the cable.

Configuring a secondary or dual Slave drive with the Alternate Jumper Settings
If you are connecting your drive as the Slave drive on the cable with another IDE device, place the jumper shunts on pins 1 & 2 and 3 & 4. Then configure the jumper on the other IDE device as Master. Connect the drive to the gray connector at the middle of the cable and the other IDE device to the black connector located at the end of the cable.

The difference between WD Desktop edition and RAID (Enterprise) edition hard drives

DATARECOVERYUNION.COM15 years ago4 years ago03 mins

Western Digital manufactures desktop edition hard drives and RAID Edition hard drives. Each type of hard drive is designed to work specifically as a stand-alone drive, or in a multi-drive RAID environment.

If you install and use a desktop edition hard drive connected to a RAID controller, the drive may not work correctly. This is caused by the normal error recovery procedure that a desktop edition hard drive uses.

Note: There are a few cases where the manufacturer of the RAID controller have designed their drives to work with specific model Desktop drives. If this is the case you would need to contact the manufacturer of that enclosure for any support on that drive while it is used in a RAID environment.

When an error is found on a desktop edition hard drive, the drive will enter into a deep recovery cycle to attempt to repair the error, recover the data from the problematic area, and then reallocate a dedicated area to replace the problematic area. This process can take up to 2 minutes depending on the severity of the issue. Most RAID controllers allow a very short amount of time for a hard drive to recover from an error. If a hard drive takes too long to complete this process, the drive will be dropped from the RAID array. Most RAID controllers allow from 7 to 15 seconds for error recovery before dropping a hard drive from an array. Western Digital does not recommend installing desktop edition hard drives in an enterprise environment (on a RAID controller).

Western Digital RAID edition hard drives have a feature called TLER (Time Limited Error Recovery) which stops the hard drive from entering into a deep recovery cycle. The hard drive will only spend 7 seconds to attempt to recover. This means that the hard drive will not be dropped from a RAID array. While TLER is designed for RAID environments, a drive with TLER enabled will work with no performance decrease when used in non-RAID environments.
