Sometimes, external hard drive will be not showing up in Windows 7 PC due to virus infection, bad sectors, mistake, says must format, says i need to format it, says not initialized,became raw or unformatted or unallocated, unknown partition,unpartitioned . Partition shows up as raw, or convert raw to exfat ntfs fat32,or covert exfat ntfs fat32 to raw 9, Accidental Deleted or lost or changed partition by chkdsk,convert,defrag,diskcomp,diskcopy,diskpart,fdisk,format, label,subst,scandisk,sys,vol,vssadmin, and partition magic and more other unknown reasons. Windows 7 cannot detect external hard drive, so the external hard drive will not show up when you connect it to your Windows 7 PC.
Sometimes you may fail to access your external drive. You can see the drive using Windows 7 Explorer, but it shows the drive as RAW with 0 bytes of data and 0 bytes of free space. As it stated above, the function of the external hard drive is as same as internal hard drive, so its construction is also similar with normal hard drive. That means it can be separated to be many partitions by writing partition information into partition table.Data loss is an error condition in information systems in which information is destroyed by failures or neglect in storage, transmission, or processing. Information systems implement backup and disaster recovery equipment and processes to prevent data loss or restore lost data. Data loss is distinguished from data unavailability, which may arise from a network outage. Although the two have substantially similar consequences for users, data unavailability is temporary, while data loss may be permanent. Data loss is also distinct from data breach, incident where data falls into the wrong hands, although the term data loss has been used in those incidents. Data recovery is often performed by specialized commercial services that have developed often proprietary methods to recover data from physically damaged media. Service costs at data recovery labs are usually dependent on type of damage and type of storage medium, as well as the required security or cleanroom procedures. File system corruption can frequently be repaired by the user or the system administrator. For example, a deleted file is typically not immediately overwritten on disk, but more often simply has its entry deleted from the file system index. In such a case, the deletion can be easily reversed. If data loss occurs, a successful recovery must ensure that the deleted data is not over-written. For this reason — one should avoid all write operations to the affected storage device. This includes not starting the system to which the affected device is connected. This is because many operating systems create temporary files in order to boot, and these may overwrite areas of lost data — rendering it unrecoverable. Viewing web pages has the same effect — potentially overwriting lost files with the temporary html and image files created when viewing a web page. File operations such as copying, editing, or deleting should also be avoided.
If the external hard drive is physically damaged and becomes undetectable, you cannot recover lost files. Therefore, it is necessary to protect the external hard dive from being physically damaged due to any possible reason like water damage, fire damage, etc.
