There are many kinds of hard drive problems but most of them can be divided into software failure and hardware failure. Look at this:
Software failure:
1. Desktop, laptop computer data error recovery, and the zoning mistakenly delete data format data recovery, reshipment system "my documents", the folder on the desktop, the documents, photos, after missing data recovery. Partition tip not formatting, partition attribute RAW change, partition capacity into 0 bytes, file takes up capacity, opens the folder for empty, indicating that the file or directory structure damage and unable to read, I/O error, error parameters can't read; Mobile hard hint to delay the failure, partition RAW format into recovery; Division into not assigned space or become undistributed space; Hard disk initialized, division into dynamic disk, folders into 000, data redundancy error, the hard drive was not formatting, partition can not open.
2. Lenovo desktop, laptop, lenovo TCL desktops, IBM, SONY, asus laptops, etc will bring the system restore CD, a key recovery into a division. All other division can be removed formatted data recovery. Laptop may loss all data after a key recovery, laptop lost division after a key recovery, and a key recovery system will become a division such as SONY, Lenovo, etc. And it is hard to retrieve deleted files from hard drive.
3. Use the GHOST installation system, cover D, E plate, and the other the system disk data recovery. GHOST installation system wrongly choose DISK FROM IMAGE caused all partitions hard drive for lost, become a partition, GHOST installation system, wrong choose "will be hard drive fast into four points" option. Hard disk is divided into four new division, the original hard disk data lost all partitions data recovery.
4. Use zoning magician PQ software error, accident causes such as power operation failure, the original partition damage, unable to read, indicating that the disk format data recovery, and not hint: the file or directory structure damage and unable to read error data recovery, double click dish to be when tip: parameter wrong data recovery.

7. Disk partition appear not format error, check that RAW format attributes for RAW or system. Available space for 0
Hardware failure:
1. hard disk, mobile hard disk was cast off the after thecrashed sound, slow boot crashed, read dish slow; Desktops, laptops can't normal powered up, tip can't find hard disk. Hard disk deny, mobile hard disk can't identify; Mobile hard not to read; Move hard disk can't identify;
2. Computer can recognize move hard disk, double click the computer to crash or operation is slow.
3. Digital partner can't boot, suggested that "can't find storage equipment".
