Stellar Data Recovery Professional software can recover files lost due to accidental deletion, formatting, corruption, or missing partition. The software performs fast, precise, and seamless data recovery from all kinds of Windows supported storage media.
However, sometimes the software may take longer duration – extending to a few hours - for scanning a hard disk (refer to screenshot), which may be due to the following reasons:
1. Disk Volume
Larger the storage volume of the hard drive, more it is going to take time to complete the scan.
2. Bad Sectors
One of the major reason behind such delays is bad sectors - a sector on a hard drive that doesn’t respond to any read/write operation. When the software finds a bad sector, which is partially readable, it tries to get all information from such sectors. This causes the data recovery software to get stuck in certain sector, as it tries to read information from such sectors.
The interface you have used to connect the drive to PC plays an important role when it comes to data recovery. If you want to get back your data fast, use SATA III interface or USB 3.0 connectivity while using the HDD enclosure or converter cable.
Use of SATA II, SATA 1, and USB 2.0 or below can slow down the scan progress significantly, especially if the storage volume is 250GB or more.
4. Power Supply
Adequate power supply is important for a hard drive to function properly. A low input voltage can cause drive corruption. Make sure your hard drive is connected to the required power supply. If you are trying to scan a Desktop grade external drive, make sure to provide additional power to spin the larger 3.5” Desktop hard disk drives for faster read and write operations.
5. Disk Fragmentation
Fragmentation leads to excessive disk usage, heat, and poor read/write performance. It hinders the scan process, as the software struggles to read file fragments stored distant apart from each other. The header has to move quickly, and platter has to rotate at full speed continuously. This can cause overheating and potential drive failure.
If the scan is stuck for long and progress is slow due to any of the reasons mentioned above, image your hard drive.
Imaging a hard drive skips bad sectors and overcomes all other probable causes that increases scan time. You can create a virtual image of your hard drive by using Stellar Data Recovery Professional and scan the virtual disk image to recover lost files faster.
