Benefits of Using a USB Drive for Data Recovery
There are several key advantages to using a USB drive for recovering data from a hard disk:
Portability
USB drives are small, lightweight, and extremely portable. You can carry a USB drive in your pocket and use it to boot into recovery mode on any PC. This makes it easy to access and recover data from the failed hard drive computer without moving the machine.
Bootable Environment
USB drives allow you to boot into a special recovery environment without relying on the hard drive itself. This enables you to access the hard drive partitions and file systems even if the main operating system won’t load.
Bypasses Operating System
Booting from a USB allows you to bypass the installed OS and any filesystem errors or corruption. This gives direct access to the hard drive sectors, increasing the chances of data recovery.
Contains Recovery Software
Bootable USB drives can be loaded with specialized data recovery programs and tools that you can run directly from the USB without installing anything on the computer.
Affordable
USB drives are extremely affordable and reusable. A decent 16GB USB drive costs under $10 and can be used for multiple data recovery projects.
Requirements
To recover your data using a USB drive, you will need the following:
– A USB flash drive with at least 8GB of storage space. A 16GB or 32GB drive is recommended.
– A Windows PC or Mac with administrator access.
– Backup software or bootable recovery software installed on the USB drive. Popular options include Recuva, TestDisk, Disk Drill, and Stellar Data Recovery.
– An external hard drive, NAS device, or cloud storage to recover the files to.
– Patience and time. Data recovery can be a lengthy process depending on the amount of data.
Creating a Bootable USB Recovery Drive
The first step is to create a bootable USB recovery drive that you can boot from and run data recovery software on the hard drive. Here is how to make a recovery drive:
On Windows
1. Insert your USB drive into an available USB port. Make sure important data is backed up and use a USB drive that can be erased.
2. Open the Start menu and type “Recovery Drive”
3. Select the option to create a recovery drive. Allow the process to completely format the USB drive.
4. Check the “Backup system files to the recovery drive” option and remove any other options.
5. Click Next and allow the USB drive to be formatted and configured as a recovery drive. This may take 10-20 minutes.
6. When complete, install your data recovery software of choice onto the USB drive. Many recovery apps have portable versions.
On Mac
1. Insert the USB drive and launch Disk Utility. Select the USB drive in the sidebar.
2. Click Erase at the top and choose “Mac OS Extended” format. Give it a name like “Recovery” and click Erase to format.
3. Download your data recovery app and copy the .dmg or .app file directly to the USB drive. Many have bootable Mac versions.
4. Right click on the recovery app file and select “Open” then click “Ok” to confirm opening. The software will create the necessary boot files on the drive.
The USB drive is now ready to help you recover data from a hard drive.
Booting from the USB Drive
With your bootable recovery USB drive created, follow these steps to boot from the drive on either Windows or Mac:
On Windows
1. Insert the recovery USB drive into an available port and restart the computer.
2. As the computer restarts, press F2, F8, F10, F12, or DEL to enter the BIOS or boot menu. The key varies by manufacturer.
3. Select the option to boot from the USB drive. Names may vary but look for “Removable Device” or your USB’s name.
4. Save changes and exit BIOS to boot from the USB drive. The recovery software will load.
On Mac
1. Connect the recovery USB drive and restart the Mac while holding the Option key.
2. Select the orange USB drive icon labeled “EFI Boot” to boot from the USB.
3. Your drive will load to a boot manager or GRUB menu. Select the recovery app or boot option.
You are now booted into the data recovery environment on the USB and ready to attempt recovering data from the main hard drive in the computer.
Recovering Deleted Files from Hard Drive
If you just accidentally deleted a file or formatted a drive, recoverable data likely still resides on the hard disk. Follow these steps to get deleted files back:
1. Once booted from the USB drive, open the data recovery app.
2. Select the target drive you want to recover deleted files from. This is usually the main internal hard drive of the computer.
3. Scan the drive. The software will scan and analyze the hard drive for recoverable data.
4. Preview found files. Look through the found files and select those you want to recover.
5. Choose a recovery destination. Pick an external drive or separate partition to save the recovered files to.
6. Recover the files. Once selected, the software will retrieve and restore deleted files from the hard drive to your chosen location.
Tips for Recovering Deleted Files
– Don’t install recovery software or save files back to the same drive you are recovering from. This overwrites deleted data.
– Narrow file searches by type and date filters if recovery stalled at a certain point.
– Recovering larger files like video will take longer than office documents or photos.
– If the file directory is corrupted, recover files by searching raw file signatures rather than file names.
Recovering Data from Crashed Hard Drive
If the hard drive has completely failed or has physical errors, it requires more advanced data recovery methods. Follow these steps:
1. After booting from the recovery USB, select the crashed hard drive. It may not show up normally in the file browser.
2. Scan the drive sectors directly using the data recovery app’s sector editor or disk imaging tools. This reads raw data from failing drive platters.
3. Use advanced options to manually rebuild directories, file tables, and perform deep sector scans. This finds data in corrupted operating systems.
4. Repair issues reported if the drive has filesystem errors. Data recovery apps can fix some corrupt partitions and tables.
5. Image the full hard drive before attempting data recovery if it has bad sectors. This copies usable data to a stable image file first.
6. Recover data from the stable disk image if the physical drive is unstable or damaged.
Tips for Recovering Data from Crashed Drives
– Don’t force a crashed drive to mount or change settings. This stresses failing hardware.
– Cooling a overheated drive in a freezer bag for 30 minutes can help stabilize it temporarily.
– If the drive clicks, buzzes, or grinds, it likely has physical head or platter damage. Avoid powering it up repeatedly.
– On clean mechanical failures, look into professional recovery services like DriveSavers to reconstruct drive parts in a lab environment.
Recovering Data from an External Storage Device
External hard drives and USB drives can also have deleted files or experience complete failure. Here are tips for recovering data from external devices:
– Use write protection when connecting the external drive to avoid overwriting data.
– Try connecting the external drive to a different computer if it isn’t being detected.
– Boot from a USB recovery drive instead of the external drive’s native OS.
– Remove the external drive from its enclosure and connect directly via SATA as a secondary drive if USB isn’t working.
– Use a SATA to USB adapter to hook up a bare external drive for scanning and imaging if the USB case is damaged.
– Target external media like SD cards and USB drives with file recovery apps that specialize in those devices.
Choosing the Right Data Recovery Software
With so many data recovery apps available, it can be tricky choosing the right one for your situation. Here are key factors to consider:
– Supported operating systems – Windows, Mac, Linux, etc.
– Types of drives it works on – hard disks, SSDs, USB, etc.
– File systems covered – FAT, NTFS, HFS+, EXT, etc.
– Recovery capabilities – deleted files, formatted drives, corrupted OS, lost partitions, etc.
– Advanced tools – disk imaging, partition editing, backup tools, cloning, etc.
– File previews – check files before recovering them.
– Easy to use interface – wizard modes for beginners.
– Filtering options – narrow searches by file types, dates, sizes, etc.
– Reviews and reputation – established vendors with a proven track record.
– Customer support – responsive technical assistance by phone, email, and chat.
– Price – flexible purchasing options and value for money. Avoid overly cheap software.
Our recommendation is to try multiple tools since no one program can handle every data recovery scenario. Having options increases your success chances.
Tips for Safe Data Recovery
Following proper precautions is crucial during data recovery to avoid permanent data loss:
– Always backup important data regularly to avoid relying on recovery tools alone.
– Recover deleted or lost files as soon as possible before areas are overwritten with new data.
– Create a clone or image backup of failing drives before attempting recovery procedures.
– Scan hard drives sector-by-sector instead of just free space to see all data.
– Save recovered files to a different healthy drive, not back to the damaged source disk.
– Avoid deleting, formatting, or initializing a drive that needs data recovery attempts.
– Use write protection like disk imaging software to prevent writing to the drive during recovery.
– Keep failing hard drives cool and dry. High heat causes further hardware damage.
