Why Is My Data Recovery Scan Stuck or Taking Too Long

TL;DR:

A data recovery scan is often progressing slowly rather than completely frozen due to bad sectors, large drive capacity, or unstable connections, which you can verify by checking if the scanned sector counts or elapsed time continue to update.
    ● To resolve sudden speed drops or stalls, connect the storage device directly to the computer bypassing USB hubs, replace weak cables, and close disk-intensive background applications like antivirus scans or cloud sync.
    ● If the drive exhibits physical symptoms like clicking sounds, repeated disconnects, or read errors, stop the scan immediately and create a disk image or clone first to avoid stressing unstable hardware.
    ● If progress remains unchanged for a long period with no disk activity, halt the process and restart with a narrower target such as a specific folder or file type, or utilize a tool like Recoverit Data Recovery to isolate the data and save results to a separate healthy storage device.

A data recovery scan may appear stuck when the storage device is slow to read, unstable, very large, or affected by bad sectors. Scan speed can also drop because of low system resources, connection problems, file system damage, or security software interfering with disk access. If counters still update, the scan may be slow rather than frozen.

Step 1
Check whether scan progress is still changing. If found files, scanned sectors, elapsed time, or disk activity continue to update, the scan may still be running.
Step 2
Keep the storage device connected directly to the computer. Replace weak USB hubs, loose cables, or unstable adapters, especially for external drives and memory cards.
Step 3
Close heavy background tasks. Antivirus scans, cloud sync, backup tools, and other disk-intensive programs can slow recovery scans.
Step 4
Check drive condition if possible. Clicking sounds, repeated disconnects, read errors, or long stalls around damaged areas can indicate hardware trouble rather than a software issue.
Step 5
Stop the scan only if progress remains unchanged for a long period and disk activity has ended. Restarting with a narrower target, such as a folder, file type, or partition, can reduce scan time.

Common Issues and Fixes

Issue	Likely cause	Fix
Scan appears frozen	Very large drive or deep scan mode	Wait longer and watch scanned sector counts instead of the time estimate.
Deep scan runs for many hours	Bad sectors, unreadable areas, or heavy fragmentation	Reduce repeated retries if the tool allows it, or create a disk image first if the drive seems unstable.
Scan speed suddenly drops	USB hub, failing cable, weak power, or damaged area on the drive	Connect the device directly and use a known-good cable or power source.
Scan stops at one percentage	Damaged file system or corrupted partition map	Restart only if activity has fully stopped, then scan the specific partition or use another scan mode.
Computer becomes unresponsive	Low RAM, high disk load, or multiple tools accessing the same drive	Close other applications and avoid using the same drive for active tasks during scanning.

Quick Tips

Keep these points in mind while scanning:

Time estimates during recovery are often inaccurate. Progress counters are usually more reliable than the remaining-time display.
A drive with physical symptoms may worsen during repeated scans. Important data may justify a professional diagnosis before further attempts.
Writing new data to the affected drive can reduce recovery chances, especially after deletion or formatting.
Encrypted, network, or heavily fragmented storage can scan more slowly than standard local drives.

💡Protip:

If a scan stalls on a drive with clicking sounds, disconnects, or read errors, stop repeated full scans and create a disk image or clone first if possible. Scanning a copy is safer than repeatedly stressing unstable hardware.
