Error 0x8007045D in Windows: 'The request could not be performed due to an I/O device error'

Error 0x8007045D in Windows means that the read/write operation cannot be completed due to an I/O device error. It most commonly appears when:

• copying/moving files to a disk, flash drive, or external HDD/SSD;
• installing Windows/programs (especially from a USB drive);
• updating Windows (less frequently, but can occur with disk or file system issues).

If there are important data on the disk and the error persists — first make a backup, and only then run lengthy checks.

Main Causes

1. Media issues: degradation of HDD/SSD, damaged sectors, controller failure.
2. USB issues: faulty cable, unstable port, power, hub.
3. Corrupted file system: NTFS/exFAT errors, sudden disconnections.
4. Corrupted data: a specific file/archive/image is read with errors.
5. System errors (if it appears on the system disk): driver failure, Windows image errors.

Quick Diagnosis (2–5 minutes)

1) Clarify where the error occurs

• Only on one file → likely, the file is corrupted.
• On any files on one media → suspicion on the media/port/file system.
• On system disk C: → proceed with caution, check SMART and the system.

2) Check the event in the log

1. Win + R → eventvwr.msc
2. Windows Logs → System
3. Filter by sources: Disk, Ntfs, storahci, iaStorA, volmgr

If you see errors like “The device has a bad block” or “I/O operation failed” — this is a strong signal of problems with the disk/connection.

Solution 1: Check cable/port/power (most common)

Applicable if the error occurs while working with flash drives/external disks/card readers.

• Connect the device to another USB port (preferably on the back panel of the PC).
• Remove the USB hub/extender.
• Replace the cable (especially micro-USB/USB-C on external disks).
• For external 2.5" HDDs, check the power: sometimes a Y-cable or another port helps.

If the error disappears after changing the port/cable — the cause was an unstable connection.

Solution 2: Run CHKDSK to check the file system and sectors

Important: /r may take a long time. It's better to copy important data first from a problematic disk.

Open Command Prompt as administrator and execute:

chkdsk X: /f /r

Where X: is the letter of the problematic disk (e.g., D: or E:).

• /f fixes file system errors
• /r searches for bad sectors and attempts to recover readable data

If the check on C: asks for a reboot — agree.

Solution 3: Check SMART (to understand if the disk is "dying")

If the error persists, check SMART:

• CrystalDiskInfo (convenient for quick assessment)
• Manufacturer's utility for SSD/HDD (Samsung Magician, WD Dashboard, SeaTools, etc.)

What to watch out for:

• Reallocated Sectors / Pending Sectors
• Uncorrectable Errors
• Sudden drop in "health"

If SMART shows warnings — urgently back up data and plan to replace the disk.

Solution 4: Restore system files (if the error occurs during updates/installations)

Open the terminal/command prompt as administrator:

sfc /scannow

Then (Windows 10/11):

DISM /Online /Cleanup-Image /RestoreHealth

Restart the PC and repeat the operation (update/install/copy).

Solution 5: Copy data "carefully" using Robocopy

If you need to extract data from an unstable media, Robocopy sometimes performs better than Explorer:

robocopy "D:\source" "E:\backup" /E /R:3 /W:2 /COPY:DAT /DCOPY:DAT

• /R:3 — 3 retries on error
• /W:2 — 2 seconds pause

If read errors are widespread — this is a sign of problems with the media, not with Explorer.

Useful Tips

• If the error occurs during installation from a flash drive: rewrite the installation flash drive (different USB port, different media, different ISO image).
• For external disks: check if the device is overheating.
• If the problem is only with one archive/ISO: check the checksum (SHA256/MD5), download it again.

When to stop experimenting and start saving data

Stop and proceed to backup/recovery if:

• CHKDSK finds many bad sectors;
• SMART shows degradation;
• the disk periodically disappears from the system;
• clicking/grinding noises are heard (HDD).

Conclusion

0x8007045D is almost always an I/O issue: media, port, cable, power, or file system. Start with the simple (port/cable), then check the disk (CHKDSK + SMART), and only after that deal with system recovery (SFC/DISM) if the error is related to updates or installations.
