How to Use East-Tec DisposeSecure to Permanently Delete FilesEast-Tec DisposeSecure is a dedicated file-shredding utility designed to remove files and traces of activity from Windows systems so they cannot be recovered by typical data-recovery tools. This guide explains how DisposeSecure works, when to use it, how to configure it safely, step-by-step instructions for common tasks, and best practices to ensure your deleted data stays gone.
What DisposeSecure does and how it works
DisposeSecure overwrites data on disk multiple times and removes references to files so that common recovery tools cannot restore them. Key techniques include:
- File shredding: Overwrites file contents with patterns (zeros, random data, or secure overwrite standards) before deleting the file record.
- Free-space wiping: Overwrites unallocated disk space so remnants of previously deleted files are removed.
- Wiping system traces: Removes traces like temporary files, recent-file lists, browser caches, and other artifacts that can reveal activity.
- Multiple overwrite passes: Supports configurable pass counts and overwrite patterns to balance speed vs. security.
When to use DisposeSecure
Use DisposeSecure when you need to protect sensitive information from recovery, including:
- Before disposing, donating, or selling a PC or storage device.
- When you handle financial, legal, health, or personally identifiable information.
- After uninstalling apps that may leave confidential data behind.
- When complying with internal data-retention or privacy policies.
Do not use shredding for files you may later want to recover. Overwritten files are unrecoverable.
Preparations and precautions
- Backup anything important you might need later. Once shredded, data cannot be restored.
- Verify you have administrative privileges — some operations require them.
- Close applications that might lock files you intend to shred.
- If wiping system drives (C:), consider using bootable media or confirm DisposeSecure’s support for secure system-drive operations. Wiping the system drive from a running OS can be limited or impossible for files in use.
- Understand the difference between quick deletes (irreversible) and full-disk or free-space wipes (time-consuming).
Installation and initial setup
- Download the latest DisposeSecure installer from a trusted source (official site). Avoid third-party bundled installers.
- Run the installer and follow on-screen instructions. Accept the EULA if you agree.
- Launch DisposeSecure. On first run, check settings/preferences for overwrite methods, number of passes, and logging options.
Common settings to configure:
- Overwrite method: choose between single-pass random, DoD 5220.22-M, Gutmann (35 passes), or custom patterns. Fewer passes = faster; more passes = higher assurance.
- Wipe temporary files and recycle bin on schedule (if available).
- Exclude specific folders if you want them left untouched.
Step-by-step: Permanently delete a single file or folder
- Open DisposeSecure.
- Navigate to the “Shred Files” or equivalent tab.
- Click “Add” or drag-and-drop the file(s)/folder(s) into the program window.
- Choose the overwrite method and number of passes. For most users, DoD 3-pass (a common balance of speed and security) is sufficient. For maximum paranoia choose Gutmann (35 passes) but expect long runtimes.
- Confirm you want to shred and click “Start” (or “Shred Now”).
- Wait for the process to complete. DisposeSecure will overwrite the file data and then remove the file entries.
Step-by-step: Wipe free space
Wiping free space removes remnants of previously deleted files:
- In DisposeSecure, find the “Wipe Free Space” or “Erase Free Space” option.
- Select the drive/partition to wipe (for example, C:, D:).
- Choose overwrite method and passes. Note: wiping large partitions may take hours.
- Start the operation and wait. Don’t power off or interrupt mid-process.
- When finished, the tool will report completion and any logs if enabled.
Step-by-step: Wipe system traces and application traces
- Open the “System Trace Cleaner”/“Privacy Cleaner” module (naming varies by version).
- Select the categories to clean: Recycle Bin, temp files, browser caches, recent documents, event logs, index files, etc.
- Optionally run a scan first to view what will be removed.
- Start the cleaning operation. Review logs if you want to confirm what was removed.
Using DisposeSecure on external drives and USB sticks
- Connect the external drive.
- Choose the “Shred” or “Wipe” target and select the external device/partition.
- For full device wiping (to sanitize before disposal), use full-disk overwrite rather than per-file shredding.
- For SSDs, be cautious: overwriting may not guarantee unrecoverability due to wear-leveling. Prefer manufacturer secure-erase tools or hardware encryption + crypto-erase for SSDs.
SSDs and modern storage considerations
- Traditional shredding overwrites physical sectors; SSD controllers remap sectors, so overwritten writes may not target the original NAND cells. For SSDs:
- Use the drive manufacturer’s secure-erase utility or ATA Secure Erase command where possible.
- If the SSD supports hardware encryption, issuing a crypto-erase (destroying the encryption key) is fast and effective.
- DisposeSecure’s free-space wiping may still help, but cannot guarantee full physical overwrite on all SSDs.
Scheduling and automation
- If you regularly need to clear traces, use DisposeSecure’s scheduling feature (if available) to run privacy cleans at intervals.
- Configure email or log reports if supported to monitor automated runs.
Verifying deletion
- After shredding, avoid using normal recovery tools expecting results. To test, you can run a file-recovery utility before shredding to ensure the file is theoretically recoverable and then again after shredding to confirm it is gone.
- For critical cases, consider third-party verification services or forensic analysis (costly).
Logs and audit trails
- DisposeSecure can keep logs of what it erased. If you need an audit trail, enable logging before running operations. Be aware logs may themselves contain sensitive info — protect or securely delete logs when necessary.
Troubleshooting common issues
- Files in use / locked: close the program using the file, or use Windows Safe Mode or a bootable environment to shred system files.
- Insufficient permissions: run DisposeSecure as Administrator.
- Long runtimes: reduce passes or choose a faster overwrite method if time is limited (balance security needs).
- SSD unrecoverability concerns: use manufacturer tools as noted above.
Alternative and complementary measures
- Full-disk encryption (BitLocker, VeraCrypt) before use — if already encrypted, securely erasing the key renders data unreadable without needing full overwrite.
- Physical destruction for highly sensitive media (e.g., shredded platters, incineration) when legal/organizational policies demand it.
- Manufacturer secure-erase utilities for SSDs and USB NAND-based media.
Summary checklist (quick reference)
- Backup important files.
- Choose appropriate overwrite method (DoD 3-pass is a common compromise).
- Close apps and run as Administrator.
- Shred files or wipe free space as needed.
- Use manufacturer secure-erase for SSDs when possible.
- Enable logging if you need an audit trail.
