Perfect — good job. While the Compress-Archive run finishes, here are safe, simple checks and small tests you can run (one‑line commands to paste) to verify the ZIP and then move it off the PC. I’ll stay with you while you run any of these.
1) Quick status — does the ZIP exist and how big is it?
Paste this single line:
Get-Item "C:\RecoveredBackup\DriveBackup.zip" | Select-Object Name, @{N='Size(GB)';E={[math]::Round($_.Length/1GB,2)}}, LastWriteTime
If it returns nothing yet, the ZIP hasn’t finished creating.
2) List the ZIP contents (safe — doesn’t extract anything)
This shows file names and sizes inside the archive:
Add-Type -AssemblyName System.IO.Compression.FileSystem; [System.IO.Compression.ZipFile]::OpenRead('C:\RecoveredBackup\DriveBackup.zip').Entries | Select FullName, @{N='SizeKB';E={[math]::Round($_.Length/1KB,2)}} | Format-Table -AutoSize
3) Spot‑check a single file from the ZIP (extract one file to verify it opens)
Create a temporary test folder and extract the first matching entry (example looks for any file in DCIM — change the pattern if you prefer):
New-Item -ItemType Directory -Path "C:\RecoveredBackup\TestExtract" -Force; Add-Type -AssemblyName System.IO.Compression.FileSystem; $z=[System.IO.Compression.ZipFile]::OpenRead('C:\RecoveredBackup\DriveBackup.zip'); $e=$z.Entries | Where-Object { $_.FullName -like '
DCIM' } | Select-Object -First 1; if($e){ $e.ExtractToFile((Join-Path 'C:\RecoveredBackup\TestExtract' $e.Name), $true); Write-Output "Extracted: $($e.FullName)"; } else { Write-Output "No DCIM entry found to test." }
Then open the extracted file in File Explorer (C:\RecoveredBackup\TestExtract) to confirm it opens.
4) If you want to test integrity with 7‑Zip (only if installed)
& "C:\Program Files\7-Zip\7z.exe" t "C:\RecoveredBackup\DriveBackup.zip"
5) Move or copy the ZIP to a safe second location (recommended)
- If you have another external drive (say E, COPY (preferable to MOVE until you verify):
Copy-Item "C:\RecoveredBackup\DriveBackup.zip" -Destination "E:\DriveBackup.zip" -Verbose
- If you only have cloud (OneDrive), you can move/copy the ZIP into your OneDrive folder (but that requires upload time/bandwidth).
6) After verifying the ZIP
- Keep the original C:\RecoveredBackup files until you’ve verified the ZIP(s) open and extract correctly. Only delete originals after you’ve confirmed the archive(s) and made a second copy offsite or to another drive.
7) If anything errors or the archive is incomplete
- Paste the last lines of the Compress-Archive error output or run:
Get-Content "C:\RecoveredBackup\robocopy-full-log.txt" -Tail 30
(or open the log with Notepad)
I’ll interpret any failures and recommend the next step (read‑only recovery / image / chkdsk only after backups).
Would you like to:
- Run the list command now to see ZIP contents? (type “List”)
- Run the single-file extract test? (type “Test”)
- Copy the ZIP to another drive now? (type “Copy” and tell me the drive letter)
I’ll wait for which you want and guide the exact pasteable command.
