Morning Coffee with Tracer
Tracer’s office door has started refusing to latch unless he lifts the handle slightly and gives it an encouraging shoulder tap. It has become the only security door in Florida that needs emotional support.
He has been meaning to fix it. Instead, he is standing beside it with a small cortado, gently negotiating with the latch, when his phone rings.
The caller is giving away an old printer and a computer. They have already deleted the documents, emptied the Recycle Bin, and performed what they describe as “a very confident restart.”
Then comes the important question:
“Is that enough?”
Tracer looks at the door. It remains open by one inch, apparently waiting for a pep talk.
“No,” he says. “Let’s clean the devices properly.”

Deleting a file usually removes its index entry. In plain language, the computer forgets where the file is listed, but the underlying data may remain on the storage drive until new information uses that space.
That means a deleted tax return, photograph, email export, or client document may still be recoverable with specialized software.
Emptying the Trash or Recycle Bin is not the same as securely erasing a drive.
Secure erasure, also called sanitization, is the process of making stored information difficult or impossible to recover using an appropriate method for that type of storage. The correct method depends on whether the device uses a traditional hard disk drive, a solid-state drive, flash memory, or another storage system.
The Cybersecurity and Infrastructure Security Agency explains that deletion alone may leave data behind. The UK National Cyber Security Centre also warns that ordinary deletion is often insufficient before a device is sold, donated, or reassigned.
Many modern multifunction printers, copiers, fax machines, and office scanners contain internal hard drives, solid-state drives, or flash storage.
These devices may retain:
This does not mean every printer stores every page forever. Storage capacity, retention, security settings, and device design vary by model. Inkjet printers often have little or no document storage. Business multifunction printers are more likely to include internal storage because they process scanning, copying, secure release printing, and network jobs.
Before donating or recycling a printer, read the manufacturer’s manual and search its administrator menu for terms such as:
A normal factory reset may remove network settings and user preferences without securely erasing stored documents. For highly sensitive equipment, use a qualified IT asset-disposal provider or have the internal storage professionally removed and destroyed.
Here is Tracer’s favorite surprise of the morning:
A computer sitting unplugged in a closet may still have a tiny CMOS or RTC battery.
CMOS and RTC refer to related motherboard functions. The battery helps preserve certain firmware settings and keeps the real-time clock running while the computer’s main power is disconnected.
So, yes, that old computer may be unplugged while its tiny heart is still keeping time.
But let’s correct an important misconception.
The CMOS battery does not keep the computer fully operational. It does not power the operating system, connect the computer to the internet, or allow someone to access it remotely. A breacher cannot remotely exploit the battery simply because it remains installed.
The real risks are different:
Removing the coin-cell battery is also not a secure wipe. Some firmware settings are stored in nonvolatile memory, meaning they remain even without continuous power. Wipe or destroy the storage properly, and update firmware before retirement when the device is still usable.
The closet computer is not secretly awake. It is simply preserving its clock while waiting for someone to make a careful decision.
Before starting, back up only the files you truly need. Confirm that the backup opens. Then:
Microsoft says the Clean data option takes longer but makes removed files harder to recover. Its official reset guidance also warns that this consumer process does not meet every government or industry sanitization standard.
Solid-state drives, or SSDs, store data differently from older spinning hard drives. Ordinary overwriting is not always the best method for an SSD. Use the drive manufacturer’s Secure Erase or NVMe Sanitize tool, or use a qualified recycler. Do not blindly use older hard-drive wiping tools such as DBAN on an SSD.
When the computer reaches the first Windows setup screen, stop. Do not create an account for the recipient, and never give away your old password.
Back up your important files. Sign out of Apple ID, iCloud, Messages, and other Apple services. Turn off Find My Mac and remove the computer from your Apple account.
On supported Macs, use System Settings → General → Transfer or Reset → Erase All Content and Settings.
Older Macs may require macOS Recovery and Disk Utility. The exact procedure depends on the model, processor, operating system, and storage type. Follow Apple’s current instructions for that model. After the erase and reinstall, stop at Setup Assistant.
The same principle applies: a clean setup screen is the handoff point. The recipient should create their own account.
For an iPhone, iPad, or Android device:
A factory reset is not enough if the device remains attached to your account. Activation Lock and similar protections may prevent the next owner from using it.
A wireless router may retain:
Before giving away a router or mesh system, remove it from the manufacturer’s cloud account. Delete remote-management access. Remove SIM cards and USB storage. Follow the manufacturer’s full factory-reset procedure, not merely a quick restart.
After the reset, verify that the device enters setup mode. If you reuse the same network, change the Wi-Fi password afterward. If the router is unsupported or its reset cannot be verified, recycle it through a reputable electronics program.
USB drives, external hard drives, and SD cards: Copy what you need, securely erase the media, and never donate a drive that still contains personal or business information. Moving files to the Trash is not secure erasure.
Smart TVs and game consoles: Sign out, remove payment information, unlink cloud accounts, delete saved recordings, and perform the official factory reset.
Cameras and network video recorders: Remove memory cards, delete local recordings, transfer ownership through the official account process, and delete cloud recordings. Remove every remote-access user.
NAS devices: A network-attached storage device may contain multiple drives and backups. Inventory every volume, remove accounts, and use the manufacturer’s storage-sanitization procedure. Sensitive business data belongs with a professional IT asset-disposal provider.
If a device left your control without being wiped, change related passwords from a clean device. Prioritize Wi-Fi, email, cloud storage, printer administration, router administration, and any account saved on the device.
Before the device leaves your hands:
Tracer gives the office door one final shoulder tap. This time, it latches.
The door was not haunted. It was merely tired.
Your old device may be tired too, but it is not empty simply because the screen is dark. The safest gift is a clean device, not your old data wearing a new owner’s name.
Deleting a file is not the same as securely erasing it. Printers, routers, computers, phones, cameras, and storage drives may retain information long after you stop using them. Match the sanitization method to the device, unlink your accounts, and use professional disposal when the data is sensitive.
Tracer’s pick is a written device inventory. Record the device type, serial number, storage media, account status, wipe method, and final destination. It is simple, inexpensive, and remarkably useful when a household or business has more retired electronics than anyone wants to admit.
