Can You Recover More Data From an Old 2GB microSD Card?
Possibly, but the remaining space is not automatically recoverable just because OpenSuperClone labels it non-trimmed or non-scraped. In this r/datarecovery case, an old 2GB microSD card could only be imaged to about 0.51GB before reads became extremely slow or the USB 3.0 reader dropped offline. The user already recovered 167 damaged photos from that partial image, so the first priority is to keep that image and the OpenSuperClone project/log safe.
Do Non-Trimmed and Non-Scraped Mean the Rest Is Lost?
No. They are recovery states, not final loss verdicts. In the cloning process OpenSuperClone is based on, failed blocks from the earlier copy phases are marked non-trimmed; trimming narrows those failed regions, and remaining difficult areas become non-scraped before sector-by-sector scraping is attempted. Only sectors that continue to fail after those later attempts are treated as bad. See the OpenSuperClone/HDDSuperClone operation notes.
Protect What You Already Have
Do not overwrite the 0.51GB image or start a fresh clone that discards the existing progress log. Work on copies of the image when testing file recovery or photo repair.
Why Did the Slower USB 2.0 Reader Work Better?
That does not mean USB 2.0 is inherently better for damaged cards. USB recovery behavior depends heavily on the reader's controller and how it reacts to device errors. The OpenSuperClone documentation warns that USB bridges can respond unpredictably when faults occur. In this case, the generic USB 2.0 reader simply stayed connected longer around difficult sectors, while the UGREEN reader was faster on healthy areas but dropped when errors appeared.
What Should You Do Next?
Choose the Safer Path
- The photos are irreplaceable: Stop repeated reads from the original card now. Preserve the image and log, and consider a flash-recovery specialist. Professional microSD recovery can move beyond normal file access and work at the monolith/NAND level when needed.
- You accept the risk of one more DIY imaging attempt: Resume from the existing OpenSuperClone project rather than starting over, and use the reader that stays connected most reliably. Stop if the card repeatedly disappears or every remaining read fails.
- You only want to improve the 167 photos already recovered: Work from the partial image or recovered copies. Header repair can sometimes make a damaged JPEG open, but it cannot recreate image bytes that were never read from the card, so gray blocks, shifted sections, or missing image areas may remain.
The key decision is whether the missing photos are worth risking further stress on the source card. The current 0.51GB image is already a successful recovery asset; anything beyond it requires new readable sectors from the original card, not just a different file-recovery scan.
