Field note / 9 June 2012
Windows 8 setup fails from an ISO with error 0x80070570
An installation error that appears during file expansion often points to the installation media before it points to the PC.
The error code 0x80070570 describes corrupted or unreadable data. During an operating system installation, that can mean a failing disk, a memory fault or a damaged ISO. The easiest variables to remove first are the image and the way it was written.
A download that completed does not guarantee a valid file. A write that reported success does not guarantee a readable USB device. The setup process is simply the first part of the system to notice the damage.
Rebuild the installation path
Compare the image hash with the value published by the source. Write the image again to a different USB device or optical disc. If possible, use a different port and a different writer. Then try the installation with the minimum hardware attached.
If the same error returns, test the target disk and memory. A surface check can reveal a drive that is failing under sustained reads. A memory test can expose a fault that ordinary desktop work never stresses. Document the point of failure so the next attempt changes one variable at a time.
The short list
Checks worth running
- Verify the ISO hash against the published value.
- Write the media again using a different device and port.
- Test the target disk and memory before repeating the installation.
The code is a symptom, not a diagnosis. Treat the installation media, the writer and the hardware as separate links in the chain and eliminate them in that order.
