[QUOTE="twizzard, post: 1838095, member: 115846"] Reading the thread, the most likely problem is with the hard drive. I have had great luck with SpinRite 6, a superb way to test and restore data on HDD and SDD from grc.com - the worst hard drive I used it on had over 256,000 uncorrectable disk errors. SpinRite took days, and said it fixed all but 4 bits (yes, bits, not sectors, not clusters), and the PC booted and ran Windows after the fix. However, SpinRite comes as a Windows program that generates a boot disk/USB drive for a PC. It can be run on a Mac but it is complicated see [url=https://kevinstreet.co.uk/2017/09/11/running-spinrite-6-0-on-macos/]Running SpinRite 6.0 on MacOS (Part 1) – Kevin's tech blog[/url] . If you purchase SpinRite 6 now you will get a free upgrade to the next update which will run natively on Macintosh. [/QUOTE]
