My daughter called me about this yesterday.

She has a 2009-2010 iMac running Snow Leopard. Well, it was running, but
about five years ago, the thing would not fire up, nothing, no sound of a
spinning hard drive, no video on monitor, nothing. It was like it was
not plugged in. She took it to the Apple geniuses, who told her her the
motherboard must be dead, so she put it on the shelf circa 2013. It was
out of warranty.

She now wants to get some files, mostly pics/videos, from the hard drive.

With the help of google, she managed to remove the hard drive. It's a
2.5" 500GB Seagate SATA. She connected it to my adapter/converter cable,
similar to this one

External/dp/B002OV1VJW

and to her Win10 HP laptop. The drive spun up, but nothing popped up on
her screen. According to this article:

windows-pc/

she was expecting to get something like do you want to format this drive?

She also tried connecting to a Win7 machine, but no luck there, either.

She has not yet installed HFS+/HFSExplorer. She is going to wait until I
can help (tomorrow). But, if we are able to access the Apple hard drive,
can we move files to a Windows PC, and also open them?

Thanks.
