I have a fishy Seagate HDD extracted from a troubled AIO
* Any access to it is super slow, including long delays during POST.
* It's slow in 2 computers I tried it on, and in an external USB enclosure.
* There are no read retry noises, but I still suspect bad sectors in a critical place.
* The few files I read slowly off it are okay.
* Basic tests with Seagate's Windows diagnosis tool pass okay, though take forever.
* smartctl didn't manage to read the SMART stats, maybe because of a timeout.
* smartctl does show the SMART log, though, where there are multiple reports of an uncorrectable error at LBA 0x0FFF,FFFF (=~137GB). That's a strangely round number, so I don't know if to trust it.
Any idea how to get around the slowdown so that I could copy the data without it taking forever?
