Hello,
I've a friend's HDD I need to dd+fix; it's attached on a Sharkoon USB3 disk enclosure. As the disk has some bad blocks, the umass driver keeps detaching it after 5 retries, which is PITA as I need first to do a dd of it. It's a FreeBSD 10 box.
Disk is nicely attached:
I try to make an image file first:
But the disk detaches after the first 5 errors are found:
I've read/tried all those "usbconfig", "umass quirks", "camcontrol", "sysctl" commands I could imagine are related to this problem but had no luck so far. The other question in this context: usbconfig was unable to list/find/cfg the once-detached da11 - is this by design? The device just disappears - I thought I could rescan/powerOn, but it's just vanished.
Any umass/disk guru here
? As a very last fallback I would attach it onto the MB SATA directly, but I would like to know if it's possible to do it via USB, as it would be much more usable!
Thank you,
Andrej
