I've had an Intel 80 GB hard drive running well for a year on this 15" Acer notebook. Then:
Occasional fsck error message booting
Got a machine check and automatic reboot
Ran trim to clean up
A couple days later would not boot /dev/sda1. Machine check and a bunch of error messages. Nothing much is up at that early stage so I wasn't able to get error messages short of a camera.
There are three bootable images. I was able to get the third one to boot. Would not connect to network wired or wireless.
Booted up on a USB 80 GB SATA drive everything worked.
Busily copied off my files from the SSD, home, archive, etc.
Removed SSD and put the SATA drive in the notebook.
The SSD is in the USB case if I want to access any more files.
Just installed tahr on the now internal SATA hard drive....running like it is supposed to at this stage....
BTW, I've been running a USB SSD on my netbook with saucy, tahr, etc. No problems yet...
