This happened today. The machine in question is running OpenSuse 13.2, on a decent sized SSD. The only symptom I can document is that once I try to boot the machine, I se the usual items flash by as the bios runs through the boot sequence, until the point where the drive from which the system is supposed to boot is sought, and at that point, I get a message complaining that no bootable device was found and asking that I connect a bootable device or insertt an optical disk from which I can boot, and then press a button to proceed.
This morning, the city in which I live experienced a power failure. While all my systems are protected by two surge suppressors (one on the mains, before power enters the building's power panel, and the other is a device into which my computers are plugged. Alas, the 'UPS' was inadequate to keep all the machines running until the power was restored.
Only this one machine (the workstation on which I work developing computer programs) is affected. None of the others (about 6 in all) have any indication of a problem.
First question is, what is the likelihood that there is physical damage to the SSD?
Second, what would be the steps to try to restore this machine? I know, in a worst case scenario, I can buy another SSD, install the latest and greatest release of OpenSuse, but first I need to see if I can fix this. I really do not want to lose the data I have on that drive. Can you point me to a few of your favourite web pages that deal with this specific problem?
First point to check (with a install or live-cd), is whether or not the SSD is still recognized (e.g. the /dev/sd[a-z] entry is there). Second point (if the entries are there), is the partition table still OK? for old/bios/mbr use "fdisk -l", for new/uefi/gpt use "gdisk -l". Both commands do only list the partition table, no writing is done. Also this command show whether or not a partion has a boot-flag set. If both prior points are ok, I'd try the "Repair" option of the openSUSE Install Medium. This is just a first help, in no way complete, or all comprehensive. - Yamaban. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
