Cannot restore data backed up in USB drive.
Hello linux users,
I'm in a bit of a bind. I was having trouble with an Ubuntu installation upgrade that left my system crippled, so I decided to change over to OpenSUSE.
The problem I'm having is with how I choose to back up the data.
I only had one USB drive available, but it was formatted with NTFS. I tried backing up my data directly to it, but the Ubuntu system began giving me I/O buffer errors. At a first Google glance, I got the general impression that this seemed to be a distribution problem that came up when one made excessive demands on the duress of the transfer. I was backing up over 100 gigs of data from an ext3/4 filesystem to an NTFS, and I was trying to do it from a console on my crippled Ubuntu system, so I just assumed it could have been any number of things.
Since backing up data into the drive didn't seem to work, I tried running chkdsk /F on the drive from my Windows partition. It began taking a ridiculous amount of time, and it kept coming up with read errors, but I still kept chalking it up to the possibility that the filesystem had become corrupted. You can probably tell where this is going.
I eventually reformatted the drive into ext4, and tried backing up all of my files from an OpenSUSE LIVE session. It gave me no error so I foolishly assumed that transfer had gone well. Now, I'm trying to copy back the files and it keeps giving me input/output errors. The hard drive was bad but since it gave me no error during the write operation, I had just assumed it had gone flawlessly. The drive itself isn't making any noises, it hadn't given me any problems before. Since I ran chkdsk I would have half expected that any bad sectors would have been invalidated, but that was a short-sighted expectation.
So, what to do?
Now, I'm stuck trying to figure if there's anything I can do to salvage it.
I'm principally concerned about two files, each of which is 32 GB, but I'm not certain I can restore them from the original hardrive given that I've repartitioned, reinstalled, and have already tried to restore my files there. The only option is to keep trying to restore them from the USB. These files are also encrypted.
I only wish I had had the resources to create a decent RAID backup solution instead of relying on the half-assed backup attempts where I failed to even confirm the data had been correctly backed up after doing so.
I'm also beginning to question if I should continue to stay with any linux distribution. I'm largely to blame from this failure, but like most failures, it has been promoted by a series of deficiencies between the surrounding environment. I'm going to try reformatting the drive to NTFS, and copying files to it to see if Windows would have noticed the drive was bad just for laughs. Windows would certainly require much less maintenance, and I haven't had the repeated degree of problems I've had during distribution upgrades in Ubuntu and OpenSUSE. Maybe I'm just not cut out for the upkeep a Linux distribution requires.
