I think I am looking more for sympathy than help here. However, I am curious if others have encountered a similar problem... and perhaps ideas on how you solved it.
This Seagate ST31000340AS is about 1 year old now. It has always been in a temperature and vibration controlled environment.
Recently, the drive began displaying odd behaviour by way of files and folders mysteriously disappearing. A re-boot always brought the missing items back. Originally, I suspected the SATA interface (external drive). However, the symptoms have become progressively worse, now that I have the drive connected to a SATA to USB converter.
My first backup attempt (via the SATA to USB), I could move about 420 GB of data in about 7 hours before failure.
By failure, I mean I see I/O errors (see screen caps). At this point, previously viewable files are no longer accessible.
On my second backup (move files actually), I could only move about 65 GB of data before failure.
I have noticed that it has become progressively worse, and now I am lucky to move about 5 GB of data before failure. I still have about 300 GB to transfer.
Please note: This doesn't seem to be a temperature related problem because I have a lot of cooling on this drive now.
Unfortunately, this drive wasn't part of my RAID setup, so I must get everything backed up.
Has anyone ever encountered such a problem? I am really concerned because I have four more of the identical drive (but all are more recent purchases).
