So I have this brand new Seagate 1TB external USB hd. About a week after it was purchased, someone dropped it (not me ), and it became unreadable. Windows said the partition was "raw", and partition table recovery software was not able to restore the partition. After recovering as much data as possible with R-Studio (only got about 70% of the data back), I formatted it as NTFS (64kb allocation unit size, as it is a file storage drive and not a system drive) and ran a chkdsk /r on it, with the drive plugged directly into my mobo via SATA, instead of the USB enclosure.
- 6144 KB in bad sectors.
- Adding 96 bad clusters to the Bad Clusters File.
Now I know chkdsk is looking for bad clusters, and not bad bits, is this going to make a difference? Or will it just mean that slightly more of the drive will be unreadable (96 bits unreadable vs 6144kB in clusters unreadable)?
Should I do a hard format to write all bits to 0 to check for bad bits, or is that what chkdsk /R did?
My second question, because these are the result of an injury and not age, does that mean the drive should be relatively fine from now on? Or can this scratch propagate and make things worse? Because Windows 8 kept warning me that the drive was about to fail, although that was before I did the chkdsk, haven't had any warnings in the 5 mins since chkdsk finished. Anyone here ever had experience using a physically damaged drive afterwards? (yes I should just buy a new one, no I'm not going to)
I should also post the SMART warnings:
- Raw Read Error Rate: Current 1, Worst 1, Threshold 51, Data 646544 [WARNING! # of hardware read errors: 646544]
- Calibration Retry Count: Current 100, Worst 100, Threshold 0, Data 12 [# of calibration attempts after calibration failure: 12]
- Current Pending Sector: Current 96, Worst 96, Threshold 0, Data 777 [# of unreadable sectors: 777]
Thanks for all your help!
