I'm a bit confused due to this thread: Any way to recover a file with bad blocks (CRC error in Windows)?
I recently decided on a Synology DS1815+ with four WD4000FYYZ HDDs (SHR2, which is Synology’s RAID6).
Up to now my data (primarily music) was only stored on a Windows machine with internal Western Digital HDDs (Green) without any RAID. Some of the old hard drives have some (C5) Current Pending Sectors.
Is the data damaged on such sectors or how do I have to understand that values?
How can I make sure that no damaged files are transferred to the new Synology NAS?
I'd like to run a tool that scans the old hard drives and outputs a log file that informs if some files have problems, like
"abc.mp3, XYZ.jpg" is located on a bad sector or cannot be read.
What happens if I copy the data over the network just using Windows via copy-n-paste and Windows attains such a bad sector, which cannot be read?
I already get replies from other german forums that there is absolutely no problem (with a low number of pending sectors) and that Windows never copies defective data and would bring an error message. So can I assume that all data are in perfect order when windows brings no error message?
If somebody could confirm that again, I would definitely start with the copy process.
