If I use a crap HD to copy audio files, would it cause any problems?
Oh God, why is this thread still going on. Just copy the files. If you had experiences where things did not seem to work then try to work out what happened. The most likely problems are mistakes like copying files not fully written to disk (e.g. Pro Tools session not closed before you copy), the disk not being properly unmoubted, or an application bug in Pro Tools.... silent filesystem or disk block level corruption are not worth worrying about. Deep corruption you expect copies to fail. But if you don’t have confidence in a drive trash it.

Re: If I use a crap HD to copy audio files, would it cause any problems?
Furthur more, I have had an experience of copying audio files to a very very cheap USB stick , and to another computer, and I got half of the audio turns into white noise... It may be damaged due to unmount...
So wondering if a super cheap USB stick, which may easily have bad blocks, once the copy is finished without any errors, can we really trust all the audio files are the same as original.

You are not helping yourself by having problems then leaping into a specific deeper area and asking things about like “bad blocks” which have a specific technical meaning, are hardware related, below the level of files or the file system, and *will* cause reported errors on a file copy. Are you writing your own copy program? Filesystem? Working with a debugger trying to reconstruct a corrupt filesystem? No? Then stop asking questions about bad blocks etc. and start working out if you did anything that could cause this (much more likely), or you can work out if you have something like a corrupted filesystem or device (much less likely). So again worry about things like... Are you sure Pro Tools (or any other program/utility) fully exited/closed the session, with no errors reported, before you started copying files to the transfer media. How exactly are you unmounting the transfer drive? How exactly are you copying files? There are three filesystems involved here, the source, transfer and target one. One each one compare the files, starting with generating a checksum for each file in the session. Where are they different? What exact type of filesystem is on each device? What exact OS/version is on each computer? Is the file system you are copying from or too or on the transfer device corrupted. Run a file system check utility. What does it say/do? Look at the SMART diagnostics (or equivalent) for each of the three devices. Is this reproducible? How exactly? Sent from my iPad using Tapatalk |

meaning, when using even a questionable HDD or SSD, as long as I have copied the files out without seeing any error messages from OS X, then I can trust that the files I copied is the same/good as original and I should not worry. Correct?

Re: If I use a crap HD to copy audio files, would it cause any problems?
You've gotten a lot of great info here from other posters, but I gotta ask, if you're really this paranoid about this particular drive in question, why not just buy another one? They're not exactly expensive these days.
Seems like it would put your mind at rest. Sent from my iPhone using Tapatalk |

And a very likely cause of data being wrong inside a file is not corruption of the filesystem of file, its the application program writing garbage into a perfectly fine file. So back up and go check every step here by checksumming the files at each stage and confirm where they differ. (not what any application. including Pro Tools tells you is in the file, but actually use a checksum to see the actual files on disk differ or not). Again this should not be a hypothetical question. If you are having issues, work to find out what is actually going on and stop asking people what they think. |

The problem is , I don’t know if the copy has caused any issue, maybe it’s not like last time half of the audio turns into white noise, it could be only 1 second of white noise... That’s why I asked if if the target disk is in great shape,the copy completed without any errors, and the mount/unmount is successful, application like pro tools is closed totally before copying, then at this time should I trust the copy is perfect.
