Re: [ARSCLIST] To keep the tapes or not

["Nigel Champion (ARTS ANT)" <n.champion@xxxxxxxxxxxxxx>]

There some issues you might consider:

a) You generated the WAV files by ripping the CD-Rs but now have another
query on ARCSLIST about disc extraction software.  Are you confident
your ripping process was accurate?

b) Were the CD-Rs tested before despatch to the other geographic
locations?  Ripping is not a thorough test.

c) Is the integrity of the stored WAV files being verified using MD5
hash or similar?

d) If you discover that the CD-Rs (and the resultant WAVs) are
problematic because of a poor unverified burn or a faulty manufacturers
batch, will you be able to go back to the originals and repeat the
digitisation?  Keep in mind, it is likely such a repeat digitisation
would be put off until you have completed the digitisation of the whole
collection.

My two-cents-worth is to hang onto the 1/4" copies until you are
confident these issues have been resolved.  After all, the WAV files are
now your preservation copies.


All the Best

Thank you both Angie and Russ,

The originals consist of acetate 1/4" (some of which have vinegar
syndrome and are in very bad shape), polyester 1/4" (good shape), but
the vast majority (95%+) are cassette and they are all in good shape
too.

As I said, I will be retaining all originals.  So, the question remains,
why keep the 1/4" copies, which are one generation down in the analog
domain, when there are 2 CDs (protected by geographic separation) and
.wav files on site of all originals?

Thank you again for your consideration and responses.  It is great
having other perspectives to inform my thinking.

Sincerely,

Kevin Irelan
