Alex,

Would you mind providing some more in-depth info on reading CD-DA? I'm
reading in cdparanoia's faq:

"... Cdparanoia will read correct, rock-solid audio data from inexpensive
drives prone to misalignment, frame jitter and loss of streaming during
atomic reads"

So would a Plextor drive and/or multiple reads be necessary for extracting WAV

Depending on the type of optical media you have in your collection, it
may be wise to purchase specialty hardware and obtain specific
software for the migration process. In short, optical media workflows
can be divided as:

Accessioning workstations

Hello All,
I'm putting together a budget request for an accessioning workstation and
I'm curious what your setups are like. (For this discussion, accessioning =
everything up to the point of AIP transfer to archival storage.)
I'd really appreciate it if you could take some time out of your Friday to

Are you creating raw, aff, or some other image format? Short answer:
checksums should match if you are creating raw images but they won't if you
are creating images in another. Long answer: only the raw format keeps the
bits in their original order exactly as they came off the disk whereas the
others either add metadata, perform compression, or both. FTKImager is

FTK Imager-generated checksums

dorryfch...@gmail.com (Dorothy Waugh) — Wed, 15 May 2013 18:28:51 UT

Hi all,
We have a question about the checksums generated by FTK Imager. Recently we
noticed that the checksums generated for our image files by WinMD5 and
Checksums For Windows do not match the checksums generated by FTK Imager,
whether during the imaging process or later on.
For example, I created an image about a month ago using FTK Imager. When I

Re: [digital-curation] CRC and file transfer

MD5/SHA-1 are basically free on any modern system compared to the overhead
of the actual transfer (e.g. even my 3-year-old laptop can run SHA256 at
gigabit ethernet wire speed using a single CPU core; md5/sha1 are
considerably faster) so there isn't a strong pressure to do this for
performance grounds unless you have both extremely fast network/storage

I use the free TeraCopying all the time when loading materials into dark
storage. Like you we generate/verify checksums (SHA256) at other points in
the processes (before and after) and TeraCopy is great for a quick and easy
copy/verify transfer when you don't need to retain the checksums from the

I'd be interested in responses too. I use TeraCopy personally and
somewhat professionally. Haven't fully adopted professionally because it
uses CRC checksums instead of MD5 or better. Unfortunately, the paid
version does not allow you to use MD5 either. It's a great utility. If
there are alternatives that use MD5, would love to hear about it!

Gretchen,

We have used that tool successfully here at Illinois. I am not aware of a tool that uses MD5 or SHA checking on both sides. Teracopy been useful to us, since it has caught several failed file transfers and while, while cutting the step of a manual check process, which would complicate the workflow quite a bit unless we were to develop some kind of automated checking tool. (if there is one out there, we'd consider using it.)

CRC and file transfer

gm...@eservices.virginia.edu (Gueguen, Gretchen (gmg2n)) — Tue, 07 May 2013 15:47:01 UT

Does anyone have any thoughts about using a tool that uses CRC to verify transfer instead of a MD5 or SHA checksum. I was looking at this tool TeraCopy ([link]) to use to transfer some data from my local machine to network storage because it aids with the speed of transfer. It uses CRC to check that the transfer is complete and the data is fixed and I'm wondering if that would be sufficient without doing a separate check (MD5 checksums are being created for each file as part of accessioning, this would just cut out the step of doing them again and checking post-transfer).

Digital curator - capability & competence

Hi,
I'm a LIS under graduating student and I'm researching about Digital
Curation. More precisely about preservation metadata. As I'm still on my
first steps in this project, I'm collecting resources to read and analyse
what to write. So, what I'm having some difficulties to find are the
capabilities and competences needed to be a digital curator. I aim to
