       All prepped and ready to co-present 'Bit by Bit: Preserving Collections on Digital Carriers' with @roxiruuska at #BDCH23 on Friday this week. Unfortunately, I could not be there in person so I hope the technology gods are on our side for hybrid presenting! See the program for more details: https://aama.net.au/program/

       Some stats from our presentation last week: Over 18 months our team processed over 2,000 carriers. We record the status of each carrier as Success = all material was transferred, Partial success = some material recovered, Failure = unrecoverable, Duplicate = duplicates another carrier, Review required = managerial assistance or decision, Blocked = no hardware to read it, and Null = blank. So far we have an overall success rate of almost 80%.

       Failure rates are highest in 5.25 floppy disks (32% of 235 disks), followed by 3.5 floppy disks (9% of 763 disks). 2% of 1,207 CDs and DVDs completely failed with 13% only partially recovered.

       @twizzt so far we have only come across one data cassette, which is currently 'blocked'. From our research, it is a 'streamer data cassette' which requires a very specific drive to read (which we can't source) and can't be extracted as audio and converted to data as some cassettes can. 😭

       Anyone have any experience disk imaging 'Lanier' 5.25 floppy disks? Our Mitsumi D509V5 floppy drive attached to a Kryoflux does not recognise the disks. They have multiple index holes, which indicate where the 'hard' sectors start according to this web page: https://cowlark.com/fluxengine/doc/disk-aeslanier.html

       @foone Kryoflux says that there is no disk in the drive, so can't capture a raw stream. The only other equipment we have is a Mitsubishi MF504C-327UW 5.25 drive, and greaseweazle and FC5025 floppy controllers. I haven't tested any of this myself, so i'm just going on what my team member has told me they have tried so far.

       @foone oh! I forgot we actually have an additional modified drive specifically for flipped disks and I didn’t think to try it out for these disks. Will try that with Kryoflux, but also check out the greaseweazle options
