I have a weird problem with a Fostex D2424LV MKII that I recently bought from Ebay.
When I bought it I noticed slight corrosion on the back panel, so I took the cover off to find corrosion to the metalwork in several places. As the circuit boards were free of corrosion and after the unit passed a thorough test of all functions, I decided to keep the unit. The MKII offers the ability to transfer WAV files and whole projects via Compact Flash cards and has no SCSI backup facilities (it hasn't got a SCSI port). I also have a MKI unit which means I can swap caddies between the two and easily move projects that were recorded live at gigs into the studio for mixing / re-recording / overdubs etc.... and backup these projects either as WAVS or project backups via CF card to a network drive...... well that's the idea anyway and it should work out.
As you can see from the pics here though,

the difference in the corrosion of the casings are notable. I've just bought some generic caddies to replace the Fostex ones which either cost an arm and a leg if you can find them. On removing the cover of the MKII unit I noticed what looked like some kind of liquid (it may have been water in the form of condensation) on the top of the inside of the cover. This is strange as neither the room is overly damp or cold. I have never seen this before with any piece of equipment and wondered whether some strange metal corrosion process is going on whereby a possible galvanised steel covering breaks down to produce water as a by-product?
Anybody got any explanation for this?
Thanks
