4 mm DAT tape users

[Marauder2003]

Any DAT data tape users here? Cleaning out for my move to Vegas. Found a stash of these tapes. Also found my Dad’s bulk eraser. I found it could erase 2 floppies at a time. I have no way to test how well it can erase the DATs. I don’t remember if they were pre-formatted. If I bulk erase a tape is it still recordable again for data? I see they sell on eBay but I don’t want to list them if my bulk erasing will render them useless.

Sell them on Ebay. Someone out there will need them.

I will if bulk erasure does not somehow make them useless. I don’t want my data in the wild.

I still have a DAT recorder but haven't used it in a long time . . .

Well, I used a bulk eraser and (hopefully) zapped them. They are now on eBay.
