Damaged LTO-cartidge in tape drive
HTML-код

- This cartridge is unreadable. Tape drive (HP BRSLA 0402 / Quantum) tries to recognize it. After one full cycle it tries to self-clean head (with builtin brush) and them makes new try to read tape.

Imagine if the recording studios had access to this tape speed...would give a whole new HD quality to analog recording...
A 11.5 inch reel would last like 2 minutes
Drive reaches the end at 5:11 and rewinds, at 6:48 it uses the brush.
Brush for what? Cleaning drive machinery or trying to fix the tape?
@@hoteny The brush mentioned in the video description, which is what brought me to the video and took me a while to find, so I posted timestamps to help save time for others.
Bird in yo tape cartridge... Aka unreadable beak
Yea i think it's got no BOT and EOT marks, good to know i wanted to get some used cartridges on ebay might avoid them pay more get sealed brand new.
I've always wondered what that knocking sound is.
Its a budgie isn't it?
Haha there is a bird, yes, but that knocking noise I mean is happening when the head is hitting it's upper and lower limits, ex. just after 0:07. I've heard that knocking thousands of times in LTO drives but never knew what it was. :)
Isn't the brush inside the last resort of cleaning the head. I though it will ask you to insert a cleaning tape first, and the brush will be used after even that can't solve the reading error.
How a tape like this becomes unreadable?
I don't know how. We've bought 20 used cartridges and all of them were unreadable. Maybe they were placed near strong magnetic field or something like this.
I see, thanks for the answer.
Curious to know if they were marked as "used" or were they "recertified"?
If the tapes are used, the previous owner can have them bulk erased in order to avoid spreading the data written on. If this happened, theose media can't be reused anymore since there is no reference track on them and the LTO drive can't read the tape at the correct speed and head height. Always be careful when buying used LTO media.
Surely a magnet would just erase the data, not render the tape unusable 🤔
С какой скоростью оно считывает инфу если касета исправна?
Do you have to rewind?
No, device does it itself.
There is only 1 reel inside an lto cartridge, notice its square vs rectangular cassettes with a takeup reel built in. Therefore it must be rewound before it can be removed from the drive. Cartridges are smaller that way.
@@jonallen5078 Yes, absolutely. Unless it's an 8-track. Then you have an endless loop, that can't be rewound. ;)
