Description

Hi,

Im still trying to understand what is the best way to retrieve files in batch from LTFS. The ltfs_ordered_copy takes ages to retrieve couple of hundreds of megs and it seems the drive is constantly seeking. Are HP drives supported at all? Thanks

Z.

After 40 minutes, I was only able to retrieve 17 files (cca. 20 megs each)

```
root@pop-os:/home/rezo# ./ltfs_ordered_copy /ltfs/n64/ /home/rezo/ -r
Tape order aware copy for LTFS
Destination /home/rezo/ is not LTFS
On disk sources: 1058
Source tapes: 0
Copying on 1058 disk files with 8 threads
File copy from disk is on going: 17/1058^C^Y^Z
```
