It's been probably 20 years since I've rolled a kernel... oh, my.

The modprobe advansys found the driver (there's an advansys.ko.xz file in the right place for it) but doesn't grok the card, I think.
Beginning to wonder if spending $50 or so for a new PCIe single-ended SCSI card might be the best solution.

All older tape drives require a SCSI connection. SCSI interfaces, on the other hand, vary significantly. Both the physical and electrical connections are the same.

If the information on the tape is valuable, it may be worthwhile to hire someone to read it for you; however, this will be costly. I understand that different types of data loss necessitate various ways to recover.

Long ago I used tape backups extensively. I used tarballs which was common usage at the time. Here is some docmentation for tarballs.

jailbait, the OP has not been around for a couple of years and the previous posts are probably spam.

I can also recommend that you contact highly trained DATA RECOVERY engineers, who are adept at rapidly and precisely detecting the problem as well as determining the best method for retrieving the files that will be most beneficial in your specific situation.

Fry's went belly-up a couple of years ago. RIP.

If you see the SCSI controller in the boot sequence, that's a good sign.
I seem to recall that when I was using SCSI tapes, I had to run an "stinit" command along with a config file (like one of my ancient config files) before I could actually use the drive"
Code:
manufacturer=DEC model="TZ88 (C) DEC" revision="CC34" {
mode1 blocksize=0 compression=1 }
manufacturer=SONY model="SDT-7000" revision="0167" {
mode1 blocksize=0 compression=1 }
etc.
to initialize the tape device. Sadly, I don't see "stinit" being available, at least not in the normal OpenSUSE repositories. Perhaps it's no longer necessary. (I used to have an old TZ877 7-tape library and the more I think about it, I didn't need to do anything special to access it, load/unload specific tapes, etc.)
Try using the "mt" command (Ooops! I guess it's "smt" nowadays.) with the non-rewinding tape device to move the tape forward one/two tape marks and then rewind. ( Write-protect the tape(s) first... just to be on the safe side.) If that works, I suspect you're all set.
Quote:
* This is a one-off, a very badly belated recovery. The machine that the tape drive was originally in was two or four computers old (i.e. probably around 2000-ish). When I retired that machine, I vowed I would get that straightened out ASAP, and ... well, here we are about 15 years later.
|
No apologies needed. (I still have an old project to recover files from old floppies. Phase 1: recover the 3.5" diskettes. Phase 2: reflash the m'board so it'll recognize a 5.25" drive and recover those.  )
Quote:
* I’m not certain what format the tapes are in, but I’m about 90% sure they’re cpio or afio (same thing but with built-in compression).
|
If you can get Fedora to move the tape, and the contents are cpio (not sure about afio) you have a chance of recovering their contents. The compression might be a problem.
Can't be much help with the HFS disk other than to comment that the mount(8) command still lists options for use when mounting partitions containing that filesystem type. You're likely in good shape there.
One caveat: Long ago, I had problems trying to have both disk and tape devices on the same SCSI controller. I wound up using an old DEC KZPAA controller for the tape drive and an Adaptec (various versions) for disks. YMMV.
HTH...
... and good luck.

Fry's closed down on 24th February 2021 - i.e just a year ago.
The post you responded to is from 2018 - just like the rest of this thread (until spammers bumped it).
