How to mount a PCMCIA hard drive
Hi After a hiatus of several years, I installed NetBSD, version 10, and was delighted that several pain points I had seen in earlier attempts have been resolved. Keyboard map setting interited also to X11, and a nice ctwm default desktop setup. One platform I used was an old Thinkpad T23, 256Mb. Compatibility appears to be excellent, of course the limited memory rules out running some progrems. But on to the question: I have a "Centennial MicroDrive", 340 Mb that does into a PCMCIA card slot. Inserting it into the T23, I get these dmesg messages [ 6743.118863] wdc2 at pcmcia1 function 0: [ 6743.118863] wdc2: i/o mapped mode [ 6743.618871] atabus2 at wdc2 channel 0 [ 8339.023384] atabus2: detached [ 8339.023384] wdc2: detached the last lines two are from taking it out. Now I wonder how to mount it. It probably contains a FAT file system, but I could not figure out what device to use. Or do I need to create a new /dev entry? Erkki

Not sure why no drive is detected in your case. Martin

I assumed wdc2 is the drive here. But then one would expect it to say "wdc2 at atabus2", not the other way round. I guess I better try finding another machine with Windows or Linux where I can test if the MicroDrive hardware itself is OK. It is many years since I last used it. But machines with PCMCIA slots are getting scarce. Erkki

E.g. from a dmesg from Jornada 690 from from https://dmesgd.nycbug.org - a CF card in a PCMCIA slot: wdc0 at pcmcia1 function 0: wdc0: memory mapped mode atabus0 at wdc0 channel 0 wd0 at atabus0 drive 0 wd0: wd0: drive supports 1-sector PIO transfers, LBA48 addressing wd0: 30535 MB, 62041 cyl, 16 head, 63 sec, 512 bytes/sect x 62537328 sectors wd0: 32-bit data port -uwe
