Hmmm....
I couldn't work out how to query it, so I had a go at just setting it
explicitly instead:
hdparm -W 0 /dev/hda
- /dev/hda:
- setting drive write-caching to 0 (off)
- HDIO_DRIVE_CMD(setcache) failed: Input/output error
Could any one tell me why this is likely to fail?
If its any help, I also got the -i output from hdparm:
hdparm -I /dev/had
-/dev/hda:
-Model=TSSTcorpCD-ROM TS-L162C, FwRev=N203, SerialNo=
-Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic }
-RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0
-BuffType=unknown, BuffSize=0kB, MaxMultSect=0
-(maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
-IORDY=on/off, tPIO={min:482,w/IORDY:120}, tDMA={min:120,rec:120}

-UDMA modes: udma0 udma1 *udma2
-AdvancedPM=no

-* signifies the current active mode
Many thanks,
