I have a hard drive that I bought 15 years ago. Western Digital Caviar
2420. 425mb IDE drive. Still works fine in my Amiga.
I recently tried to image the drive using DD under linux. While Linux
recognizes the model number and capacity, it's unable to read even a
single block off the drive. I get "ABRT" errors and "DRDY ERR" errors
during a read.
I have managed using another method to obtain an image of the drive as
I'm sure failure is right around the corner, but I'm still interested in
the problem I saw.
The ATA-1 standard was passed in the same year as the drive was made,
1994 --- it's possible the drive is "pre-standard."
The label on the drive says "AT Compatible Intelligent Drive."
Think semi-recent BIOS and new versions of linux should autodetect the
drive type ? Modify the (limited) info in BIOS? Use hdparam in linux?
P.S. drive data sheet at
WD is awesome for still having this on their site. Although I couldn't
check the warranty status w/ the serial number, what the heck!?@# :)
