Could the people experiencing issues with this hardware, please give the attached copy of hdparm (pre-release) a go on their troublesome systems, and report back? This version uses ATA_12 for PACKET IDENTIFY and any subsequent commands to a PACKET device (CD, DVD, TAPE, etc..), and ATA_16 for everything else.
.. Mmm.. got that wrong, I guess.Let's try again. Does the attached copy of hdparm work for everybody now? It uses ATA_16 by default, for everything.
And forces ATA_16 when it thinks it is talking to an ATAPI device. Plus, it uses a sector count of one (1) for all IDENTIFY commands. Note however, that USB-SATA bridge chips from other vendors have always worked correctly without the need for the sector-count field.Eg. The bridge that Western Digital uses in their external enclosures has no trouble following the SATA/SATL spec of "n/a"
for the sector-count field. Cheers Mark
