SATA и R/W multiple sector transfer


0

Хотел спросить, имеет ли значение, что: >> R/W multiple sector transfer: Max = 16 Current = 1 Все таки на обычных иде-дисках он всегда 16. Этот диск sata, ядро 2.6.18, драйвер nv_sata (мать Nforce4).

Собстенно, вопрос возник в связи с тем, что поставил dc++ и при расшаривании этого диска он вылетает c сообщением "ошибка шины", а в логах остается примерно следующее:

ata3: EH complete sd 2:0:0:0: SCSI error: return code = 0x08000002 sda: Current: sense key=0x3 ASC=0x11 ASCQ=0x4 end_request: I/O error, dev sda, sector 454359327 ata3: EH complete SCSI device sda: 488397168 512-byte hdwr sectors (250059 MB) sda: Write Protect is off SCSI device sda: drive cache: write back SCSI device sda: 488397168 512-byte hdwr sectors (250059 MB) sda: Write Protect is off SCSI device sda: drive cache: write back

Что интересно, DC-QT, например, таких проблем не вызывает, но он и расшаривает не с так напряженно. Вот я и думаю, кто виноват, прога или винт кончается?

На всякий случай - hdparm -I /dev/sda
