- In linux all IDE disk listed as 'hda' and SATA as 'sda'
-
- In my case my IDE disk mapped as SATA
-

- but i have no SATA disk and even no SATA port
-
- Here is the performance of my HDD-
-
- ~$ sudo hdparm -tT /dev/sda
-
- /dev/sda:
- Timing cached reads: 642 MB in 2.00 seconds = 320.61 MB/sec
- Timing buffered disk reads: 58 MB in 3.04 seconds = 19.05 MB/sec
-
- Which is not a good answer given by `hdparm`
-
- My hard disk is slow..
-
- also DMA seems to be not working...
-
- $ sudo hdparm /dev/sda
-
- /dev/sda:
- IO_support = 0 (default)
- 16-bit)
- HDIO_GET_UNMASKINTR failed: Inappropriate ioctl for device
- HDIO_GET_DMA failed: Inappropriate ioctl for device
- HDIO_GET_KEEPSETTINGS failed: Inappropriate ioctl for device
- readonly = 0 (off)
- readahead = 256 (on)
- geometry = 4870/255/63, sectors = 78242976, start = 0
-
- I check $lsmod command it shows me that the "libata" modules are loaded
- and there is no ide-disk and ide-cd
-
- modules.
-
- I think "libata" controls SATA disk.
-
- Is my IDE disk is controlled by SATA drivers?
-
- or it is the natural speed of my hard disk?
-
- It may be a Bug. I don't know!
