My HDD has become very slow?

[nesta13]

I have a roughly 1 year old seagate 250 GB SATA hard drive .
Recently it is giving problems .I had posted earlier on the same forum about the problems and the solution

http://www.tomshardware.com/forum/247208-32-hard-disk-crash-save-data

but when i tried to store the data again on my HDD back, it is showing poor write times .So i performed some test on it following are the results
this is the Write benchmark
HD Tune Pro: ST3250310AS Benchmark

Write transfer rate
Transfer Rate Minimum : 1.5 MB/sec
Transfer Rate Maximum : 1.8 MB/sec
Transfer Rate Average : 1.8 MB/sec
Access Time : 15.6 ms
Burst Rate : 1.7 MB/sec
CPU Usage : 28.9%



This is the file write benchmark
HD Tune Pro: ST3250310AS File Benchmark

This is my System config
AMD phenom 9550,2GB RAM and 500GB SATA HDD....

Is my hard disk dead or its some driver problem

****edit****

suddenly it has started working fine ...I dont now why !!!!!,still its working fine now , heres what i did

I unplugged my 500 GB and formatted 250 GB ,loaded fresh XP.
then keeping 250 GB as master i plugged 500 GB as slave ..and tried to copy stuff an it all went fine ...then i did the other way round also ,and that also worked .

still to be sure i'll run few tests on it for next few days and update here

have you given it a recent defrag?

 

[GhislainG]

You already identified in a previous thread that the disk wasn't reliable. Why would you store your data on it again? Do the diagnostics indicate that it's fine?

Here is one possibility for the low transfer rates. If the SATA drive is being run in IDE compatability mode on the motherboard, then there is a chance that the IDE channel is stuck on PIO mode wich goes about as fast as your transfer rates.

To check go to device manager and go to IDE ATA/ATAPI controllers then look at the properties of each IDE channel and look at the advanced setting tab. If one of the deveices is set to PIO instead of DMA change it. I think when I had this happen on my old IDE drive i actually had to update/resinstall the ide driver to get the change to take effect.

Also have you run seatools to check the drives health?

Check your chipset drivers as well. When I installed one of my old Seagate SATA II drives under Vista recently and hooked it up to the ULI chipset (I have my other 2 drives which are SATA I running in RAID 0 on the SATA I Sil3114 chipset) it tested almost exactly the same after Vista did it's thing/found the drive/installed it's own drivers, until I pulled the ULI Chipset driver disk out and reinstalled the drivers. After installing the right drivers, it jumped to around 85mb/sec and the seek time dropped from 17ms to around 14ms.

Thanx for the replies....
but ,all these tests were carried out on freshly installed XP .I checked about the IDE thing as well ,all my IDE are running on DMA . I am doing all this because if its dying then i can get it replaced since it is under 3 yrs warrenty.hard disks are not that cheap back here in India.I have tried having 250 gig as slave and 500 gig master,but no help there also .
