Bought HDD month ago, Seagate Barracuda ST3500418AS. Splited it into 2 partitions with Acronis*Disk Director Suite. Installed Win XP, hdd was working great. 2 weeks ago splitted it into 4 partitions and installed Win 7 on one of the partitions and again hdd was working great. 3 days ago it started to work slower, longer copy data, loading games and etc. At first hdd was working slowly only on win7 and today it started work slow on win xp too.
Tested it with Crystal Disk Mark 3. There's results:
* MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s]
Sequential Read : 20.656 MB/s
Sequential Write : 120.540 MB/s
Random Read 512KB : 0.000 MB/s
Random Write 512KB : 0.000 MB/s
Random Read 4KB (QD=1) : 0.000 MB/s [ 0.0 IOPS]
Random Write 4KB (QD=1) : 0.000 MB/s [ 0.0 IOPS]
Random Read 4KB (QD=32) : 0.000 MB/s [ 0.0 IOPS]
Random Write 4KB (QD=32) : 0.000 MB/s [ 0.0 IOPS]
Test : 1000 MB [D: 27.0% (20.2/75.0 GB)] (x1)
Date : 2011/03/01 16:13:21
OS : Windows XP Professional SP3 [5.1 Build 2600] (x86)
I did check for errors on all partitions using win7 built in check for errors. Nothing.
HDD is regullary defragmented and checked for viruses so this is not what causing problem.
I did one big stupid mistake, i did not do slow formating after buying hard drive and was using fast formating, maybe this is what causing problem?
